Spanguard not working

Spanguard not working

Hi,
We are using Extreme and Enterasys product in my foundation.
Even though I configured spanguard on Enterasys B5 and B3, Spanguard didn't work.
I configured span guard on my switch as follows:

set spantree adminedge ge.1.1-23 true
set spantree spanguardtrapenable enable
set spantree spanguard enable

I'm waiting for your help.
Thanks.

Remote Switch is unmanagement(TP-Link SL1226). I don't know whether STP is enable or disable on remote switch.
Remote switch connect to ge.1.1 on Enterasys B5.
ge.1.24 is UpLink on Enterasys B5

Enterasys B5G124-24
Firmware 06.81.02.0007
Remote Switch TP-SL1226(unmanagement)
Configuration file (Enterasys B5)

Configuration All

^This is likely you're issue. Jeronimo beat me to it. What model switch are you plugging into ports 1-23 that isn't being blocked? Best of luck.

You're still not clear! Is STP enabled on the remote switch on the port that you connect to the local switch that has Spanguard enabled? If STP is not enabled remotely, that is, not sending BPDUs, Spanguard will not lock the port.

Yes, RSTP and Spanguard enabled.

So you are connecting another switch with STP enabled to a SpanGuard-enabled port and the port does NOT lock?
