3.4.2.3 SNMP
The management with SNMP (Simple Network Management Protocol) is used to monitor the status,
to configure and to manage any network equipment. The big advantage of SNMP is usually the
immediate unasked information (TRAP) if something is not running correct. Etherlink_IV DSL
modems support SNMP v1. The management control computer should have a special SNMP
program installed.
The following management information bases (MIBs) are supported:
RFC1213-MIB, a standard MIB for all devices, supporting MIB II and described in RFC-
1213, is fully supported
IF-MIB, MIB descriptions of interfaces, described in RFC-2863, is fully supported
DS1-MIB, MIB describing E1 streams, RFC-2495, is partially supported
Traps are sent by the device into two addresses. The following traps are supported:
cold Start (RFC1215)
authentication Failure (RFC1215)
linkUp (RFC1213-MIB, IF-MIB)
linkDown (RFC1213-MIB, IF-MIB)
dsx1LineStatusChange (DS1-MIB)
An SNMP agent should be installed to work with SNMP. The COMMUNITY command (configuration
of the community parameter of SNMP messages) and the TRAPIP command (configuration of IP-
addresses for traps) are used to configure the SNMP agent. The IP-address and the other network
configurations of the SNMP agent coincide with network configurations of the device (see SETIP,
NETMASK, GATEWAY commands and the NET sub-menu).
Using the variables described in the MIB the following actions can be performed:
view general information about the device
monitor the general status of the device (presence of alarms)
reboot the device
configure the device, control configurations (use, acknowledge), backup and restore
configurations
view and clear G.826 statistics for E1 and DSL
view alarm status
Every variable of the S-Access-MIB, as well as of all other MIB files have a detailed description in
the MIB file itself.
The MIB can be received from S-Access GMBH
