1.5 Function Descriptions 1.5.1 LACP Trunking Function The switch provides a trunking function, which is compliant with 802.3ad standard. 802.3ad is a specification from IEEE that allows us to bundle several physical port links together to form one logical port , called a trunk between two devices. It supports Link Aggregation Control Protocol (LACP). IEEE 802.3ad trunking also allows redundant connections between devices to be combined for m ore aggregate bandwidth between devices suppo

1.5.2 IP Multicast Function Internet Protocol (IP) multicast is a bandwidth-conserving technology that reduces traffic by simultaneously delivering a single stream of information to thousands of corporate recipients and homes. Applications that take advantage of multicast include video conference, corporate communications, distance learning, and distribution of software, stock quotes, and news. IP Multicast delivers source traffic to multiple receivers without adding any additional burden

IGMP Internet Group Management Protocol (IGMP) is used to dynamically register individual hosts in a multicast group on a particular LAN. Hosts identify group memberships by sending IGMP messages to their local multicast router. Under IGMP, routers listen to IGMP messages and periodically send out queries to discover which groups are active or inactive on a particular subnet. RFC 2236 defines the specification for IGMP Version 2. There are four types of IGMP messages: _ Membership que

IGMP Snooping IGMP snooping requires the LAN switch to examine, or snoop, some Layer 3 information in the IGMP packets sent between the hosts and the router. When the switch hears the IGMP host report from a host for a particular multicast group, the switch adds the host's port number to the associated multicast table entry. When the switch hears the IGMP leave group message from a host, it removes the host's port from the table entry. Multicast Forwarding In multicast routing, the sou

1.5.4 Static MAC Address The switch provides Static MAC Address setup function. The static MAC addresses are the MAC addresses which are setup by LAN administrators and are not learned by the switch automatically. The static addresses are stored and referred in switch MAC address table permanently regardless of whether the MAC addresses are physically disconnected to the switch. Applying this function with port security function allows LAN administrator to build a protection mechanism

1.5.6 VLAN Function Virtual LANs (VLANs) can be viewed as a group of devices on different physical LAN segments which can communicate with each other as if they were all on the same physical LAN segment. It can create a network that is independent of physical location and group users into logical workgroups. The benefits are: _ Confine broadcast traffic and Increased performance _ Improved manageability _ Network tuning and simplification of software configurations _ Physical topology

1.5.6.2 IEEE 802.1Q VLAN (Tag-based VLAN) Tag-based VLAN is an IEEE 802.1Q specification standard. Therefore, it is possible to create a VLAN across devices from different venders. IEEE 802.1Q VLAN uses a technique to insert a tag into the Ethernet frames. Tag contains a VLAN Identifier (VID) that indicates the VLAN numbers. The switch can classify each received packet as belonging to one and only one VLAN. If the received packet is VLAN-tagged, the packet is classified as belonging to t

To provide path redundancy, Spanning-Tree Protocol defines a tree that spans all switches in an extended network. Spanning-Tree Protocol forces certain redundant data paths into a standby (blocked) state. If one network segment in the Spanning-Tree Protocol becomes unreachable, or if Spanning-Tree Protocol costs change, the spanning-tree algorithm re-configures the spanning-tree topology and reestablishes the link by activating the standby path. Spanning-Tree Protocol operation is tra
