vss - can i remove the preempt command safely ?

[carl_townshend]

Hi all

After some recommendations, it has come to light that I need to turn off VSS preempt as I dont want any downtime

On my primary switch can I turn off preempt without disrupting anything? as its a live network

are the commands

switch virtual domain 100

no switch 1 preempt

please can someone let me know asap,

Yes you can remove without any issues.

this is been recorded under below link:

When removing the preempt commands in Catalyst 6500 Series Switches in VSS Mode, will it reload the switches?

The switch preemption is not recommended. Therefore, removing the commands is a good practice and does not cause a reload. For more information on the Preemption feature on VSS, refer to Switch Preemption.

Carl,

Ys the syntax is correct.

To disable preemption you need to issue the following command:
no switch [1 | 2] preempt
