CONFIGURING SYSTEM PARAMETERS
These configuration parameters affect system functions for the modem. Other system parameters used to manage or troubleshoot the modem (updating modem software, for example) are in “Managing the Modem” on page
Before You Begin
Determine the following before changing system parameters:
•If secured management access is required for the modem, add users and assign one of three predefined secu- rity levels: Default, Engineer, or Super User.
•If SNMP access to the modem is required, add SNMP communities with either read or write access.
•Add the IP address for the network default router through which packets are forwarded.
•If static routes will be used to predetermined destinations, identify the destination host or network IP address. Also, identify the next hop gateway IP address for devices on your LAN (for example, the modem LAN port IP address).
•If spanning tree protocol is required, based on one or both of the following conditions, then enable it:
–RFC
–there are multiple bridging devices on a LAN with more than one physical path connecting them and you want to prevent loops
Otherwise, disable spanning tree protocol.
Assigning User Access
The modem provides secure access for managing and viewing modem configuration. Three levels of access are predefined and can be assigned to users you set up. These security logons are required for access to the Web interface or to access the command line interface through either the console port or through a telnet session. For the three levels of predefined access, it is recommended that you change the passwords for all three accesses to secure the modem for management. The following procedures show how to add, modify, or delete user accounts.
