Syntax Description:
Command Modes Privileged EXEC
Command History
OL-1581-05
debug cable-modem bpkm
To display information about Baseline Privacy Interface (BPI) key management, use the debug
cable-modem bpkm command in privileged EXEC mode. To disable BPI debugging, use the no form
of this command.
Cisco uBR904, uBR905, uBR924, uBR925 cable access routers, Cisco CVA122 Cable Voice Adapter
debug cable-modem bpkm {errors | events | packets}
no debug cable-modem bpkm {errors | events | packets}
errors Debugs CM privacy errors.
events Debugs events related to cable baseline privacy.
packets Debugs baseline privacy packets.
Release Modification
11.3(4)NA This command was introduced for the Cisco uBR904 cable access router.
12.0(4)XI1 Support was added for the Cisco uBR924 cable access router.
12.0(5), 12.0(5)T This command was removed from normal access.
Usage Guidelines Baseline privacy key management exchanges take place only when both the router and the CMTS are
running code images that support baseline privacy, and the privacy class of service is enabled via the
configuration file that is downloaded to the cable access router. Baseline privacy code images for the
router contain k1, k8, or k9 in the code image name.
In Cisco IOS Release 12.0(5) and later releases, this command is available only under the direction of
TAC or field service, and should be used only while debugging CM operation. Displaying debugging
messages consumes system resources, and turning on too many messages could negatively affect system
performance.
Examples The following example shows typical debug output when the CMTS does not have privacy enabled:
Router# debug cable-modem bpkm errors
cm_bpkm_fsm(): machine: KEK, event/state: EVENT_4_TIMEOUT/STATE_B_AUTH_WAIT, new state:
STATE_B_AUTH_WAIT
cm_bpkm_fsm(): machine: KEK, event/state: EVENT_4_TIMEOUT/STATE_B_AUTH_WAIT, new state:
STATE_B_AUTH_WAIT
%LINEPROTO-5-UPDOWN: Line protocol on Interface cable-modem0, changed state to down
cm_bpkm_fsm(): machine: KEK, event/state: EVENT_1_PROVISIONED/STATE_A_START, new state:
