UPGRADING TO INTERFACE 10G FROM 1G PORTCHANNEL WITH SUBINTERFACE

[Fidel Ernesto Gonzalez Baez]

Hi,

I have a dude, we are planing to upgrade from 1G interface to 10G interface.

actually, we have two portchannel  with  four interface each one, they are to 1G.

I want  replace the interfaces from the port-channel, with 10G interface but this portchannel have a lot of sub-interface.

if I try to remove the last 1G intefaces from the portchannel, it show a message, saying that the portchannel can not be without interface because have sub-interface, at least one interface must be in the portchannel.

i want remove all 1G interfaces and add the 10G interfaces.

i want to try this, If befere remove the last 1G interface, I add a 10G interface and later remove the last 1G interface, here is my question, this could works?

I would like to know a way to do this change.

somebody can help please..

That can't work as all links in a channel have to be of the same speed. You probably have to build a new channel for the 10Gig-links first, take that in service and then remove the old channel.

are you sure?

I have 200 sub-interface associated to that Portchannel and firewall rules, i cant delete the port-channel, must be another away.

I just want join the 1G interface and 10G interface for make the changed of interface. i going to do this in a maintance window.

another person can give me a diferent idea.

You could manually edit the interfaces in the startup-config and then reboot the firewall.

I made a test and worked.

Hi, 

How did you do that, have you deleted the portchannel and corresponding configurations such as ACLs and rebuild the same?

Your reply is awaited.
