How many EoIP tunnels at the same time? (One Anchor <--> HA Pair )

[cedar_lee]

Hi Experts,

With AP SSO, there should be two CAPWAP tunnels between an AP and the HA controller pair at the same time. Is it correct?

Then how many EoIP tunnels between the internet anchor controller and the foreign controller HA pair at the same time?

Thanks

Hi Cedar,

in AP SSO, only single CAPWAP tunnel maintan at a time & see the below reference for details.

There is only one CAPWAP tunnel maintained at a time between the APs and the WLC that is in an Active state. The overall goal for the addition of AP SSO support to the Cisco Unified Wireless LAN was to reduce major downtime in wireless networks due to failure conditions that may occur due to box failover or network failover.
This allows the access point (AP) to establish a CAPWAP tunnel with the Active WLC and share a mirror copy of the AP database with the Standby WLC. The APs do not go into the Discovery state when the Active WLC fails and the Standby WLC takes over the network as the Active WLC.

in the same sense, EoIP tunnel limitation will be 71 for a anchor controller. See below

Hi Rasika,

Thanks for the reply.

So, no matter CAPWAP or EoIP tunnel, only the active WLC maintains the tunnel.

Yes, it is.
