Discovery Mode

Description

Based on LLDP

Links are discovered through the Link Layer Discovery Protocol (LLDP). The LLDP protocol is a layer 2 link discovery protocol defined in IEEE 802.1ab. Through this protocol, you can get layer 2 information about all devices connected to the NMS. This helps to expand network management scale and grasp detailed network topology and change information. It also helps to discover improper configuration on the network and report the information to the network administrator.

You need to enable the LLDP function of devices.

Based on CDP

Links are discovered through the Cisco Discovery Protocol (CDP). This protocol is mainly used for link discovery between Cisco devices.

You need to enable the CDP function of devices.

Based on the MAC forwarding table and ARP forwarding table

You can use the MAC and ARP forwarding tables to discover links if the LLDP and CDP functions are not enabled. If links between devices change, you can also manually discover links.

Some links discovered based on the MAC forwarding table may not exist. For these links, you can use the link hiding function to hide them.
