When a client device designates this switch as a DNS server, the client will attempt to resolve host names into IP addresses by forwarding DNS queries to the switch, and waiting for a response. You can manually configure entries in the DNS table used for mapping domain names to IP addresses, configure default domain names, or specify one or more name servers to use for domain name to address translation. 3-166 Configuring Domain Name Service 3 Configuring General DNS Server Parameters Command Usage · To enable DNS service on this switch, first configure one or more name servers, and then enable domain lookup status. · To append domain names to incomplete host names received from a DNS client (i. e. , not formatted with dotted notation), you can specify a default domain name or a list of domain names to be tried in sequential order. · 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) · 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. 3-167 3 Configuring the Switch Web ­ Select DNS, General Configuration. Set the default domain name or list of domain names, specify one or more name servers to use to use for address resolution, enable domain lookup status, and click Apply. Figure 3-106. DNS Configuration CLI - This example sets a default domain name and a domain list. However, remember that if a domain list is specified, the default domain name is not used.

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. [. . . ] Formerly called Group Address Registration Protocol. Generic Multicast Registration Protocol (GMRP) GMRP allows network devices to register end stations with multicast groups. GMRP requires that any participating network devices or end stations comply with the IEEE 802. 1p standard. Group Attribute Registration Protocol (GARP) See Generic Attribute Registration Protocol. IEEE 802. 1D Specifies a general method for the operation of MAC bridges, including the Spanning Tree Protocol. IEEE 802. 1Q VLAN Tagging--Defines Ethernet frame tags which carry VLAN information. 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. 1s An IEEE standard for the Multiple Spanning Tree Protocol (MSTP) which provides independent spanning trees for VLAN groups. 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. Glossary-2 Glossary 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. 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.
