3.2.4 CLI Logins Tab

The CLI Login Manager allows the user to specify a list of CLI username/password pairs that will be used by the Discovery

Process to determine the CLI username and password for individual devices. The username and password discovered for each

device are used for all CLI interactions with the device.

All managed devices are shipped with a factory-default CLI username and password, and customers are encouraged to change

these for security reasons.

Caution: As mentioned in Section 1.6.3 there is a user name and password used to access the device, and

this name/password is used by all NMS users when accessing a device. To enable NMS users to

query and control a device, the device name and password must be at a security officer level.

Failure to do so may make certain operations performed at the NMS on a device to fail.

Once a device has been discovered by SNMP, more detailed discovery requiring a CLI login is required to manage the device.

The NMS attempts to log into each device until it either discovers an accepted login or all login attempts are rejected. The login

sequence generally follows the order of the logins in the table. The order may be modified by selecting a row and then clicking

on the up or down buttons.

The login sequence can be overridden by the Hints field. Hints are a comma-separated list of device category, sysLocation, IP

address, and subnets (in x.x.x.x/bits notation). Login parameters for a device that matches any of the hints will be attempted

before any other login parameters. If there are more than 1 login entry with matching hints, they will be attempted in the

sequence from the list.

The NMS will retry each user id up to 5 minutes if it gets connection-refused errors (in case it just came up and needs more

time to finish initializing telnet and/or ssh services). If the NMS never gets connected, it will raise a discovery failure alarm.
