Symptom
have two controllers in HA (AP-SSO) try to configure IMM for active and standby. However only a single ip gets synced to both active and standby.
Conditions
HA AP SSO ( Active standby)
Workaround
-configure CICM imm when wlcs on stand alone not in HA
-use DHCP pool with only two IP address
-configure static arp
Further Problem Description
(5520-1) >imm address 10.10.10.x 255.255.255.0 10.10.10.x
(5520-1-Standby) > Does not allow any imm commands.
Force-switchover is performed. And upon issuing the following command on the active/secondary unit we see the following:
(5520-1) >imm summary
This will take some time...
Please be patient!
User ID.......................................... admin
DHCP............................................. Disabled
IP Address....................................... 10.10.10.x
Subnet Mask...................................... 255.255.255.0
Gateway.......................................... 10.10.10.x
looks like the imm configuration made on the active WLC is sync across the peer device( active /standby).
