Assigning an IP address to a fastethernet port on a NM-16EWS-1GIG card

[manuel.dennis]

I am trying to implement a 3845-SRST/K9 with a NM-16EWS-1GIG RJ-45 port card under IOS 12.4(24)T4.

When I attempt to assign an IP address to a fastethernet port I get a response that the card is L2.  Is this correct?  Is the card only L2 capable, or can I do something in the IOS, so that I can assign IP addresses to the ports?

Hi,

To assign an ip address to  this interface you must make it a routed port( by default it is a L2 port, remember this is a switching module) by issuing the interface command  no switchport then you can do ip address x.x.x.x

Alain,

Thanks.  It never occurred to me that a router would behave like an unmanaged switch.  I looked at the IOS 12 command reference and it shows the command implemented at the switch level.  On a router, do I implement it at the router level or the port level?

Hi,

The port is on the switch module but it configurable from router IOS and so you just type  int fx/x and under it no switchport

and then you can give it an ip address.

Alain,

Thanks,

I used the sequence:

config t

interface fastethernet1/n

no switchport

ip address nnn.nnn.nnn.nnn  255.255.255.n

and it worked, but I had to do it for each port, which was a pain.

Hi,

You could have done it with the interface range command.

Hi,
i think you can do no switchport on multiple interfaces with command interface range fa0/1-5.

Hello Manuel,

The NM-16EWS-1GIG card is Layer 2 (L2) and does not support assigning IP addresses directly to its ports. To use IP addresses, connect it to a router with Layer 3 capabilities.
