portMirror 2 portMirror Adds, deletes, or displays port mirror connections. SYNOPSIS portmirror portmirror --show portmirror --add [slot/]port SID DID portmirror --delete SID DID DESCRIPTION Use this command to add, delete, or display a mirror connection between two ports, a source and a destination port. When used without operand, this command displays the usage. Port mirroring allows you to configure any switch port in such a way that it will mirror the traffic passing in both directions between a specified source port (SID) and a destination port (DID) back to the configured mirror port. You can use this feature to troubleshoot Fiber Channel end-to-end link communications. The port mirroring feature mirrors only those frames to the mirror port that contain the specified SID/DID. It does not mirror all frames transmitted or received for a given port. This restriction allows a single mirror port to mirror multiple mirror connections. The SID must be located in the same domain where the mirror port is configured. The following configurations are supported. • SID, DID and mirror port reside in the same blade. • SID, DID and mirror port reside in the same switch (standalone platform). • SID, DID and mirror port reside in different blades in the same chassis. • SID, DID and mirror port reside in two different chassis or standalone switches connected through interchassis or interswitch links. The DID can be either on the local switch or on a different switch. Any given SID can participate in either one or a maximum of three mirror connections, depending on the switch configuration and switch model associated with the SID. Port mirroring makes use of ASIC resources, and the behavior of this command is therefore dependent on the hardware platform on which the feature is configured. Refer to the Fabric OS Troubleshooting and Diagnostics Guide for information on the following topics: • Platforms that support the port mirroring feature • Supported mirror connection maximums for each platform • Platform-specific feature restrictions • Special configuration considerations and configuration scenarios A mirror connection may be rejected because of an invalid configuration, an unavailability of resources, duplicate entries, a mirror port that is not configured, or an offline connection port. When issued with the --show option, this command displays the following information: Mirror_Port The port number of the mirror port that mirrors the traffic between a SID and a DID. SID Source Port ID. DID Destination Port ID. Fabric OS Command Reference 779 53-1002746-01
