Activating The Upstream Ports; Activating Upstream Frequency Adjustment - Cisco 7246VXR - uBR Router Software Configuration Manual

Chapter 3 Configuring Cable Modem Interface Features

Activating the Upstream Ports

Each upstream port must be activated to enable upstream data transmission from the CMs on the HFC
network to the Cisco uBR7200 series CMTS.
The upstream cable interface does not operate until you either set a fixed upstream frequency or create
Note
and configure a spectrum group. Refer to the
details.
To activate the upstream ports, use the following commands in global configuration mode.
Command
Step 1
Router(config)# interface cable slot/port
Step 2
Router(config-if)# no cable upstream usport shutdown
Verifying the Upstream Ports
To determine if the upstream ports are activated or deactivated, enter the show interface cable command
for the upstream port just configured:
Router# show interface cable5/0
Cable5/0 is up, line protocol is up
Hardware is BCM3210 FPGA, address is 00e0.1e5f.7a60 (bia 00e0.1e5f.7a60)
Internet address is 1.1.1.3/24
MTU 1500 bytes, BW 27000 Kbit, DLY 1000 usec, rely 255/255, load 1/255
Encapsulation, loopback not set, keepalive not set
ARP type: ARPA, ARP Timeout 04:00:00
Last input 00:00:25, output 00:00:00, output hang never
Last clearing of "show interface" counters never
Queuing strategy: fifo
Output queue 0/40, 0 drops; input queue 0/75, 0 drops
5 minute input rate 0 bits/sea, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec

Activating Upstream Frequency Adjustment

To enable automatic upstream frequency adjustment for a specified cable interface, use the following
commands in cable interface configuration mode.

Received 3679 broadcasts, 0 runts, 0 giants, 0 throttles
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
