Switch Configuration Screen
2H28-08R SmartSwitch 2208 User’s Guide 5-37
The following describes each field of the Switch Configuration screen:
Switch Address (Read-Only)
Displays the MAC address of the switch.
Number of Ports (Read-Only)
Displays the total number of switched ports on the 2H28-08R.
Type of STA (Selectable)
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 selections are 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 2H28-08R
keeps an address in its switch table before discarding it. An address is
automatically discarded when a valid Bridge Protocol Data Unit (BPDU)
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.
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.
• Learning: The switch is learning the addresses on this interface. The
switch enters the learning state when the Transparent Database is
created (during start-up or after being deleted), or when the Spanning
Tree Algorithm detects a network topology change.
