Re: Multiple Supervisors, 6509 Chassis; Native IOS [7:51654]
I'm sorry Larry if I've caused any confusion but I only have a single 6509 with two supervisor 1 blades with msfc 2 in slots 1 and 2. Clay, I began to read the URL you posted and noticed in the second paragraph it states, This paper is based on the hybrid software model for the Cat6500 Series...and not the Cisco IOS running natively. With that said please note the native IOS places these commands into the startup config by default; also I haven't been able to change these commands thus far: ! redundancy main-cpu auto-sync standard ! Jagan, I'm glad I'm not the only one! So I suppose its safe to conclude running native IOS on a 6509 w/two supervisor1 msfc2 modules yields a failover time of approximately 90-120 seconds. - Original Message - From: Larry Letterman To: Sent: Tuesday, August 20, 2002 1:34 AM Subject: RE: Multiple Supervisors 6509 Chassis; Native IOS [7:51654] If you have two gateways(6509's) why goto the expense of two msfc's in each chassis ?

Re: Multiple Supervisors 6509 Chassis; Native IOS [7:51654]
Well, one good reason to have 2 sups in each chassis is that if one Sup does die, sure HSRP will kick in and the other 6500 will be the gateway, but only for the devices connected to the switch that's still up all of the devices on the 6500 that had the Sup die will be down and down hard (unless there is some way that Layer 2 functions continue even tho the sup died which I can't imagine). With a second Sup, at least after about 2 minutes, all of those devices will have connectivity restored as well. Mike W. Larry Letterman wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

In Native IOS mode, you *can't* run both Sups at the same time, so there is no performance hit from running in software mode.. the primary Sup does all of the work... If it fails, then the backup takes over and become primary, so again, there shouldn't be a performance difference Mike W.

Re: Multiple Supervisors 6509 Chassis; Native IOS [7:51654]
I've been reading about the high availability in the 6500 (since we have one and are getting over a dozen more). What I understand so far is that the existing flows are used for about 2 minutes while the new active supervisor/MSFC relearns the network (routes, MAC's, etc). Not my idea of high availability. So, existing sessions should continue fine. New stuff may have a problem. Note: I've been concerned with Hybrid mode (CatOS + IOS), not native. I'm not ready to tackle that yet. :-) Maximus 08/19/02 11:48AM This is how I learn: =) Running IOS on my 6509, I wanted to see the amount of downtime I would cause by deliberately causing the primary SUP to fail by one executing a reload on the primary module and two simply pulling the primary from the chassis. heeheehee What I found was the reload caused approximately 2 minutes downtime.
