Hi,
sub interface only with as part of an IEEE 802.10 or ISL vLAN
or for IPX..
Not for appletalk.
You must have 100baseTX or 100BaseFX, or more.
You can't with 10 base T.

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
