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

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.
For details concerning using the SNMP agent,see Chapter 15,

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.
