I've a WLC2125 ( 2.2.193 ) that I often found with no traffic on ethernet port ( with no LAG ) .
After that I've to reboot the WLC to fix the situation.
The WLC is connected with just one port.
Any idea ?
Many thanks in advance
Sounds like you have a VLAN mismatch on the management interface.
many thanks for the reply.
The WLC sometime works fine for days and sometimes just for hours, so I think to exclude configuration issue.
I told that i connected just one port because on 2106 i found another issue when connecting more porte to carry different VLAN ( or interfaces ).
how many APs per port? max 6
do not use POE ports 7 & 8 for LAN connection, use ports 1 to 6
