catalyst 3548 no spantree command

[rkbhatt]

i would like to remove the command from my switch config.

no spanning-tree vlan 173

no spanning-tree vlan 204

what is the command for this.

please guide,

[lgijssel]

The default is spanning-tree enabled.

The command: spanning-tree vlan 173 will restore the default.

Simply do:

conf t

spanning-tree vlan 173

spanning-tree vlan 204

exit

Regards,

Milan

The XLs support 64 spanning-tree instances. If you have spanning tree running on more than 64 VLANs, you will see this for the remaining of the VLANs. How many VLANs do you have in your network?

Well, you need to decrease the number of VLANs on particular switches.

Use

config-if)#switchport trunk allowed vlan remove

command or

(config-if)#switchport trunk pruning vlan add

command (I suppose you are using VTP) on your trunks.
