A stack has a limitof one port mirroring session and one destination port. Remove an existing source or destination portbefore replacing it with another. For more on configuring port monitoring (port mirroring), see the PortMirroring chapter of the SFTOS Configuration Guide.monitor session 1 modeThis command sets the monitor session (port monitoring) mode to enabled. The probe and monitoredports must be configured before port monitoring can be enabled. When enabled, the probe portmonitors all traffic received and transmitted on the physical monitored port. It is not necessary todisable port monitoring before modifying the probe and monitored ports.A session is operationally active if and only if both a destination port and at least one source port isconfigured. If neither is true, the session is inactive.A port configured as a destination port acts as a mirroring port when the session is operationally active.If it is not, the port acts as a normal port and participates in all normal operation with respect totransmitting traffic.Syntax [no] monitor session 1 modeThe no version of this command sets the monitor session (port monitoring) mode to disabled.Default disabledMode Global ConfigParameters destination interfaceunit/slot/portSpecify the probe port (target port).
