Does anyone know the difference in using set spantree portcost vs set spantree channelcost??
I am converting my Data Center LAN from spanning-tree PVST+ to Rapid STP. When removing uplinkfast during this change, all of my Access Layer Switch uplinks (channeled) will default to the original bandwidth determined portcosts. I'd like to keep my blocked ports down at the Access Layer Switches and was trying to see the differences between these 2 commands. What is the difference outside of the obvious, one is used on ports and the other is used on channels??
When I enter set spantree channel cost, the console displays this:
gv2d-D1> (enable) set spantree channelcost 1666 25
Port(s) 5/1-8 port path cost are updated to 40.
Channel 1666 cost is set to 25.
Warning: channel cost may not be applicable if channel is broken.
If I loose my channel could this be a problem??
Thanks for your help,
I'm pretty confident that's the case;-)
I could found this in the CatOS configuration guide:
