I've just setup lagg on one of our servers and run some
basic tests and although everything seems to be reporting
correctly no balancing appears to be happening.
The following is the setup:
FreeBSD side:
ifconfig_em0="up"
ifconfig_em1="up"
cloned_interfaces="lagg0"
ifconfig_lagg0="laggproto lacp laggport em0 laggport em1"
ipv4_addrs_lagg0="10.10.1.66/24"
Cisco side:
interface Port-channel2
description SERVER:: test - lagg0
switchport
switchport access vlan 96
switchport mode access
no ip address
end
interface GigabitEthernet3/35
description SERVER:: test - em0
switchport
switchport access vlan 96
switchport mode access
no ip address
channel-protocol lacp
channel-group 2 mode active
end
interface GigabitEthernet3/43
description SERVER:: test - em1
switchport
switchport access vlan 96
switchport mode access
no ip address
channel-protocol lacp
channel-group 2 mode active
end
Config:-

Anyone got any ideas, as far as I can see lacp is negotiating correctly just
no balancing is happening :(
