Thanks, Martin. I thought that the native VLAN would come through on the 
VLAN interface as well.  While this would explain why I couldn't get at 
VLAN 494, it wouldn't explain why I couldn't get at another of the VLANS 
on the same link -- still no traffic.  I do a tcpdump and see nothing (but 
the LACP stats show the link is up).
