Introduction

The following information provides Layer 2 static aggregation configuration examples.

Prerequisites

This document applies to Comware-based access controllers and access points. Procedures and information in the examples might be slightly different depending on the software or hardware version of the access controllers and access points.

The configuration examples in this document were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

This document assumes that you have basic knowledge of H3C Ethernet link aggregation.

Example: Configuring a Layer 2 static aggregation group

Network configuration

On the network shown in Figure 1, perform the following tasks:

·     Configure a Layer 2 static aggregation group on the AC and the switch to increase the bandwidth and improve link reliability.

·     Enable VLAN 10 at one end of the aggregate link to communicate with VLAN 10 at the other end.

·     Enable VLAN 20 at one end of the aggregate link to communicate with VLAN 20 at the other end.

Procedures

Configuring the AC

1.     Configure VLANs:

# Create VLAN 10, and assign port GigabitEthernet 1/0/3 to VLAN 10.

<AC> system-view

[AC] vlan 10

[AC-vlan10] port gigabitethernet 1/0/3

[AC-vlan10] quit

# Create VLAN 20, and assign port GigabitEthernet 1/0/4 to VLAN 20.

[AC] vlan 20

[AC-vlan20] port gigabitethernet 1/0/4

[AC-vlan20] quit

2.     Configure a Layer 2 aggregate interface:

# Create Layer 2 aggregate interface Bridge-Aggregation 1.

[AC] interface bridge-aggregation 1

[AC-Bridge-Aggregation1] quit

# Assign port GigabitEthernet 1/0/1 to link aggregation group 1.

[AC] interface gigabitethernet 1/0/1

[AC-GigabitEthernet1/0/1] port link-aggregation group 1

[AC-GigabitEthernet1/0/1] quit

# Assign port GigabitEthernet 1/0/2 to link aggregation group 1.

[AC] interface gigabitethernet1/0/2

[AC-GigabitEthernet1/0/2] port link-aggregation group 1

[AC-GigabitEthernet1/0/2] quit

# Configure Layer 2 aggregate interface Bridge-Aggregation 1 as a trunk port and assign it to VLANs 10 and 20.

[AC] interface bridge-aggregation 1

[AC-Bridge-Aggregation1] port link-type trunk

[AC-Bridge-Aggregation1] port trunk permit vlan 10 20

[AC-Bridge-Aggregation1] quit

Configuring the switch

1.     Configure VLANs:

# Create VLAN 10, and assign port GigabitEthernet 1/0/3 to VLAN 10.

<Switch> system-view

[Switch] vlan 10

[Switch-vlan10] port gigabitethernet 1/0/3

[Switch-vlan10] quit

# Create VLAN 20, and assign port GigabitEthernet 1/0/4 to VLAN 20.

[Switch] vlan 20

[Switch-vlan20] port gigabitethernet 1/0/4

[Switch-vlan20] quit

2.     Configure a Layer 2 aggregate interface:

# Create Layer 2 aggregate interface Bridge-Aggregation 1.

[Switch] interface bridge-aggregation 1

[Switch-Bridge-Aggregation1] quit

# Assign port GigabitEthernet 1/0/1 to link aggregation group 1.

[Switch] interface gigabitethernet 1/0/1

[Switch-GigabitEthernet1/0/1] port link-aggregation group 1

[Switch-GigabitEthernet1/0/1] quit

# Assign port GigabitEthernet 1/0/2 to link aggregation group 1.

[Switch] interface gigabitethernet 1/0/2

[Switch-GigabitEthernet1/0/2] port link-aggregation group 1

[Switch-GigabitEthernet1/0/2] quit

# Configure Layer 2 aggregate interface Bridge-Aggregation 1 as a trunk port and assign it to VLANs 10 and 20.

[Switch] interface bridge-aggregation 1

[Switch-Bridge-Aggregation1] port link-type trunk

[Switch-Bridge-Aggregation1] port trunk permit vlan 10 20

[Switch-Bridge-Aggregation1] quit

Verifying the configuration

1.     Verify that GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 on the AC are Selected ports in Layer 2 static aggregation group 1.

<AC> display link-aggregation verbose

  GE1/0/1         S       32768     2      None

  GE1/0/2         S       32768     2      None

2.     Verify that the bandwidth for Layer 2 aggregate interface Bridge-Aggregation 1 is the total bandwidth of GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 on the AC.
