Clarifications, Known Behaviors, and Resolved Issues
FDB
FDB Entries Disappear Before Aging Timeout
If you configure fdb agingtime to 100,000 seconds, the FDB entries disappear before the 100,000
seconds. The values disappear around 200+ seconds (PD2-248579601).
Cannot Add FDB Entry for Management VLAN
You cannot add an FDB entry for the management VLAN (PD2-156475718)
MAC Security
The source FDB address configuration will not discard ICMP packets (16340).
FDB Aging Timer
In ExtremeWare 6.2.0, the default value of the FDB aging timer was set to 1800 seconds on a newly
configured ExtremeWare 6.2.0 switch. In ExtremeWare 6.2.1 the default value has been changed back to
300 seconds. However, when upgrading from ExtremeWare 6.2.0 to ExtremeWare 6.2.1, the default value
will remain 1800 seconds. For upgrades from ExtremeWare 6.1.9 (or earlier) the default value will
remain 300 seconds. The FDB aging time can still be set to all previous values (1-85QD3).
Configure Less Than 400 Ports in a VLAN
If you use the clear slot command (which flushes the FDB) when there are 256,000 or more FDB
entries, the watchdog timer can cause the switch to reboot. To avoid this, configure less than 400 ports
in a VLAN (PD2-90223209).
Load Sharing
Removing Modules During CMT Testing Causes Loss of Traffic
When you perform the CMT trunk up/down tests and remove the modules and re-insert them, the
switch receives 50% less traffic. As a workaround, after you re-insert the modules and notice a 50% loss
of traffic, remove the ports and re-insert them (PD3-2162531).
Backplane Algorithm Not Working Properly When Changing the Algorithm from
Address-Based to Port-Based
When the backplane algorithm is changed from address-based to port-based the backplane still behaves
as an address-based algorithm, causing the traffic to appear on all ports instead of one port. As a
workaround, save and reboot the switch after changing the backplane algorithm (PD2-238168901).
Autonegotiation
Load sharing ports must be configured with autonegotiation set to on. Load sharing ports will not
transmit traffic correctly using any other setting (PD2-64617405).
