-Login Banner—Enter text to display on the Login page before login. 
Click Preview to view the results.
-Welcome Banner—Enter text to display on the Login page after login. 
Click Preview to view the results.
NOTEWhen you define a login banner from the web-based configuration 
utility, it also activates the banner for the CLI interfaces (Console, Telnet, and 
SSH).
STEP  3Click Apply to save the values in the Running Configuration file.
Console Settings (Autobaud Rate Support)
The console port speed can be set to one of the following speeds: 4800, 9600, 
19200, 38400, 57600, and 115200 or to Auto Detection. 
Auto Detection enables the device to detect your console speed automatically, so 
that you are not required to set it explicitly. 
When Auto Detection is not enabled, the console port speed is automatically set to 
the last speed that was set manually at (115,200 by default).
When Auto Detection is enabled but the console baud-rate was not yet 
discovered, the system uses speed 115,200 for displaying text (for example, the 
boot-up information).
After Auto Detection is enabled in the Console Settings page, it can be activated 
by connecting the console to the device and press the Enter key twice. The device 
detects the baud rate automatically.
To enable Auto Detection or to manually set the baud rate of the console:
STEP 1Click Administration > Console Settings.
STEP  2Select one of the following:
•Auto Detection—The console baud rate is detected automatically.
•Static—Select one of the available speeds.

Defining Idle Session Timeout 
The Idle Session Timeout configures the time intervals that the management 
sessions can remain idle before they timeout and you must log in again to 
reestablish one of the following sessions:
• HTTP Session Timeout
•HTTPS Session Timeout
•Console Session Timeout
•Telnet Session Timeout
•SSH Session Timeout
To set the idle session timeout for various types of sessions:
STEP 1Click Administration > Idle Session Timeout.
STEP  2Select the timeout for the each session from the corresponding list. The default 
timeout value is 10 minutes.
STEP  3Click Apply to set the configuration settings on the device.

Rebooting the Device 
Some configuration changes, such as enabling jumbo frame support, require the 
system to be rebooted before they take effect. However, rebooting the device 
deletes the Running Configuration, so it is critical that the Running Configuration is 
saved to the Startup Configuration before the device is rebooted. Clicking Apply 
does not save the configuration to the Startup Configuration. For more information 
on files and file types, see the System Files section.
You can back up the configuration by using 
Administration > File Management > 
Copy/Save Configuration
 or clicking Save at the top of the window. You can also 
upload the configuration from a remote device. See the Download/Backup 
Configuration/Log section.
There are cases when you might prefer to set the time of the reboot for some time 
in the future. This could happen for example in one of the following cases:
•You are performing actions on a remote device, and these actions might 
create loss of connectivity to the remote device. Pre-scheduling a reboot 
restores the working configuration and enables restoring the connectivity to 
the remote device. If these actions are successful, the delayed reboot can 
be cancelled.
•Reloading the device cause loss of connectivity in the network, thus by 
using delayed reboot, you can schedule the reboot to a time that is more 
convenient for the users (e.g. late night).
To reboot the device:
STEP 1Click Administration > Reboot.
STEP  2Click one of the Reboot buttons to reboot the device.

Rebooting the Device

•Reboot—Reboots the device. Since any unsaved information in the Running 
Configuration is discarded when the device is rebooted, you must click Save 
in the upper-right corner of any window to preserve current configuration 
across the boot process. If the Save option is not displayed, the Running 
Configuration matches the Startup Configuration and no action is necessary.
The following options are available:
-Immediate—Reboot immediately.
-Date—Enter the date (month/day) and time (hour and minutes) of the 
schedule reboot. This schedules a reload of the software to take place 
at the specified time (using a 24-hour clock). If you specify the month 
and day, the reload is scheduled to take place at the specified time and 
date. If you do not specify the month and day, the reload takes place at 
the specified time on the current day (if the specified time is later than 
the current time) or on the next day (if the specified time is earlier than 
the current time). Specifying 00:00 schedules the reload for midnight. 
The reload must take place within 24 days.
NOTEThis option can only be used if the system time has either been set 
manually or by SNTP.
-In—Reboot within the specified number of hours and minutes. The 
maximum amount of time that can pass is 24 days.
•Reboot to Factory Defaults—Reboots the device by using the factory 
default configuration. This process erases the Startup Configuration file and 
the backup configuration file. 
The mirror configuration file is not deleted when restoring to factory 
defaults.
•Clear Startup Configuration File—Check to clear the startup configuration 
on the device for the next time it boots up.
NOTEClearing the Startup Configuration File and Rebooting is not the same 
as Rebooting to Factory Defaults. Rebooting to Factory Defaults is more 
intrusive.

Routing Resources
Use the Router Resources page to display TCAM allocation and modify total 
TCAM size. TCAM entries are divided into the following groups:
•IP Entries—TCAM entries reserved for IP static routes, IP addresses on the 
device, and IP hosts. Each type generates the following number of TCAM 
entries:
-IPv4 static routes—One entry per route
-IP Addresses—Two entries per IP address
-IP Hosts—One entry per host
•Non-IP Entries—TCAM entries reserved for other applications, such as 
ACL rules, CoS policers, and VLAN rate limits.
To view and modify router resources:
STEP 1Click Administration > Router Resources.
The following fields are displayed:
•Neighbors—Count is the number of neighbors recorded on the device and 
TCAM Entries is the total number of TCAM entries being used for neighbors.
•Interfaces—Count is the number of IP addresses on interfaces on the 
device and TCAM Entries is the total number of TCAM entries being used for 
the IP addresses.
•Routes—Count is the number of routes recorded on the device and TCAM 
Entries is the total number of TCAM entries being used for the routes.
•To t a l—Displays the number of TCAM entries which are currently being 
used.
•Maximum Entries—Select one of the following options:
-Use Default—The number of TCAM entries available for IP entries is 
25% of the TCAM size.
-User Defined—Enter a value.

You must save your current configuration before changing the TCAM Allocation 
Settings. 
NOTEA summary of the TCAM entries actually in use and available is 
displayed at the bottom of this page. For an explanation of the fields, see 
Viewing TCAM Utilization.
STEP  2Save the new settings by clicking Apply. This checks the feasibility of the TCAM 
allocation. If it is incorrect, an error message is displayed. If it is correct, the 
allocation is saved to the Running Configuration file and a reboot is performed.
Health
The Health page monitors the fan status on all devices with fans. Depending on the 
model, there are one or more fans on a device. Some models have no fans at all.
On devices on which a temperature sensor is assembled, for protecting the device 
hardware in case it overheats, the following actions are performed by the device if 
it overheats and during the cool down period after overheating:
Event Action
At least one temperature 
sensor exceeds the 
Warning thre sholdThe following are generated:
•SYSLOG message
•SNMP trap
At least one temperature 
sensor exceeds the Critical 
thresholdThe following are generated:
•SYSLOG message
•SNMP trap
The following actions are performed:
•System LED is set to solid amber (if hardware 
supports this).
•Disable Ports — When the Critical 
temperature has been exceeded for two 
minutes, all ports will be shut down.
•(On devices that support PoE) Disable the 
PoE circuitry so that less power is consumed 
and less heat is emitted.
