Can eSight Manage Links of What Network Devices

Question

Can eSight manage links of what network devices?

Answer

eSight supports 3 links and Layer 2 links. The details are as follows:

Layer 3 link: An IP link is a Layer 3 link between devices. The IP addresses for interfaces at both ends of an IP link contain a 30-bit subnet mask.

Layer 2 link: A Layer 2 link between devices can be displayed in the physical view. eSight supports the following discovery methods.

Discovery Method

Description

LLDP-based

A Link Layer Discovery Protocol (LLDP) link is a Layer LLDP link that uses LLDP for discovery.

LLDP is a Layer 2 discovery protocol defined in IEEE 802.1ab. eSight can use LLDP to obtain information about Layer 2 neighboring devices and detailed network topology information, which helps to expand the network. In addition, eSight can use LLDP to detect improper network configurations, which helps the network administrator to optimize network configurations.

To use this discovery method, enable the LLDP function first.

CDP-based

Cisco Discovery Protocol (CDP) is used to discover links among Cisco devices.

To use this discovery method, enable the CDP function first.

Based on the MAC and ARP forwarding table

Links can be also discovered based on the MAC and ARP forwarding table if LLDP or CDP is not enabled. If links between devices change, users can 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.
