Enabling STP on the Switch
To enable STP on your Switch:
1
From the VT100 Main Menu, select SWITCH MAN-
AGEMENT. The Switch Management screen is dis-
played.
2
In the Management Level field, choose Unit.
3
Choose the SETUP button. The Unit Setup screen is
displayed, as shown in Figure 5-15
.
4
In the Spanning Tree field, specify Enable.
5
Choose OK.
You cannot enable STP if you have set up resilient
links on any of the Switch ports, or if you are using
VLAN 16.
CAUTION:
If STP is enabled on your Switch 1000
and the Switch is connected to another Switch
1000, a Desktop Switch, or a repeater, the Bridging
Mode of the Switch must be set to Forward to All.
If the Bridging Mode of the Switch 1000 is set to
Forward to Backbone, link losses may occur on
your network. For more information about setting
the Bridging Mode for your Switch, refer to “Setting
Up the Switch Unit” on page 4-9.
