Commands Reference, Volume 1

Displays all of the current ARP entries. Use the crash command to look at KMEM or UMUnix variables. Specify the -a /dev/kmem flag to display ARP information for kernel memory. The 'n' modifier causes hostname lookups to be suppressed.

Used as { -t atm HostName | -a [ n ] [ /dev/kmem ] [ pvc | svc ] }

The pvc specification will display only ATM PVC (Permanent Virtual Circuits) types of virtual circuits, svc specification will display only ATM SVC (Switched Virtual Circuits) types of virtual circuits. If the pvc | svc parameter is omitted, all ATM virtual circuits will be displayed.

Deletes an entry for the host specified by the HostName variable if the user has root user authority.

Used as -t atm -d pvc vpi:vci if ifName

Deletes a PVC ARP entry by specifying vpi:vci rather than hostname. The vpi:vci variables specify the virtual circuit that is to be deleted. The ifname variable specifies the name of the ATM interface on which the virtual circuit is to be deleted.

where

Type

Specifies the type of hardware address. If the address type is specified when invoking arp from the command line, it should not be specified in the file entries. Otherwise it should be specified in each file entry. Valid hardware address types are:

• ether for an Ethernet interface
• 802.3 for an 802.3 interface
• fddi for a Fiber Distributed Data interface
• 802.5 for a Token-Ring interface

HostName

Specifies the remote host.

AdapterAddress

Specifies the hardware address of the adapter for this host as 6 hexadecimal bytes separated by colons. Use the netstat -v command to display the local hardware address.

Route

Specifies the route for a Token-Ring interface or Fiber Distributed Data Interface (FDDI) as defined in the Token-Ring or FDDI header.

temp

Specifies that this ARP table entry is temporary. The table entry is permanent if this argument is omitted.

pub

Specifies that this table entry is to be published, and that this system will act as an ARP server responding to requests for HostName, even though the host address is not its own.

Note: The -f flag is not supported for ATM.

Creates an ARP entry of the type specified by the Type variable for the host specified by the HostName variable with the adapter address specified by the AdapterAddress variable. The adapter address is given as 6 hexadecimal bytes separated by colons. The line must be in the following format:

Type HostName AdapterAddress [Route] [temp] [pub]

where the Type, HostName, AdapterAddress, Route, temp, and pub parameters have the same purpose and definitions as the parameters for the -f flag.

Used as -t atm -s Type HostName AdapterAddress [ temp ]

Creates a SVC type of ARP entry for the remote host, specified by the HostName variable, with the ATM address specified by the ATMAddress variable. The ATM address is given as 20 hexadecimal bytes separated by colons. Creation of this entry causes this IP station to not use ARP server mechanism to resolve IP addresses.

Used as -t atm -s Type pvc vpi:vci { HostName | if ifName } [ no-llc ] [ no-arp ] [ temp ]

Creates a PVC type of ARP entry for the remote host, specified by the HostName variable, with the PVC specified by the vpi:vci. Either destination Hostname or the local ifname needs to be specified. The no-llc flag is used to indicate that LLC/SNAP encapsulation will not be used on this virtual circuit, in this case, the destination Hostname needs to be specified. The no-arp flag is used to indicate that ARP protocol will not be used on this virtual circuit, in this case, the destination Hostname needs to be specified.

The temp parameter specifies that this ARP table entry is temporary, the table entry is permanent if this argument is omitted.

• et for IEEE 802.3 Ethernet (inet, xns)
• tr for Token-Ring (inet, xns)
• xt for X.25 (inet)
• sl for serial line IP (inet)
• lo for loopback (inet)
• op for serial (inet)

The -t atm flag is required for the following interfaces:

• at for ATM
