Dear All
I have a big issue on Ether Channel between 6k to 5k . I found that some of ports "w" , i am unable to get the reason. My design is Cisco core switch VSS with two Cisco nexus 5k with vpc configuration . I have configure L2 port channel 108 between all "Cisco VSS , Cisco n5k VPC" .

Q1- I have issue on port channel not all ports are in p in bundle mode , only ports which connected to main core 1 on p bundle mode , but other ports which connected to second switch "w" waiting to be aggregated ?. Is it ok to put all etherchannel on same port channel 109?.
Q 2- I am going to integrate with 2 X ASR , i have to configure 2 port channels from 2 X ASR to VSS or 1 etherchannel ?
thanks

Depending on the line card of the 6500, you could be missing the command "switchport trunk encap dot1q".

Q 2- I am going to integrate with 2 X ASR , i have to configure 2 port channels from 2 X ASR to VSS or 1 etherchannel ?

Q1
Your config lacks the vpc ID. Add
vpc 109
On both Nexus switches under the port channel 109 interface.
Q2
You need 2 port channel, each going from ASR to both VSS switches.
