WCS 7.0.164.0 - WLCs unreachable

[alex.de.gracia]

Hi Guys,

For some reason overnight the WCS server can no longer reach the lan controllers.

They are on the same subnet and can ping both ways.

I tried deleting and re-adding but it still cannot find it.

I've tried rebooting everything and still doesnt work.

Anyone have ideas?

I upgraded the WLCs to the latest 7.0.98.218 to see if that was an issue. It was 7.0.98.0 previously. Doing this obviously made no difference.

I'll check SNMP but meanwhile which logfile do i check?

So it looks like i'll focus on SNMP?

Thanks Surendra.

It was SNMP.

Some reason SNMP config was lost in the WLCs and since the snmp string is starred out in WCS i had to create a new string.

Then i had to delete the controllers from WCS and rediscover them with the new snmp string.

All works now!

Thanks for pointing me in the right direction. I thought WCS only talks via SSH as its more secure.

Thanks again! I'll give you a star! :-)
