router with stacking Alcatel 6850 support

[cablenet]

Hello i would me to know if my config used on stack two Alcatel 6850E with LACP/Static LAG by 4-8G is alright.

i need routing inter-vlan throughput 3-4G.

my config:

chassis 1:
static agg 1/11 agg num 1
static agg 1/12 agg num 1
static agg 1/13 agg num 1
chassis 2:
static agg 2/11 agg num 1
static agg 2/12 agg num 1
static agg 2/13 agg num 1

LACP
chassis 1
lacp agg 1/6 actor admin key 5
lacp agg 1/7 actor admin key 5
lacp agg 1/8 actor admin key 5
lacp agg 1/9 actor admin key 5

chassis 2
lacp agg 2/6 actor admin key 5
lacp agg 2/7 actor admin key 5
lacp agg 2/8 actor admin key 5
lacp agg 2/9 actor admin key 5


vlan 50 802.1q 1 "TAG PORT VLAN 50"
vlan 60 802.1q 1 "TAG PORT VLAN 60"
vlan 90 802.1q 1 "TAG PORT VLAN 90"

vlan 10 802.1q 2 "TAG PORT VLAN 50"
vlan 20 802.1q 2 "TAG PORT VLAN 60"
vlan 30 802.1q 2 "TAG PORT VLAN 90"

ip interface "vlan_10" address 10.0.40.1 mask 255.255.255.0 vlan 10 ifindex 36
ip interface "vlan_20" address 10.0.44.1 mask 255.255.255.0 vlan 20 ifindex 37
ip interface "vlan_30" address 10.0.45.1 mask 255.255.255.0 vlan 30 ifindex 38

ip interface "vlan_50" address 10.0.46.1 mask 255.255.255.0 vlan 50 ifindex 39
ip interface "vlan_60" address 10.0.47.1 mask 255.255.255.0 vlan 60 ifindex 40
ip interface "vlan_90" address 10.0.48.1 mask 255.255.255.0 vlan 90 ifindex 41

when i try routing inter-vlan the is 1G, and don't work with 3-4G of throughput

any idea.

regards.

As with all LACP/Aggregation the maximum thgroughput per flow is limited to bandwidth of one link.
You can max out only when having different communications (per default sorce/dest-mac?) between two hosts it will always be 1G only. Try with 10 hosts at the same time!

i don't understand the static agg in your config.. why? Where do you configure the LACP ?
lacp linkagg 1 size 4 admin state enable
lacp linkagg 1 actor admin key 5
lacp agg 1/6 actor admin key 5
lacp agg 1/7 actor admin key 5
lacp agg 1/8 actor admin key 5
lacp agg 1/9 actor admin key 5

(omitting that may work with a single lacp, but makes problems when you have more connections.)
