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
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
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.
logical-port
Specifies the upstream port number for the logical port assignment. The
number of logical ports is configured with the
cable modulation-profile
command, and the valid range is from 0 to one less than the current value
set with the
cable modulation-profile
command.
Tip
The default value for
max-ports
command is 4, which means the
default range for
logical-port
is 0 to 3.
physical-port
Specifies the upstream port number for the actual physical port to be
assigned. The valid range is 0 to 19, with no default.
Release
Modification
12.2(15)BC1
This command was introduced to support the Cisco uBR-MC5X20S
cable interface line card.
12.2(15)BC2
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.
