HP 12-Port 4X Fabric Copper Switch Commands
IP Commands
Appendix B
227
arp ib
Synopsis:
The arp ib command is used to statically map an IP address to the Global ID (GID) of a Fabric 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:
Command Modes:
Global-configuration mode.
Privilege Level:
HP Fabric read-write user.
Usage Guidelines:
The system supports dynamic ARP, so any IP host connected to an IB interface port may see or detect all the
other connected IPoIB and IP hosts. Connected IPoIB hosts are automatically detected by the subnet
manager, queried for their network information, and their information is added to the system routing table.
The routing table associates an IP address with a host GID (Global ID).
Static ARP addresses are assigned to Fabric interface ports to ensure these ports connect to the correct
network hosts.
An ARP table contains the currently available ARP records in the gateway. An ARP record may be
dynamically learned or statically created. For the most part, you may rely upon dynamic ARP addressing.
Dynamic ARP records may be deleted from the table after a period of time or updated if a host address-change
is detected (some gateway functions are not supported by HP Fabric Clustering System).
Examples:
HP-IB(config)# arp ib 10.2.0.50 gid fe:80:00:00:00:00:00:00:00:05:ad:00:00:00:16:97
qpn 2 115/0
Defaults:
This command has no defaults.
