>> Table: x25LinkPresetTable - (.1.3.6.1.4.1.272.4.6.2.1)

Description: Entries in this table are created by defining a new value for the field x25LkPrIfIndex. Entries may be deleted by setting the field x25LkPrMode to the value delete. Please note, that changing the entries dont have influence on links being already established. To take effekt the according links have to be cleared either manually (see x25LinkTable) or by other means.

IfIndex
The interface index of the link to be predefined. This
object identifies a row in the ifTable.
Addr
On point-to-point links, this field must be empty. On
point-to-multipoint links, this field may be empty or
set to a partners (MAC-) address. In the first case, the
definition is valid for all links on the interface
except for those having a specific predefiniton.
In the second case the definition defines the link parameters
for a specific partner.
Mode
This field indicates, whether the link is initially operated
in DTE or DCE mode. If a misconfiguration is detected,
(DTE<->DTE od DCE<->DCE) the DTE/DCE assignement is done
be means of the procedure defined in ISOxxxx.
Enumerations:
  • dte (1)
  • dce (2)
  • delete (3)
Modulo
This object indicates, whether the link should be operated
in modulo 8 or modulo 128 mode.
Enumerations:
  • mod8 (1)
  • mod128 (2)
LIC
Lowest Incoming Channel as seen from the DTE. Depending
on the value of x25LkPrVC0, the value of -1 or Zero means
no incoming channels.
HIC
Highest Incoming Channel as seen from the DTE. Depending
on the value of x25LkPrVC0, the value of -1 or Zero means
no incoming channels.
LTC
Lowest Twoway Channel as seen from the DTE. Depending
on the value of x25LkPrVC0, the value of -1 or Zero means
no twoway channels.
HTC
Highest Twoway Channel as seen from the DTE. Depending
on the value of x25LkPrVC0, the value of -1 or Zero means
no twoway channels.
LOC
Lowest Outgoing Channel as seen from the DTE. Depending
on the value of x25LkPrVC0, the value of -1 or Zero means
no outgoing channels.
HOC
Highest Outgoing Channel as seen from the DTE. Depending
on the value of x25LkPrVC0, the value of -1 or Zero means
no outgoing channels.
DefPktSize
The Layer 3 packet size for this link.
Enumerations:
  • p128 (7)
  • p256 (8)
  • p512 (9)
  • p1024 (10)
  • p2048 (11)
  • p4096 (12)
DefWinSize
The default window size. This must be less than 8, if the
layer 3 is operated in modulo 8 mode.
MaxPktSize
The maximum allowable packet size for this link during
X.25 packet size negotiation. If this field is set to
unrestricted, the packet size will only be limited by
the Mtu size of the interface, which is always the
upper bound for the packet size.
Enumerations:
  • unrestricted (1)
  • p128 (7)
  • p256 (8)
  • p512 (9)
  • p1024 (10)
  • p2048 (11)
  • p4096 (12)
MaxWinSize
The maximum allowable window size for this link during
window size negotiation.
L2WinSize
The layer 2 window size for this link.
L2RetrTimer
The retransmission timeout in milliseconds for the
layer 2 of this link. If a frame is not acknowledged within
this timeout, it will be retransmitted.
L2RetrCounter
The retransmission counter for the layer 2 of this link.
If a frame has been retransmitted more often than indicated
by this object, the link will be reset or disconnected.
L2SupervTimer
The link-supervision timeout in milliseconds for the
layer 2 of this link. This timer is started, when the
link gets idle. An RR poll-sequence will be initiated,
when this timeout expires.
L2IdleTimer
The idle timer in milliseconds for the layer 2 of this
link. If no VCs are established and the the link has been
idle for the time specified by this object, the link
will be disconnected. The value 0 means, the link should
not be disconnected after the last VC has been cleared.
A value of -1 means, that the link shall be kept up
even if it get disconnected from the partner on the
other end.
Negotiation
This object determines whether packet-size and windows-size
parameters are negotiated for outgoing calls.  When set to
never, outgoing calls are cleared if the call parameters
differ from the default-settings. When set to when-necessary,
negotiation is only performed if the call parameters differ
from the default settings. When set to always, negotiation
is always performed.
Enumerations:
  • when-necessary (1)
  • always (2)
  • never (3)
DiscDelayTimer
The disc delay timer in milliseconds for the layer 2 of
this link (only outgoing links). This timer specifies the
time interval between receiving of layer 2 disconnect and
actual disconnect of link. If the partner want to
disconnect the layer 2 and the time specified by this object
expired, the link will be disconnected. The value 0 means, 
the link will be disconnected immediately after receiving of
disconnect.
CallDelayTimer
The call delay timer in milliseconds for the layer 3 of
this link (only outgoing link). This timer specifies the 
time interval between restart procedure completion and
virtual call setup. If restart procedure is completed 
and the time specified by this object expired, call packet 
will be sent. The value 0 means, call packet should be sent 
immediately after completion of restart procedure.
RestDelayTimer
The Restart delay timer in milliseconds for this link.
This timer specifies the time interval between 
establishment of layer 2 and sending of restart packet. 
If layer 2 is established and the time specified by this 
object expired, restart packet will be sent. 
The value 0 means, restart packet should be sent immediately 
after establishment of layer 2.
VC0
This object indicates, whether VC#0 shall be allowed on
the link. If this object is set to enable, VC#0 is allowed
and the value -1 shall be used to indicate the absence of
specified channels. This invalidates old configurations,
for which a value of 0 specifies the absense of a specified
channel. However, for compatibility reasons, if this object
is not set to enabled, the values -1 or 0 may be used to
specify the absence of a channel.
Enumerations:
  • enable (1)
  • disable (2)
RewritingRule
This Object specifies a rewriting rule in the X25 Rewrite
table. The call packet will be processed according
to this rewriting rule before the call is being routed.
If this value is set to zero, no rewriting will take
place.
