10 FTRACE concepts The configuration database keeps information about the number of port mirror connections configured on a switch, the number of chunks of port mirroring data that are stored, and the chunk number. When removing a mirror connection, always use this method to ensure that the data is cleared. Deleting a connection removes the information from the database. Deleting a port mirror connection 1. Connect to the switch and log in using an account assigned to the admin role. 2. Enter the portMirror --del SourceID DestID command. For example, to delete the port mirror connection on mirror port 2, you might type: switch:admin> portMirror --del 0x011400 0x240400 Displaying port mirror connections 1. Connect to the switch and log in using an account assigned to the admin role. 2. Enter the portMirror --show command. You should see output similar to the following: switch:admin> portmirror --show Number of mirror connection(s) configured: 4 Mirror_Port SID DID State 18 0x070400 0x0718e2 Enabled 18 0x070400 0x0718e3 Enabled 18 0x070400 0x0718ef Enabled 18 0x070400 0x0718e0 Enabled FTRACE concepts FTRACE is a support tool that can be used in a manner similar to that of a channel protocol analyzer.

FTRACE record events that occur on the FC interface, including user defined messages and events. FTRACE includes the ability to freeze traces on certain events, and to retain the trace information for future examination.

The configuration database keeps information about the number of port mirror connections
configured on a switch, the number of chunks of port mirroring data that are stored, and the chunk
number. When removing a mirror connection, always use this method to ensure that the data is
cleared. Deleting a connection removes the information from the database.
Deleting a port mirror connection
1.
Connect to the switch and log in using an account assigned to the admin role.
2.
Enter the
portMirror
--
del
SourceID DestID
command.
For example, to delete the port mirror connection on mirror port 2, you might type:
switch:admin>
portMirror --del 0x011400 0x240400
Displaying port mirror connections
1.
Connect to the switch and log in using an account assigned to the admin role.
2.
Enter the
portMirror
--
show
command.
You should see output similar to the following:
switch:admin>
portmirror --show
Number of mirror connection(s) configured: 4

Fibre Channel trace information
Frame trace (FTRACE) records user-defined messages and events on the Brocade FR4-18i and the

option to capture trace information on a per FCIP
tunnel basis. You can configure up to eight FCIP tunnels on a single physical GE port. FTRACE is
subject to the same FCIP tunnel limitations, such as tunnel disruption, port of switch disable or
enable, and reboot requirements.
