Every so often my WLSM will show that the link to the WLSE is down, although both the WLSM and the WLSE still show a status of "Security Keys Setup". I can't find any other evidence of network connectivity issues between the devices and even after I verify by pinging each device from the other the link-down status on the WLSM doesn't clear.
This doesn't appear to have any effect on clients as I have sometimes failed to notice it for several days. I've found that rebooting the WLSE will re-establish the connection, but surely there's a better way.
On the WLSE everything looks good:
Status: Active
WLSE to WDS Authentication Status: KeysSetUpWithWDS
On the WLSM the status looks good:
mhc-wlsm#show wlccp wnm status
WNM IP Address : 10.103.216.9 Status : SECURITY KEYS SETUP
But the WLCCP Network Management shows the link is down:
mhc-wlsm#show wlccp wds nm
WLCCP-NM : running, Configuration Parameter : 0x1

The last entry in the WLSM log also shows the link being down:
Jul 4 17:53:28: %WLCCP_NM-3-WNM_LINK_DOWN: Link to WNM is down
Any ideas what might cause this? Or what can resolve it short of rebooting the WLSE?
Thanks,
Paul
