283 | .I VLAN | |
284 | the following additional arguments are supported: | |

286 | .BI "ip link add | |

314 | .sp | |
315 | .BI protocol " VLAN_PROTO " | |
316 | - either 802.1Q or 802.1ad. | |
317 | ||
318 | .BI id " VLANID " | |
319 | - specifies the VLAN Identifer to use. Note that numbers with a leading " 0 " or " 0x " are interpreted as octal or hexadeimal, respectively. | |
320 | ||
321 | .BR reorder_hdr " { " on " | " off " } " | |
322 | - specifies whether ethernet headers are reordered or not (default is | |
323 | .BR on ")." | |
324 | ||
325 | .in +4 | |
326 | If | |
327 | .BR reorder_hdr " is " on | |
328 | then VLAN header will be not inserted immediately but only before passing to the | |
329 | physical device (if this device does not support VLAN offloading), the similar | |
330 | on the RX direction - by default the packet will be untagged before being | |
331 | received by VLAN device. Reordering allows to accelerate tagging on egress and | |
332 | to hide VLAN header on ingress so the packet looks like regular Ethernet packet, | |
333 | at the same time it might be confusing for packet capture as the VLAN header | |
334 | does not exist within the packet. | |
335 | ||
336 | VLAN offloading can be checked by | |
337 | .BR ethtool "(8):" | |
338 | .in +4 | |
339 | .sp | |

343 | .sp | |

347 | ||
348 | .BR gvrp " { " on " | " off " } " | |
349 | - specifies whether this VLAN should be registered using GARP VLAN Registration Protocol. | |
350 | ||
351 | .BR mvrp " { " on " | " off " } " | |
352 | - specifies whether this VLAN should be registered using Multiple VLAN Registration Protocol. | |
353 | ||
354 | .BR loose_binding " { " on " | " off " } " | |
355 | - specifies whether the VLAN device state is bound to the physical device state. | |
356 | ||
357 | .BI ingress-qos-map " QOS-MAP " | |
358 | - defines a mapping of VLAN header prio field to the Linux internal packet | |
359 | priority on incoming frames. The format is FROM:TO with multiple mappings | |
360 | separated by spaces. | |
361 | ||
362 | .BI egress-qos-map " QOS-MAP " | |
363 | - defines a mapping of Linux internal packet priority to VLAN header prio field | |
364 | but for outgoing frames. The format is the same as for ingress-qos-map. | |
365 | .in +4 | |
366 | ||
367 | Linux packet priority can be set by | |
368 | .BR iptables "(8)": | |
369 | .in +4 | |

372 | -t mangle -A POSTROUTING [...] -j CLASSIFY --set-class 0:4 | |
373 | .sp | |

1098 | .BR "@SYSCONFDIR@/group" . | |
1099 | ||
1100 | .TP | |
1101 | .BI vf " NUM" | |
1102 | specify a Virtual Function device to be configured. The associated PF device | |
1103 | must be specified using the | |
1104 | .B dev | |
1105 | parameter. | |
1106 | ||
1107 | .in +8 | |
1108 | .BI mac " LLADDRESS" | |
1109 | - change the station address for the specified VF. The | |
1110 | .B vf | |
1111 | parameter must be specified. | |
1112 | ||
1113 | .sp | |
1114 | .BI vlan " VLANID" | |
1115 | - change the assigned VLAN for the specified VF. When specified, all traffic | |
1116 | sent from the VF will be tagged with the specified VLAN ID. Incoming traffic | |
1117 | will be filtered for the specified VLAN ID, and will have all VLAN tags | |
1118 | stripped before being passed to the VF. Setting this parameter to 0 disables | |
1119 | VLAN tagging and filtering. The | |
1120 | .B vf | |
1121 | parameter must be specified. | |
1122 | ||
1123 | .sp | |
1124 | .BI qos " VLAN-QOS" | |
1125 | - assign VLAN QOS (priority) bits for the VLAN tag. When specified, all VLAN | |
1126 | tags transmitted by the VF will include the specified priority bits in the | |
1127 | VLAN tag. If not specified, the value is assumed to be 0. Both the | |
1128 | .B vf | |
1129 | and | |
1130 | .B vlan | |
1131 | parameters must be specified. Setting both | |
1132 | .B vlan | |
1133 | and | |
1134 | .B qos | |
1135 | as 0 disables VLAN tagging and filtering for the VF. | |
1136 | ||
1137 | .sp | |
1138 | .BI rate " TXRATE" | |
1139 | -- change the allowed transmit bandwidth, in Mbps, for the specified VF. | |
1140 | Setting this parameter to 0 disables rate limiting. | |
1141 | .B vf | |
1142 | parameter must be specified. | |
1143 | Please use new API | |
1144 | .B "max_tx_rate" | |
1145 | option instead. | |
1146 | ||
1147 | .sp | |
1148 | .BI max_tx_rate " TXRATE" | |
1149 | - change the allowed maximum transmit bandwidth, in Mbps, for the specified VF. | |
1150 | .B vf | |
1151 | parameter must be specified. | |
1152 | ||
1153 | .sp | |
1154 | .BI min_tx_rate " TXRATE" | |
1155 | - change the allowed minimum transmit bandwidth, in Mbps, for the specified VF. | |
1156 | Minimum TXRATE should be always <= Maximum TXRATE. | |
1157 | .B vf | |
1158 | parameter must be specified. | |
1159 | ||
1160 | .sp | |
1161 | .BI spoofchk " on|off" | |
1162 | - turn packet spoof checking on or off for the specified VF. | |
1163 | .sp | |
1164 | .BI query_rss " on|off" | |
1165 | - toggle the ability of querying the RSS configuration of a specific VF. VF RSS information like RSS hash key may be considered sensitive on some devices where this information is shared between VF and PF and thus its querying may be prohibited by default. | |
1166 | .sp | |
1167 | .BI state " auto|enable|disable" | |
1168 | - set the virtual link state as seen by the specified VF. Setting to auto means a | |
1169 | reflection of the PF link state, enable lets the VF to communicate with other VFs on | |
1170 | this host even if the PF link state is down, disable causes the HW to drop any packets | |
1171 | sent by the VF. | |
1172 | .sp | |
1173 | .BI trust " on|off" | |
1174 | - trust the specified VF user. This enables that VF user can set a specific feature | |
1175 | which may impact security and/or performance. (e.g. VF multicast promiscuous mode) | |
1176 | .in -8 | |
1177 | ||
1178 | .TP | |
1179 | .BI master " DEVICE" | |
1180 | set master device of the device (enslave device). | |
1181 | ||
1182 | .TP | |
1183 | .BI nomaster | |
1184 | unset master device of the device (release device). | |
1185 | ||
1186 | .TP | |
1187 | .BI addrgenmode " eui64|none|stable_secret|random" | |
1188 | set the IPv6 address generation mode | |
1189 | ||
1190 | .I eui64 | |
1191 | - use a Modified EUI-64 format interface identifier | |
1192 | ||
1193 | .I none | |
1194 | - disable automatic address generation | |
1195 | ||
1196 | .I stable_secret | |
1197 | - generate the interface identifier based on a preset /proc/sys/net/ipv6/conf/{default,DEVICE}/stable_secret | |
1198 | ||
1199 | .I random | |
1200 | - like stable_secret, but auto-generate a new random secret if none is set | |
1201 | ||
1202 | .TP | |
1203 | .BR "link-netnsid " | |
1204 | set peer netnsid for a cross-netns interface | |
1205 | ||

1207 | .B Warning: | |
1208 | If multiple parameter changes are requested, | |
1209 | .B ip | |
1210 | aborts immediately after any of the changes have failed. | |
1211 | This is the only case when | |
1212 | .B ip | |
1213 | can move the system to an unpredictable state. The solution | |
1214 | is to avoid changing several parameters with one | |

1245 | Note that the type name is not checked against the list of supported types - | |
1246 | instead it is sent as-is to the kernel. Later it is used to filter the returned | |
1247 | interface list by comparing it with the relevant attribute in case the kernel | |
1248 | didn't filter already. Therefore any string is accepted, but may lead to empty | |
1249 | output. | |
