As described in the article below
"When Stateful Switch Over is enabled, there is no SNMP/GUI access on the service port for both the WLCs in the HA setup."
So my question is how do you monitor the health of your backup unit in the HA cluster? How do you confirm that power-supply, fans etc are all functioning in case of SSO fail-over?
It certainly seems like quite the shortcoming and for larger service providers (such as us) this is a real pain.
Even the WebUI is knackered (CSCue50988)
