Description: The x25LinkEntry is created automatically, when a link becomes active. The entry is also removed automatically, if a link becomes disconnected. It may be removed manually by setting the field x25LinkState to delete, which causes the related link to be disconnected.

IfIndex
The index of the interface the link is running on.
See ifTable.
Addr
On point-to-multipoint interfaces, this field contains the
(MAC-)address of the partner, the link is leading to.
It is empty for point-to-point interfaces, because there
is only one partner at the other side.
Mode
This field indicates wheter the Layer 3 on top of the link
is operated in DTE or DCE mode. The difference is in the
order of VC-assignment, the handling of a call collision
and the range of allowed values of the cause field.
Enumerations:
  • dte (1)
  • dce (2)
Modulo
This field indicates whether the layer 3 on top of the link
is in modulo 8 or in modulo 128 mode.
Enumerations:
  • mod8 (1)
  • mod128 (2)
LIC
Lowest Incoming Channel as seen from the DTE. The value
-1 means no incoming channels.
HIC
Highest Incoming Channel as seen from the DTE. The value
-1 means no incoming channels.
LTC
Lowest Twoway Channel as seen from the DTE. The value
-1 means no twoway channels.
HTC
Highest Twoway Channel as seen from the DTE. The value
-1 means no twoway channels.
LOC
Lowest Outgoing Channel as seen from the DTE. The value
-1 means no outgoing channels.
HOC
Highest Outgoing Channel as seen from the DTE. The value
-1 means no outgoing channels.
DefPktSize
The default 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 is always 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.
State
This object contains the current state of the link. The
link may be manually disconnected by setting this object
to the value delete.
Enumerations:
  • restart-pending (1)
  • restart-collision (2)
  • ready (3)
  • disc-pending (4)
  • reset-pending (5)
  • sabm-pending (6)
  • xid-pending (7)
  • sabm-wait (8)
  • l1connect-pending (9)
  • l1-ready (10)
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.
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.
L1IdleTimer
The idle timer in milliseconds for the layer 1 of this
link. If layer 2 is disconnected and the time specified 
by this object expired, the layer 1 will be disconnected. 
The value 0 means, the layer 1 should not be disconnected 
after the layer 2 is disconnected.
A value of -1 means, that the layer 1 shall be kept up
even if it get disconnected from the partner on the
other end.
ActSabmDelayTimer
The sabm delay timer in milliseconds for this link (only 
dialup outgoing link). This timer specifies the time interval 
between establishment of layer 1 and sending of SABM packet.
If layer 1 is established and the time specified by this 
object expired, SABM packet will be sent. The value 0
means, SABM packet should be sent immediately after 
establishment of layer 1. The value -1 means, SABM packet
should not be sent by dialup outgoing link.
PsvSabmDelayTimer
The passive sabm delay timer in milliseconds for this 
link (only dialup incoming link). This timer specifies the time
interval between establishment of layer 1 and sending of SABM 
packet. If layer 1 is established and the time specified by 
this object expired, SABM packet will be sent. The value 0 
means, SABM packet should be sent immediately after 
establishment of layer 1. The value -1 means, SABM packet 
should not be sent by dialup incoming link.
