I got 02 x 4507R chassis. I want to perform IOS upgrade. It is in SSO mode. The config-register is 0x2101.
From this URL, http://www.cisco.com/en/US/partner/docs/switches/lan/catalyst4500/12.2/37sg/configuration/guides/issu.html#wp1091552, under Prerequisites #1, it mention need to change the BOOT/config-register parameter of the standby supervisior engine first
How do I go about? Does that meant that I change the ocnfig-register to 0x2102 on active engine, issue redundancy reload peer command and proceed to do issu loadversion?
