The ETEP cannot ping the 

management workstation. 
The request times out or returns an 

“Operation not permitted” message.

Check whether the trusted host feature is enabled on the 

ETEP. 
• Check the configuration for the trusted workstation. Pings 

are not allowed when the ICMP is unchecked in the trusted 

host configuration. 

• You can disable trusted hosts from ETEMS or by issuing 

the disable-trusted-hosts CLI command.

Cannot access the ETEP 

management port using SSH. 

• Check the setting for the ssh-enable command. It must be 

set to true. 

• Enabling FIPS mode or strong password enforcement on 

the ETEP causes the SSH daemon to restart, closing all 

open SSH connections. After enabling either of these 

features, wait 30-60 seconds before trying to re-establish 

an SSH connection to the ETEP management port. 

• If you used SSH to manage the ETEP prior to replacing a 

certificate or entering FIPS mode, you may not be able to 

establish an SSH session after the configuration change. 

To correct this, clear the known host entry for your SSH 

client and retry.

Can’t change the management port 

IP address on the appliance from 

ETEMS.

• The management port IP address must be unique. In the 

Appliances view, check for duplication.

• Verify that the appliance’s management port is not in use 

by a CLI session or the appliance web interface.

Editing the management IP address 

or date returns a 

 status.

• Refresh the appliance status. 
• If the refreshed status is still not equal, compare the 

ETEMS and appliance configurations (Tools > Compare 

Config to Appliance) to determine which items are 

different. Make any necessary adjustments to synchronize 

the two configurations.

Appliance setting is not displayed as 

a configuration option in ETEMS. 

• Not all features are supported in each appliance model or 

software revision. Check the model number and software 

version configured for the appliance, then refer to the 

Factory Default tables in the configuration chapter for your 

appliance model to check feature availability.

When configuring a new appliance, 

changing the product family 

(appliance model) causes other 

configuration settings to be 

discarded.

• To carry configurations forward when changing the product 

family, save the configuration prior to changing the product 

family.

Can’t change the appliance date or 

time from ETEMS.

• When the SNTP client is enabled on the appliance, you 

cannot change the appliance date or time. To modify the 

date or time, disable SNTP, push the configuration to the 

appliance, and then set the date (Edit > Date).
