portMirror
State
You must enable port mirroring on the port before you can configure mirror connections for that port. Use
portcfg mirrorport --enable to enable a port for port mirroring. Use the portCfgShow command to
display all mirror ports on a switch. The switchShow command displays the configured port as "Mirror
Port".
Use the portPerfShow command to display the total number of transmitted and received bytes for each
port. In the case of a mirror port, this command shows twice the amount of traffic, because the mirror port
transmits and receives the frames.
NOTES
The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in
place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for
details.
The port mirroring feature is not supported on all platforms. Refer to the Fabric OS Administrator's Guide
for more information.
The port mirroring feature is supported in Virtual Fabric mode so long as the FC Routing service is not
enabled on the logical switch. Use the fosConfig command to disable the FC Routing service.
The Brocade 300, 5300, and most embedded switches can participate only in one mirror connection. All
other platforms support up to three mirror connections. These limitations hold regardless of whether
Virtual Fabrics are enabled or disabled.
When in-order deliver (IOD) is enabled, deleting a mirror connection can cause frame loss between the
SID and DID. If IOD is disabled, deleting a mirror connection may introduce an "order of delivery" error
between the SID and DID.
Port mirroring is not supported over FCIP links (VE tunnels) or on Condor 3 FC ports that have
encryption or compression enabled.
OPERANDS
This command has the following operands:
--show
--add
754
The state of the mirror connection. The state can either be "Defined" or "Enabled."
In both cases, the port mirroring connection is persistently stored. A connection
that is "Defined" has not been hardware-configured because at least one port is
not online. A connection that is "Enabled" has been configured in the hardware.
Displays all configured mirror connections.
Adds a mirror connection between a source port and a destination port.
slot
For bladed systems only, specifies the slot number of the port to be configured,
followed by a slash (/).
port
Specifies the number of the port to be configured, relative to its slot for bladed
systems. This port is the mirror port, in which the mirror traffic is shown. Use
switchShow for a listing of valid ports.
SID
Specifies the 3-byte source ID of the originator device in "0xDDAAPP" format,
where DD is the Domain ID, AA is the Area ID and PP is the AL_PA ID. For
example, 0x050200 has a domain ID of 5, an area ID of 2, and an AL_PA ID of 0.
The values for the SID and the DID cannot both be 0x000000.
DID
Specifies the 3-byte DID destination ID of the destination device, in "0xDDAAPP"
format, where DD is Domain ID, AA is Area ID and PP is AL_PA ID. For example,
0x050200 has a domain ID of 5, an area ID of 2 and an AL_PA ID of 0. The values
for the SID and the DID cannot both be 0x000000.
