Ethernet: What is a jabber timeout

Question

I am writing Ethernet drivers for an STM32 chip. (The reference manual is available here.) At various points, the concept of "jabber timeout" appears, and is not explained. A quick Google search didn't reveal much more information.

What is a jabber timeout?

Answer 1

I did a quick glance at some other datasheets that reference a "jabber timeout".

From the MX98715AEC-C Ethernet chip:

Transmit Jabber Timeout, indicating the MX98715 has been excessively active. The transmit process is aborted and placed in the stopped state. TDES0<1> is also set

I would guess that the timeout setting stops the transmit process if the chip gets into some state where it wont "shut up" (ie it keeps jabbering on and on)

Hope that helps.
