PFC commands
pause
Congures the ingress buer and pause frame settings used for PFC trac classes.
Syntax
pause [buffer-size kilobytes pause-threshold kilobytes resume-threshold
kilobytes]
Parameters
• buffer-size kilobytes — Enter the reserved (guaranteed) ingress-buer size in kilobytes for PFC
dot1p trac (0 to 7787).
• pause-threshold kilobytes — Enter the threshold used to send pause frames in kilobytes to a
transmitting device (0 to 7787).
•
resume-threshold kilobytes — Enter the threshold used to request a transmitting device in kilobytes
to resume sending trac (0 to 7787).
Defaults
The default ingress-buer size reserved for PFC trac classes, and the pause and resume thresholds vary
according to the interface type. The default egress buer reserved for PFC trac classes is 0 on all interface
types.
