CSCvg48576 - Cisco IOS and IOS XE Software Cluster Management Protocol Denial of Service Vulnerability

[Christian Jorge]

Good morning

Is there any impact disabling this feature ("no cluster run") on a switch in production?
I don't remember using this kind of cluster feature.

Regards

do you have any cluster configured in the network ?

worth checking before removing this.

show cluster candidates

show cluster members

if nothing is configured, then you are good.

I don't believe anyone uses this feature because it is very archaic.
And if it is in use, then it should be disabled.
