3.5.1 Prerequisites for Adding NEs

To add entries to the SNMP Community String table:

Step 1 In the Domain Explorer window, choose Administration > ONS 155XX >

ONS 155XX SNMP Settings Table. The SNMP Community String table opens. Table 3-5provides descriptions.

Step 2 If the IP address of the NE is not already in the table, choose Edit > Add. The Add SNMP Parameters dialog box opens.

Note The SNMP Community String table contains a default entry for all ONS 15501, ONS 15530, and ONS 15540 NEs that are configured with the default community string.

Step 3 Add the IP address in the Target field; the IP addresses for all ONS 15501, ONS 15530, and ONS 15540 NEs must be specified in this table.

Step 4 Make sure that the correct community strings for each ONS 15501, ONS 15530, and ONS 15540 are in the table under the Read/Write field.

Step 5 (Optional) Configure the timeout and retry.

Step 6 Click OK.

Field Descriptions for the SNMP Community String Table

 

 

Field

Description

 

 

Target

IP address of the NE or range of NEs to which you are assigning the community strings in this entry. You can

 

enter a specific IP address, wildcard characters (*) in any portion of the address, and ranges. For example:

 

• 172.*.*.*

 

• 172.20.[4-55].*

 

You can add a combination of general and specific entries, but the community strings are read from most

 

specific to least specific. Wildcard characters cannot appear in ranges.

 

 

Read/Write

Community string that allows read/write access to the NEs in the entry.

 

 

Retry

Number of times the server attempts to communicate with the device before reporting that the device has

 

timed out. By default, the server makes one retry. You can specify from 0 to 5 retries.

 

 

Timeout

Length of time the server waits for a response from the device before performing the first retry. The Cisco

 

default timeout is 15 seconds. You can specify from 0 to 60 seconds.

 

 

Note

• You can change SNMP Community String table entries at any time to match the community strings

 

set on NEs. Routine community string changes take effect after the next health poll cycle or after a

 

rediscovery. For information about the health poll or about discovery, see Chapter 4, “Maintaining

 

an Efficient Network.”

 

• You can modify SNMP parameters. In the SNMP Community String table, choose Edit > Modify

 

to modify the SNMP parameters in the Modify SNMP Parameters window.

 

• You can delete SNMP parameters. In the SNMP Community String table, choose Edit > Delete to

 

delete SNMP parameters.
