MultiVoice Gateway System Administration
SNMP administration support
MultiVoice Gateway for the MAX— User’s Guide Preliminary November 23, 1998 10-23
Setting community strings
The Read Comm parameter specifies the SNMP community name for read access (up to 32
characters), and the R/W Comm parameter specifies SNMP community name for read/write
access.
Setting up and enforcing address security
If the Security parameter is set to No (its default value), any SNMP manager that presents the
right community name will be allowed access. If you set this parameter to Yes, the MultiVoice
Gateway checks the source IP address of the SNMP manager and allows access only to those
IP addresses listed in the RD MgrN and WR MgrN parameters, each of which specifies up to
five host addresses.
Resetting the MultiVoice Gateway and determining whether it has reset
You can use SNMP (sysReset object) to reset a MultiVoice Gateway from an SNMP
manager. After the Reset command is issued, a one-minute timeout (not modifiable) permits
the MultiVoice Gateway to confirm the set request before the unit is reset.
Information held in the Ascend Events Group is erased and its values are initialized when the
MultiVoice Gateway is reset by software or by toggling the power off and on. The SNMP
object sysAbsoluteStartupTime is the time in seconds since January 1, 1990, and is not
modified. To determine whether the MultiVoice Gateway has actually reset, you can retrieve
sysAbsoluteStartupTime and compare this value against the previous poll’s value for
Ascend Events Group variables.
Example of a SNMP security configuration
This example sets the community strings, enforces address security, and prevents write access:
1 Open Ethernet > Mod Config > SNMP Options.
2 Set R/W Comm Enable to Yes.
3 Specify the Read Comm and R/W Comm parameter strings.
4 Set Security to Yes.
5 Specify up to five host addresses in the RD MgrN parameters. Leave the WR MgrN
parameters set to zero to prevent write access.
