Action: To clear the setting, reboot modem or force a modem reauthorization through the
authorization MIB.
ANM_DOCSIS_B302_6
Auth Invalid — Invalid key sequence number
CM Authorization
Problem: The authorization key sequence number included in the TEK request did not match the
list of valid current authorization keys for the respective modem.
Action: There is no corrective action that can be taken. The system itself will recover the error.
ANM_DOCSIS_B302_7
Auth Invalid — Message authentication Failure
CM Authorization
Problem: The message authentication field (HMAC) in the TEK request was not valid.
Action: There is no corrective action that can be taken. The system will recover the error itself.
ANM_DOCSIS_B303_0
Unsupported crypto suite
CM Authorization
Problem: There are encryption algorithms that the CM can support that the C4/c CMTS does not.
Action: There is no corrective action that can be taken. As long as the CM and C4/c CMTS support
at least one common algorithm, the system will operate properly. If the Devices in the system are
certified, this will not be an issue.

Key Reject — No information
Traffic encryption key (TEK) exchange
Problem: The respective modem’s key request has been rejected for an unspecified reason.

TEK reject error string MIB table entry. If the reason can be corrected, fix and reboot the modem.
ANM_DOCSIS_B501_3
Key Reject — Unauthorized SAId
TEK exchange
Problem: This trap indicates that the respective modem’s authorization request has been
rejected. The modem has requested keying information for a flow it has not been authorized for.
Action: The internal C4/c CMTS reason for the reject will be displayed in the modem’s respective
TEK reject error string MIB table entry. If the reason can be corrected, fix and reboot the modem.
