Understanding Brocade SNMP
The Simple Network Management Protocol (SNMP) is an industry-standard method of monitoring
and managing network devices. This protocol promotes interoperability, because SNMP-capable
systems must adhere to a common set of framework and language rules.
Understanding the components of SNMP makes it possible to use third-party tools to view, browse,
and manipulate Brocade switch variables (MIBs) remotely as well as to set up an enterprise-level
management process. Every Brocade switch and director supports SNMP.

Setting the SNMP Security Level
Recipients for SNMP traps are restricted according to security levels. Security levels are selected
and set for a switch using the snmpconfig --set seclevel command. To select and set SNMP security
levels, issue the command snmpconfig --set seclevel after having logged in to the switch as admin.
The following example sets the SNMP security level to 1(authentication only). This setting
allows all snmpv1 users to perform GET and SET operations on mibs, but creates an exception
for snmpv3 users that do not have authentication and privacy privileges (noAuthnoPriv).
switch:admin> snmpconfig --set seclevel
Select SNMP Security Level
(0 = No security, 1 = Authentication only, 2 = Authentication and Privacy, 3 =
sxNo Access): (0..3) [0]
Select SNMP SET Security Level
(0 = No security, 1 = Authentication only, 2 = Authentication and Privacy, 3 =
No Access): (0..3) [0]

Understanding SNMP Basics
Every Brocade switch carries an agent and management information base (MIB), as shown in
Figure 1. The agent accesses information about a device and makes it available to an SNMP
network management station.
FIGURE 1 SNMP Structure
When active, the management station can get information or set information when it queries an
agent. SNMP commands, such as get, set, getnext, setnext, and getresponse, are sent from the
management station, and the agent replies once the value is obtained or modified ( Figure 2).
Agents use variables to report such data as the number of bytes and packets in and out of the
device, or the number of broadcast messages sent and received. These variables are also known
as managed objects. All managed objects are contained in the MIB.
FIGURE 2 SNMP Query
The management station can also receive traps, unsolicited messages from the switch agent if an
unusual event occurs. Refer to “Understanding SNMP Traps” on page 4 for more information.
FIGURE 3 SNMP Trap
The agent can receive queries from one or more management stations and can send traps to up to
six management stations.

Understanding SNMP Basics 1
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
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.
FIGURE 4 Brocade MIB Tree Location
Use a MIB browser to access the MIB variables: all MIB browsers perform queries and load MIBs.
Since different vendors vary the information in their private enterprise MIBs, it is necessary to verify
their information. The Fibre Channel MIB standards dictate that certain information be included in
all MIBs: it is the vendors’ responsibility to follow the standards. The standards are:
•FibreAlliance (FA) MIB: Brocade supports version 3.0.
•Fabric Element (FE) MIB: accepted by the Internet Engineering Task Force (IETF).

Brocade supports FE_RCF2837.mib under the MIB-II branch in Fabric OS v6.1.0, v6.0.0, v4.x,
v3.2.0, and v3.1.x and the experimental version, FE_EXP.mib, in Fabric OS v2.6.x and 3.0.x.
This latest version of the FE MIB references the FRAMEWORK.MIB and, based on the MIB
browser, it is necessary to load this MIB before the FE.MIB. Refer to “Loading Brocade MIBs”
on page 6 for more information.
Once loaded, the MAX-ACCESS provides access levels between the agent and management station.
The access levels are as follows:
•not-accessible
You cannot read or write to this variable.
•read-create
Specifies a tabular object that can be read, modified, or created as a new row in a table.
•read-only - Public
You can only monitor information.
•read-write - Private
You can read or modify this variable.
Understanding SNMP 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 and to any configured
port. In order to receive traps, the management station IP address and severity level must be
configured on the switch. Up to six trap recipients can be configured using Web Tools or the
snmpConfig command. You can define a different message severity level for each recipient so that
some recipients receive all trap messages and others receive only the most critical.
There are two main MIB trap choices:
•FibreAlliance MIB trap - Associated with the Fibre Alliance MIB (FA-MIB), this MIB manages SAN
switches and devices from any company that complies with Fibre Alliance specifications.
•Brocade-specific MIB trap - Associated with the Brocade-specific Brocade MIB (SW-MIB),
manages Brocade switches only.
There is some overlap in the functionality of these MIBs. If you enable both SW-MIB and FA-MIB
traps, you could receive duplicate messages for the switch events that trigger the trap.
You can also use these additional MIBs and their associated traps: HA-MIB; FICON-MIB; and
SW-EXTTRA. You can use the snmpConfig command to disable the FA-MIB, HA-MIB, FICON-MIB, and
SW_EXTTRA; but neither the SW-MIB or the FE-MIB can be disabled.
An event trap (swEventTrap, connUnitEventTrap, or swFabricWatchTrap) is basically an error
message (errShow output) that is SNMP-formatted and delivered.
FA Traps
Consider enabling the FA traps if you want to use SNMP to monitor multiple connectivity units,
including Brocade switches.
The switchStatusPolicySet command determines the FA-TRAP switch status-related outputs:
•connUnitStatusChange
•connUnitSensorStatusChange
