Rev 1.6.9 • Transmits PFC-PAUSE frames when the receive threshold for a particular traffic class is reached • Provides the management capability for an administrator to configure the flow control properties on each port of the switch • Keeps flow control disabled for all priorities on all ports by default • Allows an administrator to enable or disable flow control per port and per priority level • Supports flow control only on physical ports, not on logical interfaces such as tunnels or interfaces defined by sharing a physical port in multiple virtual switch contexts • Uses the configured threshold values to set up the queue buffer spaces accordingly in the datapath • Provides hardware abstraction layer callouts for the following: • Enabling or disabling of flow control on each port for each priority • Configuring the queue depth for each priority on each port • Supports MIB defined in the 802.1Qbb standard and a proprietary MIB for management • Provides trace logs for execution upon error conditions and for any event notifications from the hardware or datapath. These trace logs are a useful aid in troubleshooting. • Allows the administrator to configure the minimum and maximum threshold values for flow control. These configurations are applied globally on all ports and priorities. Priority Based Flow Control (PFC) provides an enhancement to the existing pause flow control mechanism as described in 802.1X.  To enable PFC globally: Step 1. Log in as admin. Step 2. Enter config mode. Run: switch > enable switch # configure terminal Step 3. Enable PFC globally on the switch. Run: switch (config) # dcb priority-flow-control enable This action might cause traffic loss while shutting down a port with priority-flow-control mode on Type 'yes' to confirm enable pfc globally: yes  To enable PFC per priority: Step 1. Log in as admin. Step 2. Enter config mode. Run: switch > enable switch # configure terminal Step 3. Enable PFC globally on the switch.

•

Transmits PFC-PAUSE frames when the receive threshold for a particular traffic class is

reached

•

Provides the management capability for an administrator to configure the flow control

properties on each port of the switch

•

Keeps flow control disabled for all priorities on all ports by default

•

Allows an administrator to enable or disable flow control per port and per priority level

•

Supports flow control only on physical ports, not on logical interfaces such as tunnels or

interfaces defined by sharing a physical port in multiple virtual switch contexts

•

Uses the configured threshold values to set up the queue buffer spaces accordingly in

the datapath

•

Provides hardware abstraction layer callouts for the following:

•

Enabling or disabling of flow control on each port for each priority

•

Configuring the queue depth for each priority on each port

•

Supports MIB defined in the 802.1Qbb standard and a proprietary MIB for management

•

Provides trace logs for execution upon error conditions and for any event notifications

from the hardware or datapath. These trace logs are a useful aid in troubleshooting.

•

Allows the administrator to configure the minimum and maximum threshold values for

flow control. These configurations are applied globally on all ports and priorities.

Priority Based Flow Control (PFC) provides an enhancement to the existing pause flow control

mechanism as described in 802.1X.

To enable PFC per priority:

Step 1.

Step 2.

Enter config mode. Run:

Step 3.

Enable PFC globally on the switch. Run:

switch > enable

switch # configure terminal

switch (config) # dcb priority-flow-control enable

This action might cause traffic loss while shutting down a port with priority-flow-con-

trol mode on

Type 'yes' to confirm

enable pfc globally: yes
