Hello Team,

Will ISSU support on DNAC Version 2.3.3.7-72328-HF5.

We tried to upgrade 9407R switches with ISSU its successful. But some switches not successful.

I see some cisco documents stating that ISSU not supported on DNAC version  2.3.3.7-72328-HF5

I have tried Cat 9500 with SVL deployment and Cat 9800 WLC - issu works for me.

as long as device matrix works that should works.

But some switches not successful.

It seems that is not supported as per Docs.

[PrabakaranBalasubramanian16319]

Yes, As per document its not supported.
we tried to upgrade C9407 from 17.6.5 to 17.9.4a.  we got below error.

Activation got failed
ISSU Status : Failed, Current State : Aborted.
Reason : Mismatched Command List detected, remove these unsupported configuration from the system and reattempt upgrade procedure.
List the MCL using show redundancy config-sync failures historic mcl

After checking the logs.

SWITCH#show redundancy config-sync failures historic mcl

interface L2LISP0

!
interface L2LISP0
mtu 17892

end

Here am not able to remove mtu command ..Any suggestion to resolve this issue

the error complaining about the config - to proceed you need to remove that line and attempt again,

if you have concerns removing that command what is the impact,. better contact tac for confirmation before you proceed.

the one you upgrade success have same commands ?
