Cisco – Want to disable TenGbE to enable 1GbE Gbics in Cisco 4500

ciscocisco-4500

This is my first post into Cisco Forum, however I'm used to check it for every question or problem I have.

I'm putting back in production a Cisco 4507R-E switch with two supervisors, and what I need si to enable all SFP ports of 1Gbit by giving up the four ten gigabit ports, which I don't need anymore for the new purpose.

I've read that to accomplish that i need to issue the next command on the global config

hw-module uplink select gigabitethernet

But the switch do no recognise the command:

MAT_SW1_PT2(config)#hw-module ?
  module  Specify a linecard slot for the hw-module command
  slot    Specify a linecard slot for the hw-module command

MAT_SW1_PT2(config)#hw-module

Here is my running-config:

MAT_SW1_PT2#sh module
Chassis Type : WS-C4507R-E

Power consumed by backplane : 40 Watts

Any ideas?? Could be due old firmware?

Thanks in advance!!

When using the Sup II+10GE in redundant mode, you only have the first half of the ports on each supervisor. You can find that in the documentation from Cisco:

When you select TenGigabit Ethernet uplinks on WS-X4516-10GE and WS-X4013+10GE Supervisor Engines in RPR or SSO mode, only TenGigabitEthernet 1/1 and 2/1 interfaces are available. Similarly, when you select Gigabit Ethernet uplinks, only GigabitEthernet 1/3, 1/4, 2/3, and 2/4 interfaces are available. When you select to use both uplinks concurrently, TenGigabitEthernet 1/1 and 2/1 interfaces and GigabitEthernet 1/3, 1/4, 2/3, and 2/4 interfaces are available.

You will not be able to use all 8 Gigabit ports with these supervisors. You would need to upgrade to a newer supervisor to make use of 8 Gigabit ports, such as the Supervisor 6-E/6L-E (with the TwinGig modules).

Keep in mind that your older WS-X4548-GB-RJ45V linecards will potentially have performance issues as they are limited to 6 Gbps throughput. Upgrading to a newer supervisor won't change that restriction, but it will increase the capabilities of your WS-X4548-GB-RJ45V linecards to some degree as well (4 queues to 8 queues, IPv6 support, etc).
