1 NTP GNE driver description

1.1 Network timing servers in the Small Cell network

The Small Cell access points use network timing servers that run the Network Time Protocol (NTP)

for RF synchronization. The 5620 SAM Small Cell management solution supports Symmetricom

NTP server variants, such as the Symmetricom Time Provider 5000 server. The NTP GNE driver

allows the 5620 SAM to perform fault management of Symmetricomm NTP servers.

1.2 NTP GNE driver capabilities

The NTP GNE driver extends the 5620 SAM fault management support to Symmetricom NTP

servers so that related alarms can be viewed in the 5620 SAM GUI. The NTP GNE driver version

1.0.0 allows the 5620 SAM to perform fault management of NTP servers.

1.3 5620 SAM management

The 5620 SAM supports the following management operations for the NTP NE:

• Discovery

The 5620 SAM discovers the Symmetricom NTP server as an NTP NE.

• Link management

The 5620 SAM monitors the link to the NTP server, raises an alarm when the link fails and

retries automatically for link recovery. When the link is recovered, the 5620 SAM clears the

alarm.

• Fault management

The 5620 SAM normalizes fault events from the NTP server and shows them in the context of

the NTP NE in the 5620 SAM GUI. Alarms are also published over the 5620 SAM-O interface.

See the NTPAlarmDictionary.xml file for details.

• Reach-through to the NTP server from the 5620 SAM GUI

The 5620 SAM GUI provides a launch point option for users to open an SSH session with the

NTP.

2 Restrictions, limitations, issues

This is version 1.0.0 of the NTP GNE driver, and there are no closed issues to report.

2.2 Outstanding issues

This section describes problems that customers need to be aware of before deploying the NTP

driver in a live network or lab environment. This is version 1.0.0 of the NTP GNE driver, and there

are no outstanding issues to report.

NTP GNE driver description 5620 SAM


2.3 Limitations

The 5620 SAM support for the NTP in the Small Cell network does not include the following

functions:

• Alarm synchronization

• Configuration management

• Performance management

• Upgrade management

• Inventory management

• Software management

• NE administration and security management

• Auto-discovery

2.4 Restrictions

The following restrictions apply to the 5620 SAM support of the NTP:

• The NTP and the 5620 SAM must belong to the same time zone.

• The NTP does not have a mechanism to determine the sequence of faults or a way to identify

missing traps. Inform messages are not supported.

3 Discovery and management

3.1 Post-installation configuration

This section describes how to discover and use the NTP server in the 5620 SAM after the NTP

GNE driver was installed. See the 5620 SAM GNE Driver Installation Guide for details about

installing a GNE driver.

The following instructions are specific to the NTP server configuration and discovery. See the 5620

SAM User Guide chapter “Device commissioning and management“ for detailed procedures.

Configuring a generic NE profile for the NTP server

Perform the following steps:

1. Choose Administration→Generic NE Manager from the 5620 SAM main menu. The Generic NE

Manager form opens.

2. Click Create, and choose Create Generic NE Profile. The Generic NE Profile (Create) form

opens.

3. Configure the required parameters. The following table list the parameters that need to have

specific values for the NTP GNE. Leave blank the parameter values that are not specified in the

table.

4. Import the E1 interface type.

a. Click on the Interface Types tab.

b. Click Add. The Select Generic NE Interface Type form opens.

c. Choose the E1 interface type and click OK.

5. Click on the General tab.

6. Associate the NTP GNE driver with the NE profile.

a. In the Driver Module panel, click Select. The Select Driver Module — Generic NE Profile

form opens.

b. Choose the NTP driver that was installed on the 5620 SAM server and click OK.

7. Save your changes and close the forms.

Configuring an SNMP v2c mediation policy for the NTP GNE


1. Choose Administration→Mediation from the 5620 SAM main menu.

2. Click on the Mediation Security tab.

3. Click Create. The Mediation Policy (Create) form opens.

4. Configure all the required SNMP parameters.

• For Displayed Name, enter NTP.

• Set the Timeout parameter to 40000 milliseconds for the successful discovery of the NTP

GNE.

The mediation policy needs to be configured according to the NE configuration. The Security

Model, Port and Community String parameter values must match the values of the same

parameters configured on the NTP GNE.

5. Save your changes and close the forms.

Discovery and management 5620 SAM


Configuring a discovery rule for the NTP server


1. Choose Administration→Discovery Manager from the 5620 SAM main menu. The Discovery

Manager form opens.

2. Click Create. The Create Discovery Rule form opens.

3. On the Specify General Attributes page, enter NTP in the Description box and click Next.

4. On the Add Rule Elements page, click Create and assign an IP address for the NTP NE and

then click Next.

5. On the Configure Mediation Security page, choose the SNMP v2c mediation policy that you

configured, and click Finish.

After configuring the discovery rule, the NTP server appears as a GNE in the Equipment and Small

Cells views.
