VLAN Topology view
The VLAN Topology view displays a map of the VLAN traffic for devices on your network. You can
also view primary, isolated, and community PVLAN in the VLAN Topology and Product List. You can
access the STP or RSTP Topology from this view. To display topologies for VLANs, you must have the
Main Display - VLAN privilege in your user role. For more information about privileges, refer to
“User
Privileges” on page 1935.
The VLAN Product List contains all the port VLANs and PVLANs known to the system. Within each
VLAN, products that are a part of that VLAN display. You can select which VLAN topology you wish to
view. The default VLAN ID is the first entry in the VLAN Product List.
For more information about the components and customization of the topology map, refer to the
following sections:
• “IP topology map components” on page 420.
• “Topology map elements” on page 421.
• “Viewing STP/RSTP topology” on page 416.
• “Topology map layout” on page 423.
For more information about functions you can perform on the topology map, refer to “Topology Map
functions” on page 375.
STP/RSTP topology
You can display topology maps for STP or RSTP configurations from the VLAN Topology view. Before
you display the STP or RSTP topology, make sure you meet the following requirements:
• The devices are running FDP or LLDP.
If you do not enable FDP or LLDP on a product, the product displays without any links.
• The snIfStpTable MIB table (OID.1.3.6.1.4.1.1991.1.1.3.5.2) is enabled on the device and has
either STP or RSTP configured. This MIB is not supported on third-party products.
Viewing STP/RSTP topology
To view this topology map, complete the following steps.
1. Select VLAN Topology from the view list on the Product List toolbar.
Pause on the STP button. A tool tip appears, indicating whether STP is on or off.
2. If STP is off, click STP to turn it on.
3. Select a VLAN or PVLAN from the VLAN Product List.
All devices with STP mode on the selected VLAN display on the map, regardless of their
connectivity. STP-enabled devices display with a Bridge ID.
The STP Topology view supports both STP and RSTP; however, the map does not differentiate
between the two protocols. You can use the STP/RSTP report to determine which protocol is
enabled on a device. MSTP protocol is not supported.
When STP mode is active, dynamic updates is not active. Instead, a Refresh button displays on
the Topology Map toolbar, next to the STP button, to enable you to manually trigger an update.
