Displaying whether Track Changes is Enabled
To display the status of the track changes feature:
1. Login to the switch as the admin user.
2. At the command line enter the following command:
trackChangesShow
The status of the track changes feature is displayed as either on or off. This also displays
whether the track changes feature is configured to send SNMP traps. For example:
switch:admin> trackchangesshow
Track changes status: ON
Track changes generate SNMP-TRAP: NO
Configuring a Static Route Between Two Ports
To configure a static route between two ports:
1. Login to the switch as the admin user.
2. At the command line enter the following command:
uRouteConfig port, domain, outputport
where port is the port to be statically rout ed; can be either an F_po rt or an E_po rt., domain
is the domain ID of the specified target switch, and outputport is the output port where
traffic is to be forwarded.
After this command is issued, and if outputport is a usable port, all frames coming in fr om
a specified port addressed to the specified domain are routed through the specified
outputport.
If the outputport is not usable, the routing assignment is not affected. When
outputport becomes usable the static route assignment for the port is enforced.
Note: Using static routes can affect load sharing. If a large number of routes are statically
configured to the same output port, the ability of the switch to achieve optimum load
sharing may be impaired.
Configuring the In-order Delivery Option
In a stable fabric, frames are always delivered in order, even when the traffic between switches is
shared among multiple paths. However, when topology changes occur in the fabric (for instance, a
link goes down), traffic is rerouted around the failure. When topology chan ges occur, some frames
may be delivered out of order.
The default behavior enables out-of-order delivery of frames during fabric topology changes. This
enables fast rerouting after a fabric topology change.

Configuring Compatibility with the F16 Switch
In order for HP Brocade 2400 and 2800 switches to be part of a fabric containing an F16 switch
switch, the VC Encoded Address Mode parameter must be enabled. The VC Encoded Address
Mode parameter specifically enables compatibility between newer switches and the F16 switches.
The VC Encoded Address Mode parameter must be enabled on each HP Brocade 2400 and 2800
switch in the fabric. Enable this parameter only if an F16 switch is in the Fabric.
To enable the VC Encoded Address Mode:
1. Login to the switch as the admin user.
2. At the command line enter the following commands:
switchDisable
configure
3. At the following prompt line enter Yes:
Fabric parameters (yes, y, no, n): [no] yes
4. Press the Enter key to skip through the Fabric Parameters until the VC Encoded Address
Mode parameter is displayed. Enter 1 to enable the parameter:
VC Encoded Address Mode: (0..1) [0] 1
5. Press the Enter key to skip through the rest of the parameters or press Cont rol- D. Verify that
your changes were committed:
Committing configuration...done.
6. Reboot the switch by entering the following command:
fastboot
Note: Once a modification is made to the VC Encoded Address Mode parameter, either fastboot
or cfgEnable is needed to re-install the zoning data base, even if there is already an enabled
or effective Zoning data base.

Reading Hexadecimal Port Diagrams
Many of the commands return port diagrams in Hexadecimal format. For example:
switch:admin> bcastShow
Group Member Ports Member ISL Ports Static ISL Ports
-----------------------------------------------------------256 0x00012083 0x00002080 0x00000000
To read the hexadecimal port diagrams they must be converted into binary notation. Each
hexadecimal value represents four binary val ues. Each hexad ecimal va lue is converted i nto a g roup
four binary values that represent four ports as foll ows:
Hex value = Binary value
0 = 0000
1 = 0001
2 = 0010
3 = 0011
4 = 0100
5 = 0101
6 = 0110
7 = 0111
8 = 1000
9 = 1001
A = 1010
B = 1011
C = 1100
D = 1101
E = 1110
F = 1111
Once the hexadecimal is converted into a binary bit map, each bit represents a port, where a value
of 1 means yes and a value of 0 means no. The bit map is read from right to left, that is, the least
significant bit represents port 0.
For example, if the member port value is displayed in hex as:
0x00012083
This corresponds to a binary bit map of the member ports as follows:
0000 0000 0000 0001 0010 0000 1000 0011
This bit map displays the member ports as port 0, 1, 7, 13, and 16. Each switch has a hidden
internal port (in the example above port 16) which is always a member of a broadcast group.

Working with the Management Server
This chapter provides information on working with the Management Server platform database.
The Management Server allows a Storage Area Network (SAN) management application to
retrieve and administer the fabric and interconnect elements such as switches, servers, and storage
devices. it is located at the Fibre Channel well-known address, FFFFFAh.
Note: Management Server Platform service is available only with Fabric OS V2.3 and later . I f the
Management Server Platform service is started on a fabric with any switches of 2.2.x or
earlier, the fabric will be segmented.
Configuring Access to the Managemen t Server
An Access Control List (ACL) of WWN addresses determines which systems have access to the
Management Server database. If the list is empty (default), the Man agemen t Ser ver is accessible to
all systems connected in-band to the Fabric. For a more secured access, an administrator may
specify WWNs in the ACL. These WWNs are usually associated with the management
applications. If any WWNs are entered into the ACL then access to the Management Server is
restricted to only those WWNs listed in the ACL.
