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:

Any ideas?? Could be due old firmware?

Thanks in advance!!

  • As far as I know, all you need to do is to use 1 Gb optics instead of 10 Gb optics. The interfaces will still be called TenGigabit rather than Gigabit. We use a lot of 4507R+E with Supervisor 7, and we just use the proper optics for the situation, but do not use any different configuration commands (other than QoS). – Ron Maupin Nov 18 '16 at 20:42
  • But now, the half of 1Gbit optics remain inactive, and on the other hand, i cannot force TenGigabit interfaces, work at 1000 Mbps full duplex. – xavidpr4 Nov 20 '16 at 14:51

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).

But now, the half of 1Gbit optics remain inactive, and on the other hand, i cannot force TenGigabit interfaces, work at 1000 Mbps full duplex.

Based on you comment, I think I see what you mean. You can have a total of four supervisor interfaces. With a single supervisor card, those are all on the single card, but with dual supervisor cards, you split the total of four active interfaces between the two supervisor cards: the first two interfaces on each card are active, but the last two interfaces on each card are inactive.

This is because a supervisor card can only handle four interfaces, and only one supervisor at a time is active. It doesn't matter if the interfaces are used as SFP (1 Gbps) or SFP+ (10 Gbps); that is just the way it is. The idea is that you use the four interfaces as uplinks, and when you have dual supervisors, you want the uplinks split between the cards for failover.
