That's interesting. We've been using the Arrowpoint switch for load-balancing with sticky SSL sessions for over a year now and have had no problems at all.
However, we're going to be replacing that box with two of something-or-other, we just haven't decided on what yet. John >>> "sam sneed" 3/22/02 8:35:56 AM >>> First off, failover takes close to a minute which is a lot more than Cisco advertises(in HA config). Second they're supposed to provide for load balancing using SSL. This simply does not work on ours even though we followed the config on their site exactly. Third they're very tempermental. We migrated them to another switch and expected a little downtime during the move. We moved them, they came up, showed all services were good but in actuality all services were down. We had to power down both CS11152 and the Extreme switch they were connected to get services back up. Mind you that all the servers that were behind the CS11152 were pingable and reachable up to Layer 3 so NAT and L3 were working, only the services the load balancers were supposed to provide were down. Cost us a lot of aggravation and almost my job.
