Switches that support clustering can be grouped together regardless of physical location or switch type, as long as they are connected to the same local network. A switch cluster has a "Commander" unit that is used to manage all other "Member" switches in the cluster. The management station can use both the web interface and Telnet to communicate directly while the Commander throught its IP address, and the Commander manages Member switches using cluster "internal" IP addresses. There can be up to 16 Member switches in one cluster. Cluster switches are limited to within a single IP subnet. 3-194 Switch Clustering Once a switch has been configured to be a cluster Commander, it automatically discovers other cluster-enabled switches in the network. These "Candidate" switches only become cluster Members when manually selected by the administrator through the management station. 3 After the Commander and Members have been configured, any switch in the cluster can be managed from the web interface by choosing the Member ID from the Cluster drop-down menu. From the Commander CLI prompt, use the "rcommand" command (see 4-240) to connect to the Member switch. Figure 3-122 Cluster Member Choice Cluster Configuration To create a switch cluster, first be sure that clustering is enabled on the switch (the default is enabled), then set the switch as a Cluster Commander. Set a Cluster IP Pool that does not conflict with the network IP subnet. Cluster IP addresses are assigned to switches when they become Members and are used for communication between Member switches and the Commander. Command Attributes · Cluster Status ­ Enables or disables clustering on the switch. · Cluster Commander ­ Enables or disables the switch as a cluster Commander. · Role ­ Indicates the current role of the switch in the cluster; either Commander, Member, or Candidate. · Cluster IP Pool ­ An "internal" IP address pool that is used to assign IP addresses to Member switches in the cluster. Internal cluster IP addresses are in the form 10. x. x. member-ID. Only the base IP address of the pool needs to be set since Member IDs can only be between 1 and 16. Note that you cannot change the cluster IP pool when the switch is currently in Commander mode. [. . . ] It allows switches to assign endstations to different virtual LANs, and defines a standard way for VLANs to communicate across switched networks. IEEE 802. 1p An IEEE standard for providing quality of service (QoS) in Ethernet networks. The standard uses packet tags that define up to eight traffic classes and allows switches to transmit packets based on the tagged priority value. IEEE 802. 1X Port Authentication controls access to the switch ports by requiring users to first enter a user ID and password for authentication. IEEE 802. 3ac Defines frame extensions for VLAN tagging. IEEE 802. 3x Defines Ethernet frame start/stop requests and timers used for flow control on full-duplex links. (Now incorporated in IEEE 802. 3-2002) Glossary-2 Glossary IGMP Snooping Listening to IGMP Query and IGMP Report packets transferred between IP Multicast Routers and IP Multicast host groups to identify IP Multicast group members. IGMP Query On each subnetwork, one IGMP-capable device will act as the querier -- that is, the device that asks all hosts to report on the IP multicast groups they wish to join or to which they already belong. The elected querier will be the device with the lowest IP address in the subnetwork. Internet Group Management Protocol (IGMP) A protocol through which hosts can register with their local router for multicast services. [. . . ]
