Chapter 18 Maintenance and Troubleshooting
Resolving problems
Verify that the encapsulation is correct.
Verify that the addressing mode is set correctly (IPCP/Static).
Verify that the username and password are correct.
Issue
I have a PPPoE connection and I get a PPPoE FAILED message.
Resolution
Verify that the VPI-VCI is correct.
Verify that the encapsulation is correct.
Verify that the addressing mode is correct.
Verify that the user name and password are correct (including case).
Check for a VLAN.
Issue
I'm on an ADSL circuit and I have a Bridged Ethernet connection and I get a DCHP FAILED
message.
Resolution
Verify that the VPI-VCI is correct.
Verify that the encapsulation is correct.
Verify that the DHCP server isn't out of addresses. (Contact your IT department or help desk.)
Issue
I get an INVALID CONFIG message.
Resolution
Verify that a valid IP address is being used (examples of invalid IP addresses would be *.*.*.0 or
127.*.*.* or 10.0.0.1 or 192.168.0.0).
Verify that the IP address and gateway are on the same network as defined by the netmask.
Check the netmasks if Ethernet IP = DSL IP. The netmasks must be different.
Verify that the Netmask is not set to 0.0.0.0.
Issue
The Frame LED is green, but IP pings are not working.
Resolution
A green Data status indicator does not guarantee an IP ping (or any routed/bridged packet) will be
treated properly once it leaves the unit. In an Ethernet bridged or IP over ATM environment with
static addressing, there is no initial communication with the far end, so as soon as ATM sync occurs
the interface is deemed active to pass user data.
