Cisco 6500 - LACP traffic

[fibernet570]

I have a circuit between two 6500 switches, its 100BaseT at the customer end and Etherchannel inbetween.  The 100BaseT ports are configured with dot1q-tunnel.  The customer is sending LACP traffic, they are stating we are blocking LACP traffic.  Can this be true, on Layer2 circuit, we are blocking this type of traffic?  Pls advise.

This should work without issue.  Take a look at the 802.1q tunneling configuration guide, it shows LACP as supported:

http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/configuration/guide/dot1qtnl.html

I don't believe it's supported with "l2protocol-tunnel", since LACP is a layer-1 protocol.

Thnks Danrya, I will enable "l2protocol-tunnel point-to-point" on the 100BaseT  customer ports and not on the Fiber trunk connecting both 6500's.  This will enable LACP, PAGP and UDLD.
