263 GS752TP , GS728TP , and GS728TPP Gigabit Smart Switches Also the confirmed action on this flow is to send the packets with a committed rate of 10,000 Kbps and burst size of 128 KB. Packets that violate the committed rate and burst size are dropped. 802.1x Local area networks (LANs) are often deployed in environments that permit unauthorized dev[...]

264 GS752TP , GS728TP , and GS728TPP Gigabit Smart Switches Access control is achieved by enforcing authentication of supplicants that are attached to a controlled ports of the authenticator . The result of the authentication process determines whether the supplicant is authorized to access services on that controlled port. A port access entity (P [...]

When the Port Control setting is Auto, the authenticator P AE sets the controlled port mode. 3. In the Guest VLAN field for ports g1–g8, enter 150 to assign these ports to the guest VLAN. Y ou can configure more settings t[...]

266 GS752TP , GS728TP , and GS728TPP Gigabit Smart Switches MSTP Spanning T ree Protocol (STP) runs on bridged networks to help eliminate loops. If a bridge loop occurs, the network can become flooded with traffic. IEEE 802.1s Multiple Spanning T ree Protocol (MSTP) supports multiple instances of spanning tree to efficiently channel VLAN traffic ov[...]

267 GS752TP , GS728TP , and GS728TPP Gigabit Smart Switches receive and transmit MSTP BPDUs. The MST configuration identifier has the following components: 1. Configuration identifier format selector 2. Configuration name 3. Configuration revision level 4. Configuration digest: 16-byte signature of type HMAC-MD5 created from the MST Configuration t[...]

268 GS752TP , GS728TP , and GS728TPP Gigabit Smart Switches In this example, ports g1–g5 are connected to host stations, so those links are not subject to network loops.

In the CST Port Configuration screen, select ports g1–g8 and select Enable from the STP Status list. For more information, see CST Port Configuration on page 96. 6. Click APPL Y . 7. Select ports g1–g5 (edge ports), and select [...]

270 GS752TP , GS728TP , and GS728TPP Gigabit Smart Switches Configure VLAN R outing with Static Route VLAN R outing Overview VLANs divide broadcast domains in a LAN environment. Whenever hosts in one VLAN need to communicate with hosts in another VLAN, the traffic must be routed between them. This is known as inter-VLAN routing. On NETGEAR switches[...]
