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. This was because the entire chassis of course booted. The secondary module did however become the primary almost immediately following the reload command. Now I figure that if I just removed the primary blade the system would failover immediately and not reboot my 10/100/1000 blades. To my surprise, this resulted in again 1 minute and 50 seconds downtime and network connectivity was restored. BTW The blades also appeared to reboot. In terms of High Availability am I missing something? Considering these results what would deter me from just sticking to HSRP. I am a novice and looking for some constructive input. With that said note the following: [snip] Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=51684&t=51654 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
