Troubleshooting
1 Telnet to the switch.
2 Log in to the switch.
3 Type to verify that the system running the EPICenter is a trap receiver, or
show management
if the device is running SNMPv3.
show snmpv3 target-addr <ipaddress>
An Extreme switch can support a maximum of 16 trap destinations with ExtremeWare 6.0 or greater. If
EPICenter is not specified as a trap destination, then no SmartTraps are sent, and the data is not
refreshed. If you need to remove a trap receiver from a device running SNMPv1, use the command:
config snmp delete trapreceiver <ipaddress>
For devices running SNMPv3, use the commands:
config snmpv3 delete target-addr <ipaddress>
config snmpv3 delete target-params [ <param> | all ]
config snmpv3 delete notify [ <notify-name> | all-non-defaults ]
See the ExtremeWare Software User Guide for information on using these commands. These commands
will also delete SNMPv1 trap receivers.
For convenience you may want to create a Telnet macro containing these commands. You can use a
user-defined variable to input the target IP address.
Problem: Need to change SNMP polling interval, SNMP request time-out, or number of SNMP
request retries.
You can change the default values for the SNMP polling interval, the SNMP request time-out, or the
number of SNMP request retries, through the Administration applet, Server Properties page. See
"Polling Types and Frequencies" on page 132 for more information about modifying these properties.
See Chapter 15 in the EPICenter Reference Guide for detailed information on the EPICenter
Administration applet.
Problem: Need to change the Telnet or HTTP port numbers used to communicate with managed
devices.
You can change the port numbers for all managed switches through the Administration applet, Server
Properties page.
See Chapter 15 in the EPICenter Reference Guide for information on the EPICenter Administration applet.
Problem: Telnet polling messages can fill up a device's syslog file.
The EPICenter server uses Telnet polling to retrieve certain switch information such as Netlogins, FDB
data (if FDB polling is enabled) and power supply information. On older versions of ExtremeWare
EPICenter uses Telnet polling to get EDP topology and ESRP information. By default, EPICenter does
status polls every five minutes and detailed polls once every 90 minutes. Each telnet login and logout
message is logged to the switch's log file, and will eventually fill up the log.
In addition, in some cases EPICenter needs to disable CLI paging so the poller can retrieve the full
results of some CLI commands. An entry is created in the switch log for each disable clipaging
command, which can also contribute to filling up the log.
