I'm not sure whether the 4-port behaves in the same way as the 16-port, but on the 16-port version you assign the switchports to a VLAN, then you create an SVI interface to represent the VLAN at layer-3, and then put the IP address on that.

These are layer2 ports but you can create a Vlan, assign a Vlan membership to those ports and create a Switch Virtual interface.

For instance:

1) Create Vlan

vlan database

vlan 2 name Vlan2

exit

2) Assign membership

interface f0/1

sw mode access

sw access vlan 2

3) Create SVI

interface vlan 2

ip address x.x.x.x x.x.x.x

Re: 4 Port Switch module on Router

Does entering "no switchport" before you do ip address etc... work? It works in dynamips :-)

Re: 4 Port Switch module on Router

As far as I know, the 16-port NM supports layer-3 ports, but the 4-port WIC does not. Can anyone confirm that? Does the dynamips support it on both modules?

If the dynamips supports it but the real one doesn't that is very very interesting.

Re: 4 Port Switch module on Router

The 'no switchport' command works but you can't make that port a routed port.

Verification:

interface FastEthernet1/1

description To R1 F0/0

no switchport

ip address 192.168.1.7 255.255.255.0

interface FastEthernet0/0

ip address 192.168.1.1 255.255.255.0

duplex auto

speed auto

Rack1SW1#ping 192.168.1.1

*Mar 1 00:16:27.987: IP: tableid=0, s=192.168.1.7 (local), d=192.168.1.1 (FastEthernet1/1), routed via RIB

*Mar 1 00:16:27.991: IP: s=192.168.1.7 (local), d=192.168.1.1 (FastEthernet1/1), len 100, sending

*Mar 1 00:16:27.995: IP: s=192.168.1.7 (local), d=192.168.1.1 (FastEthernet1/1), len 100, encapsulation failed.

Success rate is 0 percent (0/5)

In short, it does not work :)

Re: 4 Port Switch module on Router

Is that dynamips or the real thing?

dynamips.

Also tried on the real thing, same result.

It's a layer2 port.
