Domain Name System configuration The Domain Name System (DNS) Configuration commands are used for defining the primary and secondary DNS servers on your local network, and for setting the default domain name served by the switch services. DNS parameters must be configured prior to using hostname parameters with the ping, traceroute, and tftp commands. The following table describes the Domain Name System (DNS) Configuration commands. Table 143 Domain Name System (DNS) Configuration commands Command [no] ip name-server [no] ip name-server [no] ip domain-name show ip dns Description Sets the IP address for your primary DNS server. Use dotted decimal notation. Command mode: Global configuration Sets the IP address for your secondary DNS server. If the primary DNS server fails, the configured secondary will be used instead. Enter the IP address using dotted decimal notation. Command mode: Global configuration Sets the default domain name used by the switch. For example: mycompany.com Command mode: Global configuration Displays the current Domain Name System (DNS) settings. Command mode: All except User EXEC Bootstrap Protocol Relay configuration Bootstrap Protocol (BOOTP) Relay is used to allow hosts to obtain their configurations from a Dynamic Host Configuration Protocol (DHCP) server. The BOOTP configuration enables the switch to forward a client request for an IP address to two DHCP/BOOTP servers with IP addresses that have been configured on the GbE2c Ethernet Blade switch. BOOTP relay is turned off by default. NOTE: BOOTP commands are available only on the GbE2c Layer 2/3 Ethernet Blade Switch. The following table describes the BOOTP Configuration commands. Table 144 BOOTP Configuration commands Command [no] ip bootp-relay server ip bootp-relay enable no ip bootp-relay enable show ip bootp-relay Description Sets the IP address of the first or second BOOTP server. Command mode: Global configuration Globally turns on BOOTP relay. Command mode: Global configuration Globally turns on BOOTP relay. Command mode: Global configuration Displays the current BOOTP relay configuration. Command mode: All Configuration Commands 125

Configuration Commands 125
Domain Name System configuration
The Domain Name System (DNS) Configuration commands are used for defining the primary and secondary DNS
servers on your local network, and for setting the default domain name served by the switch services. DNS
parameters must be configured prior to using hostname parameters with the
ping,
traceroute,
and
tftp
commands.
The following table describes the Domain Name System (DNS) Configuration commands.

Bootstrap Protocol Relay configuration
Bootstrap Protocol (BOOTP) Relay is used to allow hosts to obtain their configurations from a Dynamic Host
Configuration Protocol (DHCP) server. The BOOTP configuration enables the switch to forward a client request for an
IP address to two DHCP/BOOTP servers with IP addresses that have been configured on the GbE2c Ethernet Blade
switch.
BOOTP relay is turned off by default.
NOTE:
BOOTP commands are available only on the GbE2c Layer 2/3 Ethernet Blade Switch.
The following table describes the BOOTP Configuration commands.
