Appendix A. Understanding SNMP
Trap
This is an unsolicited message issued by a network device to report an operational anomaly or an alarm condition to the net- work manager.
These messages are typically encased within informational packets and transported over the LAN or WAN (wide area net- work).
TSU 120 SNMP Access
By default, SNMP MIB Browser access to the TSU 120 IP address with the configured community names, accesses the host. The TSU 120 can also act as an SNMP proxy agent for external units. To access MIB variables on externally chained devices, append a period and the Unit ID of the device to the Read and Read/Write community names. For example, if the Read community name configured in the TSU 120 is public, specifying public.3 as the community name in the SNMP MIB Browser allows reading SNMP MIB variables from externally chained unit with a Unit ID of 3.
If the external unit's passcode is not the default, an entry must be added to the Unit Access Table for SNMP MIB access. See the Unit Access Table on page
