A-10 ExtremeWare EPICenter Software Installation and User Guide
To recover, restart the browser. Then split your discovery request into multiple requests
that involve a smaller number of addresses. Discovery displays a warning if your request
involves more than 1500 IP addresses. The actual number of addresses you can
successfully poll will depend on the amount of memory available at that time in your
browser (browser memory is shared among the various running applets).
Problem: Multiple switches have the same name.
This is because the sysName of those switches is the same. Typically, Extreme Networks
switches are shipped with the sysName set to the type of the switch “Summit48,”
“Summit1i,” “Alpine3808,” and so on, depending on the type of switch. You should
change these names to unique names using the ExtremeWare CLI or ExtremeWare Vista.
Problem: Discovery does not display MAC address for some devices in discovery
results list. In addition, may not add the device to inventory (primarily happens with
workstations).
If the MAC address is not found in the first instance of ifPhysAddress, it is not displayed
in the discovery results table. However, when the device is selected to be added to the
EPICenter inventory, the Inventory applet searches all the ifPhysAddress entries for the
device, and will use the MAC address found in this manner. If no MAC address is found
in any ifPhysAddress entry, the device will not be added to the EPICenter database.
Problem: Attempted to add a switch in the Inventory Manager after rebooting the
switch, and received an “SNMP not responding” error.
If a switch has recently been powered on, it may take some time (a number of minutes)
before the device is completely initialized. This will be especially true of chassis devices
with many blades, or devices with a large number of VLANs configured on the device. It
the device has not completed its initialization, the Inventory Add process may return an
error. You can simply wait until the device has finished initializing and try the Add
function again.
