Discovery

Display discovered nodes by selecting one or more of the following (all are selected by default):

●

Gigamon—displays Gigamon nodes

●

Manual—displays manually added nodes

●

CDP/LLDP—displays nodes discovered through CDP or LLDP

Note: If both CDP and LLDP packets are discovered on the same port, the topology construction relies on LLDP packets over CDP.

Taps—display TAPs

Device Types

Display only nodes of the selected type, such as router, switch, virtual switch, load balance, and so on. You can select more than one type.

Vendor

Display manually added nodes that are from the specified vendor. Enter the vendor’s name in the Vendor field.

Models

Display only the specified Gigamon model. You can select more than one model.

Cluster IDs

Display the clusters or nodes with the specified IDs. The drop-down list displays the IDs of the clusters and nodes in the topology. You can select more than one node or cluster.

Node Status

Display nodes with the specified status. The possible statuses are OK, Error, and Warning.

In the following figure, all Discovery filters are selected and two clusters are specified in the Cluster ID(s) field. Only items that meet the filter criteria are displayed while all other elements are grayed out.
