Bypassing the Queuing Chip
When flexible queuing option is enabled, QoS is applied on all the configured ports. Applying QoS on the ports requires additional vCPU reserve for each port and this affects vCPU resource allocation. By default, all traffic passes through the queuing-chip, which decreases the available vCPU resource, there by affecting the performance.
Starting with Junos OS 18.2R1, you can bypass the queuing-chip on vMX routers to save vCPU resources when scheduling is not needed on an interface. In cases when you do not require QoS features such as hierarchical scheduling or per-vlan queuing on a particular interface, you can bypass the queuing-chip to increase the available bandwidth.
Use the following commands to enable bypass queue option:
Enable bypass the queuing-chip on vMX VM:
content_copy zoom_out_map[edit interfaces]user@router# set ge-0/0/1 bypass-queuing-chipNote:Enabling the bypass queue option reboots the FPC.
When you configure the bypass queuing chip option, the
show interface queuecommand does not display any output.Optionally you can configure to share the resources (QoS scheduling and Workers) among a selected set of ports. This feature is supported for active-standby configuration of LAG.
content_copy zoom_out_map[edit interfaces]user@router# set interfaces ae0 aggregated-ether-options share-standbyWhen you configure the share-standby option, all the members of aggregated Ethernet (AE) interface share the same resources (vCPUs) for both Worker processing and QoS scheduling.
