How can I deactivate STP only on one port?

[Chris991]

Hello!

I have the CSE-H53 Serial-Ethernet-Converter from the company Sollae on a HP 4200vl (L11.20).

The device use port A20.

When I look in the switch log I see following entries:

I 08/21/12 09:37:20 ports: port A20 is Blocked by STP

I 08/21/12 09:37:21 ports: port A20 is now off-line

I 08/21/12 09:37:39 ports: port A20 is Blocked by STP

I 08/21/12 09:37:40 ports: port A20 is now off-line

I 08/21/12 09:39:01 ports: port A20 is Blocked by STP

I 08/21/12 09:39:01 ports: port A20 is now off-line

I 08/21/12 09:39:05 ports: port A20 is Blocked by STP

I 08/21/12 09:39:06 ports: port A20 is now off-line

After the block/offline action from the switch the device is permanent offline.

Is it possible to deactivate Spanning Tree for one Port?

The Spanning Tree config from the switch:

spanning-tree

spanning-tree config-name "sus"

spanning-tree config-revision 1

spanning-tree force-version RSTP-operation

[Richard Litchfield]

spanning-tree A20 bpdu-filter

This will "stop a specific port or ports from transmitting BPDUs, receiving BPDUs, and assume a continuous fowarding state" (on a 5400zl and other ProVision switches).

Be careful when playing with spanning tree though - you don't want to create a bigger problem!
