Cisco Client MIBs Loading
Instructions
Overview
Introduction
Client MIBs have been developed for Cisco® set-tops so they can be managed
with an SNMP-based Network Management System (NMS).
Note: The MIB files are available on request. Please contact your Cisco
representative who will open a Technical Support inquiry, authenticate the
request, and provide the MIBs. This process has been put in place for security
purposes to ensure MIB details are properly distributed.
Once you have obtained the MIB files, you can use the procedure in this
document to download them to the DNCS, from where you can load the MIBs
onto your NMS.
Below are essential notes about the Cisco Client MIBs.
Notes:
 Client MIBs were developed in accordance with RFC 1901 and RFC 2578 and
are compliant with SNMPv2c and SMIv2, respectively.
 Client SNMP agents are default-enabled and receive requests on UDP port
161, the well known snmp port.
 There are no traps for Cisco set-tops.
 Client MIB documentation is provided in the form of MIB and OID
descriptions that are embedded in the MIBs. The information is normally
accessed using a MIB browser. An example SNMP walk that was captured in a
text file is available for reading the MIB and OID descriptions without a MIB
browser. See Example SNMP Walk (on page 4).
Overview

Downloading the Client MIB Files onto the DNCS
Downloading the Client MIB Files onto the DNCS
The Client MIB files and support files are compressed into a single tarball (rtn-compmibs.tar.gz) and distributed via CD or FTP. Use this procedure to untar the MIB files
onto the DNCS and change the MIBDIRs variable.
1
Open an xterm window on the DNCS.
2
Type cd /export/home/dncs and press Enter to change to the dncs home
directory.
3
Untar RTN-STBmibs.tar, which is contained in the tarball.
This will create a .snmp/mibs directory, extract the MIB files, and add a
snmp.conf file.
4
Type export MIBDIRS=/export/home/dncs/.snmp/mibs and press Enter to
change the MIBDIRs variable to this mib path.
5
Type snmpwalk <STB ip address> system and press Enter to verify access to
the Client MIBs.
Once the Client MIB files are on the DNCS, they are properly staged for loading onto
your NMS.

Example SNMP Walk
Example SNMP Walk
A second tarball (rtn-mib-example.tar.gz) is supplied with the Client MIB tarball that
contains an example SNMP walk of the Client MIBs. This is a text file that can be
accessed without a MIB browser and is provided for your convenience. Use this file
for reading the MIB and OID descriptions so you can see what parameters can be
managed on your Cisco set-tops.
You can access the example SNMP walk text file by untarring rtn-mibexample.tar.gz on any system that supports tarball extraction.
