ST Port Characteristics

ST port have the following characteristics:

The RSPAN tunnel begins in the source switch and terminates in the destination switch. This section

assumes Switch S to be the source and Switch D to be the destination.

Besides the source and destination switches, the VSAN must also be configured in each Cisco MDS

switch in the Fibre Channel fabric, if they exist.

To monitor network traffic using the RSPAN feature, follow these steps:

Create VSAN interfaces in destination switch (Switch D) and source switch (Switch S) to facilitate the

Fibre Channel tunnel (FC tunnel) creation.

Enable the FC tunnel in each switch in the end-to-end path of the tunnel.

Initiate the FC tunnel (in Switch S) and map the tunnel to the VSAN interface's IP address (in Switch

D) so all RSPAN traffic from the tunnel is directed to the SD port.

Configure SD ports for SPAN monitoring in the destination switch (Switch D).

Configure the ST port in the source switch (Switch S) and bind the ST port to the FC tunnel.

Create an RSPAN session in the source switch (in Switch S) to monitor network traffic.

This section provides a RSPAN configuration example using the procedure defined in the previous

This section identifies the tasks that must be performed in the source switch (Switch D):

Cisco MDS 9000 Family Configuration Guide

ST ports perform the RSPAN encapsulation of the FC frame.

ST ports do not use BB_credits.

One ST port can only be bound to one FC tunnel.

ST ports cannot be used for any purpose other than to carry RSPAN traffic.

ST Ports cannot be configured using Advanced Services Modules (ASMs) or Storage Services

Modules (SSMs).
