LACP setting on Aruba 5406R with VSF

  • 1.  LACP setting on Aruba 5406R with VSF

    Posted Jun 29, 2021 01:49 PM

    I have 2 Aruba 5406R connected to each other by VSF. And aim to have some servers connect to the switches using LACP. 

    For example Server A eth-1 connects to Commander switch, eth-2 connects to Standby switch. On the server side, I have set LACP teaming of eth-1 & 2 with dynamic load balancing. Is there anything I have to set in the switch side? like LACP trk or port channel?

    Thank you very much

    VSF side it is enough to configure a Port Trunking (link aggregation) and setup it with LACP.

    As example, if you want to create a LAG interface "trk1" made of two physical interfaces 1/A1 and 2/A1 and use LACP:

    trunk 1/A1,2/A1 trk1 lacp

    Once trk1 is created (check with show trunks, show lacp) you can then adapt its untagging/tagging like you normally do on a physical interface (it propagates to its member ports).

    Hi Davide,


    Thank you for the suggestion.

    May I know what is the different between LACP trunk and port channel please?

    Thank you.

    Hi! it's a matter of jargons and different ones are used by different vendors (let we consider, as example, what happened with Cisco versus HP E series, aka HP ProCurve): Port Channel, EtherChannel, Port Bonding, Teaming, Port Trunking, LAG, Link Aggregation, etc.

    I'm simplifing..the old HP E series (running HP ProVision operating system), now rebranded HPE Aruba (running ArubaOS-Switch operating system), uses the Port Trunking terminology to indicate the aggregation of two or more (generally up to 8) physical links under specific requirements/restrictions...and such of Port Trunking can be Non-Protocol (static = type trunk) or LACP (dynamic = type lacp).

    Unfortunately Cisco adopted the "trunk" term to specify a port capable of transporting more VLANs and this created confusion when HP used the same term on Port Trunking to designate not only a completely different feature (Links Aggregation) but also an option (type trunk means static) for that very feature.

    Generally using Links Aggregation is more misunderstandings prone...so when you read, as example, ports bonding or ports teaming you should re-read it as Links Aggregation and, as said, this one can be non protocol (Static) or protocol (LACP) driven/controlled.
