Title: How to configure Layer 2 Aggregate Port (Static and Dynamic)?

I. Requirements

Enable Layer 2 AP on the ports between two Core switches to expand inter-connection bandwidth and ensure a high available network. Use src-mac load balance method.

II. Network Topology

III. Configuration Tips

1. Put AP members ports in a specified AP

2. Configure AP as Trunk

3. Modify load balance method

IV. Configuration Steps

Static mode:

SW1：

SW1>enable

SW1#configure terminal

SW1(config)#interface range gigabitEthernet 0/1-2 ------>configure a range of interfaces with the same command

SW1(config-if-range)#port-group 1 ------>put G0/1 and G0/2 in AP 1 in static mode

SW1(config-if-range)#exit

SW1(config)#interface aggregateport 1

SW1(config-if-AggregatePort 1)#switchport mode trunk ------>configure AP 1 as Trunk

SW1(config-if-AggregatePort 1)#exit

SW1(config)#aggregateport load-balance src-mac ------>modify load balance method to Src-MAC. By default, it is Src-Dst-MAC.

SW1(config)#exit

SW1#wr

SW2：

SW2>enable

SW2#configure terminal

SW2(config)#interface range gigabitEthernet 0/1-2

SW2(config-if-range)#port-group 1

SW2(config-if-range)#exit

SW2(config)#interface aggregateport 1

SW2(config-if-AggregatePort 1)#switchport mode trunk

SW2(config-if-AggregatePort 1)#exit

SW2(config)#aggregateport load-balance src-mac

SW2(config)#exit

SW2#wr

Dynamic mode:

SW1(config)#interface range gigabitEthernet 0/1-2

SW1(config-if-range)#port-group 1 mode active ------>put G0/1 and G0/2 in AP 1 in dynamic mode

SW1(config-if-range)#exit

SW1(config)#interface aggregateport 1

SW1(config-if-AggregatePort 1)#switchport mode trunk ------>configure AP 1 as Trunk

SW1(config-if-AggregatePort 1)#exit

SW2 is the same.

3. This example shows how to configure L2 AP in static mode when connect Ruijie a switch to a Cisco switch

Cisco：

interface Port-channel1

switchport mode access

interface FastEthernet0/1

switchport mode access

channel-group 1 mode on

interface FastEthernet0/2

switchport mode access

channel-group 1 mode on

Ruijie :

interface AggregatePort 1

interface FastEthernet 0/1

port-group 1

interface FastEthernet 0/2

port-group 1

4. This example shows how to configure L2 AP in dynamic mode when connect Ruijie a switch to a Cisco switch

Cisco：

interface Port-channel1

switchport mode access

interface FastEthernet0/1

switchport mode access

channel-group 1 mode active

interface FastEthernet0/2

switchport mode access

channel-group 1 mode active

Ruijie :

interface FastEthernet 0/1

port-group 1 mode active

interface FastEthernet 0/2

port-group 1 mode active

interface AggregatePort 1

V. Verification

1. How to display status of aggregate port

2. How to display information of AP 1

3. How to display the load balance method
