MP-1xx SIP User’s Manual 11. SNMP-Based Management
Version 4.4 185 March 2005
11.6 SNMP Interface Details
This section describes details of the SNMP interface that is required when developing an Element
Manager (EM) for any of the media gateways, or to manage a device with a MIB browser.
Currently, both SNMP and ini file commands and downloads are not encrypted. For ini file
encoding, refer to Section
F.1.2 on page 221.
11.6.1 SNMP Community Names
By default, the device uses a single, read-only community string of ‘public’ and a single read-write
community string of ‘private’.
Users can configure up to 5 read-only community strings and up to 5 read-write community
strings, and a single trap community string is supported:
11.6.1.1 Configuration of Community Strings via the ini File
SNMPREADONLYCOMMUNITYSTRING_<x> = '#######'
SNMPREADWRITECOMMUNITYSTRING_<x> = '#######'
where <x> is a number between 0 and 4, inclusive. Note that the '#' character represents any
alphanumeric character. The maximum length of the string is 20 characters.
11.6.1.2 Configuration of Community Strings via SNMP
To configure read-only and read-write community strings, the EM must use the srCommunityMIB.
To configure the trap community string, the EM must also use the snmpVacmMIB and the
snmpTargetMIB.
To add a read-only community string (v2user):
• Add a new row to the srCommunityTable with CommunityName v2user and GroupName
ReadGroup.
To delete the read-only community string (v2user), take these 2 steps:
1. If v2user is being used as the trap community string, follow the procedure for changing the
trap community string (see below).
2. Delete the srCommunityTable row with CommunityName v2user.
To add a read-write community string (v2admin):
• Add a new row to the srCommunityTable with CommunityName of v2admin and GroupName
ReadWriteGroup.
To delete the read-write community string (v2admin), take these 2 steps:
1. If v2admin is being used as the trap community string, follow the procedure for changing the
trap community string. (See below.)
2. Delete the srCommunityTable row with a CommunityName of v2admin and GroupName of
ReadWriteGroup.
