Local Server

The computer behind a DSL modem or router cannot access a local server connected to the IES-1000.
STEPS
1 Refer to section 21.2 to make sure that the subscriber is able to transmit to the IES-1000.
2 Make sure the computer behind the DSL device has the correct gateway IP address configured.
3 Check the IES-1000's VLAN configuration (see the VLAN chapter).
4 Check the cable and connections between the IES-1000 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.
21.9

SNMP

The SNMP manager server cannot get information from the IES-1000.
STEPS
1 Ping the IES-1000 from the SNMP server. If you cannot, check the cable, connections and IP
configuration.
2 Check to see that the community (or trusted host) in the IES-1000 matches the SNMP server's
community. If these steps fail to correct the problem, contact the distributor.
21.10

Telnet

I cannot telnet into the IES-1000.
STEPS
1 Make sure that a telnet session is not already operating. The IES-1000 only accepts one telnet
session at a time.
2 Make sure that the IP address of the computer you are using matches a range of secured hosts
configured in Secured Client under Maintenance in the IES-1000. The IES-1000 immediately
disconnects the telnet session if they do not match.
3 Ping the IES-1000 from your computer.
If you are able to ping the IES-1000 but are still unable to telnet, contact the distributor.
If you cannot ping, check the cable, connections and IP configuration.
4 If you are attempting to telnet from a DSL port, refer to section 21.2 to make sure that you can
transmit data to the DSL port.
