Get MAC

You don't tell us what your router is. If your router has appropriate software, you can query it's arp table via SNMP; or you could log in and tell it to display the arp table. Or you could examine the spanning tree negotiations in detail.

Very sorry for late reply! My router is Cisco SOHO 91! I can retrieve the the local and router's MAC addresses by using this command

show ip arp

but it doesn't show the MAC of the bridge. Any comment?

The mac will only be in the arp table if there has been some communication to it within the lifetime of the arp entries. Ping the bridge from the device that you will display the arp table from and then you should see it.

Hope that helps,

The IP of Ethernet1 of the router is 202.123.123.23, and the IP of the Bridge is 192.168.23.45. I can ping the the Bridge, but when I use this command

show ip arp 192.168.23.45

Nothing happen!! Help please!

Simply use ethereal

But I thinkg ethereal cannot bypass router! That's why it can't capture the bridge's MAC address!
