RMON Extensions Application

Protocol

Displays the protocol used to monitor the device. Writing to the address field causes a default protocol value, derived from the format/content of the address, to be setup. If the protocol is not supported or is not compatible with the address, an error is returned when the status is set to valid. Possible values are unknown, ip, ipx, netBIOS, appleTalk, and amp.

Timeout

Displays the time-out value in hundreds of a second for each request packet.

Attempt

Displays the number of unsuccessful requests necessary before deciding that the device is not responding.

Period

Displays how often the device will be polled, in seconds. The first poll is sent as soon as the status becomes valid.

Last Request

Displays the time, counting from the last system reset, at which the most recent request packet was sent.

LastReply

Displays the time, counting from the last system reset, at which the most recent request packet was received.

Information

After each poll, this field is updated with protocol-specific information from the packet exchange. For the IPX protocol, this displays the number of router hops made by the poll response packet. For the IP protocol, this displays the value of Time-To-Live from the IP packet header.

Success Index

Displays the index of the event that is used when a successful poll is made after a number of unsuccessful ones. If this value is zero, no event will be generated.

Failure Index

Displays the index of the event that is used when an unsuccessful poll is made after a number of successful ones. If this value is zero, no event will be generated.

Owner

Displays the owner of the device. RMON OwnerString conventions are used here to help control multi-manager situations.

Status

Displays the creation or deletion status of entries in the PollTable. RMON EntryStatus conventions are used.
