STP EtherChannel – All modes DEEP DIVE, cross-stack EtherChannel / channel-protocol reviewed, and verification cmds demonstrated!

I've removed the 2 x 1Gig links and replaced them with 3 FastEthernet links for this lab, as I wanted to do some adjusting of speed and duplex throughout the lab, but with multi-mode fiber it is not having any of those sort of changes: SW2(config)#int gi1/0/1 SW2(config-if)#speed ? nonegotiate Do not negotiate speed SW2(config-if)#duplex … Continue reading STP EtherChannel – All modes DEEP DIVE, cross-stack EtherChannel / channel-protocol reviewed, and verification cmds demonstrated!

STP EtherChannel – Fundamentals illustrated, “On” mode basic config, troubleshooting, and verification on lab!

During the lab I will only use the FastEthernet interfaces between SW1 and SW3 to demonstrate EtherChannel "On" configurations and behaviors, as I have found Multi-Mode Fiber interfaces do not interact the same way, as shown at the bottom of post!   STP EtherChannel Fundamentals   STP EtherChannel is the answer to STP's Loop Prevention … Continue reading STP EtherChannel – Fundamentals illustrated, “On” mode basic config, troubleshooting, and verification on lab!
