A9K-24X10GE-1G-TR - how to set interface speed?!?

Anyone know how to set IFE port-group to 1G on a A9K-24X10GE-1G-TR ?

 

Seeing this  module's ports are configured in IFE port-groups

(https://www.ciscolive.com/c/dam/r/ciscolive/emea/docs/2018/pdf/BRKARC-2003.pdf)

 

After significant searching I can't find any reference in how setting a port-group to 1G is actually done.

I see no 'speed' command available on the IFE port-group port1.

I'm running 6.5.3-64.

 

A9K-48x10-1G Port Speed Rules
• Interface Port Speed is configurable: 1G / 10G
• Per default, all ports are 10G
• The 4 Rules:
1. All ports in a port-group (group of four ports) have to have the same speed.
2. If the first port-group on an IFE (group of three port-groups) is configured for 1G, then all ports
in that same IFE must be 1G.
3. If the first port-group of an IFE is 10G, then the other two port-groups in that same IFE can be
any combination of 1G or 10G.
4. When configuring port speeds, all ports of a given linecard need to be configured together in
one single CLI command.
• Deviations from these rules will results in a CLI rejection
• Changing port speed on an interface does not impact traffic on other interfaces

 

TIA,

Re: A9K-24X10GE-1G-TR - how to set interface speed?!?

Some good information about these cards from CiscoLive Las Vegas 2017 BRKARC-2003 for a 48x10GE-1G-TR.  The configuration for the 24 port variant is the same. 

 

hw-module location <rack>/<slot>/CPU0 port-mode RxS,RxS[,RxS…]

R = = Run-length (number of consecutive ports with same speed)

S = Speed (1 or 10, in Gbps)

 

Example:

 hw-module location 0/4/CPU0 port-mode 8x10,4x1,4x10,8x1,20x10,4x1

 

Here is the presentation with the information.  The information above is on slide 25.

Thanks for the response!

ahh - that page was removed for the same 2018 document.

I could find no config reference to doing this on CCO anywhere - odd for a module that came out in 2017(?).

 

I like CLI as much as just about everyone, but yuck.

Also it doesn't act this way in at least 6.5.3.

Maybe that's why 2018 document removed that page - perhaps they've changed it?

:-(    there's no "port-mode" subcommand (and it's not hidden there).

Try it from config and not admin and you should have the option.

gawd -  yes, mystery solved. Thanks Patrick.

 

not 'hw-module...' from Exec or adminExec but within config.

I've been more used to using that command at the exec level and never had need for it from within the config.

I'll grumble that use of a command in different ways at different levels seems poor form.

 

Once committed, the interface designation changes to reflect [Gi|Te] and the interface order changes with GI's listed before TEs - another potential place for some confusion. Personally prefer to see it left in port order using "show int" or "sh controller.." to indicate the speed it's running at.  Where's port 20? oh, there it is above port 0.  If only I were Chuck Robbins ;-)

Hi, What about the license? can share the show platform and show license.

config t
