Synchronizing Dual-SUPs

[sbernard]

I am trying to upgrade my 9407R switch from version [Gilbraltar]16.12.03a to [Cupertino]17.9.5. However, my switch is dual-SUP. I'd like to synchronize the SUPs before upgrading, in order for both SUPs to hopefully cooperate more effectively. Could I use the following commands? Notably, these instructions are for a 4507 switch. I'll take any suggestions. 

1. Copy the new Cisco IOS software image to bootflash or slot0 on both supervisor engines with these commands:

   • On the active supervisor:

     • copy source_device:source _filename slot0:target_filename

     • copy source_device:source_filename bootflash:target_filename

   • On the standby supervisor:

     • copy source_device:source_filename slaveslot0:target_filename

     • copy source_device:source_filename slavebootflash:target_filename

2. Configure the supervisor engines to boot the new image. Use these commands:

   Switch#configure terminal
   Switch(config)#config-register 0x2
   Switch(config)#boot system flash device:file_name
   
   

3. Synchronize the supervisor engine configurations:

   Switch(config)#redundancy
   Switch(config-red)#main-cpu
   Swicth(config-r-mc)#auto-syn standard
   

4. Issue the copy running-config start-config  command to save the configuration.

5. Issue the redundancy reload peer  command to reload the standby supervisor engine and bring the engine back online (with the new version of Cisco IOS software).
