About this book
10 Overview for the Avaya G250 and Avaya G350 Media Gateways
Chapter 1: Introduction
The Avaya CM Branch Gateways (Avaya G250 and Avaya G350 Media Gateways) form part of
Avaya’s solution for extending communication capabilities from the headquarters of an
organization to all collaborative branch locations. Avaya CM Branch Gateways help you provide
the same high quality services to all organization members, regardless of their location.
The Branch Gateways are high-performance converged telephony and networking devices that
are located in small branch locations, providing all infrastructure needs in one box — telephone
exchange and data networking. The Branch Gateways each feature a VoIP engine, WAN router,
and Power over Ethernet LAN connectivity. The G350 provides full support for legacy IP, DCP,
and analog telephones. The G250 supports legacy IP and analog telephones. In addition, the
G250-DCP model supports DCP telephones.
The G350 is designed for use in an eight to 72 user environment, aimed at branch offices with
16 to 40 stations. The G250 is designed for use in a two to 12 user environment, aimed at small
branch offices with two to eight stations.
Telephone services on a Branch Gateway are controlled by a Media Gateway Controller (MGC).
You can use an Avaya S8XXX Server running Communication Manager (CM) call processing
software as an MGC. The gateway integrates seamlessly with Avaya S8700, S8710, S8720,
S8730, S8500, S8400, and S8300 Servers to provide the same top quality telephony services
to the small branch office as to the headquarters of the organization.
Note:
Note:
The S8700 Server cannot be upgraded to CM 5.0.
The Branch Gateways can subtend to an MGC located at the headquarters or the MGC can be
installed locally. The Branch Gateways can optionally house an internal Avaya S8300 server for
Enhanced Local Survivability (ELS), providing full MGC functionality in the event that the
connection with the primary MGC is lost, or as the primary MGC for standalone deployment.
When the primary MGC is located at a remote location, the Branch Gateway features Standard
Local Survivability (SLS). SLS provides partial backup MGC functionality in the event that the
connection with the primary MGC is lost.
In addition to advanced and comprehensive telephony services, the Branch Gateways provide
full data networking services, precluding the need for a WAN router or LAN switch.

Introduction
Avaya G350 Media Gateway Overview
The G350 is a modular device, adaptable to support different combinations of endpoint devices.
Pluggable media modules provide interfaces for different types of telephones and trunks. A
combination is selected to suit the needs of the branch. A LAN media module with PoE
standard compliant Ethernet ports provides support for IP telephones as well as all other types
of data devices. A range of telephony modules provides full support for legacy equipment such
as analog and digital telephones.
Avaya G250 Media Gateway Overview
The G250 supports the connection of PCs, LAN switches, IP telephones, analog telephones,
and trunks, via fixed analog and PoE ports on the chassis. A media module slot supports either
of two WAN media modules, for connection to a WAN. There are several models of the G250,
with various port combinations for support of analog, BRI, or T1/E1 trunks or DCP telephones,
as described below.
The G250 is available in the following models:
●
Analog model (G250-Analog). The G250-Analog includes four analog trunk ports, two
analog line ports, a Fast Ethernet WAN port, and eight PoE LAN ports.
●
BRI model (G250-BRI). The G250-BRI includes two ISDN BRI trunk ports, one analog
trunk port, two analog line ports, a Fast Ethernet WAN port, and eight PoE LAN ports.
●
DCP model (G250-DCP). The G250-DCP provides twelve DCP (Digital Communications
Protocol) ports, as well as four analog trunk ports, two analog line ports, a Fast Ethernet
WAN port, and two LAN ports.
●
DS1 model (G250-DS1). The G250-DS1 provides a T1/E1 and a PRI trunk port, enabling
support of fractional T1/E1 and PRI. The G250-DS1 also includes one analog trunk port,
two analog line ports, a Fast Ethernet WAN port, and eight PoE LAN ports.

Chapter 3: Summary of services
The Branch Gateway (G250 or G350) offers various services, which are described in Media
gateway services on page 37, LAN services on page 45, and WAN services on page 47.
Media gateway services
The Avaya G250 and Avaya G350 Media Gateways provide a telephone exchange service,
supporting the connection of various types of telephones and outside telephone lines.
Telephones and lines are connected to the G250/G350 via ports and media modules on the
chassis. Different media modules provide access ports for different types of telephones and
lines.
Telephony services are controlled by a media gateway controller (MGC) running Avaya
Communication Manager (CM) call processing software. You can use the Avaya CM to
configure many advanced telephone exchange functions. For more information, see the
Administrator’s Guide for Avaya Communication Manager, 555-233-506.
This section describes the services the G250/G350 provides as a media gateway. All services
are supported by both the G250 and the G350 except where otherwise specified.
Voice over IP (VoIP)
The Avaya G250 and Avaya G350 Media Gateways feature a VoIP engine that provides voice
services over IP data networks. The G250/G350 allows you to use many types of telephones
and trunks that do not directly support VoIP. The G250/G350 translates voice and signalling
data between VoIP and the system used by the telephones and trunks, as follows: Avaya media
modules convert the voice path of traditional circuits such as analog trunk, T1/E1, and DCP to a
TDM bus inside the G250/G350. The VoIP engine then converts the voice path from the TDM
bus to a compressed or uncompressed and packetized VoIP on an Ethernet connection.
Both the G250 and the G350 provide VoIP services over the LAN and WAN. The G350 supports
the G.711 codec for up to 32 concurrent calls and the G.729 codec for up to 16 concurrent calls.
The G250-Analog and G250-BRI support both the G.711 and the G.729 codec, for a total of 10
concurrent calls. The G250-DCP and G250-DS1 support both the G.711 and the G.729 codec,
for a total of 16 concurrent calls.

Media Gateway Controllers
A Media Gateway Controller (MGC) controls telephone services on a media gateway. An MGC
may be internal to the media gateway or external to the media gateway. An Internal Call
Controller (ICC) is an internal MGC. An External Call Controller (ECC) is an external MGC that
communicates with the G250/G350 over the network.
An Avaya S8XXX server managed with Avaya Communication Manager (CM) software acts as
an MGC for the Avaya G250 or Avaya G350 Media Gateway.

Configuring G250/G350 options
The G250/G350 provides the following configuration options to help you ensure continuous
telephone services:
●
You can configure the G250/G350 to use up to four MGCs. If the MGC is an S8700,
S8710, S8720, or S8730, the first server on the list will normally be the primary C-LAN
board connected to the S8xxx server. If the MGC is an S8400 or S8500, the first server on
the list will be either the primary C-LAN board connected to the S8xxx server or an
Ethernet port on the server that has been enabled for processor Ethernet connections. If
the MGC is an S8300, the first server on the list will be the IP address of the S8300. The
remaining servers will be alternate C-LAN boards connected to the S8xxx server (S8400,
S8500, or S8700-series servers), an S8300 configured as an LSP, or the port enabled as
the Ethernet processor port on an S8500 configured as an LSP.
●
Using the connection preserving migration feature, you can configure the G250/G350 to
preserve the bearer paths of stable calls in the event that the G250/G350 migrates to
another MGC (including an LSP), including migration back from an LSP to the primary
MGC. A call for which the talk path between parties in the call has been established is
considered stable. A call consisting of a user listening to announcements or music is not
Issue 5 June 2008
41
Summary of services
considered stable and is not preserved. Any change of state in the call prevents the call
from being preserved. For example, putting a call on hold during MGC migration will cause
the call to be dropped. Special features, such as conference and transfer, are not available
on preserved calls. Connection preserving migration preserves all types of bearer
connects except BRI. PRI trunk connections are preserved.
●
You can configure Standard Local Survivability (SLS) to enable a local G250/G350 to
provide a degree of MGC functionality when no link is available to an external MGC. SLS
is configured on a system-wide basis using the Provisioning and Installation Manager
(PIM). Alternatively, SLS can be configured from the individual G250/G350 itself using the
CLI. SLS is supported as follows in the various Branch Gateway models:
- G350 with C/S (hardware vintage) 3.0 and up: SLS supported for all analog interfaces,
ISDN BRI/PRI trunk interfaces, non-ISDN digital DS1 trunk interfaces, IP phones, IP
Softphone, and DCP phones.
- G250-Analog: SLS supported for all analog interfaces, IP phones, and IP Softphone.
- G250-BRI: SLS supported for all analog interfaces, ISDN BRI trunk interfaces, IP
phones, and IP Softphone.
- G250-DCP: SLS supported for all analog and DCP interfaces, IP phones, IP
Softphone, and DCP phone.
- G250-DS1: SLS supported for all analog interfaces, ISDN PRI trunk interfaces,
non-ISDN digital DS1 trunk interfaces, IP phones, and IP Softphone.
Note:
●
You can configure Enhanced Local Survivability (ELS) by installing an S8300 in the G250/
G350 as a Local Survivable Processor (LSP). In this configuration, the S8300 is not the
primary MGC but takes over to provide continuous telephone service if all external MGCs
become unavailable. Calls in progress continue without interruption when the S8300 takes
over.
●
You can configure the dialer interface to connect to the G250/G350’s primary MGC via a
serial modem in the event that the connection between the G250/G350 and the MGC is
lost.
●
You can configure the Avaya CM to support the auto fallback feature, which enables a
G250/G350 being serviced by an LSP to return to its primary MGC automatically when the
connection is restored between the G250/G350 and the MGC. When the G250/G350 is
being served by its LSP, it automatically attempts to register with its MGC at periodic
intervals. The MGC can deny registration in cases in which it is overwhelmed with call
processing, or in other configurable circumstances. By migrating the G250/G350 to the
MGC automatically, a fragmented network can be unified more quickly, without the need
for human intervention.
Note:
Auto fallback does not include survivability. Therefore, there is a short period
during registration with the MGC during which calls are dropped and service is
not available. This problem can be minimized using the connection preserving
migration feature.

Media gateway services
●
The G250/G350 features a dynamic trap manager, which enables you to ensure that the
G250/G350 sends traps directly to the currently active MGC. If the MGC fails, the dynamic
trap manager ensures that traps are sent to the backup MGC.
MGC management
The MGC is managed by the Avaya Communication Manager (CM). The G250/G350 supports
Avaya Communication Manager (CM) release 5.0 and is backwards compatible with release 2.0
and above.

LAN services
!
WARNING:
WARNING:
Do not enable ETR on ports used for DID.
An outside telephone exchange can be connected to the trunk port, and an analog telephone
can be connected to the line port. All calls are then directed by the analog relay between the
outside line and the analog telephone. A current-loop detection circuit prevents ongoing calls
from being disconnected when normal functioning resumes. It is recommended that ETR not be
enabled for line ports that are administered for use with analog DID trunks.
Contact closure
The contact closure feature is a controllable relay providing dry contacts for various
applications. To implement the contact closure feature, connect an Avaya Partner Contact
Closure Adjunct box to the CCA port on the G250/G350 chassis. The adjunct box provides two
contact closures that can be operated in either a “normally closed” or “normally open” state. The
contact closures can control devices such as devices that automatically lock or unlock doors or
voice recording units. The CCA port can be configured so that the connected devices can be
controlled by an end device, such as a telephone. For example, a user can unlock a door by
keying a sequence into a telephone keypad.
Fax, modem, TTY over IP
The G250/G350 supports fax, modem, and TTY over IP.
LAN services
You can use both the Avaya G250 and Avaya G350 Media Gateways as a LAN switch. You can
also integrate the G250/G350 into an existing LAN.
Physical media
The G350 provides LAN services through the following Ethernet ports for the connection of local
data devices:
●
Switched LAN ports. Configurable switched Ethernet ports on the MM314 media module
(see MM314 LAN media module on page 32) and the MM316 media module (see MM316
LAN media module on page 33). The switched Ethernet ports support HP auto-MDIX,
which automatically detects and corrects the polarity of crossed cables. This results in
simplified LAN installation and maintenance.
Issue 5 June 2008
45
Summary of services
●
Fixed LAN port. The fixed LAN port on the chassis, connected to the internal LAN switch.
The fixed LAN port supports HP auto-MDIX, which automatically detects and corrects the
polarity of crossed cables. This results in simplified LAN installation and maintenance.
The G250 provides LAN services through eight fixed ETH LAN PoE ports on the chassis.
Note:
The G250-DCP only has two fixed ETH LAN ports. These ports do not support PoE.
Note:
Power over Ethernet (PoE)
In the G350, the MM314 and MM316 media modules’ ports provide power to data devices over
the Ethernet connection (PoE). The ports support the connection of IP phones and wireless
access points, which you may want to power through the G350.
In the G250, PoE service is provided by eight fixed ETH LAN PoE ports on the chassis.
Note:
The G250-DCP does not provide PoE service.
Note:
The inline PoE feature enables you to power data devices through the G250/G350. Power is
distributed between the PoE ports, according to configured priorities. You configure the power
priority on each port. Distribution is calculated from the actual power consumption.
An automatic discovery system detects when powered devices are connected to and removed
from the PoE ports. Automatic load detection:
●
Tests whether the device connected to the port requires remote powering
●
Controls the power injection to the wires
VLANs
In the G350, you can configure VLANs on the fixed LAN port and on the MM314 and MM316
ports. In the G250, you can configure VLANs on all Ethernet ports except the WAN ETH port.
Both the G250 and the G350 support up to eight VLANs. The following VLAN features are
supported:
●
VLAN port grouping. Port VLANs can be used to group LAN ports into logical groups.
●
Ingress VLAN Security. You configure a list of ingress VLANs on each port. Any packets
tagged with an unlisted VLAN are dropped when received on the port.
●
Class of Service (CoS) tagging. Packets are tagged with VLANs per CoS.
●
Inter-VLAN routing. You can configure specific VLANs to permit access to the WAN while
others can be configured to deny access to the WAN.

WAN services
Rapid Spanning Tree Protocol (RSTP)
The IEEE 802.1D (STP) and IEEE 802.1w (RSTP) Spanning Tree Protocols are supported on
the MM314 and MM316 switched LAN ports.
Note:
Note:
STP is not supported in the G250.
Port mirroring
Both the G250 and the G350 support network traffic monitoring by port mirroring. You can
configure port mirroring on any LAN port. You implement port mirroring by connecting an
external traffic probe device to one of the LAN ports. The probe device monitors traffic that is
sent and received through other ports by copying the packets and sending them to the monitor
port.
Note:
Note:
You cannot configure port mirroring on the G350 fixed LAN port or the G250/
G350 WAN Fast Ethernet ports.
Port redundancy
You can configure port redundancy on the G350. Port redundancy allows you to provide both a
primary link and a backup link to an important resource.Port redundancy is supported between
any two PoE ports on the MM314 or the MM316 media modules.
WAN services
The G250/G350 has an internal router and provides direct access to outside WAN lines. You
can use the G250/G350 as the endpoint device for a WAN line. You can also use the G250/
G350 as the router for a WAN line with an external endpoint device.
Issue 5 June 2008
47
Summary of services
Physical media
To use the G250/G350 as the endpoint device for a WAN, install a WAN media module and
connect the WAN line to a port on the media module. When you connect a WAN line to a media
module, the G250/G350 serves as the router for the WAN line.
You can also use the fixed ETH WAN Fast Ethernet port as a WAN endpoint by configuring the
port’s interface for PPPoE encapsulation (ADSL modem) or Ethernet-DHCP/static IP (cable
modem).
To use the G250/G350 as a router, connect the external endpoint device to the fixed WAN port
on the G250/G350 front panel using a standard network cable. See G250 physical
description on page 15 and G350 physical description on page 19 for the location of the WAN
port on the G250 and G350 front panels.
You can also use the fixed WAN port to connect a computer or other endpoint data device to the
G250/G350.

WAN features
The G350 supports the following WAN features. The G250 also supports these features, except
where otherwise noted.
●
Traffic shaping. The traffic shaping function estimates the parameters of the incoming
traffic and takes action if it measures traffic exceeding agreed parameters. The action
could be to drop the packets or mark them as being high drop priority.
●
PPP over channeled and fractional E1/T1. The G250/G350 has the ability to map several
PPP sessions to a single E1/T1 interface.
Note:
The G250 only supports fractional E1/T1.
Note:
●
PPP over Universal Serial Port
●
PPPoE
●
Unframed E1 for enabling full 2.048 Mbps bandwidth usage
●
Point-to-Point Frame Relay encapsulation over channelized/fractional/unframed E1/T1
ports or over a Universal Serial Port interface
●
Frame Relay LMI types supported: ANSI (Annex D), ITU-T:Q-933 (Annex A0), LMI-Rev1,
and No LMI
●
Backup functionality supported between any type of Serial Layer 2 interface
●
Dynamic Call Admission Control (CAC) for Fast Ethernet, Serial, and GRE tunnel
interfaces. Dynamic CAC provides enhanced control over WAN bandwidth. When
Dynamic CAC is enabled on an interface, the G250/G350 informs the MGC of the actual
bandwidth of the interface and tells the MGC to block calls when the bandwidth is
exhausted.
●
Quality of Service (QoS). The G250/G350 uses Weighted Fair VoIP Queuing (WFVQ) as
the default queuing mode for WAN interfaces. WFVQ combines weighted fair queuing
(WFQ) for data streams and priority VoIP queuing to provide the real-time response time
that is required for VoIP. The G250/G350 also supports the VoIP Queue and Priority
Queue legacy queuing methods.
●
Weighted Random Early Detection (WRED). The G250/G350 uses WRED on its ingress
and egress queues to improve the performance of the network when overloaded. The
purpose of WRED is to indicate to transmitting hosts to reduce their transmission speed
when the ingress G350 queues are congested.
●
Policy. Each interface on the G250/G350 can have four active policy lists:
- Ingress Access Control List
- Ingress QoS List
- Egress Access Control List
Issue 5 June 2008
49
Summary of services
- Egress QoS List
Access control lists define which packets should be forwarded or denied access to the
network. QoS lists change the DSCP and 802.1p priority of routed packets according to
the packet characteristics.
●
Policy-based routing. The G250/G350 features policy-based routing, which uses a policy
list structure to implement a routing scheme based on traffic source, destination, type, and
other characteristics. You can use policy-based routing lists (PBR lists) to determine the
routing of packets that match the rules defined in the list. Common applications include
separate routing for voice and data traffic, routing traffic originating from different sets of
users through different Internet connections (Internet Service Providers), and defining
backup routes for defined classes of traffic.
●
RTP Header Compression. The G250/G350 saves up to 60% of the bandwidth necessary
using RTP compression. It also enhances the efficiency of voice transmission over the
network by compressing the headers of Real Time Protocol (RTP) packets, thereby
minimizing the overhead and the delays involved in RTP implementation.
●
TCP Header Compression. The G250/G350 uses Transmission Control Protocol (TCP)
header compression to reduce the amount of bandwidth needed for non-voice data. TCP
header compression can be applied either as part of RTP Header Compression via IPCH,
or using the Van Jacobson method defined in RFC 1144.
●
Inter-Gateway Alternate Routing (IGAR). The G250/G350 uses IGAR as a means to use
the PSTN as an alternative to the WAN interface under certain definable conditions. In
providing an alternate routing mechanism, IGAR preserves the internal makeup of the call
so that the call can be successfully terminated to its original internal destination.
Routing features
Both the G250 and the G350 have an internal router. You can configure the following routing
features on the router:
●
Interfaces
●
Routing table
●
VPN
●
GRE tunneling
●
DHCP and BOOTP relay

For information about Avaya G250/G350 Manager, see the G250/G350/G450 Manager User
Guide, 14-300166.
Avaya Integrated Management
Avaya Integrated Management offers a comprehensive set of web-based network and system
management solutions that support Avaya converged voice solutions. You can use Avaya
Integrated Management to monitor SNMP traps on the G250/G350. You can also use Avaya
Integrated Management to access Avaya G250/G350 Manager.
Avaya QoS Manager
You can use Avaya QoS Manager to configure G250/G350 QoS policy capabilities. You can
access Avaya QoS Manager through Avaya Integrated Management software.
Management access security features
The G250/G350 features the following management security mechanisms:
●
A basic authentication mechanism in which users are assigned passwords and privilege
levels
●
Support for user authentication provided by an external RADIUS server
●
SNMPv3 user authentication
●
Secure data transfer via SSH and SCP with user authentication
54 Overview for the Avaya G250 and Avaya G350 Media Gateways
Network security features
●
ASG authentication for remote service logins. ASG is a challenge-response authentication
method that is more secure than password authentication and does not require a static
password.
Network security features
The Avaya G250/G350 Media Gateway provides the following network security features:
●
Private secure connections can be configured between the G250/G350 and a remote peer,
using VPN (Virtual Private Network). VPN at the IP level is deployed using a
standards-based set of protocols defined by the IETF called IPSec. IPSec provides
privacy, integrity, and authenticity to information transferred across IP networks.
●
Access to the G250/G350’s LAN ports is authenticated using the 802.1x protocol. On the
G350, you can enable 802.1x on the MM314 and MM316 media modules’ 10/100 Ethernet
ports. On the G250, you can enable 802.1x on the eight Ethernet LAN PoE ports located
on the G250’s front panel. The 802.1x protocol standard is extended to support an optional
mode for authenticating multiple supplicants.
●
Protection against DoS (Denial of Service) attacks via:
- MSS notifications. The G250/G350 identifies predefined or custom-defined traffic
patterns as suspected DoS attacks and generates SNMP notifications, referred to as
Managed Security Services (MSS) notifications. MSS notifications are intercepted
and, if certain conditions are met, may be forwarded to the Avaya Security Operations
Center (SOC) as INADS alarms. The SOC is an Avaya service group that handles
DoS alerts, responding as necessary to any DoS attack or related security issue.
- SYN cookies, which protect against a well-known TCP/IP attack in which a malicious
attacker targets a vulnerable device and effectively prevents it from establishing new
TCP connections.
Alarms and troubleshooting features
The Avaya G250 and Avaya G350 Media Gateways have extensive features for error detection,
alarms, and troubleshooting. Detailed diagnostic information and troubleshooting are provided
by software-based solutions accessible by laptops in the field or remotely from an
administrator’s computer. Administration for the Avaya G250 and Avaya G350 Media
Gateways, 03-300436, provides a comprehensive guide to configuring and using these
solutions.

Management, Security, Alarms and Troubleshooting
Front panel LEDs
LEDs on the front panel of the G250 and G350 and their media modules give a quick overall
understanding of the health of the system and subsystems. When alarms or problems occur,
LEDs indicate that a technician’s attention is needed.
Automatic error detection
During normal operations, software or firmware automatically detects and attempts to fix or
circumvent error conditions. Errors are detected in two ways:
●
Firmware on a system component during ongoing operations
●
A “periodic test” or a “scheduled test” started by software
A technician can run more comprehensive tests on demand.
SNMP
The G250/G350 reports alarms using SNMP traps. The G350 fully supports SNMP versions
SNMPv1, SNMPv2c, and SNMPv3. The G250 supports SNMPv3 for sending SNMPv1,
SNMPv2c, and SNMPv3 traps, but does not support the SNMPv1 trap mechanism.
Packet sniffing
The G250/G350 features packet sniffing. All packets, including non-Ethernet packets, that pass
through the G250/G350, are recorded. The recorded packets are stored in a file that can be
uploaded either to the S8xxx server or to a PC and read by Ethereal for troubleshooting
purposes.
56 Overview for the Avaya G250 and Avaya G350 Media Gateways
Alarms and troubleshooting features
VoIP debugging using RTP-MIB
The G250/G350 includes the RTP-MIB feature for debugging QoS-related problems across the
VoIP network without any dedicated hardware. During each RTP stream, counters representing
various QoS metrics increment whenever configured thresholds for the metrics are exceeded. A
limited history of the QoS metric statistics is stored on the G250/G350 for active and terminated
RTP streams. Statistics can be displayed via the G250/G350 CLI. In addition, the G250/G350
can be configured to send SNMP traps to the SNMP trap manager on the S8xxx server at the
termination of each RTP stream that has QoS problems. The traps are converted to syslog
messages and stored for viewing in the messages file on the S8xxx server hard disk.
Object tracking
The G250/G350 includes object tracking. The purpose of object tracking is to track the state
(up/down) of remote devices using keepalive probes, and notify registered applications when
the state changes. Object tracking is utilized by applications such as VPN to track remote
devices and take certain steps when the state of a remote device changes.
Converged Network Analyzer (CNA) test plug
CNA test plugs are a component of CNA, a distributed system tool for real-time network
monitoring that detects and diagnoses converged network-related issues. CNA is deployed in the
G250/G350 to identify any network conditions or impairments that can degrade the user
experience for IP telephony and to monitor overall network performance. Test plugs in media
gateways provide the ability to measure end-to-end service to the edge of the PSTN, or at points
where codec changes are required for interworking between high (LAN) and low (WAN) speed
links.
Link Layer Discovery Protocol (LLDP)
LLDP simplifies network troubleshooting and enhances the ability of network management tools
to discover and maintain accurate network topologies in multi-vendor environments. LLDP
defines a set of advertisement messages (TLVs), a protocol for transmitting the TLVs, and a
method for storing the information contained in the received TLVs. This allows stations attached
to a LAN to advertise information about the system and about the station’s point of attachment
to the LAN to other stations attached to the same LAN. These can be reported to the
management station via SNMP MIBs.
On the G250, LLDP is supported on all the Ethernet LAN ports on the chassis.
On the G350, LLDP is supported on the Ethernet LAN ports located on the MM314 and MM316
media modules.
