Troubleshooting with EEC 14-11
Table 14-6 Troubleshooting the Password
CORRECTIVE ACTION
Refer to section 13.4 to upload the default configuration file. This returns all of the settings to default values, so
you lose any configurations you have made.
14.7 Local Server
The computer behind a DSL modem or router cannot access a local server connected to the IES-2000/3000.
Table 14-7 Troubleshooting a Local Server
STEPS CORRECTIVE ACTION
1 Refer to section 14.2 to make sure that the subscriber is able to transmit to the line card.
2 Make sure the computer behind the DSL device has the correct gateway IP address configured.
3 Check the line card’s VLAN configuration (refer to the chapter on bridge commands and the chapter
on IEEE 802.1Q tagged VLAN commands.
4 Check the cable and connections between the IES and the local server.
5 Try to access another local server. If data can be transmitted to a different local server, the original
local server (that could not be accessed) may have a problem.
14.8 SNMP
The SNMP manager server cannot get information from the line card.
Table 14-8 Troubleshooting the SNMP Server
STEPS CORRECTIVE ACTION
1 Ping the line card from the SNMP server. If you cannot, check the cable, connections and IP
configuration (see the chapter on IP commands).
2 Check to see that the community (or trusted host) in the line card matches the SNMP server’s
community. If these steps fail to correct the problem, contact the distributor.
14.9 Telnet
I cannot telnet into the line card.
Table 14-9 Troubleshooting Telnet
STEPS CORRECTIVE ACTION
1 Make sure that a telnet session is not already operating. The line card only accepts one telnet
session at a time.
2 Check that the client IP address(es) match the configured secured host IP address(es), refer to the
secured host commands in the chapter on system commands. The line card immediately
disconnects the telnet session if they do not match.
