Can a Cisco AS5300 support 802.1Q encapsulation on its fast ethernet interface (DEC21140AE hardware), and can it, with an appropriate release and feature set of IOS, support inter-VLAN routing via subinterfaces?
If so, what minimum feature set and release of IOS is required?
Thanks.

I dont see any reference to 802.1q on the AS5300 on Ciscos web. I would guess its not available yet. You should check with your Cisco office/rep to be sure.

I happen to have an AS5300 with an unused FE interface, and to answer your question I created a sub-interface and checked to see what encapsulations are supported:
Router#config t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#int f0.1
Router(config-subif)#enca ?
dot1Q IEEE 802.1Q Virtual LAN
isl Inter Switch Link - Virtual LAN encapsulation
sde IEEE 802.10 Virtual LAN - Secure Data Exchange
And the hardware type is DEC21140.
The router is running this image:
c5300-is-mz.122-6a.bin
which is IOS 12.2(6a) "IP Plus"
I don't see any problem implementing inter-Vlan routing ...
Hope that helped,
Mustafa
