Basic Wiretap Support
This operations feature provides a mechanism that enables capture of user-to-user traffic. The wiretap
facility is based on the MAC address of the RF CPE device, so the wiretap facility can be used for either
data or digitized higher-priority connections. The feature is controlled by the new interface command,
cable intercept, which requires a MAC address, an IP address, and a Universal Data Protocol (UDP)
port number as its parameters:
cable intercept [mac-address] ip-address udp-port
When activated, the CiscouBR10012router examines each packet for the desired MAC address. When
a matching MAC address is found (for either the origination or destination endpoint), a copy of the
packet is encapsulated into a UDP packet, which is then sent to the specified server at the given
IPaddress and port.
For additional command information, refer to the CiscoBroadband Cable Command Reference Guide
on Cisco.com.
Cable Monitor Enhancements
Cisco IOS Release 12.3(17a)BC introduces the following enhancements to the cable monitor feature:
•Access Control Lists are now supported on the Cisco uBR-MC5X20U/D and Cisco uBR-MC28U
cable interface line cards
•Unconditional downstream sniffing now enables downstream packets to be monitored, either for
MAC or data packets. This enhancement supports both DOCSIS and Ethernet packet encapsulation.
