Link-agregation Load-sharing mode - packet type-based sharing?

[headache_dc]

Hello.

On HPE 5130 use the command 'displ link-aggregation load-sharing mode' to find out current load-sharing algorithm and see this:

!

<5130>displ link-aggregation load-sharing mode
Link-aggregation load-sharing mode:
Layer 2 traffic: packet type-based sharing
Layer 3 traffic: packet type-based sharing

What does packet type-based sharing mean?

Thanx.

As command:

link-aggregation global load-sharing mode { destination-ip | destination-mac | destination-port | ingress-port | source-ip | source-mac | source-port }

shows, LACP load-sharing mode could be set in a way that traffic can be "load-shared across selected ports" based on a per-flow basis, that way load-sharing mode classifies packets into flows and forwards packets of the same flow on the same link.

Load-sharing mode can be one of or a combination of the following traffic classification criteria (for HPE 5130):

• Ingress Port
• Source or Destination IP Address
• Source or Destination MAC Address
• Source or Destination Port Number

Thanks for reply.

But I'm still confused which criteria switch used to classify packets to flows if I have not configured 'link-aggregation global load-sharing' command.

Your switch has default values: directly from the HPE FlexNetwork 5130 EI Switch Series - Layer 2 LAN Switching Configuration Guide for R32xx "By default, the device automatically determines the load sharing mode depending on the
packet type." [*] (and that's the global default) and "By default, group-specific load sharing mode is the same as the global load sharing mode"...so if you don't specify nothing at group specific level the load sharing mode fallbacks to the global default.

[*] That's the second mode I didn't mentioned on my previous answer, the "Packet type-based load sharing" which distributes traffic automatically based on packet types (Layer 2 protocol, IPv4, or IPv6).

When we come to the forum, we are looking for a better interpretation of what is given or what we already read on the official guide.  I don't know how it helps when someone only copy and paste what we know.  At least, I read the guide 1^st and if I am lost, I come here for more brilliant answers, but not to see the same again and again.

Thanks for your effort anyway, some other users might find this kind of answers ok.
