All counters are stored in nonvolatile storage so that they are retained across
router reboots and power cycles.
The counters for a specific user can be reset to zero using the command:
RESET USER=login-name
The counters for all users, the global counters, or all counters can be reset to
zero with the command:
RESET USER COUNTER={USER|GLOBAL|ALL}
Semipermanent Manager Port
It is sometimes desirable to have an asynchronous port that has MANAGER
privilege after a router reboot, without a manager having to log on. An
asynchronous port can be set to default to MANAGER privilege using the
command:
SET MANAGER PORT=port-number
Only one port may be a semipermanent manager port. By default, no
semipermanent manager port is defined. This command is defined as one of
the security commands (see “Database Security” on page 1-15).
When the router boots with a semipermanent manager port configured, the
MANAGER account is automatically logged in to the port. The port has full
MANAGER privilege and there is no restriction on Telneting from the port.
The security timer is reset so that the first time a security command is entered
the user will be challenged for the password for the MANAGER account.
RADIUS
RADIUS (Remote Authentication Dial In User Service) is a protocol for
transferring authentication, configuration and accounting information between
a Network Access Server (e.g. a router) which desires to authenticate its links,
and a shared RADIUS Server. The RADIUS (authentication) server manages a
database of users and provides authentication (verifying user name and
password) and configuration information (e.g. IP address, subnet mask, etc.) to
the client. The RADIUS (accounting) server stores accounting information
about past sessions.
The router acts as a RADIUS client, sending requests to a defined list of
RADIUS servers. Router modules use RADIUS in different ways depending on
their individual requirements. See the relevant chapter for specific details of
how RADIUS is used by the router. For example, ISDN and ACC can be
configured to use RADIUS to authenticate a call and return information such as
the IP address and network mask to be used to complete the call.
A RADIUS server is added or deleted using the commands:
ADD RADIUS SERVER=ipadd SECRET=secret
DELETE RADIUS SERVER=ipadd
The list of known RADIUS servers is displayed using the command:
SHOW RADIUS
