1.3 Data Configuration Methods

Configuration Mode

With ZXUN xGW as the hardware platform, ZXUN GGSN uses on-line MML configurationmode.

Enter ZXUN GGSN configuration mode by the following steps:

1. On the debugging terminal, connect to the MPU board by using the SecureCRTsoftware in Telnet mode. The prompt character xGW> appears, indicating asuccessful connection.

2. At the xGW> prompt character, enter enable, and enter the user name and thepassword for login. The prompt character changes to xGW#, indicating that you havelogged in to the MPU board successfully.

Note:

You can use the default user name of en or customized user name and password tolog in to the MPU board.

In configuration mode, use the username command to create a new user name. Forexample, use the following command to create a user, with the user name and thepassword both being zte, and with the privilege being 15.

xGW(config)#username zte zte privilege 15

3. At the xGW# prompt character, enter configure terminal. The prompt characterchanges to xGW(config)#, indicating you have entered configuration managementmode.

4. At the xGW(config)# prompt character, enter xgw. The prompt character changes toxGW(config-xgw)#, indicating you have entered xGW configuration mode.

xGW(config-xgw-ggsn)#virtual-gtp-ip-address 192.168.50.10 vrf RP

2.2.3 Configuring the CU GroupConfigure the CPU of the Charging Unit (CU) daughter card, and configure the alarmthreshold.

Only the CPU whose daughter card No. on the CSU board is XSFC can be configuredas the CU, and generally it is the CPU 2 on the CSU; therefore, the CPU location is shelf0/slot **/CPU 2 when configuring the CU.

There is a hard disk on the CU daughter card, which is used to save the CDRs.

CU does not need to configure the backup mode of the CPU group, and all CPUs are atactive status by default. Where there are multiple CU groups, system will automaticallychoose the CU group with a smaller group ID as the preferred CU group for saving CDRs.

Prerequisite

Make sure that there is a CPU as XSFC in the daughter card No. on the CSU board.

Steps

1. In the CU configuration mode, create and enter the CU group.

The command syntax for creating and entering the CU is: group , asdescribed in Table 2-12.

2-6



Table 2-12 Description of Commands for Creating and Entering the CU Group


number CU Group ID, ranging 1~250.

2. Carry out the following command under the CU group mode to add the CPU to the CUgroup.

The command syntax for adding the CPU to the CU group is: cpu , asdescribed in Table 2-13.

Table 2-13 Description of Commands for Adding the CPU to the CU Group


Location CPU location:

l Shelf: shelf

l Slot: slot

l cpu: CPU ID

Note:



3. Configure the CU ageing time.

The command syntax for configuring the CU ageing time is: ageing-time{|default}, as described in Table 2-14.

Table 2-14 Description of Commands for Configuring the CU Ageing Time


3-30 Value of CU ageing time, ranging 3~30. When the hard disk space on the CU is

insufficient, CDRs before the ageing time will be deleted firstly.

default Default ageing time is 7 days.

End of Steps

Example

1. To go to the CU configuration area, use the command below:

xGW(config-xgw)#cu

2. To create and enter the CU group with group ID as 1, use the command below:

2-7



xGW(config-xgw-cu)#group 1

3. To add the CPU with shelf 0/slot 13/CPU 2 in the CU group 1, use the command below:

xGW(config-xgw-cu-group)#cpu 0/13/2

4. Exit the CU group configuration mode, use the command below:

xGW(config-xgw-cu-group)#exit

5. To create the CU group 2, and add the CPU with shelf 0/slot 15/CPU 2 in this group,use the command below:

xGW(config-xgw-cu)#group 2

xGW(config-xgw-cu-group)#cpu 0/15/2

6. Exit the CU group configuration mode, use the command below:

xGW(config-xgw-cu-group)#exit

7. To configure the CU ageing time according to the default mode, use the commandbelow:

xGW(config-xgw-cu)#ageing-time default

2.3 Configuring the IP Protocol StackThe real interface is the physical interface, which is used for communication of GGSNbottom layer links, and responsible for communication among the GGSN and other NEs.

Steps

1. Configure the physical interface in global configuration mode.

a. Use the command show ip interface to query the real interface status.

If all AdminStatus are up, the PFU board is started successfully. The following isan example of output result of the physical interface status:

gei-0/10/0/1 AdminStatus is up, PhyStatus is down, line protocol is down

IP MTU is 1500 bytes

gei-0/10/0/2 AdminStatus is up, PhyStatus is up, line protocol is up

Internet address is 192.136.1.1/16

Broadcast address is 255.255.255.255

Secondary address is 194.136.1.1/16










2-8





gei-0/10/0/7 AdminStatus is up, PhyStatus is up, line protocol is up


b. Enter the interface status.

The syntax of the command used to enter the interface status is interfaceinterface-location, or interface gei- interface-location, or interface xgei-interface-location. The involved parameters are as described in Table 2-15.

Table 2-15 Description of Commands for Entering the Interface Status


interface-location Port location information in the format of shelf/slot/subunit

type/port.

Note:

To enter the interface status, use the interface gei- command for 10M or 1000M or100M interface, the interface xgei- command for 10G interface.

c. To add an interface IP address.

The syntax of the command for adding an interface IP address is: ip address . The involved parameters are as described in Table 2-16.

Table 2-16 Description of Commands for Adding the Interface IP Address


IP-Address IP address of the real interface.

Mask Mask address of the real interface.

d. Set the MAC address offset.

The syntax of the command for setting the MAC address offset is: interface mac-address offset . The involved parameters are as described in Table 2-17.

Table 2-17 Description of Commands for Setting MAC Address Offset


Number Number of the offset bytes of the MAC address.

2-9



Note:

The PFU has multiple optical ports or electrical ports, and their MAC addressesmay be the same; therefore, offset their MAC addresses for N bytes duringconfiguration to ensure no-repeat.

2. Configure the route in global configuration mode.

a. Set the default route of the ZXUN GGSN.

The syntax of the command for setting the default route is: ip route 0.0.0.0 0.0.0.0Gateway IP address

b. Set the non-default route of the GGSN.

The command syntax for configuring the non-default route of the GGSN is: iproute , as described in Table 2-18.

Table 2-18 Description of Commands for Setting Non-default Route of GGSN


IP-Address Destination IP address of the non-default route.

Mask Mask of the non-default route.

Next Hop Gateway IP address of the non-default route, which must be in the

same network segment with the IP addresses of the interface using

this route.

3.1 Description of the basic service configurationThis chapter describes the basic operations of the configuration of the ZXUN GGSN,including the following two parts.

l Configuring the Dynamic IP Pool

Before the mobile terminal subscriber accesses the external network, the GGSNshould allocate an address to this subscriber.

ZXUN GGSN allocates local subscriber with addresses through a dynamic addresspool.

l Configuring the APN

APN identifies the external PDN or type of business that connected to ZXUN GGSN.

Configure the APN is used to set the APN's name and other configuration.
