SD Port Characteristics

An SD port has the following characteristics:

• Ignores BB_credits.
• Allows data traffic only in the egress (Tx) direction.
• Does not require a device or an analyzer to be physically connected.
• Supports only 1 Gbps or 2 Gbps speeds. The auto speed option is not allowed.
• Multiple sessions can share the same destination ports.
• If the SD port is shut down, all shared sessions stop generating SPAN traffic.
• The outgoing frames can be encapsulated in Extended Inter-Switch Link (EISL) format.
• 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.

Note     If you need to change an SD port mode to another port mode, first remove the SD port from all sessions and then change the port mode.
