ISIS-MIB

Functions Overview

The draft-ietf-isis-wg-mib-13 defines the ISIS-MIB, which is used to carry out automatic running of related ISIS configurations in the network devices and to record the results. This MIB can provide query for ISIS process, ISIS interface, ISIS counter as well as ISIS alarm.

Root directory:

iso(1).org(3).dod(6).internet(1).experimental(3).isis(37)

A notification sent when we receive a PDU with the wrong authentication type field. This notification includes the header of the packet, which may help a network manager identify the source of the confusion.

To prevent IS-IS excessive trap messages are frequently displayed, you can set the time for suppressing the display of excessive IS-IS trap messages. During the suppression time, the trap message of the specified type is displayed only once, and trap messages of other types are not displayed.

We pass up the size from the option field or the size of the LSP that exceeds our configuration.

To prevent IS-IS excessive trap messages are frequently displayed, you can set the time for suppressing the display of excessive IS-IS trap messages. During the suppression time, the trap message of the specified type is displayed only once, and trap messages of other types are not displayed.
