Hello Friends, i hope you all are very well.
I´m having troubles with the RMI+RP configuration on a C9800-L-C-K9 cluster, configured the following parameters:
CHASSIS_HA_LOCAL_IP = 169.254.119.205
CHASSIS_HA_REMOTE_IP = 169.254.119.206
CHASSIS_HA_LOCAL_MASK = 255.255.255.0
RMI_INTERFACE_NAME = Vlan302
RMI_CHASSIS_LOCAL_IP = 10.220.119.205
RMI_CHASSIS_REMOTE_IP = 10.220.119.206
WLC01#show redundancy states
my state = 13 -ACTIVE
peer state = 8 -STANDBY HOT
Mode = Duplex
Unit = Primary
Unit ID = 1
Redundancy Mode (Operational) = sso
Redundancy Mode (Configured) = sso
Redundancy State = sso
Maintenance Mode = Disabled
Manual Swact = enabled
Communications = Up
client count = 149
client_notification_TMR = 30000 milliseconds
RF debug mask = 0x0
Gateway Monitoring = Enabled
Gateway monitoring interval = 6 secs
The devices are connected via PortChannel to a C3560G, Active WLC (Two0/0/1-2 -> Gi0/3 - 4 **PortChannel 1) and StandBy (Two0/0/1-2 -> Gi0/5 - 6 **PortChannel 2) for a HA test. The main problem comes when i perform a shutdown on the Po1, its expected that due to lost of connectivity to the default gateway (which is configured on the test switch, i will add some data in the next section) the WLC would perform a switchover to maintain connectivity to the DG, but is not happening:

Once that the Po1 is down, the WLC logs the link faiulre and the RMI link down is received but there is no switchover to the standby WLC

Is this the expected behaviour under this scenario? probably i would need another switch to try a HSRP environment.
by the way, this is the IOS version:

I will appreciate very much any help with this issue.
Thank you all.
