IP Phone Interoperation Solution

IP Phone Interoperation Solution

NOTE:

Huawei PoE switches can supply power to IP phones. For details, see Power Supply Guide for Interoperation Between Huawei PoE Switches and IP Phones.

Different solutions are available for connecting IP phones with different attributes to different device models. For details, see List of IP Phone Models That Can Be Connected to Switches. The following table provides detailed configuration guidance for the interoperation solutions. You can select a solution based on the device model, version, and applicable scenario.

Interoperation Solution

Applicable Scenario

Applicable S Series Switch and Version

(Recommended) Interoperation Between Switches and IP Phones Through LLDP

  • IP phones can obtain voice VLAN IDs through LLDP.

  • Switches that are enabled with the voice VLAN function can identify voice packets based on voice VLAN IDs and increase the packet priority.
  • MAC address authentication is configured for IP phones, and 802.1X authentication is configured for the PC.

All versions and all models except the S2700SI and S2710SI.

(Recommended) Interoperation Between Switches and IP Phones Through the OUI-based Voice VLAN

  • IP phones cannot obtain voice VLAN IDs through any protocol, and voice packets are forwarded in the VLAN specified through the voice VLAN function.
  • Switches that are enabled with the voice VLAN function can identify voice packets based on MAC addresses and increase the packet priority.
  • MAC address authentication is configured for IP phones.

All models of V200R003C00 and later versions.

(Recommended) Interoperation Between Switches and Cisco IP Phones Using HDP

  • IP phones can obtain voice VLAN IDs through CDP.
  • Switches that are enabled with the voice VLAN function can identify voice packets based on voice VLAN IDs and increase the packet priority.
  • 802.1X authentication is configured for IP phones.
All versions and all models.

Interoperation Between Switches and IP Phones Through LLDP-MED

  • IP phones can obtain voice VLAN IDs based on the network-policy TLV field of LLDP.
  • The packet priority is high, and switches do not need to increase the packet priority.
  • 802.1X authentication and MAC address authentication are configured for IP phones.

All models of V200R002 and later versions.

Interoperation Between Switches and IP Phones Through MAC Address-based VLAN Assignment

  • IP phones cannot obtain voice VLAN IDs through any protocol, and voice packets are forwarded in the VLAN specified through MAC address-based VLAN assignment.
  • Switches that are enabled with the MAC address-based assignment function can identify voice packets based on MAC addresses and increase the packet priority.
  • IP phones can go online directly without authentication.
All versions and all models.

Interoperation Between Switches and IP Phones Through the PVID of the Voice VLAN ID

  • IP phones cannot obtain voice VLAN IDs through any protocol, and voice packets are forwarded in the VLAN specified through the PVID of the interface.
  • Switches that are enabled with the voice VLAN function can identify voice packets based on MAC addresses and increase the packet priority.
  • MAC address authentication is configured for IP phones.
All versions and all models.

Interoperation Between Switches and IP Phones Through an ACL

  • IP phones cannot obtain voice VLAN IDs through any protocol, and voice packets are forwarded in the VLAN specified through an ACL.
  • Switches that are configured with ACLs can identify voice packets based on MAC addresses and increase the packet priority.
  • 802.1X authentication is configured for IP phones.
All modular switches and the following fixed switches:
  • S2700 series: S2752EI
  • S3700 series: all models
  • S5700 series: S5700EI, S5700HI, S5710EI, S5720EI, S5710HI, S5720HI, and S5730HI
  • S6700 series: S6700EI, S6720EI, S6720S-EI, and S6720HI

Interoperation Between Switches and IP Phones Through a Simplified Traffic Policy

  • IP phones cannot obtain voice VLAN IDs through any protocol, and voice packets are forwarded in the VLAN specified through a traffic policy.
  • Switches that are configured with traffic policies can identify voice packets based on MAC addresses and increase the packet priority.
  • 802.1X authentication is configured for IP phones.

All versions and models of fixed switches.

All modular switches of V200R005C00 and later versions.
