Switch Configuration Screen
2E48-27R/2E49-27R User’s Guide 5-39
The following describes 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 2E4X-27R. Depending
on the optional interfaces, there can be 24 through 27.
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 selection is IEEE, DEC, and
None. To set the STA, refer to Section 5.10.1.
Age Time (Modifiable)
Allows the user to set the amount of time (in seconds) that the 2E4X-27R
keeps an address in its switch table before discarding it. An address is
automatically discarded when a valid frame 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 5.10.2.
Port # (Read-Only)
Lists each switched port on the device. 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 display in this field. These states are
described as follows:
Disabled: Management disabled this interface. No traffic is received or
forwarded while the interface is disabled.
Listening: The switch is not adding information to the Transparent
Database. The switch is monitoring the Bridge Protocol Data Unit
(BPDU) traffic while preparing to move from the learning to the
forwarding state.
