MANAGED, HIGH-SPEED NETWORK MODEM USER GUIDE

8.SNMP cannot locate the modem.

If your NMS is unable to find the XL-12000S modem during auto-discovery, try the following steps:

a.Try to ping the modem interface to determine if there is a network connection to the modem. If ping is still not work- ing, double-check your network configuration (also see #9 below).

b.Verify that the NMS “get” community name matches one of the modem’s configured community names. If the NMS and modem community names do not match, change either one to match with the other.

c.Verify that the NMS IP address matches the modem’s con- figured source IP address for “get” community name used by the NMS. If the modem source IP address for the “get” community name is different than the NMS, you may want to either a) change the modem source IP address for that community to be the NMS IP address, or b) if there are multiple NMS’s which want to communicate with the modem using the same community name, then configure the modem with multiple entries with the same community name but with separate source IP addresses.

d.Manually enter a node for the modem in your NMS node map. (Some NMS products’ auto-discovery mechanisms do not always find all nodes). After manually entering the node, try to request a “system” object from the modem.

9.Changes were made to the modems IP Address(es) and the modem is now unavailable via Telnet or ping.

If the IP address(es) have recently changed on the modem, the IP ARP cache may be inaccurate. Flush the IP ARP caches on routers and PCs trying to reach the modem.
