CISCO-PREFERRED-PATH-MIB Table View

This table allows users to configure and monitor
the preferred path fcroute-map parameters on all
the VSANs configured on the local switch.
          
A fcroute-map can be created per VSAN. For each
fcroute-map users can create multiple routes which
are identified by a route ID. Within each route
there can be multiple flows which are configured
using the cPrefPathRouteMapMatchTable table and 
the corresponding outgoing interface for a route
can be configured using the 
cPrefPathRouteMapSetTable table.
          
This table is the top-level table which is used to
configure the fcroute-map indexed by VSAN ID
and a route within a fcroute-map indexed by the
route ID of the route.
          
Entries in this table are created and deleted
using the cPrefPathRouteMapRowStatus object.
          
To create a row in this table, a manager must
set the cPrefPathRouteMapRowStatus object
to 'createAndGo' or 'createAndWait'. This will 
create a route within a fcroute-map. There is
no need to configure instances of other 
corresponding columns -
cPrefPathRouteMapIntfPrefStrict, 
cPrefPathRouteMapRouteActive,
cPrefPathRouteMapActive in order to make the
newly created row to active.
          
To delete a row in this table, a manager must
set the cPrefPathRouteMapRowStatus object
to 'destroy'. This will delete a route within a
fcroute-map.

This table allows users to configure and monitor
the preferred path fcroute-map global parameters.
          
Entries in this table are automatically created
when the first route in a fcroute-map is created
using the cPrefPathRouteMapTable table.
          
An entry is deleted automatically from this table
if either:
- The last route in a fcroute-map is removed using 
  the cPrefPathRouteMapTable table.
       or
- The corresponding VSAN is deleted using the 
  vsanTable table (Defined in CISCO-VSAN-MIB).

This table allows to configure and monitor
the match criteria for a route within a 
fcroute-map created using the 
cPrefPathRouteMapTable table. 
          
Each match criteria allows user to classify a
traffic flow based on the the incoming frame's
source FC-ID and destination FC-ID match.
          
Each entry in this table is indexed by the 
 - cPrefPathRouteMapVsanIndex 
 - cPrefPathRouteMapRouteIndex 
 - cPrefPathRMapMatchSrcAddr 
 - cPrefPathRMapMatchSrcAddrMask 
 - cPrefPathRMapMatchSrcIntf 
 - cPrefPathRMapMatchDstAddr 
 - cPrefPathRMapMatchDstAddrMask 
          
Note that any changes or updates made to the match
criteria would require the corresponding route
or the corresponding fcroute-map to be activated
again.
          
Entries in this table are created and deleted
using the cPrefPathRMapMatchRowStatus object.
          
To create a row in this table, a manager must
set the cPrefPathRMapMatchRowStatus object
to 'createAndGo' or 'createAndWait'. This will 
create a match criteria for a route within a 
fcroute-map. 
          
To delete a row in this table, a manager must
set the cPrefPathRMapMatchRowStatus object
to 'destroy'. 
          
This table is dependent on cPrefPathRouteMapTable 
table. The association between this table and 
cPrefPathRouteMapTable table is through the common
indices - cPrefPathRouteMapRouteIndex and
cPrefPathRouteMapVsanIndex.
          
All the entries in this table with the indices - 
cPrefPathRouteMapVsanIndex and
cPrefPathRouteMapRouteIndex is in fact the match
criteria or the flows associated with the route
within a fcroute-map for a VSAN, which are created
and activated using the cPrefPathRouteMapTable table.
          
When the row corresponding to indices -
cPrefPathRouteMapVsanIndex and 
cPrefPathRouteMapRouteIndex in
the cPrefPathRouteMapTable is destroyed then all
the rows in this table with those indices will be
destroyed.

This table allows to configure and monitor
the set criteria for a route within a
fcroute-map created using the
cPrefPathRouteMapTable table. 
          
Each set criteria allows user to setup an action
on the classified or matched traffic flow created
using the cPrefPathRouteMapMatchTable table.
          
Each set criteria allows user to setup an outgoing
interface, and associate it with a preference level.
Preference level indicates the priority of the
interface during the selection in case multiple
outgoing interfaces are configured.
          
Match criteria configured using the
cPrefPathRouteMapMatchTable table for a route
within a fcroute-map and the set criteria
(this table) configured for the same route within
a fcroute-map go together as (match, set) pair.
Which means that those matched traffic
flows will be forwarded or routed via the interface
selected based on the preference level in the set
criteria (this table).
          
Each entry in this table is indexed by the 
 - cPrefPathRouteMapVsanIndex 
 - cPrefPathRouteMapRouteIndex 
 - cPrefPathRMapSetIntfPref         
          
Note any changes or updates made to the set
criteria would require the corresponding route
or the corresponding fcroute-map to be activated
again.
          
Entries in this table are created and deleted
using the cPrefPathRMapSetRowStatus object.
          
To create a row in this table, a manager must
set the cPrefPathRMapSetRowStatus object
to 'createAndGo' or 'createAndWait'. This will 
create a set criteria for a route within a
fcroute-map. It is required to configure instances
of cPrefPathRMapSetIntf column before or
concurrently in order to make the newly created
row to active. 
          
To delete a row in this table, a manager must
set the cPrefPathRMapSetRowStatus object
to 'destroy'. 
          
This table is dependent on cPrefPathRouteMapTable
table. The association between this table and the
cPrefPathRouteMapTable table is through the common
indices - cPrefPathRouteMapVsanIndex and
cPrefPathRouteMapVsanIndex. All the entries in this
table with the indices - cPrefPathRouteMapVsanIndex
and cPrefPathRouteMapRouteIndex is in fact the set
criteria associated with the route within a
fcroute-map, which are created and activated in the
cPrefPathRouteMapTable Table.
          
When the row corresponding to indices -
cPrefPathRouteMapVsanIndex and 
cPrefPathRouteMapRouteIndex in
the cPrefPathRouteMapTable is destroyed then all
the rows in this table with those indices will be
destroyed.

This table contains information of the 
'preferred path' that is currently active and 
selected for a route within a fcroute-map.
The 'preferred path' is the selected preference
level, and its associated interface which will be
the outgoing interface for traffic that are
classified using the match criteria in that
particular indexed fcroute-map route. 
          
Each entry in this table is indexed by 
 - cPrefPathRouteMapVsanIndex 
 - cPrefPathRouteMapRouteIndex 
          
For each route in a fcroute-map, preferred path
selects a preference level (the lower the number
the higher the preference) per VSAN based on link
status of interface associated with the
preference level. This table contains the
information of the selected preference level.

This table allows to monitor the status of the 
the match criteria of the route within a 
fcroute-map that are activated using the
cPrefPathRouteMapGlobalActive or
cPrefPathRouteMapRouteActive objects.
          
Each match criteria entry in this table is indexed
by 
 - cPrefPathRouteMapVsanIndex 
 - cPrefPathRouteMapRouteIndex 
 - cPrefPathRMapMatchSrcAddr 
 - cPrefPathRMapMatchSrcAddrMask 
 - cPrefPathRMapMatchSrcIntf  
 - cPrefPathRMapMatchDstAddr 
 - cPrefPathRMapMatchDstAddrMask

This table allows to monitor the status of the 
the set criteria of the route within a 
fcroute-map that are activated using the
cPrefPathRouteMapGlobalActive or
cPrefPathRouteMapRouteActive objects.
          
Each entry in this table is indexed by 
 - cPrefPathRouteMapVsanIndex 
 - cPrefPathRouteMapRouteIndex 
 - cPrefPathRMapSetIntfPref.
