High-Level Troubleshooting
The following high-level procedures help you isolate problems to a particular
segment of the network.
T For static clients, make sure the client can Ping its own IP address. This
confirms the IP address was successfully accepted by the client computer.
T Make sure the client’s default gateway is the same as the IP address for the
Bridge Virtual Interface (BVI) on the appropriate ISP router.
T An Address Resolution Protocol (ARP) table may have invalid entries if a
recent configuration change took place anywhere on the network and not
enough time has passed for the entry to expire. Check the ARP tables on the
client, AN, and router.
T Make sure a default route is configured on the MCC card (screen A-E-A).
