• Expansion Modules and Port Trunks
An expansion slot cannot be made part of a port trunk unless an expansion module has
been installed.
• Broadcast Frame Control on Expansion Modules
Broadcast frame control is not reliable when used on ports on expansion modules. For
this reason it is not recommended that you use this feature to regulate the flow of
broadcast frames on expansion modules.
• Port Trunking on Expansion Modules
If you intend to create a port trunk using expansion modules in an AT-8024M or
AT-8016F switch, it is recommended that both expansion modules be of the same type.
You should not create a port trunk using different types of expansion modules.
• Limited Security Mode
- The maximum number of MAC addresses must be set a port at a time. You cannot set
the number for a range of ports.
- If you do not specify a port when configuring the maximum number of MAC addresses,
the management software applies the value to Port 1.
• RMON Groups and SNMP
The AT-S39 management software supports the following RMON groups through
SNMP:
- Groups 1 - Statistics
- Group 2 - History
- Group 3 - Alarm
