Description
Enabling tracing can adversely impact scale and performance and may increase security risk. We strongly recommend using the trace, tracing, or traceoptions commands only under the guidance of a JTAC support engineer. After collecting the debug information, immediately disable tracing to minimize risk and restore normal system performance.
Establish multicast snooping option values.
Options
| conserve-mcast-routes-in-pfe |
Don't install snooping routes in forwarding plane. We introduced this option specifically for single lookup platforms operating as centrally routed bridging (CRB) spines. This option should not be configured on QFX5110/QFX5120 when deployed in Server Leaf role. It should only be configured in QFX5120 devices operating as CRB Spines. |
| multicast-router-job-pause |
Pause the multicast router handling job. |
| multicast-router-no-flood-job-pause |
Pause the multicast router no-flood handling job. |
| multichassis-lag-replicate-state |
Enable multichassis lag replication.
