Gigabit Access Switch

This collection of 18 gigabit access to the switch with 2 gigabit switches have 12, with 1 gigabit ports have 6. The number of switches with Gigabit copper port is only 2, gigabit port is 1000base-sx Port, only harbor technology Flexhammer24 with a 1000BASE-LX port. These switches in edimaxes-5224r+, Netcore 7224NSS, Netcore 7224MST, Leapcomm GMS5024 three switches belong to the configurable switch, the port FlexHammer24, flexhamm16i, The thinkerex3124a switch belongs to the third tier switch. The remaining 11 switches are a 2-tier manageable switch.

Excellent performance

In general, the performance of the participating Gigabit access switches is not bad, and many switches are very difficult to perform. Accton es3526l, Edimax es-5224rm, Harbor Technology UHammer24, TCL S4228MF, and purple-ray Unisnet ES4242MC, these 5 switches have reached 100% wire speeds in both gigabit and gigabit throughput as well as in part of the network test , the frame loss rate of 0, the 5 excellent performance of the switch is only a small difference in latency, UHAMMER24 Gigabit Port delay is the smallest, but the other 4 the biggest difference is only about 2us.

A very unique switch is the Bay technology flexhammer16i, it is configured with 16 10/100FX fiber interface plus two 1000BASE-SX ports, because our tester does not have a 10/100FX fiber interface card, So only through the photoelectric converter to convert light signals to electrical signals connected to the tester, which will have some impact on the test results, but overall performance is good, only 64-byte frame throughput can not reach the wire speed, and some network testing is only 64-byte frame packet loss phenomenon.

In throughput testing, we tested the throughput of both gigabit and gigabit ports, with 15 switches having a 100%-wire throughput, with only a handful of switches unable to reach 100% wire speeds at the gigabit port throughput. For 6 switches with one gigabit port, we cannot measure the throughput of gigabit ports, and for 12 switches with two gigabit ports, including acctones3526l, Edimax es-5224r+, Edimax es-5224rm, UHammer24, FlexHammer24, Netcore 7224MST, Netcore 7224NSS, TCL s4228mf, purple-ray network unisnet ES4242MC This 9 switch Gigabit port throughput in 64, 512 and 1518 byte frames are all up to 100% wire speeds.

For gigabit access switches, we take a partial network test that corresponds to 10 hundred gigabit ports per gigabit port and a full mesh mapping for other hundred gigabit ports, which is more stringent than the throughput test requirements. 6 Switches with 1 Gigabit ports Shanghai radio and television should be sure Infinite5024, Lipu leapcomm GMS5524, Leapcomm GMS5024 keep the packet loss rate of 0, with 2 gigabit ports in the switch Accton es3526l, Edimax ES-5224RM, Harbor Technology UHammer24, TCL S4228MF and the unisnet ES4242MC 5 Switch performance outstanding, in such conditions is still lost packet rate of zero, this result shows that the switch can make the enterprise network to withstand the largest load. Some switches can reach 100% wire speeds during throughput testing, while in some mesh tests there is a loss of packet, such as Bay Technology's FLEXHAMMER24 performance in throughput testing, while the packet loss rate reached 0.16% and 0.5% in some reticular 512 and 1518-byte frame tests.

Our delay test for gigabit access switches takes into account 100M port with module, Cross module and Gigabit module Three kinds of conditions, mainly in the 100%-wire speed test, the total result is that the gigabit port delay is significantly less than the hundred-gigabit port delay. Most switch hundred gigabit ports are not significantly different from module to cross module latency.

In contrast, Bay Technology's UHAMMER24 switch has the best performance in delay testing, with a gigabit port delay of 3.56us, 7.1us, 15.16us in 64, 512, and 1518-byte frames.

The results of the back-to-back test are basically consistent with the throughput test results. The results of line-end blocking and error-frame filtering tests are similar to each other, and all gigabit access switches in this reference support both functions.

Easy to install

All the delivery switches are very easy to use.

On the power side, the Harbor network, Edimax, the creation of the company's switches in the back panel provides a power switch, which is a very careful consideration. and Netcore and other company's switches on the front panel also provides a reset button to facilitate the switch to reboot. TCL S4226MF, Leapcomm GMS5596 switches all provide a DC power interface.

The majority of the switches that we receive are provided with gigabit upper ports through the installation of Gigabit expansion modules. The UHammer24, FlexHammer24, flexhammer16i three switches are supported by the Bay Network to support hot-swappable. Port network, Accton es3526l, Trendware teg-s224m, Shenzhou digital D-link des3624i and Tcl S4226MF, Leapcomm GMS5596 These switches, the expansion module has very large removal screws, The disassembly work can be done with bare hands.

Shenzhou Digital D-link 3624i, Trendware teg-s224m, Netcore 7224NSS and Netcore 7224MST of these switches have been dedicated to the upper gigabit ports, more switches to support the identification of automatic line sequence.

The network management and the third layer switch can support DHCP and BOOTP two protocols to obtain the IP address required by network management. These network management switches and three-tier switches support TFTP or FTP protocols, and many switches also support downloading software using the Xmodem protocol.
