Loading Brocade MIBs

Traps

An unsolicited message that comes to the management station from the SNMP agent on the device is

called a trap. Brocade switches send traps out on UDP port 162 only.

For more information on Brocade MIB Traps refer to “sw Traps” on page 5-9.

Loading Brocade MIBs

The Brocade MIB is a set of variables that are private extensions to the Internet standard MIB-II. The

MIB-II standard is documented in Request for Comment (RFC) 1213, Management Information Base

for Network Management of TCP/IP-based Internets: MIB-II. The Brocade agents support many other

Internet-standard MIBs. These standard MIBs are defined in RFC publications. To find specific MIB

information, examine the Brocade propriety MIB structure and the standard RFC MIBs supported by

Brocade.

This section describes the requirements and dependencies when loading MIBs. Sections include:

• “Before Loading MIBs,” next

• “MIB Loading Order” on page 1-4

Before Loading MIBs

Before loading Brocade MIB files, ensure you have the correct version of SNMP for your Fabric OS

version (refer to Table 1-1).

MIB Loading Order

Many MIBs use definitions that are defined in other MIBs. These definitions are listed in the IMPORTS

sections near the top of the MIB. When loading the Brocade MIBs, see Figure 1-6 to ensure any MIB

dependencies are loading in the correct order.
