Others it won't work on is a 1720 FA int. Been burnt by this before. (unless
of course code has fixed this by now)

Subject: RE: 802.1q trunking on ethernet interfaces
Only certain router ports will support 802.1q trunking.
There are individual cases, where a 10 mbit port will do 802.1q
(WIC-1ENET and Eth ports on 261x non-XM routers, others anyone), but the
general rule remains - you need a 100 mbit port for 802.1q. It will work
on a 10/100 mbit port set to 10 mbit. This is not a limitation in the
IEEE standard, but a limitation in router hardware.

Boyan
