Syntax Parameters pause [buffer-size kilobytes pause-threshold kilobytes resume-threshold kilobytes] • 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 buffer threshold limit (in kilobytes) to send pause frames to a transmitting device to temporarily halt the data transmission, from 0 to 7787. • resume-threshold kilobytes - Enter the threshold limit (in kilobytes) at which a request is sent to the transmitting device 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. Table 126.
