Netgear M4300-24X24F (XSM4348S) - Stackable Managed Switch with 48x10G including 24x10GBASE-T and 24xSFP+ Layer 3 Guia Do Programa

This section describes the commands you use to configure provisioning (IEEE 802.1p,) 
which allows you to prioritize ports.

This command configures the port priority assigned for untagged packets for all ports 
presently plugged into the device. The range for the priority is 0-7. Any subsequent per port 
configuration will override this configuration setting.

This command configures the default 802.1p port priority assigned for untagged packets for a 
specific interface. The range for the priority is 0–7.

When in asymmetric flow control mode, the switch responds to PAUSE frames received from 
a peer by stopping packet transmission, but the switch does not initiate MAC control PAUSE 
frames.

When you configure the switch in asymmetric flow control (or no flow control mode), the 
device is placed in egress drop mode. Egress drop mode maximizes the throughput of the 
system at the expense of packet loss in a heavily congested system, and this mode avoids 
head-of-line blocking.

Use this command to enable the symmetric or asymmetric flow control on the switch. 

Asymmetric flow control means you can enable Rx Pause only but not Tx Pause.
