MAC address table
Switching of frames is based upon the DMAC address contained in the frame. The
industrial managed switch builds up a table that maps MAC addresses to switch ports
for knowing which ports the frames should go to (based upon the DMAC address in the
frame). This table contains both static and dynamic entries. The static entries are
configured by the network administrator if the administrator wants to do a fixed mapping
between the DMAC address and switch ports.
The frames also contain a MAC address (SMAC address) that shows the MAC address
of the equipment sending the frame. The SMAC address is used by the switch to
automatically update the MAC table with these dynamic MAC addresses. Dynamic
entries are removed from the MAC table if no frame with the corresponding SMAC
address have been seen after a configurable age time.
MAC table configuration
The MAC Address Table is configured on the MAC Address Table Configuration page.
Set timeouts for entries in the dynamic MAC Table and configure the static MAC table
here.
