DESCRIPTION
|
|
"This table is used to provide remote device monitoring facilities.
|
|
|
|
The implementation allows a list of network devices to be set up
|
|
and polled regularly (or only once) by a variety of protocols.
|
|
The table can be configured to inform the management station(s)
|
|
of devices that are not responding to polls or that have started
|
|
to respond after a period of silence.
|
|
|
|
The minimum effort required to do a single poll is
|
|
1. In one packet, write the address and set a3ComPollAction to
|
|
activate(2).
|
|
2. In the next packet, read the a3ComPollReport.
|
|
|
|
The minimum effort required to monitor a device is
|
|
1. In one packet, write the address, set a3ComPollAttempts to 1,
|
|
set a3ComPollCount to 0 and set a3ComPollAction to activate(2).
|
|
2. Wait for traps to come in.
|
|
|
|
A row in this table is created by setting any read-write member,
|
|
indexed by the next available index (a3ComPollNextFreeIndex). This
|
|
method of creation makes the table very user friendly, although
|
|
a bit harder to detect racing conditions. The suggested method for
|
|
racing condition detection is by checking the a3ComPollAddress and
|
|
a3ComPollOwner objects while the a3ComPollReport object is set to
|
|
active. An example of the indexing of this table is a3ComPollRate.2"

DESCRIPTION
|
|
"This defines the method used to interpret the a3ComPollAddress,
|
|
which implies on the protocol to be used.
|
|
|
|
Writing an address to the a3ComPollAddress object causes a default
|
|
a3ComPollAddressType value to be setup. The default value is
|
|
derived from the format of the address - four octets means ip(2),
|
|
four sets of numeric values separated by dot means ipdotted(3), eight
|
|
and twelve octets separated by colon means ipx(5), and two sets of
|
|
numeric values separated by a dot means appletalk(6). If the address
|
|
type cannot be figured out, and this object is not currently set to
|
|
ipname(4), it will then be set to unknown(1). In other words, this
|
|
object will remain unchanged if its current value is ipname(4) and
|
|
a more specific type cannot be given to it. Thus, for the mot part,
|
|
when setting this object manually, that needs to be done after
|
|
setting a3ComPollAddress.
|
|
|
|
For ip hostname(4), this field must be set manually. Furthermore,
|
|
DNS client must be locally enabled to allow for conversion from name
|
|
to ip address.
|
|
|
|
If the requested protocol is not supported or is not compatible
|
|
with the a3ComPollAddress, an error is returned when an attempt is
|
|
made to set a3ComPollAction to activate(2), and a3ComPollReport will
|
|
be set to noResource(4).

This object may not be modified if the associated a3ComPollReport

a3ComPollAddressType - the type of the address above.
|
|
a3ComPollAttempts - number of replies received in sequence before

this trap was triggered.

a3ComPollRate - rate at which device is being polled. 0 = burst.
|
|
a3ComPollFramesSent - total number of frames sent.
