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 network’s 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has changed recently (e.g. an SNMP Management Station has been moved from one segment to another), the ARP cache may be out of date.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.
