PFC commands
pause
Configures the ingress buffer and pause frame settings 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 (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 traffic (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 reserved for PFC traffic classes is 0 on all
interface types.
