HP A5500-24G-4SFP Bridge-Aggregation LACP

Hello ,

 

I have packet loss when I enable link aggrigation on HP switch .

4 switches that connected via two stacks .

when i shutdown one of the links , i do not have any packet loss and internet works fine .

 

this is my configuration on first stack:

 

<CORE01>display current-configuration interface Bridge-Aggregation 10
#
interface Bridge-Aggregation10
 port link-type trunk
 port trunk permit vlan all
 link-aggregation mode dynamic
#
return

 

<CORE01>display current-configuration interface GigabitEthernet 1/0/4
#
interface GigabitEthernet1/0/4
 port link-mode bridge
 port link-type trunk
 port trunk permit vlan all
 lacp period short
 port link-aggregation group 10
#
return

 

<CORE01>display current-configuration interface GigabitEthernet 2/0/4
#
interface GigabitEthernet2/0/4
 port link-mode bridge
 port link-type trunk
 port trunk permit vlan all
 lacp period short
 port link-aggregation group 10
#
return

 

 

this is my configuration on second stack:

 

<Core-SW>display current-configuration interface Bridge-Aggregation 10
#
interface Bridge-Aggregation10
 port link-type trunk
 port trunk permit vlan all
 link-aggregation mode dynamic
#
return

 

<Core-SW>display current-configuration interface GigabitEthernet 1/0/42
#
interface GigabitEthernet1/0/42
 port link-mode bridge
 port link-type trunk
 port trunk permit vlan all
 lacp period short
 port link-aggregation group 10
#
return

 

<Core-SW>display current-configuration interface GigabitEthernet 2/0/42
#
interface GigabitEthernet2/0/42
 port link-mode bridge
 port link-type trunk
 port trunk permit vlan all
 lacp period short
 port link-aggregation group 10
#
return

 

what might be the problem ?

ok .. we figure it out .. there was a block role on our ISP infrastructure .. they was blocking the 802.3ad protocol
