How to configure Layer 3 Aggregate Port (Static and Dynamic)?

I. RequirementsEnable Layer 3 AP on the ports between two Core switches to expand inter-connection bandwidth and ensure a high available network. Use src-dst-IP load balance method. II. Network Topology                                             https://img.sobot.com/console/eee7ec2e351e4569a4791536fb5f0973/kb/image/efe9f0cfb26949b696c27afa656b77c7.png III. Configuration Tips1. First, you must create a AP and convert it to a L3 AP, then assign a IP address to it.2. Convert AP members to L3 ports.3. Put the AP members in the AP4. Modify load balance methodNote：You must follow the tips above step by step ,otherwise you could fail to configure L3 AP. IV. Configuration StepsSW1：SW1>enableSW1#configure terminalSW1(config)#interface aggregateport 1SW1(config-if-AggregatePort 1)#no switchport                                    ------>convert AP 1 from L2 to L3SW1(config-if-AggregatePort 1)#ip address 1.1.1.1 255.255.255.0 SW1(config-if-AggregatePort 1)#exitSW1(config)#interface range gigabitEthernet 0/23-24                        ------>configure a range of interfaces with the same commandsSW1(config-if-range)#no switchport                                                    ------>convert AP members to layer 3SW1(config-if-range)#medium-type fiberSW1(config-if-range)#port-group 1 mode active                                  ------>put G0/23 and G0/24 in AP 1 in active modeSW1(config-if-range)#exitSW1(config)#aggregateport load-balance src-dst-ip                  ------>put G0/23 and G0/24 in AP 1 in active mode ------------------------------------------------------------------------------------------orSW1(config-if-range)#port-group 1                                                    ------>put G0/23 and G0/24 in AP 1 in static modeSW1(config-if-range)#end SW2：SW2>enableSW2#configure terminalSW2(config)#interface aggregateport 1SW2(config-if-AggregatePort 1)#no switchportSW2(config-if-AggregatePort 1)#ip address 1.1.1.2 255.255.255.0SW2(config-if-AggregatePort 1)#exitSW2(config)#interface range gigabitEthernet 0/23-24SW2(config-if-range)#no switchportSW2(config-if-range)#medium-type fiberSW2(config-if-range)#port-group 1 mode activeSW2(config-if-range)#endSW2(config)#aggregateport load-balance src-dst-ip ----------------------------------------------------------------------------------------orSW2(config-if-range)#port-group 1SW2(config-if-range)#end V. Verification1. When both ends negotiate to join a AP successfully, system returens the following message:*Dec 17 13:23:52: %LLDP-4-ERRDETECT: Link aggregation for the port GigabitEthernet 0/23 may not match with one for the neighbor port.*Dec 17 13:23:52: %LLDP-4-ERRDETECT: Link aggregation for the port GigabitEthernet 0/24 may not match with one for the neighbor port.*Dec 17 13:23:59: %LACP-5-ATTACH: Interface GigabitEthernet 0/23 attached to AggregatePort 1.*Dec 17 13:23:59: %LACP-5-ATTACH: Interface GigabitEthernet 0/24 attached to AggregatePort 1.*Dec 17 13:24:00: %LACP-5-BUNDLE: Interface GigabitEthernet 0/23 joined AggregatePort 1.*Dec 17 13:24:00: %LACP-5-BUNDLE: Interface GigabitEthernet 0/24 joined AggregatePort 1.*Dec 17 13:24:02: %LINK-3-UPDOWN: Interface AggregatePort 1, changed state to up.*Dec 17 13:24:02: %LINEPROTO-5-UPDOWN: Line protocol on Interface AggregatePort 1, changed state to up. 2.
