forwarding. If blocked, it will not be allowed to transmit or receive traffic.
Time of Addition
Shows the date and time when this MAC address was first seen on the
port.
Age/Hold
If at least one user module has decided to block this MAC address, it will
stay in the blocked state until the hold time (measured in seconds)
expires. If all user modules have decided to allow this MAC address to
forward, and aging is enabled, the Port Security module will periodically
check that this MAC address still forwards traffic.
If the age period (measured in seconds) expires and no frames have
been seen, the MAC address will be removed from the MAC table.
Otherwise a new age period will begin.
If aging is disabled or a user module has decided to hold the MAC
address indefinitely, a dash (-) will be shown.
3.13 Warning/Event Settings
Since industrial Ethernet devices are often located at the endpoints of a system, these devices will
not always know what is happening elsewhere on the network. This means that an industrial Ethernet
switch that connects to these devices must provide system maintainers with real-time alarm
messages. Even when control engineers are out of the control room for an extended period of time,
they can still be informed of the status of devices almost instantaneously when exceptions occur. The
Weidmüller switch supports different approaches to warn engineers automatically, such as email and
relay output. It also allows to store the log data of events both locally and in a SYSLOG server.
3.13.1 Configuring Relay Warnings
The Fault Relay Alarm function uses relay output to alert the user when certain user-configured
events take place.
