21.1.2 Wha t Yo u Ne e d To Kno w
The following terms and concepts may help as you read this chapter.
Ale rts a nd Log s
An alert is a type of log that warrants more serious attention. They include system errors, attacks (access
control) and attempted access to blocked web sites. Some categories such as System Erro rs consist of
both logs and alerts. You may differentiate them by their color in the View Lo g screen. Alerts display in
red and logs display in black.
Syslo g O ve rvie w
The syslog protocol allows devices to send event notification messages across an IP network to syslog
servers that collect the event messages. A syslog-enabled device can generate a syslog message and
send it to a syslog server.
Syslog is defined in RFC 3164. The RFC defines the packet format, content and system log related
information of syslog messages. Each syslog message has a facility and severity level. The syslog facility
identifies a file in the syslog server. Refer to the documentation of your syslog program for details. The
following table describes the syslog severity levels.

23.1 O ve rvie w
Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address (IP address) to
a physical machine address, also known as a Media Access Control or MAC address, on the local area
network.
An IP (version 4) address is 32 bits long. In an Ethernet LAN, MAC addresses are 48 bits long. The ARP
Table maintains an association between each MAC address and its corresponding IP address.
23.1.1 Ho w A RP Wo rks
When an incoming packet destined for a host device on a local area network arrives at the device, the
device's ARP program looks in the ARP Table and, if it finds the address, sends it to the device.
C HAPTER 23
ARP Ta b le
If no entry is found for the IP address, ARP broadcasts the request to all the devices on the LAN. The
device fills in its own MAC and IP address in the sender address fields, and puts the known IP address of
the target in the target IP address field. In addition, the device puts all ones in the target MAC field
(FF.FF.FF.FF.FF.FF is the Ethernet broadcast address). The replying device (which is either the IP address of
the device being sought or the router that knows the way) replaces the broadcast address with the
target's MAC address, swaps the sender and target pairs, and unicasts the answer directly back to the
requesting machine. ARP updates the ARP Table for future reference and then sends the packet to the
MAC address that replied.

Trellis Coding This displays whether or not the port is using Trellis coding for traffic it is sending and receiving.

Transmit Power This is the upstream and downstream far end actual aggregate transmit power (in dBm).
These are the rates at which the port is sending and receiving the payload data without
transport layer protocol headers and traffic.
Trellis coding helps to reduce the noise in ADSL transmissions. Trellis may reduce throughput but
it makes the connection more stable.
SNR is the ratio between the received signal power and the received noise power. The signalto-noise ratio margin is the maximum that the received noise power could increase with the
system still being able to meet its transmission targets.
determines the size of a single block of data to be interleaved (assembled) and then
transmitted. Interleave delay is used when transmission error correction (Reed- Solomon) is
necessary due to a less than ideal telephone line. The bigger the delay, the bigger the data
block size, allowing better error correction to be performed.
Upstream is how much power the port is using to transmit to the service provider. Downstream is
how much port the service provider is using to transmit to the port.
Receive Power Upstream is how much power the service provider is receiving from the port. Downstream is
how much power the port is receiving from the service provider.
Actual INP Sudden spikes in the line’s level of external noise (impulse noise) can cause errors and result in
lost packets. This could especially impact the quality of multimedia traffic such as voice or
video. Impulse noise protection (INP) provides a buffer to allow for correction of errors caused
by error correction to deal with this. The number of DMT (Discrete Multi-Tone) symbols shows the
level of impulse noise protection for the upstream and downstream traffic. A higher symbol
value provides higher error correction capability, but it causes overhead and higher delay
which may increase error rates in received multimedia data.
Total Attenuation This is the upstream and downstream line attenuation, measured in decibels (dB). This
attenuation is the difference between the power transmitted at the near-end and the power
received at the far-end. Attenuation is affected by the channel characteristics (wire gauge,
quality, condition and length of the physical line).

30.1 O ve rvie w
This chapter explains how to configure the SNMP settings on the XMG.
30.2 The SNMP Sc re e n
Simple Network Management Protocol is a protocol used for exchanging management information
between network devices. Your XMG supports SNMP agent functionality, which allows a manager
station to manage and monitor the XMG through the network. The XMG supports SNMP version one
(SNMPv1) and version two (SNMPv2c). The next figure illustrates an SNMP management operation.

SNMP
An SNMP managed network consists of two main types of component: agents and a manager.
An agent is a management software module that resides in a managed device (the XMG). An agent
translates the local management information from the managed device into a form compatible with
SNMP. The manager is the console through which network administrators perform network management
functions. It executes applications that control and monitor managed devices.
The managed devices contain object variables/managed objects that define each piece of
information to be collected about a device. Examples of variables include such as number of packets
received, node port status etc. A Management Information Base (MIB) is a collection of managed
objects. SNMP allows a manager and agents to communicate for the purpose of accessing these
objects.

Chapter 30 SNMP
SNMP itself is a simple request/response protocol based on the manager/agent model. The manager
issues a request and the agent returns responses using the following protocol operations:
• Get - Allows the manager to retrieve an object variable from the agent.
• GetNext - Allows the manager to retrieve the next object variable from a table or list within an agent.
In SNMPv1, when a manager wants to retrieve all elements of a table from an agent, it initiates a Get
operation, followed by a series of GetNext operations.
• Set - Allows the manager to set values for object variables within an agent.
• Trap - Used by the agent to inform the manager of some events.

You can select a specific date in a particular month or a specific day of a specific week in a
particular month. The Hour field uses the 24 hour format. Here are a couple of examples:
Daylight Saving Time starts in most parts of the United States on the second Sunday of March.
Each time zone in the United States starts using Daylight Saving Time at 2 A.M. local time. So in
the United States, set the day to Se cond , Sunda y, the month to Ma rc h and the time to 2 in the
Hour field.
Daylight Saving Time starts in the European Union on the last Sunday of March. All of the time
zones in the European Union start using Daylight Saving Time at the same moment (1 A.M.
GMT or UTC). So in the European Union you would set the day to La st, Sunda y and the month
to Ma rc h. The time you select depends on your time zone. In Germany for instance, you
would select 2 in the Ho ur field because Germany's time zone is one hour ahead of GMT or
UTC (GMT+1).
