PFC commands
pause
Configures the ingress buffer and pause frame settings that are used for PFC traffic classes.
Syntax
pause [buffer-size kilobytes pause-threshold kilobytes resume-threshold
kilobytes]
Parameters
• buffer-size kilobytes — Enter the reserved (guaranteed) ingress-buffer size in kilobytes for PFC
dot1p traffic, from 0 to 7787.
• pause-threshold kilobytes — Enter the threshold used to send pause frames in kilobytes to a
transmitting device, from 0 to 7787.
• resume-threshold kilobytes — Enter the threshold used to request a transmitting device in kilobytes
to resume sending traffic, from 0 to 7787.
Defaults
The default ingress-buffer size reserved for PFC traffic classes, and the pause and resume thresholds, vary
according to the interface type. The default egress buffer that is reserved for PFC traffic classes is 0 on all
interface types.
