Managing the CMTS
Managing consists of various system administration tasks, including those related to accounting, security, and
configuration. This is accomplished through in-band or out-of-band management or both. Management functions can use
telnet, SSH, SNMP, and other protocols.
In-band Management
This means that the telnet/ssh/snmp sessions are carried through the Ethernet interfaces on the RCM line card.
Pro: Access Control Lists (ACLs) can be applied to increase security
Con: In-band management uses the same interfaces as all the modem traffic.
To provision in-band management, permit and define a standard ACL by entering:
configure access-list 1 permit any
configure interface gigabitEthernet 17/0 ip scm access-group 1
configure ip scm access
Out-of-band Management
This means that the telnet/snmp sessions are carried through the Ethernet interfaces on the SCM card, so that
management traffic is not being carried on the same channels as data traffic.
Pro: The IPs can be put on a private network and only management traffic is carried on these links
Con: ACLs can not be applied to these interfaces. The interface is 10MBPS and half duplex. The C4c CMTS requires a reboot
if these parameters need to be changed.
To provision out-of-band management, enter the following commands:
