Dell Brocade 6520 Command Reference Supporting Fabric OS v7.1.0 - Page 808

2 portMirror NOTES OPERANDS State 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. 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. 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. This command has the following operands: --show Displays all configured mirror connections. --add 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. 780 Fabric OS Command Reference 53-1002746-01
