Solved: LACP using 2x 10G ports not showing 20G?

I currently have etherchannel configured to 2x 10g ports.

(this will take down your port-channel)

Your description is 'LACP...' yet you are using PagP. Issue below commands on both physical interfaces. Does this change the speed of the port-channel?

'no channel-group 42 mode desirable'

'channel-group 42 mode active'

Hi WannaB

Oops you are right the configuration is in PagP. However I have another port channel from the 7706 to Fabric Interconnect which is configured as LACP that is still operating on 10G.

Is the NIC teaming on the other end setup to use both NICs or for failover only?

Thanks WannaB

show int port-channel xx shows the total bandwidth :)

Our 7606 shows

but ASR1004 had a bit different output

    No. of PF_JUMBO supported members in this channel : 2

but in both outputs BW 20000000 Kbit/sec. So this is a cosmetic bug in output.

Looks normal to me , you have a link in your port channel down.

hi steven

I would say that it is correct - the bandwith is 20Gbps
