AT-S24 Version 2.2.2 Management Software Release Notes
PN 613-50247-00 Rev A 5 Allied Telesyn International
• Clearing Dynamic MAC Addresses
AT-S24 now contains a command for clearing all dynamic MAC addresses from the MAC
address table. For information on the command, refer to the section “Clearing All Dynamic
MAC Addresses” in Chapter 4 of the AT-S24 Version 2.01 User’s Guide.
Resolved Issues in Earlier Version 2.01
• SNMP Network Manager and Expansion Modules
You can use an SNMP network manager to view status information on the expansion
modules installed in the switch.
•“newRoot” and “topologyChange” Traps
The management software now properly transmits the STP “newRoot” and
“topologyChange” traps.
• IGMP and Multicast Address Entries
Disabling IGMP on the switch automatically deletes all multicast address entries.
• Spanning Tree Protocol and BPDU Packets
The STP algorithm now handles improperly configured BPDU packets from other devices,
reducing the possibility of unexpected network loops in some environments.
• Get Port From MAC Address Selection
The Get Port From MAC Address selection in the MAC Address menu now works correctly.
Operational Notes
• Web Browser User Name and Password
If you assign a password to Omega, the Omega interface will prompt you for both a user
name and the password when you start a web browser management session. The user
name is “admin”. The user name cannot be changed.
• Spanning Tree Protocol (STP) and Port Trunking
Do not activate STP on ports that will be part of a port trunk. You should check to be sure
that STP has been disabled on the ports before you create a port trunk.
• Link Up and Link Down Traps
This version of the switch software sends a Link Up or Link Down trap whenever a cable is
connected or disconnected from a port trunk. However, instead of sending only one trap,
the software sends two. The extra trap does not affect the network operations of the
switch.
