Parameters for unconditional SNMP trap logging

SnmpTrapLogging (SNMP Trap Logging)

Enable the NetScaler appliance to log any SNMP traps messages (for those respective SNMP alarms in which logging is enabled) even when no trap listeners are configured. Possible Values: ENABLED, DISABLED. Default: DISABLED.

Configuring the NetScaler for SNMP v1 and v2 Queries

You can query the NetScaler SNMP agent for system-specific information from a remote device called SNMP managers. The agent then searches the management information base (MIB) for the data requested and sends the data to the SNMP manager.

The following types of SNMP v1 and v2 queries are supported by the SNMP agent:

wGET

wGET NEXT

wALL

wGET BULK

You can create strings called community strings and associate each of these to query types. You can associate one or more community strings to each query type. Community string are passwords and used to authenticate SNMP queries from SNMP managers.

For example, if you associate two community strings, such as abc and bcd, to the query type GET NEXT, the SNMP agent on the NetScaler appliance considers only those GET NEXT SNMP query packets that contain abc or bcd as the community string.

Specifying an SNMP Manager

You must configure the NetScaler appliance to allow the appropriate SNMP managers to query it. You must also provide the SNMP manager with the required NetScaler-specific information. You can add up to a maximum of 100 SNMP managers or networks.

For an IPv4 SNMP manager you can specify a host name instead of the manager's IP address. If you do so, you must add a DNS name server that resolves the host name of
