Release Notes for the BayStack 450 10/100/1000 Series Switch
•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:
