HPE Aruba 3810 and 2930 SFP+ trunking...

    Posted Nov 27, 2018 08:04 AM

    We have the following switches:

    1x Aruba 3810M-16P (JL075A)
    1x Aruba 3810M-48P (JL072A)

    4x Aruba 2930F (JL254A)

    The JL075A and JL072A have a separate SFP + module (JL083A) 4x10 Gpbs
    I would like to connect the switches via SFP + together.

    The JL075A to JL072A via the SFP + module
    The JL254A on the JL075A via the SFP + port

    I want to use at least two ports per switch to realize the uplink.
    All servers are connected to the Fiber Switch JL075A via AOC cables
    The JL072A works as a core switch

    We have 6 vlans. It is intended that these can co-exist with each other except the guests subnet VLAN30

    My question is:
    Should i use port trunking or LACP?

    For example:
    trunk 45-46 LACP?
    or
    trunk 45-46 trunk?

    Or better advice so that I can make maximum use of the bandwidth.

    Thanks.

    Yes, you should. LACP Trunks help your uplinks to gain in resiliency and traffic (re)distribution.

    The correct syntax is trunk 45-46 trk1 lacp, that way interface 45 and 46 will be physical member interfaces of LAG (Link Aggregation Group) named trk1 using LACP.
