How can I specify my etherchannel name when creating an etherchannel

boyd98 · 11-09-2009, 08:40 AM

I have an existing etherchannel that is made up of two physical adapters. I need to change the speed on the adapters from 100M to 1gb.

The only way i know how is to break the etherchannel, and then change the speed on the idvidual adapters. This requires rebuilding the etherchannel.

When I rebuild the etherchannel name I need to make sure it gets rebuilt with the same interface name it currently has - en13; as it is compiled and used for CRS.

When i have done this before, as the etherchannel rebuilds it will take the first free adapter name, which i believe is en9. Do i have to ghost the adapters somehow in the ODM -

Any help is greatly appreciated as it would alleviate some critical downtime -

Thx,

Boyd

Not sure if there is a straight answer on the above, but i ghosted some definitions in the ODM as a workaround

Hmm, ODM hack is one way....

You can add dummy adapters with smitty vlan to add vlan adapters to any exisiting adapter, even one of an underlying etherchannel adapter, and this will use up ent9 to ent12 for you, then create your etherchannel, then remove the vlan adapters if you like with smit or rmdev -Rdl ent9 to 12.

Just another option that is more under the control of smit / normal rmdev command than at risk of a typo when hacking the ODM - your choice.
