I have configured HSRP on the two RSP MgmtEth interfaces so I can manage the router from the same IP address regardless of the active RSP:
router hsrp
interface MgmtEth0/RSP0/CPU0/0
address-family ipv4
hsrp 1 version 1
timers 1 3
preempt
priority 105
address 10.0.0.1
!
interface MgmtEth0/RSP1/CPU0/0
address-family ipv4
hsrp 1 version 1
timers 1 3
address 10.0.0.1
!
When I do show hsrp commands the HSRP configuration seems to be working. The L2 switch connecting to these MgmtEth interfaces also see the MAC address on the correct interface. But ICMP/SSH are not working. The control-plane configuration is rather basic:
control-plane
management-plane
out-of-band
interface all
allow SSH
allow SNMP
allow TFTP
allow Telnet
!
Is it unsupported to run HSRP over MgmtEth interfaces or am I missing something?
