Trunk & Tag - YES; everywhere you can as long as it fits your security model.

 

LACP/PAgP - YES, use LACP (you can't use PAgP since it is Cisco proprietary).

 

Speed/Duplex - Autonegotiate; as a rule I always autonegotiate if it is 1000mb.

 

 

As for the config on your Cisco switch, it should look something like this with most of the config taking place on the port-channel and not the individual interfaces:

 

 

interface Port-channel1

 

description BigIP1

 

switchport

 

switchport trunk encapsulation dot1q

 

switchport trunk native vlan 999

 

switchport mode trunk

 

switchport nonegotiate
