The SD port does not have a port VSAN.
SD ports cannot be configured using Storage Services Modules (SSMs).
The port mode cannot be changed if it is being used for a SPAN session.
You can configure up to 16 SPAN sessions with multiple ingress (Rx) sources.
You can configure a maximum of three SPAN sessions with one egress (Tx) port.
In a 32-port switching module, you must configure the same session in all four ports in one port
