5.2.5 Resetting the Board

This part describes how to reset the board. Resetting the board is a common measure of handling

the fault. Faults can be cleared by initializing the board.

Prerequisite

l The local maintenance terminal (LMT) is started.

l The user logs in to the GGSN9811 as an operator with the operation authority.

l The master and slave boards are in position and work at normal level.

Context

CAUTION

When resetting the master SPU or master SRU, pay attention to the following:

l If the slave board is in position and works at normal level, resetting the master board triggers

the handover of the master and slave boards. Then, the master board is reset. The slave

board serves as the master board, which enables that the users are online during board

resetting.

l If the slave board is not in position or faulty, resetting the master board causes that all users

of the board are off-line. Therefore, be cautious to perform this operation.l Resetting the board interrupts the ongoing service. Therefore, reset the board when the

traffic is light (such as midnight).

Procedure



GGSN9811.

2. Select a board to be reset. Right-click, and then choose Reset Board. The

Confirmationwindow is displayed. To reset the board, click Yes. Then, the systemreturns the execution results. To cancel the resetting, click No.

5.4.2 Using TRACERT

This part describes how to test the gateways passed through by the packet from the host to the

destination address. The TRACERTcommand is used to check whether the network connection

is normal and analyze where the fault occurs in the network.

5.4.1 Running PING

This part describes how to check the network connection by using PING.

Prerequisite


Context

The execution results include the following:

l Reply at the peer end to each ping packet. If the local end does not receive the response

packet within a specified period, Request time outis displayed. If the local end

receives the response packet, the information displayed includes the number of the bytes,

packet serial No., time to live (TTL), and response time.

l Comprehensive statistics information, including the number of transmitted packets, number

of received packets, percentage of packets without response, and minimum/maximum/

average duration of the responding time.

Procedure

Run PINGto check whether the network is connected and whether the device is accessible.

----End

Example

The following describes how to check whether the device is accessible device. In this example,

the IP address of the device is 10.110.84.207. The printouts show that the peer end responds to

each packet in time, which indicates that the device is accessible.

PING: IP="10.110.84.207";

RETCODE = 0 Execution succeeded

PING 10.110.84.207: 56 data bytes, press CTRL_C to break

Reply from 10.110.84.207: bytes=56 Sequence=1 ttl=255 time = 10 ms

Reply from 10.110.84.207: bytes=56 Sequence=2 ttl=255 time = 1 ms Reply from 10.110.84.207: bytes=56 Sequence=3 ttl=255 time = 10 ms

5.4.2 Using TRACERT

This part describes how to test the gateways passed through by the packet from the host to the

destination address. The TRACERTcommand is used to check whether the network connection

is normal and analyze where the fault occurs in the network.

Prerequisite


Context

The TRACERT process is described as follows: The source first sends a packet with TTL as 1,

so hop 1 sends back an Internet Control Message Protocol (ICMP) error message to specify that

the packet is not sent (TTL times out), and then the packet is resent with TTL as 2. Likewise,

hop 2 returns TTL timeout. This process continues until the packet reaches the destination. The

process is to record the source address of each ICMP TTL timeout message to provide the routes

that an IP packet adopts to reach to the destination.

The execution results include the following:

l If the response packet is not received within a specified period, Executing command

timed outis displayed. If the response packet is received with a specified period, the

information displayed includes the serial No. of each hop, IP address, and response time.

l If the packet cannot reach the next hop before the timeout (For example, the maximum

number of the hops is set), the serial No. of this hop and the character *are displayed.

Procedure

Run TRACERTto test the gateways through which the data packet passes from the host to the

destination address.

NOTE

It is recommended to enter the TTL value before using this command. This is to avoid timeout in the case

of unreachable network. If the timeout occurs, users cannot browse the required information.

----End

ExampleThis following describes how to check whether the device is accessible. In this example, the IP

address of the device is 10.70.12.40. The maximum number of hops is three. The printouts show

that the test cannot continue when the packet reaches the third hop.

TRACERT: MTTL=3, HOSTN="10.70.12.40";

RETCODE = 0 Execution succeeded
