The management station can also receive traps, unsolicited messages from the switch agent if an
unusual event occurs. See “Understanding SNMP Traps” on page 1-4 for more information.

The agent can receive queries from one or more management stations and can send traps to up to six
management stations.
Understanding MIBs
The management information base (MIB) is a database of monitored and managed information on a
device, in this case a Brocade switch. The MIB structure can be represented by a tree hierarchy. The
root splits into three main branches: International Organization for Standardization (ISO), Consultative
Committee for International Telegraph and Telephone (CCITT), and joint ISO/CCITT. These branches
have short text strings and integers (OIDs) to identify them. Text strings describe object names, while
integers allow software to create compact, encoded representations of the names.
Each MIB variable is assigned an object identifier (OID). The OID is the sequence of numeric labels on
the nodes along a path from the root to the object. For example, as shown in Figure 1-4, the Brocade
SW.MIB OID is:
1.3.6.1.4.1.1588
The corresponding name is:
iso.org.dod.internet.private.enterprise.bsci
The other branches are part of the standard MIBs, and the portions relevant to configuring SNMP on a
Brocade switch are referenced in the remainder of this reference.
