[c-nsp] Sub Interfaces on 3660

[Voll, Scott]

Is your laptop tagging ISL?  Unless a trunk is setup between the router
and switch and your configured for ISL over that trunk and tag your port
the Laptop is plugged into you won't be able to ping it.

Subject: [c-nsp] Sub Interfaces on 3660

I am trying to setup Ethernet sub internfaces on a 3660.   I can create
the
interface and ping it from the router but when I connect my laptop up to
the
port and try and ping the same IP I get nothing.  I am sure I am missing
more.    The Google lottery turns up some stuff about bridge groups but
it's
turning up more sales type documents than how tos.

 

What I am trying to do is  I physically connecting FA0/1 to a Radio that
sends a point to point link to a building where I have 3 separate
networks.
I am coming out of the Radio on the far side into a switch and then out
to 3
networks (Which are the 3 sub interfaces)    After I get this working I
will
relace the private IPs with smaller subnets of public IPs.

interface FastEthernet0/1

 ip address 10.100.1.1 255.255.255.0
