Hi all,
How should the "spanning-tree portfast" command be configured on an Port-Channel interface ?
Should it be configured
1) On the Port-Channel interface itself (only)
2) On every interface which is member of that etherchannel but not on the Port-Channel interface
3) On the Port-Channel interface and on every interface which is member of that etherchannel
When you configure "spanning-tree portfast" on the Port-Channel interface, that command is not replicated on the member ports.
I know that the switch only sends BPDUs to one interface of the etherchannel (the first one active) but don't know how the portfast works in this scenario.
Thanks !
Sam
