Solved: Etherchannel and STP - Cisco Community
Recently there was a debate among some folks about how STP is handled within an Etherchannel. I understand that once an Etherchannel is defined, regardless of PAGP or LACP, that the new port-channel is introduced into the spanning tree and the physical ports are removed. That makes sense. The questi...

Solved: STP: Root port vs. designated port - Cisco Community
2010年12月7日 · The one that is connected on the side where the STP root resides is called 'root port'. A port not facing the root but forwarding traffic (while lowest cost) from another segment is called 'designated port'. Another difference is a designated port is transmitting bpdu's on the segment while a root port only listens to bpdu's from the root ...
