I am just wondering and to understand more:
In a C7000 encosure with 6 VC Ethernet modules loaded (3 active, 3 standby and Four 1GB uplink port on each Ethernet module) and, if we uplink all the ports on the active bays 1,3,5,7 to a single uplink ether channel and standby bay module ports on 2,4,6,8 to another single uplink ether channel connected to a different switch, using trunk option in a cisco switching environment.
Do i get 16GB trunk throughput of active and 16GB throughput of standby. Any issues with this coniguration?
Solved! Go to Solution.

SolutionWhat you could do is buy 10GB CX4 0.5m stacking cables and connect up all the VC modules then you could have four 8GB trunks.
As for active/passive - that depends on your VC network design. You could have them all active.

Re: c7000 and uplink throughput
Assume if we have two different active 4gb Access port uplinks from different vc ethernet module.
Later if we add the whole active 8 gb uplink nics(4gb + 4gb)connected to a single vmware virtual switch, how does it behave.

Re: c7000 and uplink throughput
So as long as you configure all 8 ports in an etherchannel trunk at the switch end (single or stacked switchs) on the VC end they will auto configure to an 8GB trunk.

Re: c7000 and uplink throughput
heregoes more details.
One ether channel access port for 4 uplinks in VC module-1
One more ether channel access port of 4 uplinks in VC module-3
So i have total 8Gb uplink, if we combine alotgether in vmware virtual switch.
I am sure this creates routing issues, because of two different ether access channels, combined using vmware vswitch.
But, just searching is this option works really or not.

Re: c7000 and uplink throughput
So thats "Scenario 10: Network failover with LACP" in the Virtual Connect Ethernet Cookbook. "The uplinks connected to VC-Enet module 1 and 3 cannot be combined for aggregated bandwidth". So its 4GB Active/4GB Passive.
Take a look at Scenario 11, 12A or 12B in the cookbook to get 8GB usable bandwidth.
