DLE28-MA User’s Guide
The following describe each field of the Switch Configuration screen:
Switch Address (Read-Only)
Displays the base MAC address of the switch.
Number of Ports (Read-Only)
Displays the total number of switched ports on the module. Depending on
the number of optional interfaces installed, there can be up to 30 ports for
the DLE28-MA.
Type of STA (Toggle)
Allows the user to set the method that switches use to decide which
switch is the controlling (Root) switch when two or more switches exist in
parallel (Spanning Tree Algorithm). Valid entries include IEEE, DEC,
and NONE. To set the STA, refer to Section 5.18.1.
Age Time (Modifiable)
Allows the user to set the amount of time (in seconds) the DLE28-MA
keeps an address in its switch table before discarding it. The modules
automatically discard an address from their switch table when a valid
packet is not received from that address within the time specified in the
Age Time field. To change the Age Time field from the default value of
300 seconds, refer to Section 5.18.2.
Port # (Read-Only)
Lists each switch port on the module. If the number of ports is greater
than eight, then the additional ports are listed on subsequent screens.
MAC Address (Read-Only)
Displays the hardware address assigned to each listed port.
State (Read-Only)
There are five states that can be displayed in this field. These states are
described as follows:
