Hi all,
After having some troubles with VSL, I finally had to convert one 6509-E chassis back to a standalone chassis. Now I would like to bring it back into the VSS configration.
Whenever I try to convert it to a virtual system (switch convert mode virtual) I get the msg %Please configure local switch number first". After doing so by entering "switch set switch_num 1 local" I still get the same msg.
Has anyone faced the same situation before ?
Any hints or tipps are very much appreciated.
Thanks and best regards
Roman

VSS configuration should be like so..
6500-1
conf t
switch virtual domain 100
switch 1
switch 1 priority 100
switch 2 priority 110
exit
6500-2
conf t
switch virtual domain 100
switch 2
switch 2 priority 110
switch 1 priority 100
exit
Not sure where the switch set switch_num bits come from?
Hope this helps

hi graham,
unfortunately this is exactly the config i've done. when i try to configure po 1 as vsl-link (switch virtual link 1) i get the same msg "%please configure local switch number first".

Hi Graham, i finally solved the problem, which indeed was a strange behaviour. First I checked the switch_id in rommon with the command "switch read switch_num local" - the number was correct configured as "1".
I changed this value to "2", which is basically wrong, since the other VSS component already is configured with the same switch number.
After that, I was able to configure Po 1 as VSL channel. Then I changed the switch number back to "1" and finally was able to do the "switch convert mode virtual" and here we go.
Many thanks for replying to my post.
Best regards

Wow madness.
VSS can be a touchy bit of tech.
Ive spent many hours in boot-loops and rommon before finally getting a working solution.
But glad its working It really is lovely when working correctly!

Yes, so did I and indeed I like VSS since it came out first and it works just great

Actually this is a possible the explanation:
Once you have assigned the switch number just exit, DO NOT ASSIGN SWITCH PRIORITY YET! If you assign switch priority after assigning the number you will encounter virtual switch link configuration problem that looks like this %Please configure local switch number first
under the port-channel interface.

Very Basic Configuration :: This should work as expected.
VSS(config)#switch virtual domain 100
VSS(config-vs-domain)#switch 1
VSS(config-vs-domain)# exit
VSS(config)#interface port-channel 1
VSS(config-if)#switch virtual link 1
VSS(config-if)#interface TenG 5/4
VSS(config-if)#channel-group 1 mode on
VSS(config-if)#interface TenG 5/5
VSS(config-if)#channel-group 1 mode on
VSS(config-if)#end
VSS#switch set switch_num 1 local
VSS#switch convert mode virtual
