Inventory Manager - Extreme Networks EPICenter Guide Manual

Inventory Manager

Problem: Some of the switches in an ESRP-enabled VLAN are missing from the ESRP Manager
applet.
Make sure that the Hello Timer (ESRP Timer) is set to the same interval for all ESRP-enabled switches. If
there is a timer mismatch, ESRP will not function correctly, and the ESRP Manager applet will not be able
to detect ESRP switch neighbors that are not being managed by the EPICenter software.
Problem: Devices running ExtremeWare 4.x are not being polled for ESRP information.
The EPICenter server uses Telnet polling to add and update ESRP information for devices running
ExtremeWare 4.x. If you have the "Poll devices using Telnet" option disabled in the Administration applet,
no ESRP information will be obtained for these devices. You can enable telnet polling through the Server
Properties page in the Administration applet. See Chapter 15 in the EPICenter Reference Guide for more
information.
Inventory Manager
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 can change the way names are displayed through a sever property in the Administration applet. You
can display devices in the Component Tree by name or by IP address and name. See Chapter 15 in the
EPICenter Reference Guide for more information on setting EPICenter server properties.
Problem: Discovery does not display the 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.
Problem: For a device selected under Status, the Device Information panel shows incorrect
information, and the device image is not displayed correctly.
This can be caused by a device IP address that is in conflict with another device on the network (a
duplicate IP address). Remove the problem device from the EPICenter inventory, and add it in again with
the correct IP address.
