License Support

VLAN is a basic feature of a router and is not under license control.

Feature Dependencies and Limitations

  • You are advised to plan service and management VLANs so that any broadcast storms in service VLANs do not affect device management.
  • In practice, specify VLANs from which packets need to be transparently transmitted by a trunk interface. Do not use the port trunk allow-pass vlan all command if possible.
  • All interfaces join VLAN 1 by default. When unknown unicast, multicast, or broadcast packets of VLAN 1 exist on the network, broadcast storms may occur. When VLAN 1 is used, pay attention to the following points:
    • Remove the interfaces that do not need to join VLAN 1 from VLAN 1 to prevent loops.
    • You are advised to remove interfaces from VLAN 1 in Eth-Trunk or ring networking.
    • When connecting to an access device, to prevent broadcast storms in VLAN 1, do not configure the uplink interface of the access device to transparently transmit packets from VLAN 1.

AR502G-L-D-H and AR502GR-L-D-H do not support VLAN technology.

AR510 series do not support VLAN technology.
