5.3.13 LLDP Protocol and Associated Features (LAG/VCS Monitoring)
The LLDP protocol feature on devices is a way to advertise data that is useful for discovering information about a network
link port. If the administrator manually enables LLDP for each device and sets the direction as BOTH, the links between the
devices will appear on the physical map GUI as the devices are (re)discovered.
Note: For a complete description of LLDP and its parameters, refer to the iMAP Software Reference Manual.
The administrator can activate and control LLDP for one or multiple devices using an application. Moreover, one minute
after LLDP has been activated (with a direction of BOTH), the device will be re-discovered and the links will appear on the
physical map based on the LLDP data.
Caution: It is not recommended to include a HUB switch when using the LAG/VCS monitoring feature or any feature that uses the
LLDP application. A HUB switch provides a one-to-many configuration for data traffic, so all LLDP information is propagated
to multiple devices. As a result, the devices will build an incorrect set of connection information. Moreover, the topology
displayed will not be correct, and can even look like a loop.
Like other applications, the administrator can select one or more devices, right click, and then choose Provision -> LLDP
Configuration, and then bring up the application, as shown in the following figure.
Note: You can also select Tools -> Application Manager, select LLDP Configuration in the pull-down menu, and add devices.
FIGURE 5-60 LLDP Application for iMAP Devices
The application shows for each device the following:
• Device Attrs. - These are listed and allowed to be changed in the first LLDP MultiDevice Wizard panel.
• Direction - This can be TX, RX or both.
• No LLDP - Whether LLDP is active or not on the port. (This is controlled by the Notify option.)
Options - There are multiple options, and these are controlled by the second LLDP MultiDevice Wizard panel.
The administrator can choose one or multiple devices with which to activate and control LLDP, as explained below.
5.3.13.1 LLDP for Multiple Devices
Note: In most cases, the administrator should first choose all the relevant devices that will have LLDP activated and set the attributes
for all devices. The administrator could then if desired choose a device and change specific attributes. Otherwise, if settings
are applied to a specific device, and changes are then made for multiple devices that affect those settings, any changes to that
specific device would be overwritten.
When more than one device is chosen and the Configure LLDP Button is selected, the LLDP MultiDevice Wizard panel
appears. The following figure shows the first panel when multiple devices are selected.
