No https access to standby WLC 3504 in HA

[pfaiscacisco]

Hi,

I can't get http/https/ssh sessions to standby WLC 3504 when primary is off, version 8.10.185, all clients communications work well...

The WLC respond to pings

Is it normal or is there any configuration to solve this?

Thank you

Cheers

Hi,

first I think SSO not work with this config 
second 
try using .14 instead of .15

Hi,

Not work?  Why?

"Like on other WLC, WLC 3504 supports both AP SSO and Client SSO"

How do you access the WLC for management? If it is via service port, make sure both service ports are connected to the correct switch and switchports are configured correctly. (switchport mode, vlan etc.)

If you are access it via the data ports or management VLAN, as @Flavio Miranda  mentioned compare the switchport configuration form the switches where the WLCs are connected.

Hi,

Via management vlan ..

The settings on the switch are the same on all ports:

-----------------------

switchport trunk allowed vlan 3,4,10
switchport mode trunk

----------------------

Thanks

I am assuming you are using the same IP as primary to access, once HA is formed, the HA controller IP is overwritten by Primary, so if primary fails, the IP of primary should still be used for accessing HA controller.

If Yes then clear arp cache, browser history, try again, else try console and verify config as Flavio recommended.

Thanks,

We've done all that

WLC responds to pings

I forced by console the configuration of the access to http/https

We looked at the firewall and only no response from wlc, timeout

 can try reload standby wlc.  It recovered after reload.    ssh  could work.(http can't access,but telnet 443 it's ok)

 It is easy to appear after doing HA failover

As far as I know https will only work on the active WLC.
