ACCIONES CORRECTIVAS POR DESEMPEÑO DEL PROCESO

1. In Superuser mode, type configure terminal and press Enter.

ACMEPACKET# configure terminal

2. Type session-router and press Enter.

ACMEPACKET(configure)# session-router

3. Type account-config and press Enter.

ACMEPACKET(session-router)# account-config

ACMEPACKET(account-config)#

4. hostname—Enter a hostname for this system.

5. port—Enter 3868 for the RFC-recommended Diameter port number. You may enter a different port number. • minimum: 1025

• maximum: 65535

6. strategy—Set the strategy used to select the accounting server which the SBC sends accounting messages. The following table lists the available strategies:

Value Description

hunt Selects accounting servers in the order in which they are listed. ®

Value Description

If the first accounting server is online, working, and has not exceeded any of the defined constraints, all traffic is sent to it. Otherwise the second accounting server is selected. If the first and second accounting servers are offline or exceed any defined constraints, the third

accounting server is selected. And so on through the entire list of configured servers

failover Uses the first server in the list of predefined accounting servers until a failure is received from that server. Once a failure is received, it moves to the second accounting server in the list until a failure is received. And so on through the entire list of configured servers.

round robin Selects each accounting server in order, distributing the selection of each accounting server evenly over time.

fastest round trip time Selects the accounting server that has the fastest round trip time (RTT) observed during transactions with the servers (sending a record and receiving an ACK).

fewest pending Selects the accounting server that has the fewest number of

unacknowledged accounting messages (that are in transit to the SBC).

7. protocol—Set this parameter to diameter to use the Rf accounting interface with a Diameter-based accounting server.

8. state—Enter enabled to use accounting on this system.

9. max-msg-delay—Retain the default value of 60 seconds or indicate the length of time in seconds that you want the SBC to continue trying to send each accounting message. During this delay, the SBC can hold a generic queue of 4096 messages.

• Minimum: zero (0) • Maximum: 4294967295

10.max-wait-failover—Retain the default value of 100 messages or indicate the maximum number of accounting messages the SBC can store its message waiting queue for a specific accounting server, before it is considered a failover situation.

Once this value is exceeded, the SBC attempts to send it accounting messages, including its pending messages, to the next accounting server in its configured list.

• Minimum: one (1) message • Maximum: 4096 messages

11.trans-at-close—Retain the default value of disabled if you do not want to defer the transmission of message information to the close of a session. Enter enabled if you want to defer message transmission. • disabled—The SBC transmits accounting information at the start of a session (Start), during the session

(Interim), and at the close of a session (Stop). The transmitted accounting information for a single session might span a period of hours and be spread out among different storage files.

• enabled—Limits the number of files on the SBC used to store the accounting message information for one session. It is easiest to store the accounting information from a single session in a single storage file.

12.generate-start—Retain the default value ok if you want the ACR Start message to be generated once the SBC receives an OK message in response to an INVITE.

Other options include:

• none—Accounting Start message should not be generated.

• invite—Accounting Start message should be generated once the SBC receives a SIP INVITE.

13.generate-interim—Retain the default value reinvite-response to cause the SBC to send an Interim charging message to the accounting server.

You can select none, one, or more than one of the following values:

Value Description

ok Start message is generated when the SBC receives an OK message in response to an INVITE.

reinvite Interim message is generated when the SBC receives a SIP session reINVITE message.

reinvite-response (default) Interim message is generated when the SBC receives a SIP session reINVITE and responds to it (for example, session connection or failure).

reinvite-cancel Interim message is generated when the SBC receives a SIP session reINVITE, and the Reinvite is cancelled before the SBC responds to it. unsuccessful-attempt Interim message is generated when a SIP session set-up attempt from a

preference-ordered list of next-hop destinations is unsuccessful. This can happen when a local policy lookup, LRT lookup, ENUM query response, or SIP redirect returns a preference-ordered list of next-hop destinations. The interim message contains: the destination IP address, the disconnect reason, a timestamp for the failure, and the number that was called.

14.intermediate-period—Enter amount of time in seconds between generating periodic interim ACR

messages during a SIP call. This parameter defaults to zero, which disables continuous Interim charging messages.

15.vsa-id-range—Ensure that this parameter is left blank when communicating with a Diameter-based Rf accounting server.

16.generate-event—Enter one or more valid events that prompt creation of an Event record. Current valid values are register and local-register. Multiple values are entered enclosed in parenthesis and separated by spaces.
