CatOS - setting portvlancost back to default

mmedwid · ‎09-26-2007

I inherited these switches with portvlancosts specified. I would like to

set spantree portvlancost 5/1 cost 3099

I would like to set these to the default 19 - easy enough. But I also don't want this line to appear in the config any more like it does you fire up a new catos switch.

I tried

"clear spantree portvlancost 5/1 cost"

but that's giving me

"Usage: clear spantree portvlancost <mod/port> <preferred_vlans>

(preferred_vlans = 1..1005,1025..4094)"

Anyone got the secret?

If 5/1 belongs to VLAN 10,

then issue the command :

clear spantree portvlancost 5/1 10

Hope this helps.

Thanks for the reply and idea to try. But the line is still in the config. Hmm.

Note from config:

set spantree portvlancost 2/7 cost 19

set vlan 300 2/2-48

So the cost is 19 and the port 2/7 in this instance is on vlan 300.

I run:

c4006-1> (enable) clear spantree portvlancost 2/7 300

Port 2/7 VLAN 1-1005,1025-4094 have path cost 19.

But alas show config shows the line is still there.

sho config

(blah blah..)

set spantree portvlancost 2/7 cost 19

Did you try entering it without the "cost" statement at the end , that may default it .

"clear spantree portvlancost 5/1

Leaving off cost catos prompts me for preferred vlans..

c4006-1> (enable) clear spantree portvlancost 2/7

Usage: clear spantree portvlancost

(preferred_vlans = 1..1005,1025..4094)

can you try saving your running-config to startup ?

mmedwid · ‎09-26-2007

This is catos. No copy run start here.

If you take a brand new switch and do show config all, what do the portvlancost look like?

If you run set spantree uplinkfast disable on a switch, the UplinkFast feature is disabled, but the switch priority and port cost values are not reset to the factory defaults. To reset the values to the factory defaults, enter the clear spantree uplinkfast command.
