2   Changes to Default System Behavior in Release 6.5.1

2.1   Changes to Default System Behavior in Release 6.5.1.1

This release introduced the following changes to default system behavior.

2.1.1   Changes to Application Traffic Management

Application Traffic Management changed in Release 6.5.1.1 in the following ways.

2.1.1.1   dpi traffic-management statistics Command No Longer Enables Statistics Reporting

Previously, you enabled statistics reporting by entering the dpi traffic-management statistics command in global configuration mode. In this release, the dpi traffic-management statistics command configures only the frequency that accounting messages are sent to a forwarding server. To enable statistics reporting, enter the accounting command in Deep Packet Inspection (DPI) traffic-management policy configuration mode. Depending on whether the policy you are configuring is associated with a subscriber or subscriber group, when you enter the accounting command, you enable the corresponding level of statistics reporting.

For more information, see Application Traffic Management Configuration and Operation and Application Traffic Management Command Reference.

2.1.1.2   Per Subscriber Statistics Collection is Disabled by Default

Previously, you enabled statistics collection when you enabled statistics reporting. In this release, per subscriber statistics collection is disabled by default and is now enabled when you enter the statistics command in DPI traffic-management policy configuration mode.

For more information, see Application Traffic Management Configuration and Operation and Application Traffic Management Command Reference.

2.1.1.3   Syntax Changes for Application Traffic Management Commands

The card keyword replaces the asp keyword in the syntax for the following commands this release:

2.1.2   Subscriber Functionality Removed from Port Pseudowires

In the 6.5.1 release, the following commands (in port pseudowire configuration mode) used to configure subscriber-related port pseudowires have been removed:

In the port pseudowire command, the ethernet keyword has been removed.

This release does not support Point-to-Point Protocol over Ethernet (PPPoE) over port pseudowires (PWs).

For information about the new port PW feature in this release, see Technical Product Description.

2.1.3   BGP Next Hop Delay Time and Hold Time Enhancements

The implementation of the nexthop triggered holdtime has changed:

2.1.4   MID Format

In the previous release, the H.248 Message ID (MID) format for European Telecommunication Standards Institute (ETSI) Border Gateway Function (BGF) and Ericsson BGF profiles was {IP address]:Port and MGC group name/instance id@IP address respectively. In this release, the H.248 MID for both profiles is identical: MGC-group name/MGD instance id@system MAC.

2.1.5   MGC-group Name

In the previous release, the character set of the media gateway controller (MGC) group name was unrestricted. In this release, the valid value for the MGC group name is an alphanumeric string of up to 30 characters. The first character must be a letter.

2.1.6   Realm Name

The character set of the realm name did not conform to a fully qualified domain name (FQDN) format in the previous release. It now conforms in this release. The valid value of a realm name is a string of up to 63 characters and is case insensitive. The string must start and end with an alphanumeric character; can contain only letters, digits, hyphens (-), and periods (.); and must consist of at least two characters.

2.1.7   Timestamps for Core Dump Files

In previous releases, core dump files were not timestamped. Since "last modified" date of the file updates after a switchover, it was challenging to determine the time of the crash that created the core dump file. In this release, core dump files in the /md folder include a timestamp as part of the file name.

2.1.8   Changes to the access-group and access-list Commands

In this release, to support IPv6 and IPv4 ACLs and forwarding:

Although the router still accepts the access-list and access-group commandss, they do not appear in the online help and display as ip access-group and ip access-list in the show configuration. command output.
