An example using a group named LI-TAP-ADMINS:
configure snmp-server group LI-TAP-ADMINS v3 noauth read LI-TAP-VIEW write LI-TAP-VIEW notify
LI-TAP-VIEW
3. To add a user to a group:
configure snmp-server user <user_name> <group_name> v3 auth md5 <password>
Note: No spaces are allowed in the user name.
An example using user name JohnDoe and password TopSecret:
configure snmp-server user JohnDoe LI-TAP-ADMINS v3 auth md5 TopSecret
4. Use the following command to set the source interface for the SNMPv3 messages and the UDP/IP encapsulated
intercept traffic. If you do not use this command to set the source interface for LI, then the C4/c CMTS uses the same
source interface value that is used for SNMP traps.
configure snmp-server source-interface loopback <num> | cable-mac <mac> | ethernet <slot>/<port>
| loopback <int>
For example:
configure snmp-server source-interface loopback 0
5. To define which SNMP traps should be sent:
configure snmp-server notify-filter profile LI-TAP-NOTIFY subtree cTapMIBNotifications type
included
6. To configure the intercept source interface, enter:
configure cable intercept source-interface cable-mac <mac>[.<subif>]|loopback <int>
The source interface can be configured on an ethernet or loopback interface as well.
An example of configuring the intercept source interface on a cable-mac:
configure cable intercept source-interface cable-mac 25
7. The CM MAC address may be used to indicate which subscriber is to be intercepted:
configure cable intercept subscriber <CM MAC address> [disable|enable] md <IP address> udp <UDP
port> [tos <TOS byte>] until <mm/dd/yyyy/hour:min> [userid <string>] [password <string>]
[subscriber]
An example using the subscriber’s CM MAC:
configure cable intercept subscriber 0001.0203.aaaa md 192.168.100.199 udp 12345 until 06/19/2010
The md, udp, and until keywords are required when creating a new LI tap session. If no time is specified for the until
option, it defaults to 23:59, at which time the session will be removed. Use the disable option to create a tap session
