LACP between AIX 7.1 and HP procurve switches
Hi.

On a standalone AIX server, 7.1 version, I have 3 connected gigabit ethernet ports.
I made an etherchannel like this :

Code:
# lsattr -El ent4
adapter_names ent1,ent2 | EtherChannel Adapters True
alt_addr 0x000000000000 | Alternate EtherChannel Address True
auto_recovery yes | Enable automatic recovery after failover True
backup_adapter ent3 | Adapter used when whole channel fails True
hash_mode src_dst_port | Determines how outgoing adapter is chosen True
interval long | Determines interval value for IEEE 802.3ad mode True
mode 8023ad | EtherChannel mode of operation True
netaddr 0 | Address to ping True
noloss_failover yes | Enable lossless failover after ping failure True
num_retries 3 | Times to retry ping before failing True
retry_time 1 | Wait time (in seconds) between pings True
use_alt_addr no | Enable Alternate EtherChannel Address True
use_jumbo_frame no | Enable Gigabit Ethernet Jumbo Frames True

On my HP procurve switch, I set a LACP aggregation link between "ent1" and "ent2" ports of the server.

Here are the result of our tests :
  1. Send data from this server to 2 others servers -> seems to have a real aggregation, with a 2Gbps bandwidth.
  2. Send data from 2 others servers th this one -> seems to have only 1 Gbps bandwidth of network activity on the server.
Have you any idea to have 2 Gbps in both ways ? Does LACP support the aggregation in both ways ? Is there any other way to have 2 Gbps bandwidth ?

Tks.
