Feature Limitations

  • The switch XGE interface connected to ET1D2IPS0S00, ET1D2FW00S00, ET1D2FW00S01, ET1D2FW00S02, or ACU2 does not support voice VLAN.

  • VLAN 1 cannot be configured as a voice VLAN.

  • To transmit different services, ensure that the voice VLAN and default VLAN on an interface are different VLANs.

  • Only one VLAN on an interface can be configured as a voice VLAN at a time.

  • After a voice VLAN is configured on an interface, VLAN mapping, VLAN stacking, or traffic policies cannot be configured on the interface.

  • Do not set the VLAN ID to 0 on an IP phone.
  • X series cards on modular switches does not support the automatic mode.
  • In auto mode, access, negotiation-auto, or negotiation-desirable interfaces cannot be added to a voice VLAN. To add the interface to the voice VLAN, run the port link-type command to change the link type of the interface to trunk or hybrid.
  • When an IP phone is connected to a switch through the OUI-based voice VLAN, disable LLDP on the interface. If LLDP is enabled on the interface, the switch will allocate a voice VLAN ID to the IP phone. The IP phone sends tagged packets to the switch, whereas the switch sends untagged packets to the IP phone. As a result, the IP phone cannot go online.
  • In V200R003 and later versions, the automatic mode takes effect only when the voice-vlan remark-mode mac-address command is configured to increase the priority of voice packets based on MAC addresses and the voice-vlan enable command without include-untagged specified is configured to enable voice VLAN on the interface.
  • When the outbound interface is located on the ES0D0G24SA00 or ES0D0G24CA00 of the S7700, or EH1D2G24SSA0 or EH1D2S24CSA0 of the S9700, the 802.1p priority cannot be changed.
  • When the remark (user group view) and voice-vlan remark commands are used together to modify the user packet priority, if the services conflict:

    • For X series cards, the priority configured using the remark (user group view) command takes effect.
    • For the non-X series cards, the priority configured using the voice-vlan remark command takes effect.
