1.4.1.1.5.7 LLDP
The S2700 supports the Link Layer Discovery Protocol (LLDP) that conforms to IEEE 802.1ab. LLDP is a link
layer protocol used for interconnected devices to obtain the connection information of each other.
Using LLDP, the local NMS can obtain the link layer information of all devices on the local network and details
about the network topology. Thus the NMS can manage a larger area on the network.
The LLDP-enabled interfaces on the S2700 periodically notify the neighbors of its own status. If the status of an
interface changes, the interface sends status update messages to the directly connected neighboring device. The
neighboring device stores the status update message in the standard SNMP MIB. Then the NMS can obtain the
link layer information of the network from the MIB to calculate the topology of the entire network.

1.4.1.1.5.8 Stacking

Stacking means that the switches located in the same place are connected through the stacking cable or high-
speed uplink interfaces, and thus the switches form a reliable switch group. In a switch group, the S2700s are
connected through the stack interfaces multiplexed with uplink GE interfaces. Through stacking, the user can
manage and maintain the switches uniformly; therefore, the stacking reduces the maintenance cost of the
user.The stacked switches must be of the same type.
