Trunk between 4800G and 4500G goes down

When I try to setup a trunk with aggregation between a 4500G and 4800G, the trunk goes down. Below are the configuration of both switches.

 

4500G

 

inter bridge aggregation 1

link-aggregation mode dynamic

description trunk 4500-4800

 

interface giga 1/0/49

port link-aggregation group 1

port link-type trunk

port trunk permit vlan all

 

interface giga 1/0/50

port link-aggregation group 1

port link-type trunk

port trunk permit vlan all

 

4800G

 

link-aggregation load-sharing mode destination-mac source-mac

inter bridge aggregation 2

description trunk 4800-4500

 

interface giga 1/0/49

port link-aggregation group 2

port link-type trunk

port trunk permit vlan all

 

interface giga 2/0/49

port link-aggregation group 2

port link-type trunk

port trunk permit vlan all

 

 I modified the 4800 configuration of the bridge to dynamic mode without success...

 

Any suggestion will be welcome

Regards, Hector

hi ducheus

 

You have to configure the trunk on the bridge-aggregation. Else there is a missmatch between the bridge interface and the physical interface and the bridge will not come up.

 

and sync the LACP-mode. remove or add the dynamic on both switches.
