We have a Catalyst 4006 with a four blades:

1 is a WS-X4232-L3 (the second mod) with 2 gigabits and 34 ethernet ports.

3 are WS-X4148-RJ each with 48 ethernet ports.

The service module has two gigabit ethernet slots with the first being populated and the fiber goes back to our main building also hosting a 4096 switch.

Here is our problem:

With the gbic plugged into 1/1, the last third of all the ports on the blades do not work. That's ports 19-34 on mod 2 and ports 34-48 on mod 3, 4, 5. Switching the gbic to 1/2 produces the revers. The first two third of the ports on the blades do not work, but the last third do.

No matter which port the gbic is in, I can ping any workstation ip on any port form the service mod (consoled in through the management port). But, if the workstation is in one of the dead ports, it cannot ping the service module, gateway, or anything for that matter.

Any ideas on where to start looking?

You need at least 5.1 for the WS-X4232-L3 ...


"You can group the two internal Gigabit Ethernet interfaces into two trunks, a single Gigabit EtherChannel, or configure them as independent interfaces (links). If trunked or channeled, the internal Gigabit Ethernet channel supports trunking using the IEEE 802.1Q protocol. You also can configure each Gigabit Ethernet interface (link) independently as a separate VLAN trunk or nontrunked routed interface. "

If you set up the gig ports to split the backplane, it might explain this. If you plug in TWO GBICs, do all the ports come up?

Can you supply a printout of the RSM with a show ver and sho config?

The only change to the network was the replacement of Mac 5200 series computers with Dell 110 Optiplex's.

It looks like there are issues with the pipe between S2 and S3.

I'll look into the link you supplied.
