cable upstream connector
Tip
Use the
cable upstream max-ports
command to set the maximum number of upstream ports per
downstream before using the
cable upstream connector
command.
Table 2-10
shows the default port mapping.
The physical upstream ports can be assigned in any combination to a downstream, up to a maximum of
8 upstreams per downstream. If you have previously mapped an upstream port to a physical port using
the
cable upstream connector
command, you must first remove that mapping, using the
no
form of the
command, before changing it.
Examples
The following example shows how to configure a downstream (MAC domain) on the
Cisco uBR-MC5X20S card for 8 upstream ports:
Router#
configure terminal
Router(config)#
interface cable c8/1/0
Router(config-if)#
cable upstream max-ports 8
Router(config-if)#
cable upstream 0 connector 16
Router(config-if)#
cable upstream 1 connector 17
Router(config-if)#
cable upstream 2 connector 18
Router(config-if)#
cable upstream 3 connector 12
Router(config-if)#
cable upstream 4 connector 13
Router(config-if)#
cable upstream 5 connector 14
Router(config-if)#
cable upstream 6 connector 15
Router(config-if)#
cable upstream 7 connector 11
Router(config-if)#
exit
Router(config)#
exit
Router#
