Any body can tell me how we can utilize the next NIC card on MCS servers.
Because I have on each server two NIC cards and I need to connect each card to switch, is that possible?
Assuming that you are running a Linux based product (CUCM 5/6/7, Unity Connection etc.) you need to go to the server console and issue the following command.
set network failover enable
This will set the second NIC to operate in standby mode - if the first NIC is disconnected the server will use the second NIC to communicate. Note only one IP address is used - it is not possible to have separate IPs on different interfaces.
Use show network failover to verify operation.
The NICs can be connected to separate switches as long as the switch ports are in the same VLAN/subnet.
Please rate if helpful.
