Clarifications and Known Behaviors
ExtremeWare 7.1.1 Release Notes 39
Cannot Add FDB Entry for Management VLAN
You cannot add an FDB entry for the management VLAN (PD2-156475718)
Static FDB Entries and Rate-Shaping
If you create a static FDB entry on a port configured for rate-shaping, the static entry incorrectly ages
out. Static entries should not age out (PD2-97150551).
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 and 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
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).
Round Robin Load Sharing
If a port in a round robin load share group is removed, the traffic that was being transmitted on that
link will be distributed on only 1 of the other active load share links in the round robin group. The
traffic is not distributed evenly between the remaining ports (6977).
Port Based Load Sharing on Summit7i
Port-based load sharing on the Summit7i requires ingress ports to be on the same side of the switch
(ports 1 - 4, 9 - 12, 17 - 20, and 25 - 28 on the left, ports 5 - 8, 13 - 16, and 21 - 24 on the right) as the 8
ports in the load share group for all ports in the load share group to transmit/receive traffic (6975).
Alpine and Cross Module Load Sharing
The I/O module configured to contain the “master” port must be physically present in a cross-module
load sharing group for the system to pass traffic (8589, PD2-119098401).
