Core-level switches perform the main function of distributing network traffic on an object between WAN and network segments, such as Wi-Fi, video surveillance, workstations, IPTV, and so on. Since they are the most critical node of the network, the design of such devices is focused on fault tolerance, and the switches themselves have the function of combining into a stack, so that if one of the switches still fails, your network continues to function during replacement. Zyxel offers gigabit switches of the xgs4600 series of Layer 3 class, which are designed for use as root devices in networks of small hotels, offices and business centers.
In the XGS4600 model range, there are three switch variants that differ in the number and type of downlink interfaces:
|Total number of ports||32||32||52|
|Gigabit combo (SFP/RJ-45)||4||4||0|
|Switching performance (Gbps)||136||136||176|
|Packet forwarding speed (Mpps)||101.1||101.1||130.9|
|The packet buffer, MB||4||4||4|
Obviously, models with Gigabit SFP interfaces are designed for building networks over large areas where optics are used as the transmission medium, and the XGS4600-32 is a more “office” option.
Each of the switches has 4 SFP + slots with a speed of 10 Gbit / s for uplink connection, connection to server racks, or stacking. At the same time, each of the models has a full-fledged non-blocking switching matrix that allows you to simultaneously use the performance of all ports in duplex mode (136 Gbit/s for 32-port and 176 Gbit/s for 52-port models). For network packets, there is a fairly large buffer of 4 MB, and the amount of RAM is 1 GB.
Immediately I want to note that connecting to server racks in this particular case, we consider it more like just an opportunity to give a 10-GB link for some storage installed for backups. There are no file Protocol traffic prioritization functions in the xgs4600 series switches (if you need them, look towards the XS3800). this model is based on Layer 3 and fault tolerance. Let’s start with it.
