Syntax pfc-shared-buffer-size buffer-size Parameters buffer-size - Enter the size of the priority flow-control buffer in KB, from 0 to 8911. Default 832 KB Command Mode SYSTEM-QOS Usage Information The no version of this command returns the value to the default. Example OS10(conf-sys-qos)# pfc-shared-buffer-size 2000 Supported Releases 10.3.0E or later pfc-shared-headroom-buffer-size Configures the shared headroom size for absorbing the packets after pause frames generate. NOTE: This command is available only on the following platforms: • S5212F-ON, S5224F-ON, S5232F-ON, S5248F-ON, S5296F-ON • Z9100-ON • Z9264F-ON Syntax pfc-shared-headroom-buffer-size headroom-buffer-size Parameters headroom-buffer-size - Enter the size of the priority flow-control headroom buffer in KB, from 1 to 3399. Default 1024 KB Command Mode SYSTEM-QOS Usage Information All PFC-enabled priority groups can use the shared headroom space. Headroom is the buffer space that absorbs the incoming packets after the PFC frames reach the sender. After the threshold is reached, PFC frames generate towards the sender. The packets sent by the sender after the PFC frames generate are absorbed into the Headroom buffer. The no version of this command returns the value to the default.
