Cisco 1941 Router – Configuring an EH-WIC Card

ciscocisco-iosrouter

I have a Cisco 1941 Router that has just two ports for Gigabit connection but wanted more so I got a four port Cisco EH-WIC Card and connected it to it.

I have been trying to assign IP address to the port GigabitEtnernet 0/0/0 because I have a cable already connected to it whose device I want it facing the router directly because I dont want to NAT its address. I want to assign the physical address on the port.

Kinldy help if you understand what I am saying.

That card doesn't provide routed IP interfaces - it is a switch. You can assign IPs to specific physical interfaces of this card by assigning the port to VLAN, and then defining IPs on the VLAN interface (also called SVI - Switched Virtual Interface).

Here's list of what you can do on normal, routed interfaces and on SVIs: http://www.cisco.com/c/en/us/products/collateral/routers/1800-series-integrated-services-routers-isr/prod_white_paper0900aecd8064c9f4.html

So you need to do something like that (assuming GE0/0/0 is the first port of the switch card):

int ge0/0/0
 switchport mode access
 switchport access vlan 100
 no shut

interface vlan 100
 ip address 1.2.3.254 255.255.255.0
 no shut
