Chapter1 Overview of CiscouBR10012 Universal Broadband Router Software Supported Software Features for the CiscouBR10012 Router
This feature allows service providers to create a Layer 2 tunnel by mapping an upstream service
identifier (SID) to an IEEE 802.1Q Virtual Local Area Network (VLAN).
For additional information about configuring TLS on the Cisco uBR10012 CMTS, refer to the following

http://www.cisco.com/univercd/cc/td/doc/product/cable/cab_rout/cfig_nts/tls-cmts.htm
Cisco TLS for the Cisco uBR10012 router requires the PRE2 performance routing engine module with
Cisco IOS Release 12.3(9a)BC or a later release in the Cisco IOS 12.3BC train.
Transparent LAN Service and Layer 2 Virtual Private Networks
Cisco IOS Release 12.3(13a)BC introduces the following changes or requirements for the TLS feature with
Layer 2 VPNs:
When the TLS feature is used with Layer 2 VPNs, the participating cable modems must have the
Baseline Privacy Interface security feature (BPI) enabled. Otherwise, the Cisco CMTS drops such
Layer 2 traffic in the upstream or downstream.
Information about Customer Premises Equipment (CPE) does not display in the output of the
showcable modem command.
