We have 2 CPU's on our passport 8310 switch.
1st management port IP address is 192.168.2.1/255.255.252.0
This IP is in the same subnet as one of our internal VLANs.
2nd Management port IP address is 10.10.10.8/255.255.240.0
After reading the documentation on the switch, it was recommended that the management port IP address should not participate in the general routing of the internal network. Therefore I changed the IP address on the 1st Management port to 10.10.10.7/255.255.240.0 (so that both management ports are in the same subnet and they remain isolated from our main network)
After doing the above, the switch asked for a reboot in order to save the changes. I restarted the switch and the whole office had no IP addresses on their computers.
WHY SHOULD THIS HAPPEN
