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 -The Structure ofManagement Information (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 utilizes TFTP (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.

Testin g th e In stallation  
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 Commands  
If the host does not respond, only statistics are printed. Failure to get  
an echo response from a host may be due to:  
A bad physical connection  
A non-existent or inactive host  
Network Unreachable: no corresponding entry in the routing  
table  
Destination Unreachable: the default gateway failed to route  
the datagram  
Outdated ARP table information - flush the ARP table with the  
del-arp-entry command  
If there is an active ping process due to a previouslong”ping  
command and you try to start a new ping, the command fails and an  
error message is displayed.  
For example, start an endless ping to an unreachable host. No  
response will be received. Now try to ping an existing host.The  
second ping will fail because the first one is still active.The solution is  
to use the ping-stop command to stop the first active ping process.

SNMP Com m an ds  
This chapter contains a description of the commands available under  
the CLI to set and display the SNMP Agent IP and SNMP parameters  
and databases.Type <SNMP> to view SNMP related commands.  
SNMP Com m un ity Strin g Com m an ds  
SNMP Community strings authenticate access to the MIB  
(Management Information Base). Community strings function as  
passwords”embedded in every SNMP packet.The community string  
must match one of the two community strings configured in the  
switch for the message to be processed.There are two community  
strings, one for each of the following types of accesses:  
read - mode gives read access to all the objects in the MIB, but  
does not allow write access  
write - mode gives read and write access to all objects in the  
MIB  
get-comm  
get-comm {read|write|*}  
This command displays the SNMP community string for a given  
access mode ( read or write ). If the access mode is specified as *,  
both the read and the write community strings are displayed.  
SYS_console>get-comm *  
Current read community is: < public >  
Current write community is: < private >

SNMP Commands  
set-comm  
set-comm {read|write} <community-string>  
This command lets you specify the SNMP community string for each  
of the two access modes:read and write.  
SYS_console>set-comm write password  
New write community is: < password >  
SYS_console>  
SNMP Trap Message Com m an ds  
When the Switch detects an extraordinary event, it generates a trap.  
A trap is a notification message that may be sent to predefined  
Network Manager Stations. A trap event may be a reset (cold or  
warm), detection of an interface link status change, an SNMP  
authentication failure due to an incorrect community string, etc.  
The SNMP trap commands let you manage:  
Whether or not the device issues an authentication trap  
The list of selected SNMP Manager Stations to which the  
switch-generated traps will be sent by the SNMP agent. The  
list has a maximum capacity of five entries.  
get-auth  
Displays the Authentication Trap mode:enabled or disabled.  
set-auth  
set-auth {enable|disable}  
This command allows the user to modify the Authentication Trap  
mode.The default value is enable, meaning that the switch will  
generate authentication traps. Changing the mode to disable will  
prevent the switch from sending authentication traps.

Switch in g Database Com m ands  
This section contains instructions for managing the Switching  
Database with the Administrative Interface.Type <switch-db>to  
view related commands.  
The Switching Database consists of 8192 entries. Each active entry  
contains the information relevant to a workstation, characterized by  
its Ethernet MAC Address. Each entry contains the following  
information:  
Entry  
Signifies the index in the Switching Database Table.  
LOCK  
If on (denoted as a +), the entry will not be deleted by the  
switch aging process (static entry). If off (denoted as a -), this is  
a dynamic entry that may be automatically deleted by the  
switch aging process if a packet with this source MAC address  
is not received during an aging time period.  
MGMT (not user configurable)  
If on (denoted as a +), the entry is a system address. Such  
addresses are the switchs individual and group addresses, as  
well as other addresses added by the management system. If  
off (denoted as a -), the entry contains the MAC address of a  
station on the connected network.  
DPORT  
The destination port to which frames with the stated address  
will be forwarded.

Virtual Broadcast Dom ain s (VBC)  
Virtual Broadcast Domains are port-oriented VLANs that allow  
broadcast Ethernet addresses to be broadcasted (transmitted) to the  
assigned ports in that VBC.The VBCs do not require a SVLAN to be  
configured to allow packet switching between assigned ports in a  
VBC. Broadcast packets (destination address of FF FF FF FF FF FF)  
remain within the VBC where they are received and are transmitted  
to only the ports in a SVLAN that are members of the receiving VBC  
port.  
A VBC VLAN can be built from any combination of ports. However,  
ports in a VLAN cannot overlap. If you assign the same port to  
multiple VLANs, they become one VLAN which contains all of the  
original VLAN ports.You can view VLAN settings by using the CLI  
get-con-matrix”command which shows the connectivity  
matrix of all the ports (identifies the ports sending frames to other  
ports).  
get-con-matrix  
Retrieves the current connectivity matrix for the switch.The first  
column is the source port.The other columns are destinations to  
which frames from a given source port (determined by which row)  
may be forwarded. Unlearned addresses will be forwarded to all  
destinations marked with a + in the source ports row. Learned  
addresses will be forwarded to their destinations only if the  
destination is marked with a +”in the source ports row. Note that  
the switch has a default VBC that contains all the ports in the switch  
that are not assigned to a VBC VLAN.The following example shows  
that Ports 1-4 are in VLAN #1; the remaining ports are in the default  
VLAN. Also see the example for get-vbc-tbl run.

Virtual LAN Commands  
set-vbc-domain  
set-vbc-domain {run|nvram|all} <port_list>  
This command establishes a Virtual broadcast domain. port_list is a  
dash-separated list of ports to group into a broadcast domain. For  
example:  
set-vbc-domain all 2-5-6-7  
Creates a virtual broadcast domain of ports 2, 5, 6, and 7.  
del-vbc-domain  
del-vbc-domain {run|nvram} <domain_id>  
This command deletes a virtual broadcast domain. domain_id is the  
vbc id number as identified by get-vbc-tbl.  
Note  
When you use the set-vbc-domain command with the all parameter,  
both the runtime and nvram databases are changed. In case you need  
to delete the mentioned vbc entries, you should run the del-vbc-  
domain command twice with run and nvram parameters.  
get-vbc-tbl  
get-vbc-tbl {run|nvram}  
This command retrieves the list of defined virtual broadcast domains.

Virtual LAN Commands  
Security VLANs  
Each Security Virtual LAN (SVLAN) can contain one or more groups of  
ports.The group in a SVLAN are only allowed to send and receive  
packets to groups in the same SVLAN. If a group is not assigned to a  
specific SVLAN, it remains in the default SVLAN. Unicast packets with  
unknown destination addresses are sent to all port members in a  
SVLAN. Broadcast packets (broadcast address ffffffffff) remain within  
the VBC where they are received and are transmitted to only the  
ports in an SVLAN that are members of the receiving port VBC.  
set-sec-vlan  
This command establishes a Security Virtual LAN.  
The SVLANs are group-oriented.There are eight groups of ports on  
the 8116 switch.

set-speed-sel  
set-port-sel <port-number> {asense|100|10}  
This command specifies if port-number will negotiate a 10Mbps or  
100Mbps connection, or it will autosense. If the switch is having  
difficulty auto-sensing the wire speed, use this command to set the  
correct value.  
Note  
If the ports link partner is in Full Duplex mode and not in ASENSE (or  
auto-negotiation)mode, ASENSEcannot be selected as the line speed  
of the port.  
set-port-state  
This command can be used to enable or disable a port when the  
Spanning Tree algorithm is not running.When Spanning Tree is  
running, set-prt-enb should be used instead.  
set-port-state < port-number>

set-aggr-mode  
This command sets the device mode:aggressive or relax backoff  
algorithm.  
SYS_console>set-aggr-mode  
[arg #0] enter either {enable | disable}  
SYS_console>  
The AT-8116 implements the truncated exponential backoff  
algorithm defined by the 802.3 standard.The set-aggr-mode  
command controls the number of consecutive retransmit trials  
(necessitated by collisions) before restarting the backoff algorithm.  
In aggressive mode the AT-8116 restarts the backoff algorithm after 4  
consecutive transmit trials instead of 16.This results in the switch  
being more aggressive in accessing the media following a collision.

Span n ing Tree Com m ands  
Spanning Tree automatically configures a loop-free topology in a  
bridged environment. However, note that the bridge on this switch  
is not VLAN-based and only one spanning tree is allowed regardless  
of the number of VLANs.The Spanning Tree agent is implemented in  
conformance to the IEEE 802.1d standard. Once spannning tree is  
enabled, it remains enabled even through resets or start ups.  
Listed below are the configuration commands pertinent to the  
operation of the Spanning Tree algorithm.Type <sp-tree> to view all  
the related commands. For spanning tree defaults, see Appendix B,  
System Defaults.  
get-stp  
Retrieve the current state of Spanning Tree. Options are enable or  
disable.  
Note  
The default state is disabled for spanning tree.  
set-stp  
This command enables or disables the Spanning Tree protocol.  
Spanning Tree is enabled by default, in accordance with 802.1d.  
Enabling or disabling Spanning Tree will not take effect until the  
SNMP agent is reset, via warm-reset, cold-reset or a power cycle.

Usin g an SNMP Manager  
This chapter contains instructions for the configuration and  
management of the AT-8116 SNMP Management System.  
Con figurin g th e AT-8116 SNMP Agen t  
Once connected to the network and powered ON,the AT-8116 starts  
operating according to factory-set default values.However,to ensure  
proper operation and maximum performance specific to your  
network configuration and to provide SNMP access, some  
environment-specific parameters must be configured through the  
Command Line Interface.  
If you are configuring the switch for the first time:  
Global Setup  
1. Connect a terminal to the RS-232 connector.  
2. Log in to the Command Line Interface.  
3. Initialize all the AT-8116 parameters to their default values (see  
Table 1, System Default Values). Use the following command  
sequence:  
init-nvram (deletes all current NVRAM configrations)  
warm-reset (loads the NVRAM configuration)  
4. Wait until you see the LOGIN prompt again. Login to the CLI. Now  
all system parameters have been initialized to their default values.

Using an SNMP Manager  
IP Setup  
1. Modify the system IP configuration to match your IP network. Use  
the set-ip-cfg command in order to provide an IP address, a  
netmask and a broadcast address (see IP Commands). For  
example:  
set-ip-cfg 129.001.001.064 255 255.255.255.0  
129.001.001.000  
Check that the actual IP configuration matches the desired one:  
SYS_console>get-ip-cfg  
The device IP address, netmask and broadcast are:  
IP address: 129.001.001.064  
IP netmask:255.255.255.000  
IP broadcast: 129.001.001.000  
2. Set the default gateway address using the set-gatew command.  
This should be a station that can route IP packets to non-local IP  
networks. For example:  
SYS_console>set-gatew 129.1.1.1  
3. Confirm that the default gateway IP address was properly  
accepted:  
SYS_console>get-gatew  
Device default gateway address is :  
129.001.001.001

SNMP Setup  
1. Set up the SNMP communities strings for the two access modes:  
read and write (see SNMP Commands). Confirm that the read and  
write communities were properly accepted. In this example, the  
Read community string is public; the Write community string is  
private. To set community strings:  
SYS_telnet>set-comm read public  
New read community is: < public >  
SYS_telnet>set-comm write private  
New write community is: < private >  
SYS_telnet>  
to read if accepted:  
SYS_telnet>set-comm read public  
New read community is: < public >  
SYS_telnet>set-comm write private  
New write community is: < private >  
SYS_telnet>

Software Troubleshooting  
This chapter provides troubleshooting hints for problems you may  
encounter when trying to manage the AT-8116 using an SNMP  
Management System.  
If your SNMP Manager has trouble communicating with the  
SNMP Agent in the Switch, check your SNMP configuration  
parameters.  
Your Network Administrator can help determine if your IP  
configuration (IP Address, netmask and broadcast address) is  
correct. If the SNMP management workstation is on a different  
network, be sure that you have defined an appropriate Default  
Gateway IP Address.  
Check the community string configuration by using the get-  
comm * command.  
If you are not receiving any traps, check that you have  
correctly entered the SNMP Management Workstation  
address in the trap receiver table. Display the table using the  
get-trap-tbl command. Check that both the IP Address and  
the community string are correct.  
If the network management station does not receive  
authentication failure traps, check for the Authentication  
Mode using the get-auth command.  
Check that you have a correct physical connection to the  
Switch. Check the LINK status.  
Test the connection to the SNMP Management Station by  
pinging it. Use the CLI: ping.  
If the networks physical topology has changed recently (e.g.  
an SNMP Management Station has been moved from one  
segment to another), the ARP cache may be out of date. You  
can use the del-arp-entry command to flush the cache.
