ASR1000 series etherchannel

Unanswered Question
Feb 3rd, 2009

I tried several methods to do etherchannel on the ASR1006 to 3750 switch.

Method one:

port-channel 1

ip add

int g1/0/51

no switch

channel-group 1

ASR1006 configuration

int port-channel 1

ip add

int G2/1/0

channel-group 1

the port channel would show up but would not negotiate. Could not ping other end.

Other method

Switch config

vlan 2

ip add



switch trunk encap dot1q

switch trunk allow vlan 2

switch mode trunk

ASR 1006 configuration

int g2/1/0

vlan-id 2

this sets up subinterface and the example does no go from there. The router will not let you set up different encapsulations on the sub-interface.

I need a clear example to have two one gig connections from a 3750 switch to an ASR1006 to form a two gig etherchannel

I have this problem too.

see the following document ASR1000 is different then other devices about etherchannel

it uses subifs and has the concept of vlan mappings that is different from what we are used to see on switches

if you want to use it for a single vlan it will use a single GE (this was described in another thread)

Hope to help
