With the 4500-E switch, how do multiple separate 802.1Q aggregation trunks on a single VLAN work so that they don't interfere with each other?
Am I understanding correctly, that all I need to do switch-side with the Cisco Network Assistant, is to select each of the ports, make them all "802.1Q trunk ports" and nothing more needs to be done to group these separate ports into multiple separate trunks?
If yes, then what keeps these various multiple 802.1Q trunk ports from getting mixed up or confused by the switch, with multiple trunks all within the same VLAN and switch?
,
Scenario.... 4500-E switch with
- one 4 gigabit 802.1Q trunk
- three 2 gigabit 802.1Q trunks
- one 3-gigabit 802.1Q trunk
- multiple other typical 1-gig computer links
These groups of server NIC ports each have link aggregation enabled on each server OS:
Port 1 - 802.1Q trunk port -> Server #1, NIC port A
Port 2 - 802.1Q trunk port -> Server #1, NIC port B
Port 3 - 802.1Q trunk port -> Server #1, NIC port C
Port 4 - 802.1Q trunk port -> Server #1, NIC port D
Port 11 - 802.1Q trunk port -> Server #2, NIC port A
Port 12 - 802.1Q trunk port -> Server #2, NIC port B
Port 13 - 802.1Q trunk port -> Server #3, NIC port A
Port 14 - 802.1Q trunk port -> Server #3, NIC port B
Port 15 - 802.1Q trunk port -> Server #4, NIC port A
Port 16 - 802.1Q trunk port -> Server #4, NIC port B
Port 19 - 802.1Q trunk port -> Server #5, NIC port A
Port 20 - 802.1Q trunk port -> Server #5, NIC port B
Port 21 - 802.1Q trunk port -> Server #5, NIC port C

Sure. Give them different Etherchannel numbers.

Do your servers support LACP?
If not, have you configured them with static etherchannels?
