Usage guidelines
This command takes effect only on cascade ports.
If PEX local forwarding is disabled, the PEX sends any incoming traffic to the parent fabric. The
parent fabric makes forwarding decisions and sends the traffic to the outgoing interfaces.
If PEX local forwarding is enabled, the PEX performs local forwarding for Layer 2 unicast packets
with known MAC addresses and reports other packets to the parent fabric for processing.
When you enable or disable PEX local forwarding on a cascade port, the PEX will go offline and then
come online again.

Usage guidelines
This command takes effect only on cascade ports.
For this command to take effect on a PEX, you must enable PEX local forwarding for that PEX.
If PEX persistent forwarding is enabled, the system will not clear the running data or shut down the
network interfaces on the PEX after the PEX goes offline. The PEX can still perform local forwarding.
If PEX persistent forwarding is disabled, the system clears the running data and shuts down all
network interfaces on the PEX after the PEX goes offline. However, the system does not shut down
