3.3.2 Setting Modem Community Strings — DOCSIS 2.0+IPv6 Method
Set the modem community strings with the DOCSIS Configuration File for a IPv6 network by
including the following SNMP parameters:
TLV Type TLV Parameter Description Value
53 SNMPv1v2c Coexistence Configuration This object specifies the SNMPv1v2c Coexistence Access
Control configuration of the CM. This TLV creates entries in
SNMPv3 tables as specified in [DOCSIS OSSIv3.0]
Composite
53.1 SNMPv1v2c Community Name This sub-TLV specifies the Community Name (community
string) used in SNMP requests to the CM.
Text
e.g. AlphaRead
53.2 SNMPv1v2c Transport Address Access This sub-TLV specifies the Transport Address and Transport
Address Mask pair used by the CM to grant access to the
SNMP entity querying the CM.
Variable
53.2.1 SNMPv1v2c Transport Address Specifies the Transport Address to use in conjunction with
the Transport Address Mask used by the CM to grant access
to the SNMP entity querying the CM. Length is 6 bytes for
IPv4 and 18 bytes for IPv6. Two additional bytes are added
to the IP address length for the port number.
Transport Address
0.0.0.0/0
or
0:0:0:0:0:0:0:0/0
53.2.2 SNMPv1v2c Transport Address Mask Specifies the Transport Address Mask to use in conjunction
with the Transport Address used by the CM to grant access
to the SNMP entity querying the CM. Length is 6 bytes for
IPv4 and 18 bytes for IPv6. Two additional bytes are added
to the IP address length for the port number.
Transport Address Mask
0.0.0.0/0
or
0:0:0:0:0:0:0:0/0
53.3 SNMPv1v2c Access View Type Specifies the type of access to grant to the community name
of this TLV. If not specified, default read-only is used.
1=Read-only
2=Read-write
53.4 SNMPv1v2c Access View Name Specifies the name of the view that provides the access
indicated in sub-TLV SNMPv1v2c Access View Type.
String
e.g.docsisManagerView
MIB Parameter Object ID Description Value

server
e.g. 10.20.30.40
docsDevNmAccessIpMask 1.3.6.1.2.1.69.1.2.1.3.x Must be set to 255.255.255.255 per RFC 4639 255.255.255.255
docsDevNmAccessCommunity 1.3.6.1.2.1.69.1.2.1.4.x Community string used by NMS to query
Communications Module
alphanumeric string
docsDevNmAccessControl 1.3.6.1.2.1.69.1.2.1.5.x Level of SNMP access to DSM3 Series from
IP address specified in
docsDevNmAccessIpMask
4=Read/Only plus Trap
5=Read/Write plus Trap
6=Trap only, no SNMP access
docsDevNmAccessInterfaces 1.3.6.1.2.1.69.1.2.1.6.x Specifies the set of interfaces from which
requests from this NMS will be accepted
0x40 : Cable interface (typical)
0x80 : Ethernet interface
0xC0 or 0x00 : Both interfaces
docsDevNmAccessStatus 1.3.6.1.2.1.69.1.2.1.7.x Controls and reflects the status of rows in
this table

3.3.3 Setting SNMP Trap Destination Addresses — DOCSIS 2.0 (IPv4) Method
Set the SNMP Trap Destination Addresses via the DOCSIS Configuration File by including the
following SNMP parameters:
Table 3-3, Trap Destination Addresses — DOCSIS 2.0 (IPv4) Method
Note: X denotes the index of the SNMP entry
Table 3-2, Modem Community String Parameters — DOCSIS 2.0+IPv6 Method
