Administrative Interface

The AlliedTelesyn International AT-8116 Fast Ethernet switch

provides a cost-effective solution for Ethernet and Fast Ethernet

connectivity.With 16 dual-speed 10/100 ports,the AT-8116 switch

delivers the port density and performance required for a wide range

of bandwidth-intensive applications.The autosensing 10/100 ports

allow for compatibility with today’s network while providing a

growth path for the future.

The AT-8116 is a simple-to-use switch that provides versatile

conﬁguration options for the network.It can be used to link hubs to

maximize performance in existing shared media LANs,aggregate

trafﬁc from workgroup switches,and provide dedicated bandwidth

for demanding applications such as client/server and multimedia

applications.

Features

The AT-8116 has the following major features:

❑

16 dual-speed 10/100 TX ports autosensing

❑

Half/Full Duplex selectable on each port

❑

1.6Gbps High Performance Switch

❑

Full Wire Speed on All Ports

❑

Support for up to 8K MAC addresses

❑

Port-based VLANs with support for up to 16 VLANs

❑

IEEE 802.1d spanning tree

❑

Port Mirroring

❑

SNMP Management

❑

RMON

Administrative Interface

1-2

The AT-8116 contains a built-in SNMP agent running on the SNMP

Processor Board.This allows each unit to be managed from a

centralized management station via any SNMP-compliant NMS.

The SNMP agent software complies with the following standards:

❑

RFC1155-TheStructureofManagementInformation(SMI)for

TCP/IP Based Internets, May 1990

❑

RFC 1212 - The Management Information Base I (MIB I)

❑

RFC 1213 - The Management Information Base II (MIB II),

March 1991

❑

RFC 1284 - The Ethernet MIB

❑

RFC 1286 - The Bridge MIB

❑

RFC 1757 - The RMON MIB

❑

The UDP/IP stack implementation conforms to:

— RFC 1122-Requirements for Internet host-

communication layers.

— RFC 1123-Requirements for Internet host-applications

and support.

The AT-8116 also supports two private MIBs:switch.mib and

gswitch.mib.

The SNMP agent utilizesTFTP (RFC 1350),UDP/IP (RFC 768,RFC950,

RFC1071 and RFC791) as OSI layers 3 and 4 protocols,ICMP (RFC792)

and ARP (RFC826) to complete the UDP/IP protocol suite.

The UDP/IP stack implementation conforms to:RFC 1122-

Requirements for Internet hosts - communication layers.RFC

1123-Requirements for Internet hosts - application and support.

Network Management Systems

Network management functions greatly assist in monitoring and

controlling your network.The AT-8116 can be monitored and

controlled through a generic SNMP-based NMS.The connection to

the AT-8116 may be achieved through Ethernet.

The AT-8116 can also be conﬁgured and managed through the

Command Line Interface.The process is described in detail in the

following pages.

Accessing the SNMP Agent

This section describes how to use the console services to conﬁgure

and manage the AT-8116.

Software

Requirements

If you are using a workstation,use theVT100 terminal emulation

software appropriate for your workstation.

If you are using a PC to emulate a VT100 terminal,you can use the

following software:

❑

In a DOS environment:

— MS-DOS 3.30 or later

— PROCOMM PLUS for DOS

❑

In a Windows 3.1 environment:

— Microsoft Windows 3.1 or later

— Windows Terminal or PROCOMM PLUS for Windows

❑

In Windows 95 or NT

— Hyperterminal

Note

Because of their compatibility and reliability, the software

combinationlistedabovearerecommended.Otherapplicationsmay

also provide satisfactory results.

VT100 Terminal Settings

Use the following settings when connecting theVT100 terminal or

terminal emulator to the AT-8116.

❑

Communications Setup

— 9600 (baud)

— No Parity

— 8 Data Bits, 1 Stop Bit

— No Local Echo

— VT100 Mode

❑

Terminate the setup session by pressing Ctrl-C.

Testing the Installation

After you have completed the installation,use the CLI ping

command to test for connectivity.See Chapter 15,“

Using an SNMP

Manager

”.

The ping command sends an echo request to the host speciﬁed in

the command line.For example,to test connectivity from the switch

to a workstation with an IP address of 192.1.1.126,use the following

command:

SYS_console>ping 192.1.1.126 2

Use CTRL-C or ping-stop to stop the ping

process

SYS_console>192.1.1.126 Alive. echo reply: id

4643, seq 1, echo-data-len 0

191.1.1.126 Alive. echo reply: id 4643, seq 2,

echo-data-len 0

PING process stopped - statistics:

ICMP echo requests: 2

ICMP echo responses: 2

PING process - press <CR> for prompt

Five telnet sessions may be active at any given time.This means that

after the ﬁfth telnet session is established,all other telnet

connections will be refused until one of the current sessions is

closed.
