Re: Switches with Dynamips!

Hi Vijay

[[ETHSW SW1]]
1 = access 101

You have to configure vlan 101 on the breakout switch. As per the example R1
f0/0 goes to access port vlan 101. So let's assume you configure port f0/24
on the breakout switch as an access port belonging to vlan 101. This will be
considered as a port belonging to R1.

Now from f0/24 on the breakout switch, connect to the real switch port (3550
or 3560) as per the physical topology.

*I have one more doubt, if we configure the breakout switch port to an
access port (vlan 101) it means that we have to configure the same vlan on
the real switch port correct?*

By real switch, I assume you mean the 3550 or 3650. You configure vlans on
it as per your logical topology. You dont need configure vlans on the
breakout switch again on those switches.

I am not so sure whether router on stick is possible through this method.
The best thing is to try it out. Given the option, I would always go for
quad NICs. Have you also thought about using USB NICs?
