How to deploy 1 gigabit in Catalyst 4500X

[Jackie Emmanuel Gabriel]

Hi All,

I hope you can help me, im currenly configuring a 4500X with 16 port. All sfp are 1Gig, but when I input show ip int brief, it shows that the interfaces are on 10 Gig. Does Catalyst 4500X already support the 1Gig SFP without inputting a command or do I have to configure it to activate the 1Gig interface?

Thanks,

Jackie Gabriel

Hi,

The switch should just recognise the port is using a 1GE SFP and run at the appropriate speed. The following is from my switch running IOS-XE 03.03.02.

As you'll see the show ip interface brief still names the interfaces as TenGigabitEthernetX/Y, but the SFP in Te1/9 is recognised as a GE SFP and operates at that speed. Also from the show run int te1/9 you can see there are no specific commands added for speed.

ocs4516x-1#sh ip int brie

Interface              IP-Address      OK? Method Status                Protocol

FastEthernet1          unassigned      YES unset  down                  down

TenGigabitEthernet1/1  192.168.71.2    YES manual up                    up

Steve,

Thanks for the info!

Wow, you have to do a "sh int tex/x" to see a 1Gig SFP?

Who came up with this type of design?

Hi Steve,

Thank you for your explanation. It really helped me a lot. But I hope the developers of 4500-X will also change the the show ip int brief display with respect to the SFP since the port is auto-detect. Just to avoid confusion.

I agree.  The port will determine the type of SFP you use.

Hi Jackie,

I am not sure if this is what you are looking for:

Try this out:

4506-E(config)#hw-module module 1 port-group 2 select ?
 gigabitethernet     Select this port-group's gigabit interfaces
 tengigabitethernet  Select this port-group's 10G interfaces

(Eg: 4506-E(config) #hw-module module 1 port-group 1/2 select gigabitethernet )

So after entering this command you will have all the ports trun into gig bit rather than 10 gig.

HTH

Inayath.

Hi Inayath,

I tried that command but it is not supported on 4500-X.

Thanks.
