convergence implements association between Smart Link and Monitor Link. When no upstream
links exist, the S3700 disables the downstream interface and switches traffic between different
paths through the interface association mechanism.

The S3700 provides end-to-end Ethernet OAM complying with IEEE 802.1ag to detect
connectivity faults on a network. The S3700 supports end-to-end connectivity fault detection,
fault notification, fault verification, and fault location.
connectivity faults on a network. The S3700 supports end-to-end connectivity fault detection,
fault notification, fault verification, and fault location.
The S3700 provides the performance management function. Performance management is used
to measure the packet loss ratio, delay, and jitter during packet transmission, and collect statistics
on various types of packets. Performance management is performed at the user access points.
By using performance management tools, a carrier can monitor the network running status and
locate faults through the network management system. The carrier can then check whether the
forwarding capacity of the network complies with the Service Level Agreement (SLA) signed
with users.

The S3700-26C-HI supports hardware-based IEEE 802.1ag.
4.10 LLDP
The S3700 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.
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.
network and details about the network topology. Thus the NMS can manage a larger area on the
network.
The LLDP-enabled interfaces on the S3700 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.

4.11 NQA
As increasing services and applications are deployed on the Internet, traditional network
performance analysis tools (such as ping and tracert) cannot meet customer requirements for
diversified services and real-time monitoring.
