I have dual Supervisor Vs in a 4510R chassis and want to configure them for the smallest possible interruption in the event of a switchover. The 30 seconds or so that it takes with SSO is longer than we'd like.
NSF with SSO looks like the most promising solution, but can it be configured like this in the 4500? The only specific documentation I found relates to NSF with SSO across devices/sites. The commands they list do not take. http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SXF/native/configuration/guide/nsfsso.html
Thanks in advance. I just got my CCNA and I'm loving this stuff!
Supervisors Product Number = WS-X4516
Catalyst 4000 L3 Switch Software (cat4000-I5S-M), Version 12.2(25)EWA11
Starting with Cisco IOS Release 12.2(31)SG, the Catalyst 4500 series switch supports NSF-capability.
IOS upgrade. :)
