defaults to public. NMSs
using this community name have Read access for all sup-
ported MIB objects but do not have the ability to change
MIB objects. This value must be set to the same value on
both the TDU 120e and the NMS (OpenView®, etc.) in or-
der for the NMS to have Read access to MIBs supported
by the TDU 120e. This value must be a text string of 16
characters or less.
SNMP Read/Write Community
SNMP NMS using this community name have full Read/
Write access to all supported MIB objects (defaults to pri-
vate). This setting must be the same value on both the
TDU 120e and the NMS in order for the NMS to have
Read/Write access to MIBS supported by the TDU 120e.
This value must be a text string that is 16 characters or
less.
SNMP Trap Community
This community name is used for all SNMP traps for-
warded by the TDU 120e. Traps received from daisy-
chained units have a period and the unit ID appended to
the trap community name.
Host 1 Trap IP Address
The first of four entries for SNMP trap destination
addresses. The TDU 120e forwards all SNMP traps to the
IP address specified in this entry. If the address is set to
the default value of 0.0.0.0, no traps are forwarded for
this particular value.
To access other units external to the TDU 120e (proxied units) using an
SNMP MIB browser, append a period and the unit ID of the external
device to the Read Only and Read/Write community name used in the
MIB Browser, for example public.4. See Appendix A, Understanding
SNMP, for more information.
