Configuration Guide - Ethernet Switching

S7700 and S9700 V200R012C00

This document describes the configuration of Ethernet services, including configuring MAC address table, link aggregation, VLANs, VLAN aggregation, MUX VLAN, VLAN termination, Voice VLAN, VLAN mapping, QinQ, GVRP, VCMP, STP/RSTP/MSTP, VBST, SEP, RRPP, ERPS, LBDT, HVRP, and Layer 2 protocol transparent transmission.

Basic Concepts

Basic Concepts

HVRP Concepts

  • HVRP interface

    An interface that is configured with HVRP attributes. It can send, receive, and process HVRP packets.

  • HVRP root interface

    An HVRP interface that functions as the root interface in a Spanning Tree Protocol (STP) region.

  • HVRP designated interface

    An HVRP interface that functions as the designated interface in an STP region.

  • Local VLAN/User VLAN

    A VLAN that does not contain any HVRP interface.

  • VLAN registration

    A process of adding HVRP interfaces to VLANs that meet certain conditions in tagged mode.

  • VLAN aging

    A process of deleting a VLAN from an HVRP interface.

  • Permanent VLAN

    A VLAN that is never aged by an HVRP interface.

  • Local VLAN information sending

    The HVRP root interface sends HVRP packets containing local VLAN information after STP and HVRP are enabled.

  • VLAN registration timer

    A timer that specifies the interval at which HVRP VLAN registration packets are sent.

  • Aging timer of registered VLANs

    A timer that specifies the aging time of registered VLANs. If the HVRP designated interface does not receive any registration packets of a VLAN within the aging time, the VLAN is aged on the HVRP designated interface.

HVRP Packet Format

Figure 21-1 shows the HVRP packet format.

Figure 21-1  HVRP packet format

  • Protocol flag: HVRP packet flag bit.
  • Protocol type: HVRP packet type, which can be user VLAN registration or interface status change notification.
  • MSTI ID: Multiple Spanning Tree Instance (MSTI) ID.
  • Packet content: This field is invalid for interface status change notification packets. In user VLAN registration packets, this field contains information about all authorized user VLANs.
