It takes about 5 minutes for the MLX to boot up after the firmware upgrade. Huge chassis, Cisco Catalyst opens fast from edge switches, amazing 🙂
Before the upgrade, the Release Notes should be read carefully. There may be unsupported old line cards and management modules in the new firmware.
I want to migrate MLX to 5.8f firmware. In my case it says we can switch to 5.6c then 5.8f. I will do a two step firmware update.
I have clustered MLX switches with MCT before. So I’ll do one first, then the other.
1) I start by saving the configuration and backing it up.
wr mem
copy run tftp
2) I don’t want it to be an afterthought so I isolate the device from the other and edge switches. By the way I need to access it via MGMT.
conf t
int e 5/1 to 5/24
disable
int e 1/1 to 1/24
disable
int e 2/1 to 2/24
disable
int e 3/1 to 3/24
disable
int e 4/1 to 4/24
disable
3) I will upgrade all linecard, management, switch fabric modules at once using the manifest file. Upgrade will be completed in two steps.
i) First step:
copy tftp system all-images <TFTP-SRV-IP> manifest XMR-MLX05600c_Manifest.txt
ii) Second steop:
copy tftp system all-images <TFTP-SRV-IP> manifest XMR-MLX05800f_Manifest.txt
4) I check the boot firmware with the “show flash” command. In versions before 5.6.00d, the boot is not updated. Again, the release notes information 🙂
After firmware upgrade
I set tftp server “XMR-MLX\Boot\ManagementModule” and update boot.
copy tftp flash <TFTP-SRV-IP> xmprm05600.bin boot
I set tftp server “XMR-MLX\Boot\InterfaceModule” and update boot.
copy tftp lp <TFTP-SRV-IP> xmlprm05600.bin boot all
5) I check “show flash” again, if the upgrade is complete then I do a check.
reload-check
reload
6) When the system boots up after 5 minutes (it takes 45-50 minutes to update the firmware), I check show flash, show ver, show module, It’s DONE.
