[. . . ] If there is no domain list, the default domain name is used. If there is a domain list, the default domain name is not used. When an incomplete host name is received by the DNS server on this switch and a domain name list has been specified, the switch will work through the domain list, appending each domain name in the list to the host name, and checking with the specified name servers for a match. When more than one name server is specified, the servers are queried in the specified sequence until a response is received, or the end of the list is reached with no response. Note that if all name servers are deleted, DNS will automatically be disabled. · · · · Command Attributes · · Domain Lookup Status ­ Enables DNS host name-to-address translation. Default Domain Name* ­ Defines the default domain name appended to incomplete host names. (Range: 1-64 alphanumeric characters) Domain Name List* ­ Defines define a list of domain names that can be appended to incomplete host names. 1-5 names) · 3-207 CONFIGURING THE SWITCH · Name Server List ­ Specifies the address of one or more domain name servers to use for name-to-address resolution. (Range: 1-6 IP addresses) * Do not include the initial dot that separates the host name from the domain name. Web ­ Select DNS, General Configuration. Set the default domain name or list of domain names, specify one or more name servers to use for address resolution, enable domain lookup status, and click Apply.

Command Usage · Static entries may be used for local devices connected directly to the attached network, or for commonly used resources located elsewhere on the network. Servers or other network devices may support one or more connections via multiple IP addresses. If more than one IP address is associated with a host name in the static table or via information returned from a name server, a DNS client can try each address in succession, until it establishes a connection with the target device. · Command Attributes · Host Name ­ Name of a host device that is mapped to one or more IP addresses. (Range: 1-64 characters) 3-209 CONFIGURING THE SWITCH · · IP Address ­ Internet address(es) associated with a host name. (Range: 1-8 addresses) Alias ­ Displays the host names that are mapped to the same address(es) as a previously configured entry. Web ­ Select DNS, Static Host Table.

Type ­ This field includes CNAME which specifies the canonical or primary name for the owner, and ALIAS which specifies multiple domain names which are mapped to the same IP address as an existing entry. IP ­ The IP address associated with this record. TTL ­ The time to live reported by the name server.

Using the Command Line Interface Accessing the CLI When accessing the management interface for the switch over a direct connection to the server's console port, or via a Telnet connection, the switch can be managed by entering command keywords and parameters at the prompt. Using the switch's command-line interface (CLI) is very similar to entering commands on a UNIX system. Console Connection To access the switch through the console port, perform these steps: 1. [. . . ] 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 SMC6824MPE switch ports by requiring users to first enter a user ID and password for authentication. IEEE 802. 3ac Defines frame extensions for VLAN tagging. IEE 802. 3af (PoE) An IEEE standard for providing Power over Ethernet (PoE) capabilities. When Ethernet is passed over copper cable, two twisted pairs are used for data transfer, and two twisted pairs are unused. With PoE, power can either be passed over the two data pairs or over the two spare pairs. IEEE 802. 3x Defines Ethernet frame start/stop requests and timers used for flow control on full-duplex links. 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. Glossary-3 GLOSSARY 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.
