Using Passive FTP to Access and Download the MIB Files
To access MIB files using passive FTP, you must know the names of the MIB files that you want to
download. See the
page 7
assume that your passive FTP utility has UNIX-like commands.
To download MIB files with passive FTP, follow these steps:
Access ftp.cisco.com using passive FTP.
Step 1
Log in with your Cisco.com username and password, or as anonymous, with your e-mail address.
Step 2
Enter cd /pub/mibs/v2/ to change directories.
Step 3
Use the get command to copy the desired files to your local system.
Step 4
Use the quit command to exit passive FTP.
Step 5
Understanding the ENTITY-MIB and Extensions
The ENTITY-MIB provides basic management and identification of physical and logical entities within
a network switch. Cisco NX-OS support for the ENTITY-MIB focuses on the physical entities within a
switch. This MIB provides details on each module, power supply, and fan tray within a switch chassis.
It gives enough information to correctly map the containment of these entities within the switch.
Cisco has developed a number of private extensions to the ENTITY-MIB to provide more details for
these physical entities. Each MIB extensions shares the common index value, entPhysicalIndex, which
allows the management application developer to link information across multiple MIBs.
