Re: 2950 switch

Hello Anita,

>> "If the STP is enabled, this feature should be enabled

as I told in my first post leave it exactly as you see

no spanning-tree ...

I think in this way the switch behaves normally by automatically relying BPDUs received on its root port out of all of its ports in forwarding state.(vlan specific)

the command is present in some command references of higher models like c6500.

I agree that is not well documented

Hope to help

Giuseppe

Re: 2950 switch

Hello Anita,

this is a default and you should be fine without enabling it.

When enabled the command changes the way the switch treats the BPDUs regarding their propagation: the switch to optimize BPDU transmission can do something different from normal relay behaviour.

I didn't find it in command reference

I also cannot find it from cisco web site, it seems that it is undocument.

"If the STP is enabled, this feature should be enabled". Above statement is correct or not?
