CISCO-ITP-GRT-MIB

This MIB is for managing information required to 
route messages transported over Signalling System 
No. 7 (SS7) Network via Cisco IP Transfer
Point.  
        
The Cisco IP Transfer Point (ITP) is a hardware 
and software solution that transports SS7 traffic 
using IP.  Each ITP node provides the functions
necessary to act as a SS7 signalling point.  Each 
signalling point is connected to other signalling 
point using IP based or traditional TDM links.
        
The relevant ITU documents describing this technology 
are the ITU Q series, including ITU Q.700: Introduction
to CCITT Signalling System No. 7 and ITU Q.701 
Functional description of the message transfer part
(MTP) of Signalling System No. 7.
        
        
Definitions and overview:
        
Route:
A route consists of one or more linksets used to transport
MTP3 Message Signal Units(MSU) between signalling points.  
A route is an association between a destination point 
code(DPC) and a linkset, i.e., a linkset that can be used
to send an MSU to the given DPC.
        
Routeset:
A routeset is a set of routes to a given DPC.  Each route
within a routeset is on a possible path toward the DPC.
Each route within the routeset has associated with it a
route priority.
        
In the following simple configuration, two routes exist
that can be used to transport MSUs from STP1 to STP4.
        
  ---------         STP1-STP2         --------- 
  - STP1  ----------------------------- STP2  - 
  ---------                           --------- 
      |                                   |
      | STP1-STP3               STP2-STP4 |
      |                                   |
  ---------         STP3-STP4         --------- 
  - STP3  ----------------------------- STP4  - 
  ---------                           --------- 
        
Routeset on STP1 for DPC = STP4:
    STP1-STP2,
    STP1-STP3
        
        
Linkset:
A linkset is a set of signalling links connecting
two signalling points.
        
Combined Linkset: 
Two linksets with equal number of links and capacity
that form routes of equal priority to a given DPC are
called Combined Linksets.  It is primarily used for
load sharing and redundancy.  In the following, example,
linksets 'SSP1-STP1' and 'SSP1-STP2' form a combined 
linsket.
          
           
        SSP1-STP1             ---------
     |------------------------- STP1  -
     |                        ---------
    - - 
  -     -
 -  SSP1 -  
  -     -
    - - 
     |  SSP1-STP2            ---------
     |------------------------ STP2  -
                             ---------
        
Routing:  
The routing of SS7 Message signalling Units(MSU) is based 
on the DPC.  Message Signalling Units are sent from an
originating point code(OPC) to DPC.  Each MSU will 
traverse one or more linksets as it is routed to its 
final destination.  When an MSU arrives at a signalling
point and the DPC does not match the signalling point's
point code the MSU must be directed toward the DPC.  Each
signalling point has enough routing information to 
determine which linkset should be used to transmit the
MSU toward its final destination.
        
Route statement:  
Each ITP Signalling Point has route statements needed to
determine which linkset should be used to transmit 
message signalling units to destinations.  Each route
statement consists of a destination, a priority and a
linkset name.  The destination is specified as a 
combination of DPC and mask.  The priority, also know
as cost, is used to define the order in which the routes
are selected.  The linkset name specifies which linkset
to use to reach the destination.
        
Route table:  
Each ITP Signalling Point has a table of routes.  
These route entries are used to determine which linkset
should be selected to transmit message signalling units 
to a given destination.  
        
There are two basic type of routing.  The first type
is fully-qualified and uses all bits of the target DPC.  
The other type is summary routing that uses a subset
of the bits in the target DPC and is used to represent 
groups of point codes rather than a single point code.
        
Example of route table entries.
        
Example 1: variant = ITU
        
DPC/MASK  Priority  Linkset-name
--------  --------  -----------------------
5.5.5/14  3         STP1-STP2
5.5.5/14  7         STP1-STP3
        
Description: Two route table entries that define a
primary route using linkset 'STP1-STP2' and an alternate
route using linkset 'STP1-STP3' to point-code 5.5.5.
        
Example 2: variant = ITU
        
DPC/MASK  Priority  Linkset-name
--------  --------  -----------------------
5.5.5/14  3         STP1-STP2
5.5.5/14  3         STP1-STP3
5.5.5/14  7         STP1-STP4
        
Description: Two route table entries that define a
combined linkset consisting of linkset 'STP1-STP2' and
'STP1-STP3' to point code 5.5.5.  An alternate route is
also defined using linkset 'STP1-STP4'.
        
Example 3: variant = ANSI
        
DPC/MASK  Priority  Linkset-name
--------  --------  -----------------------
5.5.0/16  3         STP1-STP2
        
Description: A route table entry that defines routing
to a cluster.  The cluster represents all point codes
in the range from 5.5.0-5.5.255.
        
Example 4: variant = ANSI
        
DPC/MASK  Priority  Linkset-name
--------  --------  -----------------------
5.5.0/16  3         STP1-STP3
5.5.5/24  3         STP1-STP2
        
        
Description: The mixing of fully-qualified and summary
route table entries allow for different routes to be
defined for certain DPC in a cluster.  In this 
configuration, the fully-qualified route will be the 
primary and the summary route will act as a backup.

Notifications/Traps

NameOIDDescription
ciscoGrtDestStateChange




.1.3.6.1.4.1.9.9.334.0.1
ication is generated whenever one or more
destination changes states. This notification 
contains a list of destination state changes in the
cgrtDestNotifChanges object.  State changes are
accumulated until the cgrtDestNotifChanges is 
full or the maximum delay time is reached.  The delay
time is specified by the cgrtDestNotifDelayTime 
object.
          
It may be necessary to suppress the sending of 
notification when a large number destinations change 
state, due the failure of some common resource.  The 
number of notifications can be controlled by 
specifying values for cgrtDestNotifWindowTime 
and cgrtDestNotifMaxPerWindow objects.  When the 
number of destination state changes exceed the 
specified value the last notification will indicate 
that notifications are suppressed for the remainder
of the window.
          
This notification is deprecated by 
ciscoGrtDestStateChangeRev1.
ciscoGrtMgmtStateChange




.1.3.6.1.4.1.9.9.334.0.2
ication is generated whenever one or more

contains a list of management route state changes 
in the cgrtMgmtNotifChanges object.  State changes 
are accumulated until the cgrtMgmtNotifChanges
is full or the maximum delay time is reached.  The 
delay time is specified by the 
cgrtMgmtNotifDelayTime object.
          
It may be necessary to suppress the sending of

ciscoGrtNoRouteMSUDiscards





.1.3.6.1.4.1.9.9.334.0.6
ication is generated whenever one or more
MSU discards happen due to route data error for a
specific signalling point instance in the configured
cgrtNoRouteMSUsNotifWindowTime.  For cases when there
is a non-zero number of MSUs discarded, this
notification will be sent at the end of the
cgrtNoRouteMSUsNotifWindowTime interval, with
cgrtIntervalNoRouteMSUs indicating the total count of
MSUs discarded for that specific signalling point
instance during the entire cgrtNoRouteMSUsNotifWindowTime
interval Q752/5.5.
