Chapter 30: Unified Electronic Surveillance
STANDARD Revision 1.0 C4® CMTS Release 8.3 User Guide
© 2016 ARRIS Enterprises LLC. All Rights Reserved. 880
Note: For security reasons Legal Intercept should be configured for SNMPv3 access only.
Feature Operation
The operation of this feature includes the following highlights:
1. Feature activation is transparent to the subject.
2. The feature provides authentication, auditing, and logging mechanisms to prevent unauthorized creation or detection
of intercepts.
3. Supports 320 simultaneous Service Independent Intercept (SII) taps. (Note: A maximum of 127 subscribers can be set
up with LI Taps on each 12U CAM due to hardware limitations.)
4. Support for FlexPath Contributing Cable Modems (CCMs) by configuring the same tap session for each CM associated
with the bonded Flexpath CM group.
5. Support for co-existence of Legal Intercept and PacketCable Electronic Surveillance (Note: PacketCable Electronic
Surveillance takes precedence over LI in flows created by PacketCable 1.x).
6. Content delivery encapsulation format is compatible with PacketCable Electronic Surveillance.
7. Support for activation of tap sessions for CMs that are not currently registered at the CMTS.
8. Support for tap sessions that persist across CM reboots.
9. Support for data stream specification at Layer 2 (802 stream) only, as designated by a CM MAC address.
10. Support for tap sessions across all DSx activity.
11. The CMTS supports taps on IPv6-registered cable modems.
12. The output of the show running config command encrypts the identity of a subscriber intercepted by a config
cable intercept command and suppresses userid and password values that may have been used to execute the
command.
13. Only one LI tap session per subscriber is permitted. Any attempt to add a second tap or to change the parameters of
the existing tap are rejected. The existing tap must be deleted before it can be replaced or altered.
14. If an LI tap session is manually deleted or automatically removed when it reaches its expiration time as defined by the
until keyword, the CALEA tap on the same subscriber, if there is one, is not affected.
15. LI taps persist after a Control Complex fail-over in a duplex chassis.
