CISCO ME 3400 LAN configuration

By vgeoffm ·
I am using CISCO ME 3400 switch on my LAN i managed to configure and the computers on the LAN can access the internet without any problem but cannot ping other computers on same LAN. I configured Vlan1 but still cannot ping. i tend to think this may be a security feature on this router and i would like to know if there is a way of enabling ping on LAN.

Cisco ME 3400 Lan configuration

Check out the Cisco Docs on the ME 3400 Metro Ethernet Switches, especially the section on types of Private Vlans and Private Vlan Ports, this looks like the problem you are looking at.
This maybe the wrong device for your infrastructure.

Windows 7 ?

If you are using Windows 7 you may have to tell the Win7 firewall to allow ICMP packets. Go here:

Win7, by default, does not allow ICMP to pass through its firewall. Hopefully this helps you. :-)

We need a little more info. what is your switch and router configs ?
but until we see more info you may want to see that the switch ports have been assigned the correct VLAN number, and that the PC's firewalls have been configured to respond to pings.

one way to check the firewalls of the PC's is to plug them into an unmanaged switch (no VLANS).
you should be able to ping between the PC's on the same sub-net.
