Purpose
See the following example of the command configured at
an interface:
switch(config)# interface ethernet 7/5
switch(config-if)# priority-flow-control
watch-dog-interval on
You can use this same command in interface
Note
configuration mode to enable or disable the PFC
watchdog interval for a specific interface.
See the following example of the command configured at
an interface with a specific shutdown multiplier value
(Cisco NX-OS Release 7.0(3)I7(4) and later releases):
switch(config)# int e1/36
switch(config-if)# priority-flow-control
watch-dog-interval on interface-multiplier 10
Range of values for interface-multiplier is 1 -
Note
10.
Specifies the watchdog interval value. The range is from
100 to 1000 milliseconds.
Specifies when to declare the PFC queue as stuck. The
range is from 1 to 10, and the default value is 1.
Note When the PFC queue is declared as stuck, a
syslog entry is created to record the conditions
of the PFC queue. (Cisco NX-OS Release
7.0(3)I7(4) and later releases)
Configures a PFC watchdog poll-interval multiplier for
™
HiGig interfaces. The range is from 0 to 10, and the
default value is 2. A value of 0 disables this feature on
™
HiGig interfaces.
Displays the PFCWD statistics.
Beginning with Cisco NX-OS Release 7.0(3)I6(1), Cisco
Nexus 9200, 9300, 9300-EX, and 9500 platform switches,
using the detail option, you can account for Ingress drops.
