Lan acceptance Specification

The purpose of the acceptance is to reflect the openness and reliability of the LAN. For local area networks, some relevant units and experts are preparing some feasible and useful acceptance tests recently. These specifications are being verified by the new bidding committee and will soon become the nationally recognized local area network construction acceptance specifications. Some acceptance tests are described as follows:
1. Test the transmission media/Integrated Wiring System
According to GB/T50312 or ISO/IEC11801, the channel, or DTX-xFM optical cable test module can be executed using a DTX-1800 such as fluke network with its permanent link.
2. Network System Performance Test method:
A. Network System Connectivity: 10 Ping requests are sent to key network devices, such as servers and routers. Sampling tests are conducted at a rate not lower than 10% of the total number of access layer devices. If the number of sampling devices is less than 10, all tests are performed. select at least one port for each sampling device, that is, the test point, test points should cover different subnets and VLANs.
B. for throughput, latency, and packet loss rate tests, refer to RFC2544): All tests should be conducted on the backbone links of the core layer. All tests should be conducted on the uplink links from the aggregation layer to the core layer; sampling tests are performed on the uplink links from the access layer to the aggregation layer at a rate of no less than 10%. If the number of sampling links is less than 10, 10 links are calculated or all tests are performed; end-to-end links are the network paths from users who pass through the access layer, aggregation layer, and core layer to users. If the number of end users is no less than 5%, perform calculation or all tests based on 10 results.
C. Link Layer health test: elasticsearch performs health check through dedicated hardware in the second generation. elasticsearch connects to the network through the mirror port of the switch or the link through the aggregation TAP. During testing, the link must meet the following requirements during normal operation.

Test Indicators	Technical Requirements
	Shared Ethernet /Half-duplex switched Ethernet	Full-duplex switched Ethernet
Average Link Utilization bandwidth %)	≤40%	≤70%
Broadcast rate Frame/Seconds)	≤50Frame/Seconds	≤50Frame/Seconds
Error Rate % of total frames)	≤1%	≤1%
Collision rate % of total frames)	≤5%	0%

3. Network System Function Test Method
A. Test the Address Allocation Function: You need to test each subnet/VLAN. Connect the tester to a physical port of a subnet/VLAN. The tester simulation terminal requests the network address. If the network needs to pass 802.1X authentication, the test should be supported.
B. subnet/VLAN division test: The test tool is connected to a physical port of each subnet under test. The test tool sends Ping broadcast packets, SNMP queries, and listens to packets in the network, automatically detects all devices and terminals connected to the subnet and generates a list of nodes in the subnet. Then, PING other VLAN/subnet sites that should be accessible, so that you can receive a response each time. Through the automatic search function of the second generation of elasticsearch, elasticsearch allows you to conveniently configure and allocate Site Resources on subnets or VLANs.
C. through QoS, the Ethernet system can provide priority services for video streams transmitted over the network and other data with high real-time requirements. When the network is overloaded or congested, QoS ensures that important business volume is not delayed or discarded, it also ensures efficient network operation.
Conclusion:Through the above acceptance tests, the network administrator can evaluate the end-to-end connectivity, openness, and performance of the LAN. These tests can be used as an acceptance evaluation method for Integrators and network administrators during LAN delivery. The integration test function of the second generation of elasticsearch network can meet the test requirements for network acceptance. In addition, when a problem occurs, you can provide in-depth analysis to quickly solve the problem.
