c9300 stack upgrade

[DraganSkundric87318]

hi,

i have stack of two c9300 switches 24S and 24T. Download page has different dowload links fot these different version of switches but sha256 signature are the same for these bins, so I guess that ioses are the same and that install procedure in wich active switch installs new ios on all members will work ok?

Hello @DraganSkundric87318,

Yes you're right!

Hi @DraganSkundric87318 

You are right. The IOS is the same on this case.

 Below the requirements for stack.

Restrictions for Switch Stacks

The following are restrictions for your switch stack configuration:

• Only homogenous stacking is supported, that is, a stack of Cisco Catalyst 9300 Series Switches stack with only Cisco Catalyst 9300 Series Switches as stack members.

  Cisco Catalyst 9300L Series Switches stack with only Cisco Catalyst 9300L Series Switches as stack members.

  C9300-24UB, C9300-24UXB, and C9300-48UB switches can only be stacked with each other.

• During a switchover, when the standby device syncs with the active device, the following log message is displayed on the console:

  %SM-4-BADEVENT: Event 'standby_phy_link_up' is invalid for 
  the current state 'NO_NEIGHBOR': rep_lsl_rx Gix/x/x -Traceback=

  Ignore this message. It does not have any functional or operational impact.

• You cannot have a switch stack containing a mix of different license levels.

As you can see, none of the restriction applies to you.
