Re: interesting behaviour of the switches

Hello no I did mean just ping 30.30.30.2 command from the switch.
50.50.50.2is the only ip address configured on the switch. For
example: vlan 50
ip add 50.50.50.2 255.255.255.0

In anyway I will send you config tomorrow when I will have again access to
those swithces. But the configs are simple.

2. The second question would be like this: If a switch doesn't have a route
or default-gateway configured. Will it not send a packet or will it
broadcast a packet according to the switch nature?
