2 portMirror portMirror Add/delete/show mirror connection(s). Synopsis portMirror [--show ] [--add [slotnumber/]portnumber sourceID DestID] [--delete [sourceID DestID]] Description Use this command to add/delete/show a mirror connection. The --add option will add a mirror connection between the source and destination. The slotnumber/ portnumber is the mirrored traffic output port. The --delete option will delete a mirror connection between the source and destination. The --show option will output all the configured mirror connections. The SourceID must be local to the switch. The DestID can be either on the local switch or on a different switch. A SourceID can only participate in four mirror connections. The DestID is limited by any existing mirror connections. If the DestID for an existing connection is to a local switch DestID, then all unused connections for this switch must go to a local switch destination IDs. If the DestID for an existing connection is to a domain X switch, then all unused mirror connections for this switch must also go to the same domain X switch. Each internal or external port can only be a member of four mirror connections. Internal ports are used when the DestID is on another blade or another switch (i.e. another blade has an E_Port leading to another switch). A port mirroring connection on FL_Ports mirrors all traffic originating or terminating from this FL_Port. Port mirroring does not support ALPA granularity port mirroring. A mirror connection can be rejected due to an invalid configuration, no resources, duplicate entries, mirror port not configured, or an offline connection port. When in-order deliver (IOD) is enabled, deleting a mirror connection can cause frame loss between the SourceID and DestID. If IOD is disabled, deleting a mirror connection will introduce an "order of delivery" error between the SourceID and DestID. The --show option will display all the configured port mirror connections created by the --add command. This command displays: SID Source Port ID. DID Destination Port ID. Mirror_Port_Number Specifies the port number of the mirror port to mirror the traffic between SourceID and DestID. State The state of the mirror connection 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 due to at least one port not being online. A connection that is "Enabled" has been configured in the hardware. A new connection cannot conflict with a "Defined" or "Enabled" port mirror connection. To display all configured mirror ports on a switch use the portCfgShow command. 514 Fabric OS Command Reference Manual 53-1000436-01
