  • 1.  Disable a port on an Enterasys / Extreme S4

    At some point I remember the need to turn on a feature on the S4, so when you disable a port (set port disable tg.3.1), it actually stops processing packets for that port. I thought it was a global command, but I can't remember. Maybe they changed it with newer version of code. Anyway, I'm just curious.

    Thanks

    Actually, I may have found it. I think it might be the set forcelinkdown feature.

    Hi Jeremy,

    That is correct, when you administratively disable a port with 'set forcelinkdown' enabled, the link will be brought down as well.

    Hello Jeremy,

    We have also documented this in our Knowledge article Port link stays up when port is disabled available here:

    Hi Jeremy,
    Also a good possibility -

    "set spantree portenable ge.1.1 disable"

    toggles bridging on/off for port ge.1.1.

    Sometimes handy but rarely used these days - and easily confused with the command to toggle the spanning tree algorithm on a port. (set spantree portadmin ge.1.1 enable|disable)
