Cisco CMTS Configuration Commands
cable upstream max-ports
To configure the maximum number of upstreams on a downstream (MAC domain) on a
Cisco uBR-MC5X20S/U cable interface line card, use the cable upstream max-ports command in
cable interface configuration mode. To reset the card to its default value of 4 upstreams per downstream,
use the no form of this command.

Usage Guidelines
Use this command to specify how many upstreams a downstream (MAC domain) will support on the
Cisco uBR-MC5X20S card, before using the
to physical ports on the card. The downstreams on a card can be configured for different maximum
upstream values.
After using this command, the valid range for upstreams on that cable interface will be from 0 to one
less than the maximum port value. For example, if you use the cable upstream max-ports 6 command
to specify a maximum of 6 upstreams for the downstream, the valid range for upstreams will be 0 to 5.
Examples
The following example shows how to configure all of the downstreams on a Cisco uBR-MC5X20S card
for a maximum number of 6 upstreams.
Router# configure terminal
Router(config)# interface cable c6/1/0
Router(config-if)# cable upstream max-ports 6
Router(config-if)# interface cable c6/1/1
Router(config-if)# cable upstream max-ports 6
Router(config-if)# interface cable c6/1/2
Router(config-if)# cable upstream max-ports 6
Router(config-if)# interface cable c6/1/3
Router(config-if)# cable upstream max-ports 6
Router(config-if)# interface cable c6/1/4
Router(config-if)# cable upstream max-ports 6
OL-1581-08
cable upstream max-ports n
no cable upstream max-ports n
The valid range is 1 to 8, with a default of 4.
Modification
This command was introduced to support the Cisco uBR-MC5X20S
cable interface line card.
Support was added for the Cisco uBR-MC5X20U cable interface line
card.
