Problem: Multiple VLANs have the same name.
A VLAN is defined by the name, its tag value, and its protocol filter definition.
ExtremeWare Enterprise Manager allows multiple VLANs of the same name if one of
the other defining characteristics of one VLAN is different from the other.
Problem: Multiple protocols have the same name.
ExtremeWare Enterprise Manager allows multiple protocols of the same name if one of
the other defining characteristics of one protocol is different from the other.
Problem: Created a new protocol in VLAN Manager, but the protocol does not appear
on any switch.
When a new protocol is created, it is stored in the Enterprise Manager database. The
Enterprise Manager only creates the protocol on a switch when the new protocol is used
by a VLAN on that switch.

Problem: Discovery hangs if a large number of addresses is specified.
A very large discovery can cause the discovery process to hang because there is
insufficient memory available to the browser to process the number of addresses. This is
a limitation of the browser.
To recover, restart the browser. Then split your discovery request into multiple requests
that involve a smaller number of addresses. Discovery prodisplays 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 names "Summit1," "Summit2," "Summit4," or
"Summit48," depending on the type of switch. You should change these names to
unique names using the ExtremeWare CLI or ExtremeWare Vista.
