ATMLOOP(8)

✨ ATMLOOP(8) ✨

okay bestie, so this is atmloop, and it lives in the Maintenance Commands corner of the ATMLOOP(8) manual. she's giving utility, she's giving diagnostics, she's lowkey the girl who can make your ATM interface yell its own echo back at itself 💅

🌸 NAME 🌸

atmloop — get/set loopback mode of ATM interfaces 🦋

🎀 SYNOPSIS 🎀

atmloop -s [-l level] [-r level] [itf]
atmloop [itf]
atmloop -q [itf]
atmloop -V

💖 DESCRIPTION 💖

so what does she actually do. atmloop sets or shows the current loopback settings of an ATM interface, and — icon behaviour honestly — she also lets you query which loopback modes the interface even supports. vibe check first, actions second, we love a planner ✨

some ATM cards can be configured to echo data back to the driver (that's local loopback) or back out to the network (that's remote loopback). and the echoing? it can happen at several different levels, bestie, like a whole ladder of echo:

• aal — AAL PDUs
• atm — ATM cells
• digital — bits sent to or received from the line interface
• analog — the analog signal

the levels an interface supports can be queried with the -q option 👑

and if you invoke her with no options at all? she just displays the current loopback settings. no notes, just facts 🫶

✨ OPTIONS ✨

• -s — set loopback mode. follow it with either -l or -r, or with both of them to set local and remote loopback at the same time (only if the driver supports that, no cap), or with neither of them to turn off any loopback. it's giving off switch energy 💀
• -l level — enable local loopback.
• -r level — enable remote loopback.
• -q level — query loopback levels supported by the interface.
• -V — print version number of atmloop on standard output and exit. short, sweet, slays, periodt ⭐
