4 Configuring the NCL1170
22 APCD–NC006–A
4.3.2 Setting the DHCP Relay Configuration
When the NCL1170 is in routing mode, you can optionally enable Dynamic Host Control
Protocol (DHCP) relay which makes the NCL1170 aware of the protocol for DHCP traffic and
forwards the responses to the designated DHCP server.
NOTE: When the NCL1170 is operating in bridging mode, DHCP Relay is
transparent, and therefore, not an available option.
You can specify up to five DHCP servers in the NCL1170 configuration.
1. At the
NCL1170>
prompt, type
<dhcp mode relay>
to enable DHCP Relay in the
device.
2. To add a DHCP server, type
<dhcp relay add ip_address >
where
ip_address
is the IP Address for the DHCP Server available for the NCL1170 to
forward and receive DHCP traffic.
3. At the
NCL1170>
prompt, type
<save>
to transfer the settings to memory.
NOTE: To remove a DHCP server, type
<dhcp relay delete
ip_address >
. To disable DHCP Relay, type
<dhcp mode
none>.
4.3.3 Setting the SNMP Configuration
Simple Network Management Protocol (SNMP) enables a network management station to
remotely monitor and control network devices incorporating an SNMP agent.
SNMP allows you to look at SNMP variables using READ communities, and to set SNMP
variables using WRITE communities. Communities are optional on the NCL1170, but it can
support a maximum of five communities. An NCL1170 is 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 has taken 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 NCL1170 implements SNMPv2c and includes a number of standard SNMP MIBs:
• RFC1157 (MIB-Il)
• RFC1493 (bridging)
• an NCL1170-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 NCL1170 SNMP agent and to specify a server IP address to which trap
messages are sent.
