cable modem vendor
To associate the name of a vendor with its Organizational Unique Identifier (OUI), use the cable modem
vendor command in global configuration mode. To remove the association of the vendor name with its
OUI, use the no form of this command.
cable modem vendor OUI [vendor-name]
no cable modem vendor OUI [vendor-name]
Defaults A default database contains approximately 300 OUIs associated with approximately 60 vendor names.
Command Modes Global configuration
Command History
OUI Specifies the Organizational Unique Identifier (OUI). An OUI is the
first 3 octets (3 bytes, 6 hexadecimal digits) of the CM MAC address and
typically indicates the vendor for the CM. The octets can be specified as
one string (for example: 000102), or each octet can be separated by a
hyphen, period, or colon (for example: 00-01-02 or 00:01:02 or
00.01.02).
Note You can use either a period or colon as the separator between
octets when manually entering this command, but the
command that is written to the running and startup
configuration files will always use a period.
vendor-name (Optional) Specifies an arbitrary string identifying the vendor for this
OUI.
Release Modification
12.2(8)BC2 This command was introduced.
Usage Guidelines The cable modem vendor command allows you to associate an arbitrary string with an OUI to identify
the vendor of the associated CM. The vendor name is then displayed as part of the show cable modem
vendor command.
The show cable modem vendor command uses a default database of approximately 300 OUIs. If the
OUI and vendor are not in that database, the show cable modem vendor command displays the OUI as
the vendor name, but you can use the cable modem vendor command to associate a vendor name with
the new OUI.
If you specify an OUI with the cable modem vendor command that already exists in the OUI database,
the previous value is overwritten with the new value. You can use the default prefix to restore the
original value for an OUI in the default database.
You can also use the no cable modem vendor command to remove the association between an OUI and
a vendor name. The show cable modem vendor command then displays only the OUI as the vendor
name.
