ME3400 problem to forward layer2 between the interfaces
I'm having a problem with a ME3400 switch. When the interfaces are configured to work as a switch, the layer 2 traffic is not forwarded between the switch. I tried to put two devices on the same net (10.0.0.1/24 and 10.0.0.2/24) and send ping packets from the 10.0.0.2 to 10.0.0.1, but the ICMP packets aren't received.
If I configure two interfaces with diferent IP adresses (10.0.0.1/24 and 10.2.2.1/24) and enable de "ip routing", the switch can route the packets without no problem.
I already tried to reset the switch to default factory config, upgrade and downgrade the IOS, but the problem is the same.
The only thing that I can think of is, when in L2, are the two devices on the same vlan? If they're in separate vlans, you won't be able to ping between them. Make sure that both ports are configured for the same vlan, disable routing, and then you should be able to ping between as long as they're in the same subnet.
