Release Notes for the BayStack 450 10/100/1000 Series Switch
14
311523-C Rev 00
• When mirroring a single MLT member, the monitor port will receive all of the
unknown unicast traffic that is transmitted over the entire MLT.
• When you connect the BayStack 450 switch to an Alteon network interface
controller (NIC), the switch learns invalid MAC addresses whenever
autonegotiation for a gigabit MDA port is enabled (the invalid MAC addresses
eventually age out). This problem occurs only when you reset the switch (via
the console interface main menu or during a power cycle) and does not affect
the correct operation of the BayStack 450 switch.
Connecting to Accelar Gigabit Ports
The BayStack 450 switch supports gigabit MDA port connections to the Nortel
Networks Accelar switch gigabit ports, with the following restrictions:
• Autonegotiation
is not
supported on the Accelar 1000BaseSXWG (ASIC
Version
GMAC 2
).
When connecting to this version, disable autonegotiation on the BayStack 450
switch’s gigabit MDA port.
• Autonegotiation
is
supported on the Accelar 1000BaseSXWG (ASIC Version
GMAC 4
).
When connecting to this version, set autonegotiation to enabled (or disabled)
at both ends of the communications link. The autonegotiation setting must be
identical at both ends of the communications link.
You can determine the ASIC version number for the 1000BaseSXWG gigabit card
using the following command from the Accelar console port:
Accelar-1100# sh sys info
