you can create 3 port LACP trunk and 1 stand alone connection inside of an FSN , when the new switch gets installed move the stand alone connection there. Another option is to create two 2-port LACP trunks and add them to an FSN (one trunk will be standby), and then move the standby trunk to the new switch.
Friends, we have 2 blade servers on an NS480 unit. Each blade server has 4 ethernet ports (Cge0-3). We only have one network switch. Ideally would like to have 2 switches for redundancy instead of 1. What's the best way to connect/configure? Please advise.   Thanks, RP
