OPTIONAL BROCADE FEATURES
Optional Brocade features include:
Advanced Performance Monitoring
Enables more effective end-to-end SAN performance analysis to enhance performance tuning,
increase productivity, optimize resource utilization, and reduce costs.

Fabric OS MIB Reference xv
53-1000602-01
Extended Fabrics
Supports the reliable, high-speed connectivity of Brocade 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 Brocade switches can automatically group up to eight ISLs into a single logical “trunk”
with a total throughput of up to
32 Gbit/sec.
Advanced Zoning
Automatically 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 OS
Provides 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.
FCIP Support
The FCIP Tunneling Service is an optional feature that enables you to use the Fibre Channel tunnels
to connect SANs over IP-based networks. An FCIP tunnel transports data between a pair of Fibre
Channel switches, and can have more than one TCP connection between the pair of IP nodes.
However, from the Fibre Channel fabric point of view, the FCIP tunnel is just a connection.
iSCSI Support
iSCSI (Internet-SCSI) is a transport carrier of the SCSI protocol over IP. The FC4-16IP embedded
switch in a SilkWorm 48000 director functions as an iSCSI target gateway. A Fibre Channel virtual
initiator is created behind each iSCSI port running as a proxy Fibre

Getting Technical Help
Contact your switch supplier for hardware, firmware, and software support, including product
repairs and part ordering. To expedite your call, have the following information immediately
available:
1. General Information
-Technical Support contract number, if applicable
-Switch model
-Switch operating system version
-Error numbers and messages received
-supportSave command output
-Detailed description of the problem, including the switch or fabric behavior immediately
following the problem, and specific questions
-Description of any troubleshooting steps already performed and the results
-Serial console and Telnet session logs
-Syslog message logs
2. Switch Serial Number
The switch serial number and corresponding bar code are provided on the serial number label,
as shown here:

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.

•Fabric OS Commands for Configuring SNMP . . . . . . 10
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 =
No 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

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 (see 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. See “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.
