DESCRIPTION
|

|
"This reports the status of a peer entry.
|
||
|
A value of valid indicates a normal entry
|
||
|
that is in use by the agent. A value of
|
||
|
underCreation indicates a newly created
|
||
|
entry which isn't yet in use because the
|
||
|
creating management station is still setting
|
||
|
values.
|
||
|
|
||
|
The value of invalid indicates the entry is
|
||
|
no longer in use and the agent is free to
|
||
|
delete the entry at any time. A management
|
||
|
station is also free to use an entry in the
|
||
|
invalid state.
|
||
|
|
||
|
Entries are created by setting a value of
|
||
|
createRequest. Only non-existent or invalid
|
||
|
entries can be set to createRequest. Upon
|
||
|
receiving a valid createRequest, the agent
|
||
|
will create an entry in the underCreation
|
||
|
state. This object can not be set to a
|
||
|
value of underCreation directly, entries can
|
||
|
only be created by setting a value of
|
||
|
createRequest. Entries that exist in other
|
||
|
than the invalid state can not be set to
|
||
|
createRequest.
|
||
|
|
||
|
Entries with a value of underCreation are
|
||
|
not used by the system and the management
|
||
|
station can change the values of other
|
||
|
objects in the table entry. Management
|
||
|
stations should also remember to configure
|
||
|
values in the mioxPeerEncTable with the same
|
||
|
peer index value as this peer entry.
|
||
|
|
||
|
An entry in the underCreation state can be
|
||
|
set to valid or invalid. Entries in the
|
||
|
underCreation state will stay in that state
|
||
|
until 1) the agent times them out, 2) they
|
||
|
are set to valid, 3) they are set to
|
||
|
invalid. If an agent notices an entry has
|
||
|
been in the underCreation state for an
|
||
|
abnormally long time, it may decide the
|
||
|
management station has failed and invalidate
|
||
|
the entry. A prudent agent will understand
|
||
|
that the management station may need to wait
|
||
|
for human input and will allow for that
|
||
|
possibility in its determination of this
|
||
|
abnormally long period.
|
||
|
|
||
|
Once a management station has completed all
|
||
|
fields of an entry, it will set a value of
|
||
|
valid. This causes the entry to be
|
||
|
activated.
|
||
|
|
||
|
Entries in the valid state may also be set
|
||
|
to makeCall or clearCall to make or clear
|
||
|
X.25 calls to the peer. After such a set
|
||
|
request the entry will still be in the valid
|
||
|
state. Setting a value of makeCall causes
|
||
|
the agent to initiate an X.25 call request
|
||
|
to the peer specified by the entry. Setting
|
||
|
a value of clearCall causes the agent to
|
||
|
initiate clearing one X.25 call present to
|
||
|
the peer. Each set request will initiate
|
||
|
another call or clear request (up to the
|
||
|
maximum allowed); this means that management
|
||
|
stations that fail to get a response to a
|
||
|
set request should query to see if a call
|
||
|
was in fact placed or cleared before
|
||
|
retrying the request. Entries not in the
|
||
|
valid state can not be set to makeCall or
|
||
|
clearCall.
|
||
|
|
||
|
The values of makeCall and clearCall provide
|
||
|
for circuit control on devices which perform
|
||
|
Ethernet Bridging using static circuit
|
||
|
assignment without address recognition;
|
||
|
other devices which dynamically place calls
|
||
|
based on destination addresses may reject
|
||
|
such requests.
|
||
|

"This table contains the list of

encapsulations used to communicate with a

peer. This table has two indexes, the first
|

|
identifies the peer, the second
|
||
|
distinguishes encapsulation types.
|
||
|
|
||
|
The first index identifies the corresponding
|
||
|
entry in the mioxPeerTable. The second
|
||
|
index gives the priority of the different
|
||
|
encapsulations.
|
||
|
|
||
|
The encapsulation types are ordered in
|
||
|
priority order. For calling a peer, the
|
||
|
first entry (mioxPeerEncIndex of 1) is tried
|
||
|
first. If the call doesn't succeed because
|
||
|
the remote host clears the call due to
|
||
|
incompatible call user data, the next entry
|
||
|
in the list is tried. Each entry is tried
|
||
|
until the list is exhausted.
|
||
|
|
||
|
For answering a call, the encapsulation type
|
||
|
requested by the peer must be found the list
|
||
|
or the call will be refused. If there are
|
||
|
no entries in this table for a peer, all
|
||
|
call requests from the peer will be refused.
|
||
|
|
||
|
Objects in this table can only be set when
|
||

the mioxPeerStatus object with the same

|

that status object is set to invalid and
