Chapter 3 Configuring the NCL1135
20 APCD–NC003–1.0
Setting the SNMP Configuration
SNMP enables a network management station to monitor, control, and remotely configure
network devices called agents.
SNMP allows you to look at SNMP variables using READ communities, and to set SNMP
variables using WRITE communities. Communities are optional on the NCL1135, but it can
support a maximum of five communities. An NCL1135 comes factory-configured with two
communities, a READ community called public and a WRITE community called private.
SNMP also provides a mechanism called trap, which notifies a network management station
that a significant event took place. A significant event can be an interface going down or
coming up, a unit performing a cold or warm start, or an authentication failure. Refer to RFC
1157 for details.
Associated with SNMP are Management Information Bases (MIBs). These specify a collection
of management information available from the agent. This information can be controlled and
monitored from a network management station.
The NCL1135 implements SNMPv2c and includes a number of standard SNMP MIBs:
• RFC1157 (MIB-Il)
• RFC1493 (bridging)
• an NCL1135-specific MIB
WaveRider MIBs can be downloaded from the technical support page at www.waverider.com.
The following procedure describes how to configure standard SNMP communities for read/
write access to the NCL1135 SNMP agent and to specify a server IP address to which trap
messages are sent.
1. At the NCL1135> prompt, type <snmp> to display the current SNMP settings for the
NCL1135.
2. To add a new community, type <snmp community add
community
READ|WRITE> where
community is the name of the community and READ|WRITE
is the community type. You can have a maximum of five communities.
3. If a community is not set up the way you want it, delete it by typing
<snmp community del
community READ|WRITE> where community is the
name of the community and READ|WRITE is the community type.
4. At the NCL1135> prompt, type <snmp location
location > to change the
geographical location of the NCL1135.
5. Type <snmp contact
contact > to change the contact name for the NCL1135. The
contact can be a name and phone number, a URL, or an email address.
6. To add a trap server to the NCL1135 configuration, type <snmp trap add
aaa.bbb.ccc.ddd community> where aaa.bbb.ccc.ddd is the IP address of
the trap server and
community is the name of the community on the trap server.
7. To delete a trap server from the NCL1135 configuration, type <snmp trap del
aaa.bbb.ccc.ddd community> where aaa.bbb.ccc.ddd is the IP address of
the trap server and
community is the name of the community on the trap server.
8. At the NCL1135> prompt, type <write> to save the settings to memory.
