Bridge

Bridge Model 7130CF Series
Accessing SNMP data on the bridge requires the proper
setting of community strings for both the bridge and the
SNMP consumer (NMS device from which SNMP control/
monitoring will take place). For an NMS device to be able to
read SNMP data from the bridge (i.e. ability to issue SNMP
“Get” or “GetNext” requests), at minimum a string must
be placed in the “Read Only Community String” field. This
string acts as a password when trying to read the device’s
information from an NMS. For a network device to be able to
write data to the settable SNMP fields (e.g., ability to issue
SNMP “Set” requests), a private string must be placed in the
“Read/Write Community String” field. An NMS device with
the same Read/Write community string will have the ability to
read and write SNMP data on the bridge.
7.3.1. Supported standard OIDs and Traps
The TZ Centurion Bridge implements the full complement of
SNMP standard “system” (mib-2.1) Object Identifiers (OIDs),
as found in the base internet.mgmt control structure. Many
of these values are set in the SNMP Configuration Stub as
described above. These values represent the general system
information necessary to identify the device on the
SNMP network.
In addition to the basic system information, the TZ Centurion
Bridge implements the minimum standard SNMP traps. They
are as follows:
>
coldStart: Indicates the system has restarted, and a ROM
value has been changed. This indicates that the device
array has been reset or modified by use of the “reset”
switch on the back of the bridge.
>
warmStart: Indicates the bridge has gone through a
normal maintenance reboot or user initiated power
cycle. No changes were made to the internal ROM,
and execution has been resumed normally.
>
authenticationFailure: Indicates a network device has
attempted to access (Get) SNMP information on the
bridge without proper community authentication.
7.3.2 MIB file and Enterprise specific OIDs
A full complement of device specific OIDs have been
created to handle control of TZ specific parameters. These
parameters are described in the TZ-(xx).mib, included on the
CD that came in the box, or which can be downloaded from
the following link: http://ixp.tz.net/tz-centurion. The TZ mib
file is updated to describe additional TZ devices periodically,
but this document will only go over the centurionBridge
section (OID: private.enterprises.tz.1).
The Centurion Bridge OIDs are separated out into three
sections: product, setup, devices. Each section and
corresponding database entries are described below. For
a quick reference, comments have been entered into the
MIB file to describe each data point along with setting and
translation hints.
7.3.2.1 Product Section (OID: .tz.centurionBridge(1).1)
The “product” section of the mib file describes specific property values of the product.
