TDU 120e SNMP Access
By default, SNMP MIB Browser access to the TDU 120e IP
address with the configured community names, accesses
the host. The TDU 120e 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.
Example:
If... Then...
The Read community name
configured in the TDU 120e is
public
,
Specify
public.3
as the community
name in the SNMP MIB Browser.
This allows reading SNMP MIB
variables from externally chained
unit 3.
The external unit's passcode is
not the default, An entry must be added to the Unit
Access Table for SNMP MIB access.
However, SNMP traps for the unit
can be forwarded without the entry.
See Unit Access Table on page 8-2 ,
for more information.
