I am planning on configuring an Etherchannel between an ASR1002 and a L2 2960 switch. My question is how I should configure the etherchannel on the 2960 considering it is Layer 2. Here is my config:
ASR1002
interface g0/0/0
channel-group 10 mode active
!
interface g0/0/1
channel-group 10 mode active
!
interface port-channel 10
ip add 10.10.10.1 255.255.255.0
no shut
!
2960 Switch
interface g0/47
channel-group 10 mode active
!
interface g0/48
channel-group 10 mode active
!
interface port-channel 10
switchport node access
switchport access vlan 80
!
The reason for this is that I have some Firewalls also connected to this switch on the same vlan and want traffic to flow from the ASR to the firewall through the switch. Do I need to make it a layer 3 connection betwen the switch and the ASR, or will this work? Seems to me like it would work, just as if I had a server connected on the other end of the etherchannel.

Guess the links connecting to the firewalls are not bundled, right? In that case, your config looks good.

I may bundle a couple links to the firewalls for increased bandwidth, but that should't be an issue right?

try setting one end of your config to be passive instead of active, if I remember correctly active + active won't form a channel correctly.
