|
| This textual convention is used to indicate association between
profile or gateway and MGC group.
The value, greater than zero which is used to identify index of
MGC group (same as CMgcGroupIndex) which is associated with
profile or gateway. The mapping between MGC group and profile
or gateway is 1 to N.
The value, equal to zero which means there is no association
between profile or gateway and MGC group. |

1.3.6.1.4.1.9.9.321 |
| This MIB is used to support MGC(call agent) and
MGC Group configuration.
The MGC or MGC group configuration is performed
under a specific gateway(cmgwIndex).
The call agent is an external element (outside
of gateway) with call control intelligence
to control call connection in gateway.
The protocols used for communication between voice
gateway and call agent included SGCP, MGCP, ...
Multiple IP addresses can be associated with one
call agent.
An MGC group is a logical grouping of several MGCs
into one group.
MGC redundancy is used to support multi call agent
for one gateway. With MGC redundancy, a voice
gateway can send gateway-initiated-commands to the
next MGC in the MGC group if it fails to receive
response from any IP address(es) associated to the
current MGC.
To use MGC redundancy in gateway:
Step 1: add individual entry (in any order) for
profile
MGC
Step 2: make association between the entries
1 IP with MGC
2 MGC with MGC group
1/2 protocol with MGC group
3 MGC group with profile
or
MGC group with gateway
Only if a MGC group at least is associated with
one profile or gateway, then the MGC group can be
used, otherwise the MGC group is useless.
To delete the following entries, it is needed to
do de-association first:
profile
MGC
When do de-association, the order is opposite to that
of association.

Each entry in this table should have a unique domain name
representing a call agent.
Adding/deleting entry in this table is controlled by
'cMediaGwDomainNameConfigTable' of CISCO-MEDIA-GATEWAY-MIB:
1. Entry creation
An entry in this table is created when its associated entry
in the 'cMediaGwDomainNameConfigTable' is created with the
value of 'mgc(3)' in the cmgwConfigDomainNameEntity object.
The 'cmgwConfigDomainName' of the associated entry in the
'cMediaGwDomainNameConfigTable' will be taken as
'cMgcDomainName' of the new entry.
2. Entry deletion
An entry of this table is deleted when its associated entry
in 'cMediaGwDomainNameConfigTable' is deleted.

| cMgcResolution |
1.3.6.1.4.1.9.9.321.1.1.1.1.5 |
| This object determines the kind of resolution to
be applied for this MGC.
'internalOnly' means that the gateway will not try to
resolve the IP address for this domain name using
external DNS name server.
'externalOnly' means the IP address for this domain name
will be resolved externally using DNS name server.
The request to change from 'internalOnly' to 'externalOnly'
will be rejected if the DNS name server is not available
for gateway.
The IP addresses related to the same MGC should have the
same cMgcResolution. The value of the MGC associated objects
in the cMgcIpConfigTable can not be modified by NMS if the
value of cMgcResolution for the MGC is 'externalOnly'.
The following are the behavior of changing the value of this
object.
[1] changing the value from 'externalOnly' to 'internalOnly'
1) precondition
MGC is not associated with any MGC group
(value of cMgcNumMgcGroups is zero).
2) behavior
If the value of this object is changed successfully,
all existing IP addresses in cMgcIpConfigTable that are
associated to the MGC will be removed automatically.
Note that MGW can't communicate with MGC if NMS does not
add static IP address into cMgcIpConfigTable for the MGC.
[2] changing the value from 'internalOnly' to 'externalOnly'
1) precondition
All MGC associated statically configured IP addresses
must be removed from cMgcIpConfigTable by NMS before
setting 'externalOnly' value to this object.
An inconsistentValue error is generated for setting
'externalOnly' value if the MGC associated IP addresses
are not removed.
2) behavior
After successfully setting 'externalOnly' value to this
object, the MGC domain name will be resolved by MGW
software using external DNS name server and the resulting
IP addresses will be added to cMgcIpConfigTable
automatically.

all IP addresses are equivalent.
all IP addresses will share the same domain name:

In order to delete an entry, following conditions need to be
met:
1. The MGC to which this IP address is being added,
should be existing.
2. The MGC's resolution (cMgcResolution) should be
'internal only'.
3. the mandatory object is cMgcIpAddress
After the IP address added to the MGC
the related 'cMgcNumIP' in MGC table will be incremented
by 1.
In order to delete an entry, following conditions need to be
met:
1. The MGC's resolution (cMgcResolution) should be
'internal only'.
2. The IP address should not be the only one in the MGC
while the MGC is associated with MGC group.
This means if the value of 'cMgcNumIP' is equal to 1
and the value of 'cMgcNumMgcGroups' is non-zero,
this IP address is the only one associated with the MGC
and it is possible that this IP address is also the
only one associated with MGC group. Therefore this
IP address can not be deleted.
After deleting the IP address from the MGC the related
'cMgcNumIP' in MGC table will be decremented by 1.

When gateway does not know which protocol is used by a call
agent the preference is used to make the decision.
But if gateway knows which protocol used by a call agent,
gateway will use that protocol (as long as the protocol is
added to the MGC group, irrespective of the preference) to
communicate with the call agent.
For example:
when gateway return a call agent message, gateway
will use the protocol which used by the call agent to
send the message.
