NTP-G28 Set Up SNMP
• UDP Port—The default User Datagram Protocol (UDP) port for SNMP is 162. If the node is an ENE
in a SOCKS proxy server network, the UDP port must be set to the GNE’s SNMP relay port, which
is 391.
• Trap Version—Choose either SNMPv1 or SNMPv2. Refer to your NMS documentation to determine
which version to use.

Step 5
Click OK. The node IP address of the node where you provisioned the new trap destination appears in
the Trap Destinations area.
Step 6 Click the node IP address in the Trap Destinations area. Verify the SNMP information that appears in
the Selected Destination list.
Step 7 If you want the SNMP agent to accept SNMP SET requests on certain MIBs, click the Allow SNMP Sets
check box. If this box is not checked, SET requests are rejected.
Step 8 If you want to set up the SNMP proxy feature to allow network management, message reporting, and
performance statistic retrieval across ONS firewalls, click the Enable SNMP Proxy check box located
on the SNMP tab.
Note The ONS firewall proxy feature only operates on nodes running Software Release 4.6 and later.
Using this feature effectively breaches the ONS firewall to exchange management information.
For more information about the SNMP proxy feature, refer to the Cisco ONS 15454 Troubleshooting
Guide or the Cisco ONS 15454 SDH Troubleshooting Guide.
Step 9 Click Apply.
Step 10 If you are setting up SNMP proxies, you can set up to three relays that send SNMP trap error counts back
to NE for each trap destination address:
a. Click the first trap destination IP address. The address and its community name appear in the
Destination fields.
b. Enter up to three SNMP Proxy relay addresses and community names in the fields for Relay A,
Relay B, and Relay C.
Note The community names specified for each relay node must match one of the provisioned
SNMP community names in the NE.
Note The SNMP proxy directs SNMP traps from this node through IpA to IpB to IpC to the trap
destination. Ensure that you enter the IP addresses in the correct order so that this sequence
runs correctly.
