use "encap ISL X or dot1q X" command and it has to be 100mb interface
if you just want to assign 2nd ip to one interface use ip add x.x.x.x
x.x.x.x secondary command

Subject: subif on Ethernet
Hello,
When I try to assign an IP address to a subinterface I get the following
error:
R1(config-if)#int e0.1
R1(config-subif)#ip add
R1(config-subif)#ip address 150.10.10.1 255.255.255.0
Configuring IP routing on a LAN subinterface is only allowed if that
subinterface is already configured as part of an IEEE 802.10 or ISL
vLAN.
Why?
I tried 11.2.17, 11.2.23, and 12.0.5, all give the same error.
I know that I have created subinterfaces in the past but what version, I
don't remember what IOS version that was under.
Is there a workaround?
Also to create an ISL interface do you need fast ethernet ? or can you
do it with plain 10baseT? How do you do it?
Thanks
harbir
