IP Commands

IP Commands (Table) The commands described in this chapter are listed in the table below.

This chapter describes the commands used to configure Ethernet and InfiniBand Internet Protocol connections. The first part of this chapter contains tables that list each IP command and cross-references command descriptions. The second part is comprised of descriptions of the commands in alphabetical order.

•“arp ib”

•“clear ib arp-cache”

•“default ip ip-over-ib-mtu”

•“ip domain-name”

•“ip ip-over-ib-mtu”

•“ip name-server-one”

•“ip name-server-two”

•“ip route”

Table B-38 IP Commands

Command	Keyword	Description
arp ib		Assigns static ARP addresses to InfiniBand interface ports.
clear ib arp-cache		Removes accumulated IPoIB addresses from the ARP routing table.
default ip ip-over-ib mtu		Resets the maximum size of the payload of IP-over-IB traffic back to the
		default size.
exit		Exits the current mode for the previous mode, or the user-execute mode.
		See “exit” (page 197)
help		Describes the types of online help information available. See “help”
		(page 199)
history		Lists all the commands executed during the current CLI session. See
		“history” (page 199)
ip domain-name		Configures the network DNS domain for the system chassis.
ip ip-over-ib-mtu		Sets the Maximum Transmission Unit (MTU) of the packet or frame
		payload of IP-over-IB traffic along a path from the source to its
		destination.
ip name-server-one		Specifies the IP address of the primary DNS server.
ip name-server-two		Specifies the IP address of the backup DNS server.
ip route		Defines static routes to remote hosts or networks for IP packet
		forwarding.
name		Assigns names to interface gateways for easier tracking (some gateway
		functions are not supported by HP InfiniBand).

arp ib

Synopsis: The arp ib command is used to statically map an IP address to the Global ID (GID) of an InfiniBand host running IPoIB on the local network.

Syntax: arp ib ip gid [:ext] qpn qpn slot#/port#

no arp ib ip port#/slot#

The syntax is described in the table below:
