3.5.1 Prerequisites for Adding NEs

–Trap port: 162

–Version: v1

–Community string: Same as on the GNE

Note If there is a direct connection from the ENE to GNE, it becomes the Relay A NE. If there are intermediate NEs between the ENE and GNE, these NEs must be specified as the relays. The community strings should be the same on all the NEs, including the relay NEs.

2.SNMP v2 uses the following configurations on GNEs and ENEs for traps: GNE: Same as for SNMP v1

ENE: Same as for SNMP v2 on option b

3.5.1.4Prerequisites for Adding ONS 15501, ONS 15530, and ONS 15540 NEs

Before adding ONS 15501, ONS 15530, and ONS 15540 NEs to CTM, verify that the NEs are properly set up. You can perform most of the setup by using the NE CLI.

When adding NEs to the network, first add information to the SNMP Community String table; then, add one NE (in the Add New NE wizard) for each group of interconnected ONS 155xx NEs. This NE becomes the starting point for automatically discovering the other NEs. Immediately after you add this NE, the information in the SNMP Community String table is used to discover all other ONS 155xx NEs in the group.

The examples given in this section are provided for illustration purposes only. Refer to the relevant hardware documentation for detailed command information.

3.5.1.4.1 Hostnames and IP Addresses (Required)

All NEs must be configured with unique hostnames and IP addresses.

3.5.1.4.2 SNMP Community Strings (Required)

NEs must be reachable through SNMP. Use the snmp-server host command to add the CTM server to the list of SNMP trap destinations on each NE. Use the snmp-server enable traps command to enable trap generation for events and alarms.

Note Only SNMP version 2c traps are supported.

Each NE must have an entry in the SNMP Community String table, which is the basis for ONS 155xx autodiscovery and must contain valid community strings for each ONS 155xx in the network. Autodiscovery relies on Cisco Discovery Protocol (CDP) or on the configuring topology on the device.

There is one default entry in this table, which provides SNMP access to all ONS 155xx NEs in the network, provided you are using the default community strings.

You can add, modify and delete entries in this table. All fields in an entry must be filled in; blank fields are not permitted.
