Configuring a Media Gateway Node

System management screens configure the overall parameters of an Cisco MGX 8260 Media Gateway node and define its interactions with other nodes and servers. You perform the following tasks at the node level:

• Set and view media gateway parameters

• Synchronize the media gateway clock

• Enforce security through user accounts

Logging On

Before you can configure the Cisco MGX 8260 Media Gateway, you must log on as a user with the privilege to change system parameters. You need superuser privileges to change most system-level settings.

To log on, follow these steps:

Step 2 Connect to the Cisco MGX 8260 HTTP server using the conventional http:// notation. You need to know the host name or IP address for the desired Cisco MGX 8260 node. This is the management IP address you set while initializing the hardware.

The logon screen is displayed.

Step 3 In the User Id field, enter SuperUser.

Step 4 In the Password field, enter cisco.

The Chassis View screen opens:

From the navigation pane, select the operation you want to perform. To set node parameters, click Node and then click a submenu item.

Configuring System Parameters

To view or change system-wide parameters, follow these steps:

Step 2 Click System.

The system settings form opens:

The form displays the system up time, a read-only value, representing the length of time the system has operated without interruption.

Step 3 Change the following system parameters:

Parameter	Description	Sample
Node Name	The name of this node. Enter as many as 15 characters.	Cisco MGX 8260
Node Number	The node number of this shelf.	1
BackPlaneType	The Cisco MGX 8260 backplane type.	(read only)
System Contact	The name of the system administrator.	William
System Location	The physical location of the Cisco MGX 8260 chassis.	West
Rack Number	The rack number of this shelf.	1
Node Type	The node type.	(read only)
BackPlane Serial Number	The backplane serial number.	(read only)
System Description	A user-defined description of the system.	(read only)
System Time Zone	Time zone, expressed as the number of hours before or after GMT1.	(see Table 6-1)
Set System Date	The system date, specified in month (mm), day (dd), and year (yyyy) fields.	Month: 12 Day: 31 Year: 1999
Set System Time	The current time, set in hour, minute, and second fields.	Hour:12 Minute:00 Second:00

1GMT = Greenwich Mean Time

Step 4 Click Modify. The system applies the changes.

Synchronizing the System Clock

The clock module has three synchronization options:

• Building Integrated Timing Source (BITS)---A high-quality timing source that synchronizes all equipment in the building

• Line---A clock derived from a receive signal on one of the lines

• Local---An internal Cisco MGX 8260 timing source

You assign one clock source as the primary source and another as the secondary source. When using the line clock, specify both the line and slot associated with the source.

During normal operation, the primary clock is the active source and the secondary clock is the backup source. If the active source fails, the Cisco MGX 8260 Media Gateway switches to the backup clock and reports an alarm. You can also switch to the backup source manually. This section explains how to set the primary and secondary clocks and view clock status.

Viewing Clock Parameters

The clock parameters include:

• Status of the primary and secondary clocks

• The current clock source

• The lowest stratum level of the current clock source

To view clock source information, follow these steps:

Step 2 Click Clock Source.

The Clock Source screen opens.

Step 3 Interpret clock settings as follows:

Setting	Description
Primary and Secondary Clock Source Slot	The slot number for the clock source
Primary and Secondary Clock Source Line	The line number for the clock source
Primary and Secondary Clock Source Type	The clock source type: broadBandClk narrowBandClk externalClk internalClk
Primary and Secondary Clock Status	The clock status: OK noClock inaccurate
Current Clock	The current clock source: primary secondary internal
Current Clock Stratum	The level of Stratum clock: level 3 level 4
Clock Source Card Type	The type of card for the clock source: bits oc3

Note The selected clock source may not be the active clock if the selected clock fails.

Setting the Primary and Secondary Clock Source

To set the clock source, follow these steps:

Step 2 Click Clock Source.

The Clock Source screen opens.

Step 3 Click Primary Setting.

The primary clock source setting dialog box opens.

Step 4 Change the clock parameters as follows:

Value	Description	Sample
Primary Clock Source Slot	The slot supplying the clock. This argument is ignored if the clock source type is external (BITS) or internal. Valid entries: 1 through 16	---
Primary Clock Source Line	The line number for the clock source. This argument is ignored if the clock source type is external (BITS) or internal. Valid entries: DS1 line: 1 through 16. DS3 line: 501 through 506.	---
Primary Clock Source Type	The clock source type: broadBandClk narrowBandClk externalClk internalClk	xternalClk (BITS)
Clock Source Card Type	The type of card for the clock source: bits oc3	bits

Step 5 Click Modify.

Step 6 Click Back.

Step 7 Click Secondary Setting.

The Secondary clock source setting dialog box opens.

Step 8 Change the secondary clock parameters as follows:

Value	Description	Sample
Secondary Clock Source Slot	The slot supplying the clock. This argument is ignored if the clock source type is external (BITS) or internal. Valid entries: 1 through 16	11
Secondary Clock Source Line	The line number for the clock source. This argument is ignored if the clock source type is external (BITS) or internal. Valid entries: DS1 line: 1 through 16. DS3 line 501 through 506.	1
Secondary Clock Source Type	The clock source type: broadBandClk narrowBandClk externalClk internalClk	broadBandClk
Clock Source Card Type	The type of card for the clock source: bits oc3	oc3

Step 9 Click Modify.

The system updates the clock settings.

Switching the Clock Source

You can force the system to switch between the primary and secondary clock sources. During normal operation, the current clock is the primary clock. Typically you switch clocks to restore the primary clock after an automatic switchover to the secondary clock.

To switch to the secondary clock, follow these steps:

Step 2 Click Clock Source.

The Clock Source screen opens.

Step 3 On the Clock Source screen, click Switch Clock Source; then confirm your action.

Working with User Profiles

The Cisco MGX 8260 Media Gateway enforces security with user accounts and access levels. Users must log on before performing any task, and authenticated users can perform only those tasks permitted by their access level. The Cisco MGX 8260 Media Gateway supports as many as 20 user accounts, each with access privileges ranging from full control to guest.

Table 6-2: User Accounts and Access Privileges

Access Level	Account type	Command groups
