Trunk ports for bandwidth and failover?
Is it possible to trunk 2 ports from a 6400 to a Cisco switch so that both wires act as a single wire? This would give us increased bandwidth while both wires worked and would allow redundancy if one ...
Be aware that ion the cisco it's called a port-channel. On cisco, a trunk is an interface that handles tagged (802.1q) VLAN's
On the cisco it should be configured with something like
interface port-channel201
description port-channel to an F5
switchport
switchport trunk encapsulation dot1q
switchport native vlan 999
switchport trunk allowed vlan
switchport mode trunk
Then on the interfaces themselves you have something like
interface gi3/36
description F5 interface 1
switchport
switchport trunk encapsulation dot1q
switchport native vlan 999
switchport trunk allowed vlan
switchport mode trunk
channel-protocol lacp
channel-group 201 mode active
The native VLAN 999 just allows traffic on a particular VLAN is 802.1q headers are missing. You can add things like spanning-tree portfast etc or other embellishments as required.
