MAG Service Configuration Mode Commands

MAG Service Configuration Mode Commands
 
Products using commands in this mode: HSGW, S-GW
The MAG Service Configuration Mode is used to create and manage a Mobility Access Gateway service in an HSGW (eHRPD network) or a P-MIP S-GW (LTE-SAE network). The MAG is the PMIP client and communicates with the Local Mobility Anchor (LMA) configured on a PDN Gateway (P-GW).
bind address
Binds the service to a logical IP interface serving as the S2a (HSGW) or S5/S8 (S-GW) interface and specifies the maximum number of subscribers that can access this service over the configured interface.
Product
HSGW, S-GW
Privilege
Administrator
Syntax
bind address ip_address [ max-subscribers num ]
no bind address
no
Removes the interface binding from this service.
ip_address
Specifies the IPv6 address of the interface configured as the S5/S8 interface. ip_address is specified in IPv6 colon-separated notation.
max-subscribers num
Default: 1500000
Specifies the maximum number of subscribers that can access this service on this interface. num must be an integer from 0 through 3000000.
note_smallImportant: The maximum number of subscribers supported depends on the installed license key and the number of active packet processing cards in the system. A fully loaded system can support 3,000,000 total subscribers. Refer to the license key command and the Usage section (below) for additional information.
Usage
Associate the MAG service to a specific logical IP address. The logical IP address or interface takes on the characteristics of an S2a or S5/S8 interface that provides the session connectivity to/from a P-GW. Only one interface can be bound to a service. The interface should be configured prior to issuing this command.
This command also sets a limit as to the number of simultaneous subscribers sessions that can be facilitated by the service/interface at any given time.
When configuring the max-subscribers option, be sure to consider the following:
•
The total number of S2a or S5/S8 interfaces you will configure
•
The total number of subscriber sessions that all of the configured interfaces may handle during peak busy hours
•
An average bandwidth per session multiplied by the total number of sessions
•
The type of physical port to which these interfaces will be bound
Taking these factors into account and distributing your subscriber session across all available interfaces will allow you to configure your interfaces to optimally handle sessions without degraded performance.
Example
The following command would bind the logical IP interface with the address of 4551:0db8:85a3:08d3:3319:8a2e:0370:1344 to the MAG service and specifies that a maximum of 300,000 simultaneous subscriber sessions can be facilitated by the interface/service at any given time:
bind address 4551:0db8:85a3:08d3:3319:8a2e:0370:1344 max-subscribers 300000
