This online reference provides instructions for accessing and downloading the Cisco Management Information Base (MIB) files.
This section contains the following information:
You can access the Cisco MIB files in any of the following ways:
http//www.cisco.com
Use these steps to access the Cisco public MIBs using FTP:
Step 1 Use FTP to access the server ftp.cisco.com.
Step 2 Log in with the username anonymous.
Step 3 Enter your e-mail name when prompted for the password.
Step 4 At the ftp> prompt, change your directory to reflect the following path:
where switch is the name of the switch you want, such as wsc5000 for the Catalyst 5000.
Step 5 Enter the get supportlist.txt command to obtain the supportlist.txt file containing a list of MIBs the switch supports.
Step 6 Enter the get command to retrieve the desired MIB files from the v1/ or v2/ directories.
CCO serves a wide variety of users through two interfaces that are updated and enhanced simultaneously---a character-based version and a multimedia version, which both reside on the WWW. The character-based CCO (called "CCO Classic") supports Zmodem, Kermit, Xmodem, FTP, Internet e-mail, and fax download options, and allows quick access to information over lower bandwidths. The WWW version of CCO provides richly formatted documents with photographs, figures, graphics, and video, as well as hyperlinks to related information.
You can access CCO in the following ways:
http://www.cisco.com.
cco.cisco.com (198.92.32.130).

To access the information that certain MIB variables support, you must enter either an Interface Index (IF-INDEX) or Bridge Identifier (BridgeID) value as an instance identifier. Use the following links for descriptions on how to access these types of values for use with MIBs mentioned previously:
To find the module number and port number to which an IF-INDEX is mapped, read the IfName in the MIB object of the Interface Extension MIB (RFC 1573). Use this method to find the IF-INDEX when you are accessing any of the variables in the Cisco Discovery Protocol (CDP) MIB that require an IF-INDEX for a variable instance identifier (such as "CDP neighbors").
For example, the Catalyst 5000 series switch Group Switching Ethernet module has 12 ports in each of its four switched, repeated segments. To gather statistical information about one of these segments using the Interface Extension MIB (RFC 1573) or CDP MIB, use the IF-INDEX of the first port of the segment (port 1, 13, 25, or 37) as the variable instance identifier.
Standard remote monitoring (RMON, RFC 1757) supports nine types of monitoring groups. Catalyst 5000 series switches support four of these groups: statistics, history, alarms, and events. Any RMON-compliant manager can obtain and display information from these groups. For example, the Cisco TrafficDirector application provides a simple, point-and-click method of obtaining the information. Refer to the TrafficDirector Windows User Guide or TrafficDirector UNIX User Guide for details about TrafficDirector.
Collecting RMON information requires you to create TrafficDirector software agents. These agents consist of an IP address and an interface index (IF-INDEX) for the port about which information is to be collected. For instructions about how to display the IF-INDEX and the port number to which it is mapped, refer to "Displaying the IF-INDEX Using SunNet Manager" and "Displaying the IF-INDEX Using HP Openview." To gather statistical information using the Interface Extension MIB (RFC 1573) or CDP MIB, use the IF-INDEX of the first port of the segment (port 1, 13, 25, or 37) as the variable instance identifier.
For the Catalyst 5000, the Bridge MIB (RFC 1493) contains a bridge port number for each Group Switching Ethernet module segment. Query the portCrossIndex.mod_num.port_num MIB object in the CISCO-STACK-MIB to find the BridgeID. The mod_num is the module number in Catalyst 5000 series switches, and the port_num is the first port in each Group Switching Ethernet module segment (that is, port 1, 13, 25, or 37).
To display Bridge MIB information for different VLANs, change the SNMP community string to append @vlan_num to the configured SNMP community string. The vlan_num is the VLAN number.
To access the different segments of the Group Switching Ethernet module using the SNMP-REPEATER-MIB (RFC 1516), change the SNMP community string of your SNMP application that references Catalyst 5000 series switches to the following syntax:
community_string@mod_num/port_num
The community_string represents the name of the SNMP community (the defaults are Public for read-only permission, private for read-write permission, and secret for read-write-all permission). The mod_num is the module number in Catalyst 5000 series switches and the port_num is the first port of each segment. For segment one, use port 1; for segment two, use port 13; for segment three, use port 25; and for segment four, use port 37.
This section contains instructions on how to display the IF-INDIEX using the following methods:
Display the IF-INDEX and port number of a switch using SunNet Manager by performing the following steps:
Step 1 Download the following files from ftp.cisco.com:
/pub/mibs/schema/IF-MIB.schema
/pub/mibs/oid/IF-MIB.oid.
Step 2 Copy these files to your SNMP agents directory, which is typically located in $SNMHOME/agents.
Step 3 Reinitialize SunNet Manager using the following command:
$SNMHOME/bin/snm -i
Step 4 If a switch icon you are interested in monitoring is present in your network application topology map, highlight it and select IF-MIB from the properties sheet list. If a switch icon is not present, create a new object to represent the switch in your network before highlighting its icon and selecting IF-MIB from the properties sheet list.
Step 5 Select the following on the device-specific menu:
Quick Dump, IF-MIB, and ifXTable.
Output similar to the following will be displayed. The IF-INDEX is listed under the column heading "KEY" in the first column of the output.
Apr 12 13:48:39 1996 [ 172.20.24.188 ] : Quick Dump: IF-MIB.ifXTable
KEY ifName ifInMulticastPkts ifInBroadcastPkts...
1 sc0 0 0
2 sl0 0 0
3 1/1 0 0
4 1/2 0 0
5 2/1 0 0
6 2/2 0 0
7 2/3 0 0
8 2/4 0 0
9 2/5 0 0
10 2/6 0 0
11 2/7 0 0

13 2/9 0 0
14 2/10 0 0
15 2/11 0 0
16 2/12 0 0
Step 6 Choose the key which corresponds to the module or port to monitor.
Display the IF-INDEX and port number of a switch using HP Openview by performing the following steps:
Step 1 Download the following file from ftp.cisco.com:
/ftp/pub/mibs/V2/IF-MIB.my
Step 2 Copy this MIB file to your OpenView MIBs directory, which is typically located in the directory path:
/usr/OV/snmp_mibs
Step 3 Rename the file rfc1573.mib to rfc1573-INTERFACES.
Step 4 Select the following from the HP Openview main menu:
Options, Load/Unload MIBs:SNMP.
Step 5 Click Load. Choose the filename rfc1573-INTERFACES, and click OK.
Step 6 Select the following from the HP Openview main menu:
Monitor, MIB Values, Browse MIB:SNMP
Step 7 Type a device name or IP address into the form and then click MIB Object ID.
