4 port Switch module

I have a 1720 router with a 4 port Ethernet switch in one of the modules and the router does not recognize it. The LED for the module comes on and states WIC 1 OK, but the router does not recognize it. I upgraded the IOS on it to the latest. Doesn't this router support this card?

Re: 4 port Switch module

Are you trying to address the individual ports as separate interfaces, or addressing all four as a group (i.e., VLAN 1)?

As long as you're addressing the group as a single routed entity, then it sounds like a dead port.

I'm pretty sure you cannot address the individual ports as four seperately routed interfaces.

Good Luck

Re: 4 port Switch module

I am supposed to be able to see them as separate interfaces, i.e.

interface FastEthernet1

switchport access vlan 2

!

interface FastEthernet2

!

interface FastEthernet3

!

interface FastEthernet4

I would then create a VLAN as in this config and assign it an IP.

My whole purpose in doing this is I have a DSL line to backup the Internet T1.

I have another router that I have the same card and the router identified the interfaces just fine, this does not for some reason.

See below what the SH TECH shows.

Re: 4 port Switch module

What code are you running? Looking at the data sheet:

http://www.cisco.com/en/US/products/hw/routers/ps221/products_data_sheet09186a00801c749d.html

I see that it needs either 12.3XC code, or 12.4T.

Re: 4 port Switch module

12.3(19), shouldn't that work? Or it must be of the C type or 12.4?

Re: 4 port Switch module

Nope, 12.3(19) is mainline and according to the IOS map, it does not look like it branched off that XC train. You either need a 12.4T or a 12.3(2)XC or later in the same train.
