This command is used to configure the IP address of the SNMP trap manager. Since
traps are unsolicited alarms, an agent can take the initiative to inform the manager of the
occurrence of a predefined condition. Typical conditions include the cold-start or warm-
start of equipment and a link-down or link-up condition.
A single and multiple SNMP managers can access the unit. However, only one SNMP
manager can be defined as the trap manager. As a result of this command, all traps will
be directed to the chosen trap manager.
The ipaddr field defines the IP address of the SNMP manager to which the traps are to
be sent.
The port field indicates the UDP port on that SNMP manager and defaults to the
standard value of 162.
Any combination of closed user group membership may be assigned to the SNMP
interface using the parameter of cug=[+|-]<CUG Number>. The closed user group
membership is displayed on the “verify module” output. Packets which have failed the
SNMP Closed User Group Test are discarded. An alarm is not presented, but the failure
is counted. The number may be displayed with the “dmeas mod” command.
The unit allows setting of an SNMP community in addition to the public community. The
public community is recognized when the
[ PUBLIC=YES ] option is selected.
Recognition of the public community is the default operation. When [ PUBLIC=NO ] is
selected, the public community is not recognized.
The xxxx allows setting of an SNMP community in addition to the public community.
When configured, the xxxx will respond to SNMP manager requests in that community.
The xxxx will always respond to a request in the public community. The settable SNMP
community is configured with the
[ COMM=”Double Quoted String” | NONE ] option. The
community may be in any case. The double quote encapsulation is not part of the
community string. The settable community may be cleared by setting it to the keyword
NONE .
The MIB-II variables sysName, sysContact, and sysLocation may be initialized from the
xxxx non-volatile database using the SNMP command. These variables are volatile in
that they may be over-written by an SNMP manager. However, any change made by the
SNMP manager will not impact the xxxx non-volatile database. Setting the value to
NONE will clear the entries in the xxxx non-volatile database. Each field may be of 31
characters or less. The double quote encapsulation is not part of the respective variable.
Any of the variables may be cleared by setting it to the keyword
NONE .
