Setting Time Out of EXEC Privilege Mode

EXEC time-out is a basic security feature that returns the system to EXEC mode after a period of inactivity on the terminal lines.

To set time out, use the following commands.

• Set the number of minutes and seconds. The default is 10 minutes on the console and 30 minutes on VTY. Disable EXEC time out

by setting the time-out period to 0.

LINE mode

exec-timeout minutes [seconds]

• Return to the default time-out values.

LINE mode

no exec-timeout

The following example shows how to set the time-out period and how to view the configuration using the show config command from

LINE mode.

Dell(conf)#line console 0

Dell(config-line-console)#exec-timeout 0

Dell(config-line-console)#show config

line console 0

exec-timeout 0 0

Dell(config-line-console)#

Using Telnet to Access Another Network Device

To Telnet to another device, use the following commands.

NOTE:

The system allows 120 Telnet sessions per minute, allowing the login and logout of 10 Telnet sessions, 12 times in

a minute. If the system reaches this non-practical limit, the Telnet service is stopped for 10 minutes. You can use

console and SSH service to access the system during downtime.

• Telnet to a device with an IPv4 or IPv6 address.

EXEC Privilege

telnet [ip-address]

If you do not enter an IP address, the system enters a Telnet dialog that prompts you for one.

Enter an IPv4 address in dotted decimal format (A.B.C.D).

Enter an IPv6 address in the format 0000:0000:0000:0000:0000:0000:0000:0000. Elision of zeros is supported.

Lock CONFIGURATION Mode

The system allows multiple users to make configurations at the same time. You can lock CONFIGURATION mode so that only one user

can be in CONFIGURATION mode at any time (Message 2).

You can set two types of locks: auto and manual.
