Re: Cisco WS-C4503-E VSS Switch upgradation procedure

preetpeethambaran · ‎07-17-2019

Hi,
I am looking for complete step by step upgradation commands for Cisco WS-C4503-E switches in VSS, as we have a scheduled activity next week for IOS upgradation.

Currently Cisco 4503 is running on 03.07.03.E Version, please let me know the latest stable Cisco recommended version to be upgraded.

Switch is running on Sup 7L-E 10GE,
I am still bit confused, so ISSU is not the recommended method of upgrade right.

Is there any KB article for the second method. Just to get more clarity, please let me know if below is the complete VSS upgradation step for second method.
1) Upload latest ios image on active & standby 4503-E switches.
    copy tftp: bootflash:     -- Active switch
    copy tftp: slavebootflash:    -- Standby switch
2) Configure the boot image to newly uploaded ios & save configuration
   boot system flash bootflash:ios.bin     -- Active switch
   boot system flash slavebootflash:ios.bin   - Standby switch
3) Reload standby switch first & then active switch.
redundancy reload peer   -- Standby switch
redundancy force-switchover or   redundancy reload self   -- Active switch
Please let me know, if there are any details missing/to be modified for the VSS upgradation for C4503-E switches.
Also, please suggest the latest stable ios version & is ROMMON upgrade required before an IOS upgradation
Below are the version details.

This is unnecessary.

YOU need to read the Release Notes (not us).

Read the Release Notes carefully. There are certain versions which require a ROMMON upgrade before an IOS upgrade can be conducted.

Cisco method of VSS IOS upgrade can be found HERE.

Alternate method can be found HERE.
