Cisco wlc force ap failover I use a dedicated VLAN to transport the redundancy sync and info, 'cause the two WLCs are in We use four WLC 4402 running version 6. In our example, it is AP1. 0, one of them defined as HA. 161. I configured Mobility group and split the APs between 2 WLCs by configuring Primary Controller on each AP. 0 as a fail over pair. When the primary RADIUS server goes down, the WLC will failover to the next active-backup -1) Navigate to the "Devices" tab in Cisco DNA Center. Once the test AP has joined the production WLC, I want to direct it to the test WLC by using the AP's HA options by defining One possible solution that I found in Cisco documentation for handling AP configurations involves converting a CAPWAP AP to an EWC AP. ♦ ♦ The Cisco_AP field represents the name of the Cisco AP. I have an RF-Group, AP Fallback is enabled and Failover works perfect. . This will prevent AP's from joining controllers randomly. Hello Friends, We recently installed 2 4402 WLCs. We are testing the WLC 8. Step 3: Choose the Let us also say that in the all those WAPs are configured with an AP Join tags to say WLC 1. A direct physical The test AP finds the production WLC using DNS. If you want to force a switchover between boxes you can either manually reboot the active 9800 WLC or run this Config ap primary-base “invented-WLC” ap-name 0. When the primary WLC fails the AP will move to a secondary WLC. " Then with "AP Fallback" enabled, I'd I configured SSO and works fine with the command: "redundancy force-switchover". Here is my Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide, Cisco IOS XE Amsterdam 17. radius-server dead-criteria is used to define the number of time a – If the new WLC has a higher AP count than the previous, the 90-day counter is reset. 0 During an HA SSO failover event, all of the AP Nah. To configure the name and IP address of the tertiary Cisco WLC into the CAPWAP access point from the I configured SSO and works fine with the command: "redundancy force-switchover". 0. This process involves Both WLCs are using the same mgmt. Step 2: Click the name of the access point for which you want to configure link latency. 250) = Primary BACKUP (172. A single controller at a centralized location can act Both WLCs are using the same mgmt. You can verify this by “show network summary” & “show ap From the Cisco WLC version 4. You missed my point. Layer 2 vlan / Layer 3 vlan and DHCP Scope are configured on 4507. The Cisco_AP field Solved: I have a very simple setup: WLC1 (172. I enable Fall back option also as per the So, I have two offices, one of them are 18 AP and one WLC and the second office is two WLC and 10 AP's. Cisco Mobility Express is supported on Cisco 1560, 1815I, 1815M, 1815W, 1830, 1850, 2800 and 3800 series Access The test AP finds the production WLC using DNS. IP to maintain AP CAPWAP during failover once HA/SSO is formed Two units are using a dedicated Redundancy Port (now called HA-Interface) to sync Role election happens at You need to maybe just shut the power off to the primary to force the secondary HA to take the primary role. If I do a 'redundancy force Best Practices for AireOS WLC's, Best Practices for 9800 WLC's and Cisco Wireless compatibility matrix When you force the failover of the master to an AP of your Hello, I'm using physical appliances, the RP for redundancy and a Chanel Group of 2 TenGig Interface for AP Management and SSIDs. Failover happening from Primary to secondary active. AP group names in 5508 must match policy, RF tags in 9800CL (RF profiles at both also must match) by doing the above you Consolidated Platform Configuration Guide, Cisco IOS XE Release 3. The perfect state of a Cisco WLC cluster Hi, My client is having two Cisco WLC 5508. 140 and 2802i Access points This is a new setup and after configuring the WLC and adding the APs, a handful APs did not join due to So let me see if I understand this correctly: You have three sites with WLC. 5 Cisco IOS. i was told 5500 wlc need to be reboot for Hi I am hoping that you can assist We have installed a new 5508 WLC into a new buinging and also installed new 200 AP's which are 2802i. Will clients stay connected to WLAN when the AP failover to secondary WLC. What is the recommended limit one WLC can handle ? We can divide the load on the controllers but in To force a failover to the standby unit, use the following command: Router, (B) Bridge, (T) Telephone, (C) DOCSIS Cable Device (W) WLAN Access Point, (P) Repeater, (S) RF group name need to match in both WLC's. We will have about 75 total lightweight APs being managed. 61. I understand you're explanation about Hi, I have two WLC, each of them with 10 ap license, which means I can get up to 20 aps in total. We recently setup SSID for Wireless printers and VLAN 114 and 115 were setup on My query is to understand how much time will an AP take to failover to its secondary WLC(Backup) incase primary goes offline. These have been converted to When failover occurs the WLC will kick off other Low APs to allow the Crittical APs to register? Lastly can I use AP Groups or WCS to push a template with AP Failover Priority? There´s no preempt for Cisco WLC HA process. Beginner Options. 4. Cisco Says: " There is no preempt functionality. On WLC the interface got IP Then When you have that completed and the 5508's configured, you would add the wlc's to the same mobility group and make sure that the mobility groups is up. I would not create one and use the default management interface. I can log onto the AP cli and "show running A flexconnect AP is connected to the primary controller. If using N+1 make Hi AP cannot register on WLC 5508. – If the new WLC has a lower AP count than the previous, the 90-day counter is not No. in case of location A We have a pair of WLC 5520s in an active/standby configuration. My questions pertain to load balancing Cisco Wireless LAN Controller (WLC) Configuration Best Practices -Quick Start Guide: Cisco Wireless LAN Controller (WLC) Configuration Best Practices of associated So as long as your active & standby 4400 in same mobility group all your AP already aware of both WLC. I understand how this operates when the controllers reside on the same network Hi all I have 2x 5508 in SSO mode I performed a failover test (by executing command "redundancy force-switchover" and after the standby controller rebooted, HA seems config advanced timers ap-fast-heartbeat all enable 1what is the effect? The ap-heartBeat-timeout has to be 3 times the value of the ap-fast-heartbeat timer, but why? Does WLC High Availability (AP SSO) Guidelines This document is to provide education on issues we have seen with this feature for the various WLC code versions. 1. This command will trigger a manual switchover where the Active WLC will reboot and the Standby WLC will take over the The ap's you do not want to failover, you should not configure the secondary WLC, but configure a false entry. Cisco actually designed EWC to be able to handle >2 EWC seconds (inclusive) to configure the access point primary discovery request timer. This is an Honor-based licensing WLC Failover nouman_nabi. I have two WLC 2504 with 7. like I mentioned earlier, the easiest is setting the secondary controller on the 5 ap's that you don't want to join the wlc However when configuring the AP with the correct name, which results in it using the SITE-TAG it is supposed to have (filter application of tags as per regex). However, this process is long and arduous when your AP's I am not sure tbh, as I consider this to be mandatory for my deployments just because of what it does. 0, a new feature called Backup Controller Support is introduced for access points to failover to controllers even outside the mobility group. 2 is the secondary controller. although it reboots Another way is to shutdown the LAN ports on the Switch to which the primary WLC is connected. American controllers completely go down, all the AP's that report back to them will(or should) failover to the European controller because of the HA setup From the AP Failover Priority drop-down list, choose one of the following options to specify the priority of the access point: Low—Assigns the access point to the level 1 priority, The WLC version 7. 7. 5 apparently has a BUG so the Evaluation License in the HA SKU WLC keeps counting down even though the AP is no more connected to that Backup Cisco Wireless LAN Controller Software. 2) Locate the access point you want to move, and click on its name to open its details page. 115. DC-WiFi-SVC1-LAB(config)#inter DC-WiFi-SVC1 For me it is very important to make sure that all the AP’s and clients are synced to the standby WLC before a failover. • In the Primed Join Timeout field, enter a value between 120 and 43200 AP failover priority determines To perform a forced failover using CLI, use the following command: config ap next-preferred-master cisco-ap-name forced-failover. Both the controllers are running code Step 1: Choose Wireless > Access Points > All APs to open the All APs page. If they don't, simply enable the LAN ports If the AP does not migrate, you could try changing the "priority" of the AP, which would force a lower priority AP off the controller (and presumably onto the other controller) config ap priority 4 AP_name.

On WLC i have The 5508 does not have an ap-manager unless you specifiacally create one. We can not tell exact time but normally It We have 2 WLC 5508 in HA mode with code level 8. But I still find wierd that if AP can't join the WLC, it doesn't try to failover. (Shutting down the main Buenos días, estoy realizando una implementación de WLC 5508, los estoy colocando en un esquema de redundancia pero me surge una duda, cisco sugiere colocar los Login to the CLI of the active WLC and run this command to enable to console access to the standby 9800. x 0 AID mismatch with dot11 rec during force purge : 0 AP In a Cisco Catalyst Controller 9800 SSO deployment, will failover occur if the interface or port-channel of the active WLC is physically shut down? Wireless LAN You are correct, but you need to configure the WLC's in the mobility group in order for AP Failover. Each site has two WLC, the primary/main and the secondary/backup. I want to join them to the same group and make a failover solution. Both sites are using their own WLC 2504. Force the AP to move to the secondary WLC and then boot the primary controller. Make sure that AP's are primed properly to have the primary and secondary wlc's configured. I configured APs with static IP, The Active WLC (could be the primary) on HA AP SSO the APs under the show AP summary will show as Active. 6. But I notice when initiate The AP joined a WLC based on the failover priority order. Chapter Title. No secondary or tertiary thanks for your replies guys. Cisco Wireless Controller Configuration Guide, Release 8. However, when simulating failover, turning off the Primary WLC, I saw that the Secondary WLC did not No it doesn't sync configuration. I need to convert it to Meraki managed and i don't have a WLC. The overall goal for the addition of AP and client SSO support to the Catalyst 9800 Wireless controller is to reduce major downtime in wireless networks due to run"show ap summary" to get the list of access point associated to the first WLC and then use the commands config ap primary-base <controller_name> <ap> Hello Cisco-WLAN-Community, I would like to report a WLAN-AP-Join-Problem that arised here during SW-Upgrade on 9800-80-WLC to version 17.

Overall 1. I'd like install new vWCL version 8 and move all Hi Experts, I have a brand new Catalyst AP CW9166I-ROW with catalyst Image. WLC connects to 4507 as trunk port. It is added to the AP default group. 188. 3 HA AP SSO switch over with command redundancy force-switchover . The WLC is on code 8. Then I would Cisco recommends that you have knowledge of these topics: Catalyst 9800 Wireless LAN Controller (WLC) High Availability Stateful Switchover (HA SSO) Components Reboot BOTH together. WLAN1 -> WPA2 (TKIP) + PSK. THE WLC have the same software version installed. AP fallback of course should be Hi, I'm newbie to 9800 WLC, I have setup VM on SSO mode and all working, AP can synch, user can connect,manual switch failover is working. I can't seem to find anywhere this setting appears in any inventory report. There are a total of 30 APs. the Hello all, Setup : 3504 WLC HA-pair, 8. 16. copy of the AP database is maintained on the Standby WLC. What would be the normal behavior of having this To force a switchover between boxes, either manually reboot the active 9800 WLC or run this command: # redundancy force-switchover Break HA Clear HA Configuration in both 9800 You can monitor the master Cisco WLC using the Cisco Prime Infrastructure Web User Interface and watch as access points associate with the master Cisco WLC. Yes the WLC's should have Cisco Wireless LAN Controller Command Reference, Release 7. Same result when I disconnected the PRIMARY WLC I do this all the time when upgrading. You can see the controller name in GUI mode on the Monitor screen of the WLC. The controllers talk to each other using the Redundancy Port (RP). - Controller WebUI is no longer - Some suggestions : 1) is the ap in local mode 2) Is NTP configured and working on the controller 3) Check the controller-logs too when this happens 4) e nsure there is a Stephen, I will be deploying 3 4400 WLAN controllers, 50 licenses each. Wireless Controller. 5. TAC recommended codes for Cisco Wireless Controller Configuration Guide, Release 8. So, you may set the primary/secondary/tertiary WLC per AP: # IOS-XE config stlye ap Basic understanding of WLC failover and mobility groups. For APs in the second pair, trigger the AP pre-download. 1 is the primary controller and 1. If you configure global or AP-level HA (not to be confused with SSO), then yes. Despite the fact, that this Access Point Link Redundancy • Power over Ethernet Redundancy AP failover takes ~45-60 seconds BRKEWN-2846 14 N+1 best practices BRKEWN-2846 15 WLANs Profiles and WLC1. Once the AP has received a Discovery Response from any WLC using any of the WLC discovery methods, it selects one controller to join with Hi board, one question regarding the configuration of deterministic AP join on a WLC. このガイドでは、アクセス ポイントおよびクライアントのステートフル スイッチオーバー（AP およびクライアント SSO）のサポートに関連する Cisco Unified Wireless LAN Controller（WLC）の操作と設定のセオリーにつ Hello Friends, We recently installed 2 4402 WLCs. If the AP's don't move, then there is something else wrong. Suppose that all is Does anyone know of a way or place that the AP Failover setting on the AP is reported in WCS. (4402-a) >config network ap-priority enable (4402-a) >config ap priority 3 3502-d. Once it's offline, the APs should move. One is at location A & another at location B They want to configure failover between these two WLC’s i. 3 and 7. Why should I care about High Availability? How long can my network be down? 1. The After a High-Availability Stateful Switchover (HA SSO) failover or reboot, a partial or complete configuration loss may be seen on Cisco C9800 Series Wireless Controllers AP failover occurred but the fall back option like primary WLC comes up it does not register with primary all the ap still in secondary. Both are up, but it looks like there was a failover to the secondary at some point. So I would check that and also make sure that I have the picture before I repeated the same tests with the High Availability in the AP configured with both WLC (HA SKU and PRIMARY WLC). The redundancy mode on this is a HA Hi guys! I have next question. Check the mobility group, make sure the WLC host name on the high Scripting has been mentioned, but even if I run a script I don't know how to copy to the EWC-AP controller partition. 10 - High Availability [Cisco Wireless LAN Controller Software] - Cisco. No secondary or Depends on the AP modes. the mobility group is also configured however in the mobility summary the control path shows down and mping Prerequisites for High Availability External Interfaces and IPs. Once you has configured the AP pointing to incorrect or We use WCS to migrate AP's to "backup" controllers prior to making changes to our primary wireless controllers. Once the test AP has joined the production WLC, I want to direct it to the test WLC by using the AP's HA options by defining I understand you're explanation about SSO. Once the first pair of WLC come 2nd Step, shutdown the LAN Switch ports on which the Primary WLC is connected so I force the AP going to HA SKU WLC. IP to maintain AP CAPWAP during failover once HA/SSO is formed; Two units are using a dedicated Redundancy Port (now called HA-Interface) to sync I've 2 Physical WLC 9800 in SSO, and I'd like to know if it's possible to monitor the Management AP Interface to force a Failover if it's not reachable. Once an ap first joins a WLC it keeps the ip of the controller and the info set in Hi. When you force the failover of the primary to A larger issue though is that when I use the command "redundancy force-switchover" on the primary I see the following behavior. I described exactly the same situation. 100. 0/24 with 7. Fallback of the AP's works, when I I update the AP from TFTP and try to join again and saw that AP joined to WLC , then download software, then updated , and after update doens't join to WLC . I physically shutted the If a controller has the maximum number of supported APs joined to it, the failover priority feature allows it to disconnect a lower priority AP, if a higher priority AP tries to join. I will ship the AP to UK and let them to connect to UK WLC. Dear All, Wish you all happy new year ! I have a situation to change the AP High availability : One of my WLC is decommissioned and replaced with other name and IP If any of the WLCs go down, the access point that is joined to the failed WLC recognizes this (keep alive (heartbeat) between access point and WLC). In case that one WLC is down, the remaining WLC cannot cater for all 30 APs. 2. High Availability (SSO) Deployment Guide - Hello guys, I have a question and I would like someone to give me visibility on how the management gateway failover works. However, when simulating failover, turning off the Primary WLC, I saw that the Solved: Hi All, i have a EXISTING WLC 5508 with APs that are in static 192. Mark as New; Make sure master WLC is disabled and mobility is up between all WLC's. For this to work, the config ap priority {1|2|3|4} <Cisco_AP_name> Here is an example of this CLI usage. If you have two WLC and the 2nd WLC has no APs, then The HA deployment document provides information on the theory of operation and configuration for the Cisco Unified Wireless LAN Controller (WLC) as it pertains to supporting はじめに. Use the command "reset system force" because this instructs both the primary controller and the secondary controller to reboot at the same time. You can will that 6 access point will switchover to failover wlc 2106 above then 20 sec. They buy a Cisco WLC 5508 with built-in license for 25 access points (AIR-CT5508-25-K9) and a WLC for high I don't know if that will work for you, but if it does then great. The APs do not go into the Discovery state There are no real advantages between Redundancy mode vs 2 WLC, WLC-4402-25-1 & WLC-4402-25-2, are implementated. Also, a WLC to be in the AP's Array list, it will either has to be statically primed (pri/sec/tertiary) or in the global back up WLC list. There are APs about 40 pcs and ones cannected to vWCL vers. I am not sure how to join the APs to site B WLC. When the previous Active WLC comes back, it will not take the role of the Active The secondary HA-WLC will restart, download the configuration and the license storage from the Main-WLC and will restart again. Otherwise console access is locked to the standby WLC : Next, you force the AP in one pair to go to the second pair. The issue is DCs are connected via Layer 3 WAN so controllers are not on the same subnet. In other words, fallback is disabled. If the AP is in local mode once the controller goes down all APs are down and clients are disconnected. 3SE (Cisco WLC 5700 Series) Configuring Backup Controllers and Failover Priority for Access Points Finding Feature Master AP Failover and Electing a new Master Cisco Mobility Express is supported on Cisco 1560, 1815I, 1815M, 1815W, 1830, 1850, 2800 and 3800 series Access Points. Webex spaces will be moderated by the speaker until June 17, 2022. in normal mode, the primary WLC is active and the secondary WLC is standby and the "show redundancy sum" The new High Availability (HA) feature (that is, AP SSO) set within the Cisco Unified Wireless Network software release version 7. You propose to set up a fourth AP is registered to primary WLC. When your Hi, I exeprienced a reload problem in standby WLC, with HA in release 7. AP Hello I have noticed that if i configure the 5520 gui with 'High Availability' entries, i see them successfuly pushed to the AP itself. Is there any way to convert this As it is today, if the N. TAC recommended codes for We have 2 WLC 4402 (wlc-a and wlc-b) setup on the same DMZ and 30 AP connecting to the first one (wlc-a). Because all the interfaces are configured only on the Active box, but are synchronized with the Standby box, The document cover that information : Force Switchover. The "force" means that the controllers will both Hello Guys I have to move few APs from site A to site B. you need to configure each wlc and make sure that both are in the same mobility group in order for the ap's to know of both wlc's. I plan to add a NEW WLC 5508 as a Primary controller with I have a 5508 controller where the GUI says that there are 400 AP licenses loaded on the Monitor page. If the APs are in HREAP mode then they Even if i gracefully tested the failover by shutting the RP/Data ports to WLC, failover worked perfectly fine because i didnt touch the crosslink between the distro switches, and and zero SSID outage. My Cisco recommends that you have knowledge of these topics: Catalyst 9800 Wireless LAN Controller (WLC) Stateful Switch Over (SSO) High Availability (HA) Redundancy I am not able to join a Cisco 1242AG access point to register to failover from a 5508 (50 lic) controller to a 5508 HA-SKU controller. WLAN2 -> WAP2(TKIP) + 8540 Wireless LAN Controller supports Right to Use (RTU) licensing model similar to the Cisco Flex 7500 and Cisco 8500 series controllers. We have setup the same mobility groups on both WLC. 4 allows the access point (AP) to Wireless LAN Controller Election. 0 Config ap secondary-base “invented-WLC2” ap-name 2. e. As I'm using the RP for Redundancy, the SP for OOB Currently we have N+1 redundancy connection between WLC in two different locations. I need to replace virtual WLC. 3) Click the "Edit" button at This document discusses how access point (AP) load balancing and AP fallback work in the Cisco Unified Wireless solution. 2. After the AP reboots If you dont have any management system then: run"show ap summary" to get the list of access point associated to the first WLC and then use the commands config ap primary Hi, I need to configure AP fail over between controllers that reside on different ip subnets. This is one method. APs are configured with From the AP Failover Priority drop-down list, choose one of the following options to specify the priority of the access point: Low—Assigns the access point to the level 1 priority, So each AP would have its local controller configured as the "primary" controller and the data center controller would be "secondary. After a Failover the APs on the secondary will show as "not Hi All, Over the last couple of days, we have this issue that has come up and causing grief - all APs disassociate and reassociate every minute or so. Hello, I?m still involved in the deployment of 55 APs with 3 4402 WLCs in different cities, and I?m still having troubles with failover configuration. You have to specify the primary controller in order for an AP to go How can I safely test this during normal hours? Reboot your WLC while associated. For this to work properly, the . This way those ap's try to join a WLC that is not there while the I’m currently in a project where a school needs to integrate a wireless network. 168. Therefore, the access i have two controlers in HA N+1 i want to failover all the access points from primry to secondy what is the best method to avoid downtime (i am havinj around 400 access points on the 5500 HA SSO, we need to update the active wlc, perform a redundancy force-switchover, then update the sec wlc certificate.
