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

this is my configuration on second stack:
<Core-SW>display current-configuration interface Bridge-Aggregation 10
#

port trunk permit vlan all
link-aggregation mode dynamic
#
