What is LAG interfaces used for on 6300 Switches

    Hello Sirs,
    Hope you are all very well and keeping safe.
    Please what is the LAG used for on the above switches. What I know is it is an etherchannel in Cisco equipment. However, I found this on the above switch interface but the other end connecting to a Cisco ASA firewall did not have any etherchannel configured.

    We removed the LAG12 on the interface of the 6300 and lost connectivity. 

    Can anyone help me understand what this is for.
    Thanks

    Etherchannel is Cisco proprietary.
    Ethernet link aggregation bundles multiple physical Ethernet links into one logical link, called a link aggregation group (LAG).
    You can read more about it here

    Well done sir, this explains it all for me.
    In other words LAG configuration on switch A will be on switch B as well right?
    Thanks

    Hello Danny,

    "In other words LAG configuration on switch A will be on switch B as well right?"

    It doesn't "will", it does "shall": a LAG on a Peer A requires another characteristics-matching LAG on the Peer B otherwise the aggregated interfaces will not work as you expect.
