There are three Trunk groups to be set; and there are default ports in each member. Checked "Enable" to use the trunk function, select the ports in each member to be trunk, and click "Apply" to activate the selected trunk group. 30 Figure 21. Trunk Settings Be sure that the selected trunk setting port must connect to the device with a same VLAN group. Mirror Setting Port Mirroring is a method of monitoring network traffic that forwards a copy of each incoming and/or outgoing packet from one port of a network switch to another port where the packet can be studied. It enables the manager to keep close track of switch performance and alter it if necessary. Configuring the port mirroring by assigning a source port from which to copy all packets and a sniffer port where those packets will be sent. The selection of the sniffer mode is as follow: TX (transmit) mode: this mode will duplicate the data transmit from the source port and forward to the sniffer port. RX (receive) mode: this mode will duplicate the data that send to the source and forward to the sniffer port. 31 Both (transmit and receive) mode: this mode will duplicate both the data transmit from and data that send to the source port, then it will forward to the sniffer port. Figure 22. Mirror setting 32 IEEE 802. 1P QoS Setting To set the Switch QoS base on IEEE 802. 1p, Figure 23. IEEE 802. 1P-based QoS setting Spanning Tree Setting This Switch supports the 802. 1d Spanning Tree Protocol. Every segment will have a single path to the root bridge. However, BPDU packets are sent more frequently - with every Hello packet. BPDU packets are sent even if a BPDU packet was not received. Therefore, each link between bridges is sensitive to the status of the link. Ultimately this difference results in faster detection of failed links, and thus faster topology adjustment. A draw-back of 802. 1d is this absence of immediate feedback from adjacent bridges. Figure 24. Spanning Tree Setting 33 STP Function: To selecting enable or disable STP function on the Switch. Bridge Priority: This value between 0 and 65535 to specify the priority for forwarding packets. The lower the value, the higher the priority. Bridge Max Age: This value may be set to ensure that old information does not endlessly circulate through redundant paths in the network, preventing the effective propagation of the new information. Set by the Root Bridge, this value will aid in determining that the Switch has spanning tree configuration values consistent with other devices on the bridged LAN.
