Ip name-server-one | HP UX 11i v2 Networking Software manual

Table B-41	Command Syntax Description (continued)
Command	Description
mtu	Enter the Maximum Transmission Unit (MTU) to apply. The MTU value may be 256, 512,
	1024, 2048, or 4096. MTU is specified in octets (8-bit bytes). Refer to Usage Guidelines for
	more information.
no	Sets the MTU to the default.

Command Modes: Global configuration (config) mode.

Privilege Level: Ethernet and InfiniBand read-write user.

Usage Guidelines: The maximum transmission unit is described in terms of payload size. TCP uses the MTU to determine the maximum payload allowed for every transmission. Too great a value can overwhelm routers and result in data retransmission. Too small a value results in degraded performance because there are more headers and acknowledgements required to transmit the same amount of data.

Examples:

HP-IB# configure

HP-IB(config)# ip ip-over-ib-mtu 4096

HP-IB(config)#

Defaults: The default ip-over-ib-mtu unit is 2048.

NOTE: Infiniband hosts cannot handle change in MTU.

Related Commands: “show ip” (page 168)

ip name-server-one

Synopsis: The ip name-server-onecommand specifies the IP address of the primary DNS server.

Syntax: ip name-server-one ip no ip name-server-one

The syntax is described in the table below:

Table B-42	Command Syntax Description
Command	Description
ip	Enter the main ip command.
name-server-oneSpecifies the IP address of the primary DNS server.
ip	Enter the IP address of the primary DNS server.
no	Use this keyword to return the primary DNS server to the default address.

Command Modes: Global configuration (config) mode.

Privilege Level: Ethernet and InfiniBand read-write user.

Usage Guidelines: Configure this parameter in order to support name resolution when specifying other devices and hosts by name.

Examples:

HP-IB# configure

HP-IB(config)# ip name-server-one 10.3.103.22

Defaults: The default is an empty string.

Related Commands: “ip name-server-two” (page 181) “show host” (page 141)
