Module: DOCS-SEC-MIB
OID (symbolic): DOCS-SEC-MIB::docsSecCmtsEncryptEncryptAlgPriority
OID (numeric): 1.3.6.1.4.1.4491.2.1.11.1.2.1
Node type: OBJECT-TYPE
Type: SnmpTagList
Access: read-write
Description: This attribute allows for configuration of a prioritized list of encryption algorithms the CMTS will use when selecting the primary SAID encryption algorithm for a given CM. The CMTS selects the highest priority encryption algorithm from this list that the CM supports. By default the following encryption algorithms are listed from highest to lowest priority (left being the highest): 128 bit AES, 56 bit DES, 40 bit DES. An empty list indicates that the CMTS attempts to use the latest and robust encryption algorithm supported by the CM. The CMTS will ignore unknown values or unsupported algorithms.
What is docsSecCmtsEncryptEncryptAlgPriority?
Sets a prioritized list of encryption-algorithm tags (e.g. 128-bit AES, 56-bit DES, 40-bit DES) that the CMTS uses to pick the primary SAID encryption algorithm for each cable modem, choosing the highest-priority algorithm the modem supports. Leaving the list empty tells the CMTS to negotiate the strongest algorithm the modem can do instead of following a fixed order.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4491.2.1.11.1.2.1 snmpwalk -v2c -c public <target> DOCS-SEC-MIB::docsSecCmtsEncryptEncryptAlgPriority
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.4491.2.1.11.1.2.1.1 snmpget -v2c -c public <target> DOCS-SEC-MIB::docsSecCmtsEncryptEncryptAlgPriority.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.4491.2.1.11.1.2.1.1 s <value>
