515 | .SH bridge vlan - VLAN filter list |
516 | ||
517 | .B vlan | |
518 | objects contain known VLAN IDs for a link. | |
519 | ||
520 | .P | |
521 | The corresponding commands display vlan filter entries, add new entries, | |
522 | and delete old ones. | |
523 | ||
524 | .SS bridge vlan add - add a new vlan filter entry | |
525 | ||
526 | This command creates a new vlan filter entry. | |
527 | ||
528 | .TP | |

533 | .BI vid " VID" | |
534 | the VLAN ID that identifies the vlan. | |
535 | ||
536 | .TP | |
537 | .BI pvid | |
538 | the vlan specified is to be considered a PVID at ingress. | |
539 | Any untagged frames will be assigned to this VLAN. | |
540 | ||
541 | .TP | |
542 | .BI untagged | |
543 | the vlan specified is to be treated as untagged on egress. | |
544 | ||
545 | .TP | |
546 | .BI self | |
a89d5329 | 547 | the vlan is configured on the specified physical device. Required if the |
ab938710 VY |
548 | device is the bridge device. |
549 | ||
550 | .TP | |
551 | .BI master | |
6274b0b7 | 552 | the vlan is configured on the software bridge (default). |

554 | .SS bridge vlan delete - delete a forwarding database entry | |
555 | This command removes an existing fdb entry. | |
556 | ||
557 | .PP | |
558 | The arguments are the same as with | |
559 | .BR "bridge vlan add". | |
560 | The | |

568 | .SH bridge monitor - state monitoring |
569 | ||
570 | The | |
571 | .B bridge | |
fc31817d | 572 | utility can monitor the state of devices and addresses |
a89d5329 | 573 | continuously. This option has a slightly different format. |
d04bc300 SH |
574 | Namely, the |
575 | .B monitor | |
576 | command is the first in the command line and then the object list follows: | |
577 | ||
578 | .BR "bridge monitor" " [ " all " |" | |
49572501 | 579 | .IR OBJECT-LIST " ]" |
d04bc300 SH |
580 | |
581 | .I OBJECT-LIST | |
582 | is the list of object types that we want to monitor. | |
583 | It may contain | |
fc31817d | 584 | .BR link ", " fdb ", and " mdb "." |
d04bc300 SH |
585 | If no |
586 | .B file | |
587 | argument is given, | |
588 | .B bridge | |
589 | opens RTNETLINK, listens on it and dumps state changes in the format | |
590 | described in previous sections. | |
591 | ||
592 | .P | |
593 | If a file name is given, it does not listen on RTNETLINK, | |
594 | but opens the file containing RTNETLINK messages saved in binary format | |
efb16971 | 595 | and dumps them. |

596 | |
597 | .SH NOTES | |
598 | This command uses facilities added in Linux 3.0. | |
599 | ||
600 | Although the forwarding table is maintained on a per-bridge device basis | |
601 | the bridge device is not part of the syntax. This is a limitation of the | |
602 | underlying netlink neighbour message protocol. When displaying the | |
603 | forwarding table, entries for all bridges are displayed. | |
604 | Add/delete/modify commands determine the underlying bridge device | |
6274b0b7 | 605 | based on the bridge to which the corresponding ethernet device is attached. |
