It's hardware and software related. On a 2610 you can create
SubInterfaces (dot1.q only) on ethernet devices.

Ethernet0/0 is up, line protocol is up 
  Hardware is AmdP2, address is 0050.500f.58a0 (bia 0050.500f.58a0)
  MTU 1500 bytes, BW 10000 Kbit, DLY 1000 usec, 
     reliability 255/255, txload 7/255, rxload 1/255
  Encapsulation 802.1Q Virtual LAN, Vlan ID  1., loopback not set
