The SBC Core supports the use of the Master Trunkgroup Resource Manager (MTRM) to manage call and bandwidth resources on clients spread across multiple SBCs, thus enabling service providers to support enterprise customers using enterprise-wide CAC management down to the location and trunk group levels.The Master Trunkgroup Resource Manager (MTRM) is basically a client/server model consisting of a Master Trunk Group Server (MTRG server) and Master Trunk Group Client (MTRG client). The server and client are associated with a common name. MTRG-server and MTRG-client instances can co-exist in the same SBC, or can reside in different SBCs.
The MTRG-server is configured with a CAC pool shared amongst its registered MTRG-clients. This CAC pool consists of call and bandwidth resources.
The MTRG client registers with the respective MTRG server and requests for a configurable margin of call and/or bandwidth resources. The CAC resources configured on the server are shared and dynamically redistributed between the registered clients. Each client can optionally maintain its own set of local resources and/or obtain aggregate resources from the respective server. As idle client resources fall below a configurable margin (calls/bandwidth per request), a client requests more resources from the server. The server, depending on the availability, may or may not grant the resources.
If the connection between the Mtrm server and client fails, IPTG will fall back to its local resources.
For the MTRG feature to work as per expectation, the egress and ingress callLimit of the IPTG must be set to unlimited (default value).
For Mtrm to work as designed, the parent cac pool should not be configured for a TG.
The reset
command has no impact if executed on a disabled or out-of-service object.

Mtrm Conn Port - Client parameters
Parameter | Description |
---|
Index | Specifies the index of this Master Trunk Group Connection Port. The value ranges from 1 to 128 characters.
|
Mode | Specifies the operational mode for this Mtrm connection port. The options are: outOfService inService (default)
|
State | Specifies the administrative state of the Mtrm connection port. The options are: disabled (default) enabled
|
Port Role | Specifies the role of the Mtrm connection port. By default none of the options are selected. The options are: |
Primary Server IPAddr | Specifies the IP address of the primary server. This can be IPv4 or IPv6 address. |
Primary Server Port Number | If the portRole is a server, this is the Mtrm listen Port, If the portRole is a client, this is the Mtrm server port to connect to. The value ranges from 4000 to 4500 and the default value is 4360. |
Ip Interface Group Name | Specifies the IP Interface Group name used by this Mtrm Connection Port. |
Mgmt Interface Group Name | Specifies the MGMT interface group name used by this Mtrm connection port. |
Ip Address V4 | If the portRole is a server, this is the IPV4 listen address of the Mtrm Connection Port. If the portRole is a client, this specifies the local IPV4 address. |
Ip Address V6 | If the portRole is a server, this is the IPV6 listen address of the Mtrm Connection Port. If the portRole is a client, this specifies the local IPV6 address. |
Secondary Ip Address | Specifies the IP address of the secondary server. This can be IPv4 or IPv6 address. |
Secondary Port Number | Specifies the port number of the Mtrm secondary server. |
Health Check Interval | Specifies the Mtrm HealthCheck interval in seconds. A health check message will be sent to peer at this interval. The value ranges from 1 to 50 and the default value is 5. |
Health Check Timeout | Specifies the health check time out in seconds, client connection will timeout if no response is received from client and client connection will time out if no healthcheck message is received from server for this much span of time. The value ranges from 1 to 120 and the default value is 25. |
Health Check Ignore | Specifies whether to ignore the health time out or not. If this parameter is enabled, health time out is ignored. The options are: disabled (default) enabled
|
Retry Count | Specifies the number of times the connection attempt will be made to the peer. The connection will switch to alternate server after number of retrycount expires. The value ranges from 3 to 20 and the default value is 5. |
Server Reconnect Interval | Specifies the amount of time in seconds after which the client tries to connect to the server. The value ranges from 1 to 150 and the default value is 5. |
Force Secondary Connection | This parameter forces the Mtrm Connection Port to its secondary for a geo-redundant client.
enabled : If connected to primary, Mtrm connection port will be forced to secondary. If connected to secondary, Mtrm connection port will remain connected to secondary even if the primary is available. disabled : The primary server affinity will be restored. The options are: disabled (default) enabled
