1: SNMP
Introduction:
The Simple Network Management Protocol (SNMP) is a standard
network management protocol widely used on TCP/IP networks. It
uses a central computer (a network management station) that runs
network management software to manage network elements.
There are three SNMP versions:
SNMPv1 & SNMPv2c & and SNMPv3
(S97 support both depend on configuration. V3 is default.)
2
1: SNMP
Three components are used in SNMP device management:
NM station: sends various query packets to query managed devices and receives alarms from
these devices.(HUAWEI eSight, HP OpenView,IBM Tivoli,…)
Agent: is a network-management process on a managed device. An agent has the following
functions:
– Receives and parses query packets sent from the NM station.
– Reads or writes management variables based on the query type, and generates and sends
response packets to the NM station.
– Sends an alarm to the NM station when triggering conditions defined on each protocol
module corresponding to the alarm are met. For example, the system view is displayed or
closed, or the device is restarted.
Managed device: is managed by an NM station and generates and reports alarms to the NM
station.( Router, Switch Firewall,…)

SNMP operations
Operation
Function
GetRequest
Retrieves the value of a variable. The NM station sends the request to
a managed device to obtain the value of an object on the device.
GetNextRequest
Retrieves the value of the next variable. The NM station sends the
request to a managed device to obtain the status of the next object on
the device.
GetResponse
Responds to GetRequest, GetNextRequest, and SetRequest operations.
It is sent from the managed device to the NM station.
GetBulk
Is an NMS-to-agent request, equaling continuous GetNext operations.
SetRequest
Sets the value of a variable. The NM station sends the request to a
managed device to adjust the status of an object on the device.
Trap
Reports an event to the NM station.

1: SNMP
Description of features supported by SNMP(1)
Operation
Function
Access control
This function is used to restrict a user's device administration rights. It
gives specific users the rights to manage specified objects on devices and
therefore provides fine management.
Authentication
and encryption
Packets transmitted between the NM station and managed devices are
authenticated and encrypted. This prevents data packets from being
intercepted or modified, improving data sending security.
Error code
Error codes are used to identify particular faults. They help an
administrator quickly locate and rectify faults. The larger the variety of
error codes, the more greatly they help an administrator in device
management.
Trap
Traps are sent from managed devices to the NM station. These traps allow
an administrator to discover device faults immediately.
The managed devices do not require the acknowledgement from the NM
station after sending traps.
6
1: SNMP
Description of features supported by SNMP(2)
Operation
Inform
GetBulk
Function
Informs are sent from managed devices to the NM station.
The managed devices require the acknowledgement from the NM station
after sending informs. If a managed device does not receive an
acknowledgement after sending an inform, it will resend the inform to the NM
station and generate alarm logs. Even if the NM station restarts, it can still
synchronize the informs sent during the restart process.
If the device does not receive an acknowledgement from the NM station after
sending an inform, it will store the inform in its memory. In this regard, using
informs may consume lots of system resources.
GetBulk allows an administrator to perform Get-next operation in batches. In a
large-scale network, GetBulk reduces the administrator's workload and
improves management efficiency.

Usage scenarios of different SNMP versions
Version
Usage Scenario
SNMPv1
This version is applicable to small-scale networks whose networking is simple and
security requirements are low or whose security and stability are good, such as campus
networks and small enterprise networks.
SNMPv2c
This version is applicable to medium and large-scale networks whose security
requirements are not strict or whose security is good (for example, VPNs) but whose
services are so busy that traffic congestion may occur.
Using informs can ensure that the messages sent from managed devices are received
by the NM station.
SNMPv3
This version is applicable to networks of various scales, especially the networks that
have strict requirements on security and can be managed only by authorized
administrators, such as the scenario where data between the NM station and managed
devices needs to be transmitted over a public network.

2: NTP
Introduction:

NTP(Network Time Protocol)

Aim: synchronizing clocks of all devices in a network. It keeps all the clocks
of these devices consistent, and enables devices to implement various
applications based on the uniform time.

NTP packets are encapsulated in UDP packets for transmission and the port
used by the NTP protocol is 123.
27
2: NTP-Application

Network management: Analysis on logs or debugging information collected from
different switches should be performed based on time.

Charging system: requires the clocks of all devices to be consistent.

Completing certain functions: For example, timing restart of all the switches in a
network requires the clocks of all the switches be consistent.

Several systems working together on the same complicate event: Systems
have to take the same clock for reference to ensure a proper sequence of
implementation.

Incremental backup between the backup server and clients: Clocks on the
backup server and clients should be synchronized.
28
2: NTP
Advantages :

Defining clock accuracy by means of stratum to synchronize the time of
network devices in a short time

Supporting access control and MD5 authentication

Transmitting packets in unicast, peer, multicast, or broadcast mode
29

How To Work
the client can be synchronized to the server but the server cannot be
synchronized to the client.
Peer Mode
The symmetric active end and symmetric passive end can be
synchronized with each other. the clock with a lower stratum is
synchronized to the one with a higher stratum.
Broadcast Mode
The server periodically sends clock synchronization packets to the
255.255.255.255. The client exchanging messages with the remote
server and then synchronize the local clock.
Multicast Mode
The server periodically sends clock synchronization packets to the
multicast address 224.0.1.1, The client exchanging messages with the
remote server and then synchronize the local clock.

3: HGMP-Introduction
The Huawei Group Management Protocol (HGMP) is developed to manage a group
of Ethernet switches. By running HGMP, you can appoint a switch as the
administrator in a cluster to perform integrated management and configurations
over other switches added to the cluster.
Aim: Simplifies management
Save IP addresses
42
3: HGMP Character
NDP
In HGMP, Neighbor Discovery Protocol
(NDP) packets are used to collect
information about the directly
connected neighbors, including the
device model, software version,
hardware version, connection
interface, member number, private IP
address used for communication
within a cluster, and hardware
platform.
43
NTDP
In HGMP, Network Topology
Discovery Protocol (NTDP) packets
are used to collect
information about topologies.
According to the neighbor
information in the NDP table, the
device sends and forwards
requests for topology collection,
and then collects entries in the
NDP table of each device in a
certain network segment.

The Link Layer Discovery Protocol (LLDP) is a Layer 2 discovery
protocol defined in the IEEE 802.1ab standard
The Layer 2 discovery protocol precisely discovers the interfaces on
Each device and obtains connection information between devices. In
addition, it displays the paths between clients, switches, routers,
application servers, and network servers. The Layer 2 information
helps you:
quickly know the device topology, detect configuration conflicts
between devices, and locate network faults.

5: Ping
Principle of the ping operation
Format of ICMP Echo Request and Echo Reply messages
The ping command is used to check network connectivity and host reach ability.
Ping tests IP reach ability and status of the link between the source and the destination by checking
whether the destination sends back an ICMP Echo Reply message and measuring the interval
between sending the ICMP Echo Request message and receiving the ICMP Echo Reply message.
70
5: Tracert
Tracert (Trace Route), is used to check the IP addresses and the number of
gateways between the source and the destination. Tracert is helpful in testing
network reach ability And locating the fault on the network.
The S9700 implements tracert based on ICMP. Tracert records the gateways that
the ICMP message passes along the path between a source host and a
destination. In this manner, you can check network connectivity and locate the
fault.
71

6: NQA-Introduction

NQA - Network Quality Analysis

NQA measures the performance of each protocol running on the network
and helps network operators collect network operation statistics, such as
the total HTTP delay, TCP connection delay, file transfer rate, FTP
connection delay, Domain Name System (DNS) resolution delay, and DNS
resolution error ratio. By collecting these statistics, network operators
provide users with network services of various grades.

NQA is an efficient tool for diagnosing and locating faults on a network.
75
6: NQA VS Ping
By sending an Internet Control Message Protocol
(ICMP) Echo-Request packet from the local and
expecting an ICMP Echo-Reply packet from the
specified destination, the Ping program can test
the round-trip time (RTT) of an ICMP packet.
In addition to testing the RRT of an ICMP
packet between the local and the
destination, NQA can detect whether
network services, such as TCP, UDP, FTP,
HTTP and the SNMP, are enabled and test
the response time of each service.
76
6: NQA-Between test instance & server
NQA test instance and NQA Client
NQA can be used to test many items. You must create a test instance
for each item and each of these test instances is a type of NQA test.
You need to create NQA test instances on NQA clients. Each test
instance has an administrator name and an operation tag as unique
identification.
NQA Server
In most types of tests, you need to configure only the NQA clients. In
TCP, UDP, and Jitter tests, however, you must configure the NQA server.
An NQA server processes the test packets received from the clients.
the NQA server responds to the test request packet received from the
client through the monitoring function.
77
6: NQA-How to work

In most types of tests, you need to configure only the NQA clients. In TCP,
UDP, and Jitter tests, however, you must configure the NQA server.

An NQA server processes the test packets received from the clients. the
NQA server responds to the test request packet received from the client

7: AAA-Introduction
Authentication: determines the users who can access the
network
Authorization: authorizes the users who can use certain
services
Accounting: records the usage of network resources.
Performing AAA for
access users
* On the S9700, AAA is mainly
used to authenticate and
authorize the users who log in to
the S9700 for system
configuration. does not support
accounting *
85
7: AAA-Authentication
The S9700 provides authentication schemes in the following modes:

Non-authentication: In this mode, the S9700 does not authenticate user validity
when users are trusted. This mode is not adopted in other scenarios.

Local authentication: In this mode, user information such as user names,
passwords, and other attributes is configured on theS9700. The S9700
authenticates users according to the information. In local authentication mode, the
processing speed is fast, but the capacity of information storage is restricted by
the hardware.

Remote authentication: In this mode, user information such as user names,
passwords, and other attributes is configured on an authentication server. The
S9700 functions as the client to communicate with the authentication server
through the RADIUS or HWTACACS protocol.
86
7: AAA-Authorization
The S9700 provides authorization schemes in the following modes :

Non-authorization: completely trusts users and directly authorizes them.

Local authorization: authorizes users according to the configured attributes of
local user accounts on the S9700.

Remote authorization: the S9700 functions as the client to communicate with the
authorization server through HWTACACS.

If-authenticated authorization: authorizes users after the users pass
authentication in local or remote authentication mode.
87
7: AAA-Accounting
The S9700 provides the following accounting modes:

None: Users are not charged.

RADIUS accounting: The S9700 sends the accounting packets to the RADIUS
server. Then the RADIUS server performs accounting.

HWTACACS accounting: The S9700 sends the accounting packets to the
HWTACACS server. Then the HWTACACS server performs accounting.

7: AAA-Radius Introduction
In remote authentication and remote authorization, the S9700 serves as
The RADIUS client and transfers information about authentication and
authorization of the user to the RADIUS server.
The RADIUS protocol defines the mode of transferring user information
between the RADIUS client and the RADIUS server. The messages
exchanged between the RADIUS client and the RADIUS server are
encrypted before being sent.

7: HWTACACS-Introduction
HWTACACS is a security protocol and an extension of TACACS defined in RFC1492. The process of
transmitting HWTACACS messages is similar to that of transmitting RADIUS messages. The
difference is that the HWTACACS server sends an authentication acknowledgement packet rather
than the user authority after the user passes authentication. The user authority is returned only after
the authorization process is complete. HWTACACS authorizes users using the command line.

8: RMON
RMON(Remote Network Monitoring),is a protocol to monitor the
Ethernet interface ,it is implemented based on the SNMP
There are two concepts involved in RMON, namely, the Network
Management Workstation (NM Station) and the agent. A RMON agent
collects statistics of various traffic in a network.
Compared with SNMP, RMON monitors remote network devices more
efficiently and actively. It provides an efficient solution to monitor the
running of sub-networks, which reduces the communication traffic
between the NM Station and the agent. Large-sized networks can thus
be managed in a simple and effective manner.
108
8: RMON
RMON allows multiple monitors. It collects data in the following ways:

Use a dedicated RMON Probe. This ensures that the NM Station can obtain
overall information on the RMON MIB.

Embed a RMON agent into a network device (a switch for example) to enable the
device to be of the RMON Probe capability. the NM Station collects only
information on four groups (alarm, event, history, and statistics) and not the
complete information on the RMON MIB.
*Currently, the S9700 implements the monitoring and statistics collection function
only on the Ethernet interfaces of network devices.*

For IPV6
142
10: Why IPV6
IPV4’s deficiencies:
1、IPV4 address space is deficient;
2、The routing table entry number maintained by backbone routers is too large;
3、It is not easy to configure automatically and re-addressing;
4、Can not solve the increasingly prominent security issues.
IPV6’s advantages:
1、Use 128 bit address structure which can provide sufficient address space;
2、Hierarchical network structure to improve routing efficiency;
3、IPV6 packet head is succinct, flexible, more efficiently and expansively;
4、Support auto configuration, plug-and-play;
5、Support end to end security;
6、Support mobile feature;
7、Support flow label feature which is more conducive to support QoS.

10: Management feature for IPV6
HUAWEI SX7 series switches support management feature for IPV6, such as:
No.

10: SX7 series support SNMP for IPV6
SNMP for IPV6 consists of the following functions:
Function
Description
Read SNMP packet
Read and dispose the SNMP packets based on IPV4 and IPV6 at
the same time. The two kind of packets work independently of
each others. So our switches can run at the all IPV6 environment or
IPV6 and IPV4 mix environment.
Send IPV6 based trap
Provide command line to configure NM host based on IPV6 to
make the trap can be sent to this NM host based on IPV6 protocol.
Track or record the
SNMP IPV6 packets
Do not provide additional command line to configure SNMP IPV6
packet track. The SNMP IPV6 and SNMP IPV4 use the same
command and the displays adjust the protocol automatically.
Command line for configuring the IPV6 trap
145
10: SX7 series support IPV6 MIB
Principle description:
HUAWEI IPV6 MIB is developed based on the RFC2465.
The IPv6 General group consists of 6 tables:
ipv6IfTable:
The IPv6 Interfaces table contains information on the entity’s IPv6 interfaces.
ipv6IfStatsTable:
This table contains information on the traffic statistics of the entity’s IPv6 interfaces. ipv6AddrPrefixTable:
The IPv6 Address Prefix table contains information on Address Prefixes that are associated with the entity’s
IPv6 interfaces.
ipv6AddrTable:
This table contains the addressing information relevant to the entity’s IPv6 interfaces.
ipv6RouteTable:
The IPv6 routing table contains an entry for each valid IPv6 unicast route that can be used for packet
forwarding determination.
ipv6NetToMediaTable:
The IPv6 address translation table contain the IPv6 Address to ‘physical’ address equivalencies.
146
10: SX7 series support IPV6 features
Other management features:
SX7 series support other management features for IPV6 such as SSH for IPV6, Ping6, Tracert6, FTP for IPV6,
TFTP for IPV6, Telnet for IPV6. All these features are realized according to the way for IPV4, the difference is
that feature for IPV6 is based on IPV6 protocol and the packet uses the IPV6 head.

Summary

SNMP(If the NM station and managed device are both Huawei products, follow
the procedure described in Enabling the SNMP Extended Error Code Function to
allow the device to send more types of error codes. This allows more specific error
identification and facilitates your fault location and rectification.)
