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.
For 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 Ac-
cess Table for SNMP MIB access. How-
ever, SNMP traps for the unit can be
forwarded without the entry.
See Unit Access Table on page 8-1 , for
more information.
