Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Workaround: Change the Cisco 2800 series router’s (CE) configuration to use a sub-interface for the
vlan-id instead of using the vlan- dot1q vlan-id command on the main interface. With a
sub-interface configured on the 2800, we can verify that the ARP packets are sent with proper
VLAN ID.
