By using Service Discovery and an FQDN, the SBC can maintain registration with an EMS server without the need for re-initiating whenever an EMS IP address changes. 

To enable dynamic Service Discovery of the EMS IP address, specify a fully qualified domain name (FQDN) as the target for EMS registration. Use the Ems IP Address Override option to specify a particular IP address that the SBC must use for EMS registration. You can specify up to 8 override addresses, one value per command. (Enter the command 8 times to enter all 8 override values.) These will override any other previously configured EMS registration settings. 

This configuration applies and is visible only in SBC SWe virtualized deployments.

For more information on using Service Discovery, refer to Service Discovery for Trap Target Destinations and EMS Registration. Refer to Configuring Service Discovery for Trap Target Destinations and EMS Registration for information on FQDN naming conventions.

Note

A reboot is required in order for changes to the FQDN name or to any IP Address Override values to take effect.

Command Syntax

Set Command Syntax


% set system ems
	emsFqdn <FQDN for EMS registration> 
	emsIpAddressOverride <IP address to override the FQDN>

Command Parameters

EMS FQDN parameters for Service Discovery



Parameter Name

Length/Range

Description

emsFqdn

1....128 characters

Specifies an FQDN (up to 128 characters) of the EMS server to use for EMS registration. Refer to Configuring Service Discovery for Trap Target Destinations and EMS Registration for information on FQDN naming conventions. Changing this value requires an SBC reboot to take effect.

emsIpAddressOverride

<ip address>

IP address enforced for the EMS registration.

You can specify up to 8 override addresses. These will override any other previously configured EMS registration settings.

Command Example

The following example sets the name of the FQDN of the EMS registration to “dev1._ems._tcp.example.com” and sets the IP address override to the value “11.12.13.14”. The show command displays the value of the EMS IP address. (A reboot is required for any set system ems command to take effect.)

% set system ems emsFqdn dev1._ems._tcp.example.com 

% set system ems emsIpAddressOverride 11.12.13.14

% commit

% show status system ems emsIpAddress
