Software upgrade 6832-x-le

I have two Cisco C6832-X-LE connected by switch mode virtual. Both switches are currently running 6848x-ipservicesk9-mz.SPA.152-2.SY1.bin and I would like to upgrade them to c6848x-ipservicesk9-mz.SPA.155-1.SY7.bin. What I am look for is the correct CLI path to upgrade these devices.

1.  Copy the IOS file to the Active unit: 

 copy tftp://<TFTP_IP_ADDRESS>/IOS_filename.bin bootdisk:

2.  Copy the ROMMON file to the Active unit: 

copy tftp://<TFTP_IP_ADDRESS>/c6840x_rm.bin.SPA.152-02r.SYS2 bootdisk:c6840x_rm.bin.SPA.152-02r.SYS2

3.  Copy the IOS file to the Secondary unit:  

copy tftp://<TFTP_IP_ADDRESS>/IOS_filename.bin slavebootdisk:

4.  Copy the ROMMON file to the Secondary unit:  

copy tftp://<TFTP_IP_ADDRESS>/c6840x_rm.bin.SPA.152-02r.SYS2 slavebootdisk:c6840x_rm.bin.SPA.152-02r.SYS2

5.  Upgrade the Active supervisor's ROMMON:  

upgrade rom-monitor switch 1 slot 1 file bootdisk:c6840x_rm.bin.SPA.152-02r.SYS2

6.  Upgrade the Secondary supervisor's ROMMON:  

upgrade rom-monitor switch 2 slot 1 file slavebootdisk:c6840x_rm.bin.SPA.152-02r.SYS2

7.  Change the boot variable string to point to the new IOS

conf t
 no boot system flash bootflash:old_ios.bin
 boot system flash bootflash:NEW_ios.bin
 boot system flash bootflash:old_ios.bin
end

Read the release notes and understand the bugs and caveats ( you required  FPGA flash upgrade)

 

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst6500/ios/15-5SY/release_notes/release_notes_15_5_SY.html

 

I will not use ISSU or efsu, never had good results, i use fast upgrade as below : ( do this upgrade in maintenance window)

WARNING:  DO NOT USE ISSU or FSU/eFSU.

Read the Release Notes very carefully. 

The ROMMON will need to be upgraded.

  • ROMMON may not be "found" in the 6832 download page but the file can be found elsewhere (LINK).
  • ROMMON cannot be upgraded using ISSU or FSU/eFSU.  

NOTE:  15.5(1)SY8 was released 17 September 2021.

Leo,

If I do not use ISSU or FSU/eFSU. Is there a document that would give me a good understanding of the steps that would need to take place to upgrade a 6832 switch? 

did you get a chance to look at the URL post before the upgrade?
