The management station can also receive traps, unsolicited messages from the switch agent if an
unusual event occurs. See “Understanding SNMP Traps” on page 5 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 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
