Description: This object contains the number of times that automatic rate adaption events have occurred.

What is cmmARAEvents?

This read-only counter tracks how many times automatic rate adaptation, where the modem adjusts its connect speed in response to changing line conditions, has occurred. Admins use this to gauge how often a given line required the modem to dynamically step its rate up or down, an indicator of marginal or fluctuating line quality. For example, a session showing several cmmARAEvents entries would suggest the connection experienced changing conditions requiring the modem to repeatedly adjust its rate rather than holding one steady speed throughout.

Examples

Walk all instances (SNMPv2c):
