portCfg
mirrorport
Configures a mirror port on the local port. The port mirroring feature reroutes data frames
between two devices to the mirror port. Port mirroring can aid in troubleshooting common
FC end-to-end communication problems. The command prompts for confirmation that the
specified port be enabled as a mirror port. Once a port is configured as a mirror port, the
port can only be used as part of a mirror connection. Port Mirroring is not supported over
FCIP links (VE tunnels). The port mirroring feature is not supported on the Gen6 platforms.
The syntax for portCfg mirrorport is as follows:
portcfg mirrorport [slot/]port mode
Valid modes for mirrorport include the following:
--disable
Disables the configuration. When disabled, a port cannot be a mirror port.
--enable

connection can use this port to mirror traffic.
