The switches provide Port Control Rate Limit, including Ingress and Egress
Rate Limit.
4. VLAN Setting
A Virtual, commonly known as a VLAN, is used to create independent logical
networks within a physical network. Several VLANs may co-exist within such a
network. VLAN can effectively reduce the scope of Broadcast, and it’s
convenient to manage network through logical network segment (for example,
company’s department) that cannot conduct data exchange and is separated.
As a matter of fact, if you add a router between different virtual network
segments, they can conduct data exchange through router.
Managed switches support IEEE802.1Q VLAN. There are three types of VLAN
port settings:
Access Port:
The port connects to a single device that is not tagged. The user must
define the default port PVID that assigns which VLAN the device belongs to.
Once the ingress packet of this Access Port egresses to another Trunk Port
(the port needs all packets to carry tag information), the switch will insert
this PVID into this packet so the next 802.1Q VLAN switch can recognize it.
Trunk Port:
The port connects to a LAN that consists of untagged devices, tagged
devices and/or switches and hubs. In general, the traffic of the Trunk Port
