IBM PowerVM VIOS Load Balance, VLAN, Ethernet Link Aggregation, FAILOVER, Netgear M4300 12X12F

[micael69]

Hello !!!!

Anyone with some experience?

We have 2 IBM VIOS with 4 ports each with speed 10 Gbits on all ports that we want to have with VIOS settings to use Load Balance and FAILOVER and VLAN and Ethernet Link Aggregation.

Customer complains on instablity and networks storms etc, but they have procured thier switches october 2018 and I need to use it.

In IBM VIOS we have:

$ lsdev -dev ent6 -attr

attribute       value               description                                     user_settable

adapter_names   ent2,ent3,ent4,ent5 EtherChannel Adapters                           True

alt_addr        0x000000000000      Alternate EtherChannel Address                  True

auto_recovery   yes                 Enable automatic recovery after failover        True

backup_adapter  NONE                Adapters to use when the primary 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

• In Switch: 
• Src/Dest IP and TCP/UDP Port fields
• Static mode = Disable (should then end up in Dynamic which is Netgear's designation of 802.3AD.

I now that LACP works fine with Cisco without any special VIOS settings, like VIOS settings above, that we now have tried.

Should be very similar with any other industry standard switch.

When you look into the CLI of these switches, you find a very similar syntax as Cisco is using - where both Cisco and Netgear default to LACP for port-channels. What does "show port-channel all" show on the Netgear to start with?

(M4300-12X12F) #show port-channel all

Log. Channel Admin Mbr Device/ Port Port
Intf Name Min Link Mode Type Ports Timeout Speed Active
------- --------------- ---- ------ ------ ---- ------- ------------- --------- -------
lag 1 WhateverLAG 1 Down En. Dyn. 1/0/1 actor/long 10G Full False

...

In case it's on static...

(M4300-12X12F) (Config)#port-channel load-balance 6 0/13/1

(M4300-12X12F) (Config)#interface 1/0/1-1/0/4

(M4300-12X12F) (Interface 1/0/1-1/0/4)#addport lag 1

1/0/1 interface is part of a port-channel.
1/0/2 interface is part of a port-channel.

1/0/3 interface is part of a port-channel.
1/0/4 interface is part of a port-channel.

(M4300-12X12F) (Interface 1/0/1-1/0/4)# port lacpmode

...

One point hitting my eyes (not relevant for now - more a performance thing) are the very different hash algorithms on the switch vs. the IBM VIOS side.
