Cisco CMTS Configuration Commands
cable upstream connector
To map an upstream port to a physical port on the Cisco uBR-MC5X20S/U cable interface line card for
use with a particular downstream, use the cable upstream connector command in cable interface
configuration mode. To remove the mapping and shut down the upstream port, use the no form of this
command.
Syntax Description
logical-port
physical-port
Defaults
By default, the Cisco uBR-MC5X20S/U cable interface line card uses a fixed configuration, in which
each downstream is allocated four upstream ports.
Command Modes
Interface configuration (cable interface only)
Command History
Release
12.2(15)BC1
12.2(15)BC2
Usage Guidelines
The cable upstream connector command changes the default assignment of upstream ports to MAC
domains on the Cisco uBR-MC5X20S/U card. This command creates a virtual upstream for a
downstream and assigns it to a particular physical port.
The default port mapping assigns four upstream ports to each of the downstream ports (MAC domains).
The ports are assigned sequentially, in the order in which they appear on the card's front panel.
The no version of this command removes the upstream port mapping and shuts down the upstream port.
The port must be remapped to another physical port before it can come online again.

Specifies the upstream port number for the logical port assignment. The
number of logical ports is configured with the
command, and the valid range is from 0 to one less than the current value
set with the
Tip
Specifies the upstream port number for the actual physical port to be
assigned. The valid range is 0 to 19, with no default.

The default value for max-ports command is 4, which means the
default range for logical-port is 0 to 3.
Modification
This command was introduced to support the Cisco uBR-MC5X20S
cable interface line card.
Support was added for the Cisco uBR-MC5X20U card. Also, the
entAliasMappingTable in the ENTITY-MIB was updated to show the
mapping between the physical upstream connectors and the logical
upstream connectors.
