CAT6509 with redundancy IOS upgrade procedure

Unanswered Question

Hello guys, I need some direction on an upgrade procedure for CAT6509 with redundancy. boot system flash disk0:s72033-ipservices_wan-vz.122-18.SXF9.bin.

I'm not sure if I should upgrade the secondary box first (which is off line) and then force the fail over on the primary (then upgrade it).

Thanks I appreciate it.

I have this problem too.

Hi jcoke Thanks for your quick reponse I appreciate it. I forgot to mention that there are 2 6509's which are configured as HSRP with prempting, both have redundant SUP's. The current setup is that the first box is configured as Root primary for all of the VLAN's and is the primary for HSRP.

I'm planing to shutdown all of the interface on the first box (to force the secondary box to take over and then upgrade IOS the primary & secondary SUP's).

Then after the first box is upgraded, do the same on the second box. Please let me know if im on the right path.

Thanks again.
