There are no new hardware features in this release.

New Software Features in Release 15.4(2)S

Point-to-point protocol over Ethernet Intermediate Agent

Point-to-point protocol over Ethernet Intermediate Agent (PPPoE IA) is placed between a subscriber and Broadband Remote Access Server (BRAS).

PPPoE IA helps the service provider BRAS to distinguish between end hosts connected over Ethernet and an access device.

For more information about Point-to-point protocol over Ethernet Intermediate Agent, see the Cisco ME 2600X Series Ethernet Access Switch Software Configuration Guide, Release 15.4(2)S.

Multicast VLAN Registration Global

Multicast VLAN Registration (MVR) is now available in the global mode.

For more information about Multicast VLAN Registration, see the Cisco ME 2600X Series Ethernet Access Switch Software Configuration Guide, Release 15.4(2)S.

Determining the Software Version

To determine the version of Cisco IOS software that is running on your Cisco router, log in to the router and enter the show version EXEC command:
