Extended Fabrics Supports the reliable, high-speed connectivity of SilkWorm switches over dark fiber
or Dense Wave Division Multiplexing (DWDM) equipment at distances up to 500 km
to enhance business continuance operations.
Fabric Watch Continuously monitors SAN fabrics for potential faults based on thresholds set for a
variety of SAN fabric elements and events—automatically alerting administrators to
potential problems before they become costly failures.
ISL Trunking Optimizes the performance and availability of SAN fabrics while simplifying ISL
management. Two 4 Gbit/sec SilkWorm switches can automatically group up to eight
ISLs into a single logical “trunk” with a total throughput of up to
32 Gbit/sec.
Advanced ZoningAutomatically groups SAN fabric-connected devices into logical zones that restrict
access to “member” devices in the zone. Advanced Zoning uses hardware
enforcement at both the port and WWN level to provide more robust data protection.
Secure Fabric OSProvides a comprehensive security solution to help protect mission-critical data. Key
features include centralized policy-based security management, management data
encryption, and authentication to create a fabric-wide trusted environment with
control over all levels of fabric access and communication.
FICON®CUP Enables IBM host-based management programs to manage FICON fabric switches
in-band by sending commands to the Fabric OS emulated control device.

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.
This chapter discusses the following:
•“Understanding SNMP Basics,” next
•“Loading Brocade MIBs” on page 1-5
•“SilkWorm 7500 / FR4-18i and Brocade MIBs” on page 1-8
•“Firmware Upgrades and Enabled Traps” on page 1-8
•“Fabric OS Commands for Configuring SNMP” on page 1-8
Understanding SNMP Basics
Every Brocade SilkWorm switch carries an agent and management information base (MIB), as shown
in Figure 1-1. The agent accesses information about a device and makes it available to an SNMP
network management station.
Figure 1-1 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 (see Figure 1-2). 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 1-2 SNMP Query
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.
Figure 1-3 SNMP Trap
The agent can receive queries from one or more management stations and can send traps to up to six
management stations.
Understanding 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.
