cable freq-range
Interface Cable4/0 does not support Japanese frequency
Interface Cable5/0 does not support Japanese frequency
Router(config)# interface cable 6/0 ! This cable interface supports the Japanese range
Router(config-if)# cable upstream 0 frequency ?
<5000000-55000000>
Router(config-if)#
The following example shows how to configure the Cisco CMTS router for its default configuration
(DOCSIS upstream frequency range of 5 MHz to 42 MHz). (No warning messages are displayed with
this configuration because all cable interface line cards support the basic DOCSIS frequency range.)
After giving this command, the cable upstream frequency command shows the valid range of upstream
frequencies as being the DOCSIS range:
Router# configure terminal
Router(config)# cable freq-range north-american
Router(config)# interface cable 3/0
Router(config-if)# cable upstream 0 frequency ?
<5000000-42000000>
Router(config-if)#
The following example shows all of the commands that are needed to configure the cable interface and
upstream on a Cisco uBR-MC28U/X cable interface line card to support a frequency in the EuroDOCSIS
upstream frequency range of 5 MHz to 65 MHz:
Router# configure terminal
Router(config)# cable freq-range european
Router(config)# interface 3/0
Router(config-if)# cable downstream annex a
Router(config-if)# cable upstream 0 frequency 62500000
Router(config-if)#
The following example shows the cable freq-range command failing because an upstream is configured
for a frequency that is invalid for the new range. The upstream must be reconfigured before the cable
freq-range command can be given successfully.
Router# configure terminal
Router(config)# cable freq-range japanese
%%Interface Cable 3/0/U0 has invalid frequency (62500000 Hz) for specified range
%%Set upstream frequencies within range prior to changing freq-range
Router(config)# interface 3/0
Router(config-if)# cable upstream 0 frequency 38600000
Router(config-if)# exit
Router(config)# cable freq-range japanese
Router(config)#
