Hello 3COM community!



I try to setup static(dynamic) link aggregation between 4500(3CR17562-91)and 4500G(3CR17761-91)



We used the following Manuals - 3Com_Switch_4500G_Config_Guide_V05.02.00 and 3Com_Stackable_Switch_Advanced_Config_Guide



Dynamic link-aggregation example

4500 config:

#

port link-type trunk

port trunk permit vlan 1 100

#

#

interface Vlan-interface100

ip address 192.168.0.3 255.255.255.0

#

interface GigabitEthernet1/0/23

port link-type trunk

port trunk permit vlan 1 100

broadcast-suppression pps 3000

undo jumboframe enable

port link-aggregation group 1

#

interface GigabitEthernet1/0/24

port link-type trunk

port trunk permit vlan 1 100

broadcast-suppression pps 3000

undo jumboframe enable

In this case 4500 cannot ping 4500G. Whats the problem ?

I would configure LACP on both switches or configure it manually on both switches.. Not lacp one one and manual on the other.

For manual dont forget the "link-aggregation group 1 mode manual" command in global mode. Futher use "speed 1000" and "duplex full" on the interfaces. Make sure you have no cables connected while configuring this.

Hello richardkok !



Thanks for your replay.



As can be seen from config examples dynamic linkaggregation was implemented. I try to setup speed 1000 and duplex full on both switches - no result.

When links up i see next messages in console log:

LACP is not enabled on 4500G switch. I am at a loss :quest:

That is exactly the problem. You have configured LACP on your 4500 switch but you have NON-LACP on your 4500G. That is why you get the messages like :



%Apr 4 17:09:55:434 2000 4500 LAGG/3/PartnerNoLacp:- 1 -LACP is not enabled on the remote end of port GigabitEthernet1/0/50.

%Apr 4 17:09:57:195 2000 4500 LAGG/3/PartnerNoLacp:- 1 -LACP is not enabled on the remote end of port GigabitEthernet1/0/49.



You should enable LACP on the 4500G as well.. OR.... config both end as NON-LACP... thus manual aggregation

Text from 4500G Release notes:



2.2.1. Link Aggregation – LACP (IEEE 802.3ad)

Dynamic LACP has been removed. LACP is only supported with static link-aggregation groups. There is more information on this in the “Chapter 4- Upgrading Software†, sections Dynamic LACP Aggregated Links and “Chapter 6- Converting dynamic aggregated links to static aggregated links†.

and...

4.2. Dynamic LACP Aggregated Links

Dynamic LACP (IEEE 802.3ad) has been removed from V5.01.03. LACP (IEEE 802.3ad) can be used with static aggregated links. If dynamic links are configured, convert them to static aggregated links before updating to V5.01.03. This link to 3KB Document ID: 3KB21594, alias “Chapter 6- Converting dynamic aggregated links to static aggregated links†provides information on how to determine if dynamic link aggregation groups are configured and how to convert a dynamic link aggregation group to a static link aggregation group.



it seems it is not possible...

Ok, well...

I try static link aggregation mode. No positive results :mad:



Small quota from Advanced config guide for 4500:



1) In manual aggregation mode # Create manual aggregation group 1. <SWITCHA> system-view link-aggregation group 1 mode manual # Add Ethernet 1/0/1 through Ethernet 1/0/3 to aggregation group 1. interface Ethernet1/0/1 port link-aggregation group 1 quit interface Ethernet1/0/2 port link-aggregation group 1 quit interface Ethernet1/0/3 port link-aggregation group 1 2) In static LACP aggregation mode # Create static aggregation group 1. <SWITCHA> system-view link-aggregation group 1 mode static







No sense to try "static LACP aggregation mode" because LACP was removed from 4500G



Example with mode manual(static) with no result.
