    Posted Feb 11, 2021 12:58 PM
    Hi Guys,

    I wonder if anybody had anything similar and can help me to resolve the issue.
    I have Cisco 9200L stack 16.12.4 and Aruba switch 2930F.
    Connected with SFP/fiber.
    Cisco keeps telling me

    Feb 11 03:28:26.051: %ETC-5-L3DONTBNDL2: Gi1/1/1 suspended: LACP currently not enabled on the remote port.

    Feb 11 03:28:26.815: %ETC-5-L3DONTBNDL2: Gi2/1/1 suspended: LACP currently not enabled on the remote port.

    The interfaces on the Aruba side simply Link Down.
    Spanning tree - MST on both sides.
    Fiber cables multimode and checked.
    SFPs in use: GLC-LH-SMD and 1000-Base-SX

    Ports configuration below:
    Cisco

    interface GigabitEthernet1/1/1

    switchport trunk allowed vlan 2300-2316

    switchport mode trunk

    speed nonegotiate

    channel-group 1 mode active

    interface GigabitEthernet2/1/1

    switchport trunk allowed vlan 2300-2316

    switchport mode trunk

    speed nonegotiate

    channel-group 1 mode active


    interface Port-channel1

    switchport trunk allowed vlan 2300-2316

    switchport mode trunk

    Aruba

    interface 51

       speed-duplex 1000-full

       untagged vlan 1

       trunk trk2 lacp

    interface 52

       speed-duplex 1000-full

       untagged vlan 1

       trunk trk2 lacp

      

    interface Trk2

       tagged vlan 2300-2316

       untagged vlan 1

       spanning-tree priority 4

       exit

    Aruba switch output:
    Load Balancing Method: L3-based (default)

    Port | Name Type | Group Type
    ------ + -------------------------------- ---------- + ----- --------

    51 | ===Name=== 1000SX | Trk2 LACP
    52 | ===Name=== 1000SX | Trk2 LACP


    LACP Trunk Port LACP Admin Oper

    ----- ------- ------- ------- ------- ------- ------ ------

    52 Active Trk2 Down No Success 0 533


    Thanks in advance,

    What do you have on Aruba log ?

    why you have disable auto negotiation ?

    Try this

    configuration of TRUNK Cisco ports between switches:

    switchport trunk encapsulation dot1q

    switchport mode trunk

    switchport nonegotiate

    spanning-tree link-type point-to-point

    Hi Maxime,

    I just found out.
    The SFPs have different wavelength. :(
    The devil is really in the details.

    Kind regards,
    Paul

    Yeah...never interconnect a Long Haul transceiver (LH/LX = operates on standard single-mode fiber-optic link spanning up to 10 km and up to 550 m on any multimode fibers) with a Short Range (SR/SX = operates in multi-mode fiber-optic link spanning generally less than 300/500 meters) transceiver...central wavelengths are necessarily different (850 nm vs 1310/1550 nm)!

    Read the good Aruba AOS-Switch and AOS-CX Transceiver Guide (Edition 10) to understand essential differences about various transceivers.

    Hi Alagoutte,

    Aruba log is empty.
    No messages related to the connection at all.
    I tried with and without auto negotiation.
    I even tried a simple trunk connection between the switches.
    Aruba side stil Link-Down.
    I wonder if there's a way to check the SFPs?
    May the GLC-LH-SMD and 1000-Base-SX aren't compatible?

    Kind regards,
    Paul
