3.12 SNMP Support

In addition to managing GRT-101 by means of the command-line applications

and web browsers, you can manage the unit by using a simple network

management protocol (SNMP) management station. GRT-101 can generate

SNMP traps to indicate alarm conditions, and it relies on SNMP community

strings to implement SNMP security. Currently, SNMP (RFC 1157) and

SNMPv2c (RFC 1901) agents are implemented. Also, the management

information bases (MIBs) supported by GRT-101 include MIB II right now.

3.12.1 SNMP community

The below example adds GRT-101 into a SNMP community “private”, with

read/write access right for SNMP managers in the same community.

admin# admin snmp community 1 edit enable private read_write

To show the setting of SNMP communities with access right, type:

admin# admin snmp community 1 list

SNMP Community Pool

No Community Access Right

---- -------------------------------- ------------------

1 private Read_Write

2 (Empty)

3 (Empty)

4 (Empty)

5 (Empty)

To disable the SNMP community 1, enter the following command:

admin# admin snmp community 1 edit disable private read_write

To save your changes, enter:

admin# write

3.12.2 SNMP trap

GRT-101 can generate alarm conditions to SNMP manager via SNMP traps.
