configuration brigde-group between comware 5940 and dell n3048 over telecom equiment

[gadisontag]

Hello

We are currently trying to get LACP configured from our Hp5940 to a Dell N3048 switch. it's working correctly.

The link is made using transparent boxes of the company

Below is what we have configured.

dell N3048 - ten 1/0/2 + 2/0/2
-------------------------------------

BB-Dell-auto-10.239.11.170#show running-config

interface tengigabitethernet 1/0/2

switchport mode trunk
switchport trunk allowed vlan 507-509

BB-Dell-auto-10.239.11.170#show running-config

interface tengigabitethernet 2/0/2

the problem : If one of the ports falls, the bag does not always detect a fall and communication is lost , The bag does not always know that there is a fall of the line - the second equipment port because there is no direct connection

have any idea ?

Hello

Make sure you create a bridge with LACP. You created a static bridge aggregation. 

You should add on the comware side:

interface Bridge-Aggregation5
link-aggregation mode dynamic

You can use following command to check if you have configured a dynamic or a static bridge aggregation:

dis link-aggregation verbose Bridge-Aggregation 5

On the dell side make sure lacp is configured correctly aswell.

have a new idea

a topholoy :

switch is connect with fiber optic convertor - The port fall will not be detected on the switch, because it gets the link up from the optical converter
