LACP / BAGG query on Comware 7

  • 1.  LACP / BAGG query on Comware 7

    Posted Jan 11, 2023 03:29 AM
    Hi,

    I have a 20Gb BAGG configured between a 10504 and 5945 IRF pair. The BAGG has successfully negotiated at 20Gb and both appear to be passing traffic albeit 1 link more than the other. I noticed that one of the 4 links has "lacp period short" configured on the interface (not sure how), but when you look at the BAGG on this particular link the LACP flag (B I think) is missing.

    Can I remove the lacp period short command without disrupting traffic?

    It might be worth mentioning that this BAGG is stretched between 2 sites via a fibre and extends our DC between sites for migration services as one is closing. Also, if I shut down one of the interfaces will this cause issues or will TCP just resend over the other link ?

    Thanks,

    Matt.

    lacp period should be the same on both sides and on all ports inside BAGG group.

    There should be no ill effects if you shutdown one port inside the BAGG group. Traffic should pass uninterrupted over other available ports.
    But still it is good practice to do it during quiet periods.

    Hope this help, Gorazd

    Hi Gorazd,

    Thanks for confirming, I was able to shut down one of the Bridge Aggregation interfaces with no disruption :)

    Thanks,

    Matt.
