Note The ONS firewall proxy feature only operates on nodes running releases 4.6 and later. Using this
information effectively breaches the ONS firewall to exchange management information.
For more information about the SNMP proxy feature, refer to the “SNMP” chapter of the
Cisco ONS 15454 SDH Reference Manual.
Step 8 Click Apply.
Step 9 If you are setting up SNMP proxies, you can set up to three relays for each trap address to convey SNMP
traps from the NE to the NMS. To do this, complete the following substeps:
a. Click the first trap destination IP address. The address and its community name appear in the
Destination fields.
b. If the node you are logged into is an ENE, set the Relay A address to the GNE and type its
community name in the community field. If there are NEs between the GNE and ENE, you can enter
up to two SNMP proxy relay addresses and community names in the fields for Relay and Relay C.
When doing this, consult the following guidelines:
• If the NE is directly connected to the GNE, enter the address and community name of the GNE
for Relay A.
• If this NE is connected to the GNE through other NEs, enter the address and community name
of the GNE for Relay A and the address and community name of NE 1 for Relay B and NE 2
for Relay C.
The SNMP proxy directs SNMP traps in the following general order:
ENE > RELAY A > RELAY B > RELAY C > NMS
For example:
• If there is are 0 intermediate relays, the order is ENE > RELAY A (GNE) > NMS
• If there is 1 intermediate relay, the order is ENE > RELAY A (NE 1) > RELAY B (GNE) > NMS
• If there is are 0 intermediate relays, the order is ENE > RELAY A (NE 1) > RELAY B (NE 2)
> RELAY C (GNE) > NMS
Step 10 Click Apply.
Step 11 Repeat Step 2 through Step 10 for all NEs between the GNE and ENE.
Step 12 Return to your originating procedure (NTP).
