(please show the actual tcpdump output; what i expect is that the epair interface shows ARP packets with a .1q tag for VLAN 60.) > Thanks Gents! ahem --SO7tiUkpl3bWZSmR Content-Type: application/pgp-signature; name=signature.asc -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQSyjTg96lp3RifySyn1nT63mIK/YAUCaOYVUwAKCRD1nT63mIK/ YMXhAP4lzOAUeNt0FhCRDoUvN4CrtGwvb/su9tH/TNvoHTaPBAEAnBunABBQ9REG a5B1us1/emhH/HMpdxvP0e5iQOXhZAI= =HIIB -----END PGP SIGNATURE----- --SO7tiUkpl3bWZSmR--
