Clarifications and Known Behaviors
ExtremeWare 7.3.1b3 Release Notes 85
NOTE
Numbers marked with an asterisk (*) have appreciable discrepancy on the higher side. For example, if
the port is configured for 70% bandwidth, 72% bandwidth might be seen.
SecureMac Flags Not Shown
SecureMac flags are not shown on FDB entries of rate shaped ports (PD2-171300406).
Locking and Unlocking Learning
If you configure a rate shaping port to lock learning and unlock learning, the loopback FDB is not
flushed. This causes traffic destined for the port to be flooded. You must manually flush the FDB using
the
clear fdb command (PD2-124568416).
1000Base-T Ports as Loopback Ports
If the loopback port for bi-directional rate shaping configurations is configured on 1000Base-T ports, the
speed of that port cannot be changed from 1000 Mbps to 100 Mbps as the bandwidth settings will not
be accurate when configured in 100 Mbps mode.
EAPS
Configuring Cross Module Trunking Causes EAPS Failure
When configuring cross module trunking, if you connect a slave port, the transit switch does not
forward the EAPS hello packets and the EAPS ring is in the failed state (PD2-238232230).
