Parameter | Description |
gigabit-ethernet <interface-name> | Specifies the name of a physical interface in the ingress direction of the downstream switch. |
ingress-queue <queue-id> | Specifies the queue number of an ingress interface. The value is an integer that ranges from 0 to 7. Note: On Trident and Trident+ based switches, known unicast packets can be assigned to a specific queue between queues from 0 to 7, while unknown unicast packets, multicast packets, and broadcast packets can be assigned to a specific queue between queues from 0 to 3. |
headroom <value> | Specifies the upper threshold of headroom buffer for a PFC queue on the ingress interface. When the headroom buffer threshold is reached, the received packets will be dropped. The value is an integer that ranges from 1 to 65535. Unit: cell. Note: The values of cell are different on different platforms. The value is 256 bytes on Trident3-X5 and Trident3-X7 platforms, and is 254 bytes on the Tomahawk3 platform. |
Example
Set the upper threshold of headroom buffer for PFC queue 3 on the ingress interface xe-1/1/3 as 2400 cells.
