ether (Ethernet) netrom (AMPR NET/ROM)
Usage:
arp [-vn] [<HW>] [-i <if>] [-a] [<hostname>] <-Display ARP cache
arp [-v] [-i <if>] -d <host> [pub] <-Delete ARP entry
arp [-vnD] [<HW>] [-i <if>] -f [<filename>] <-Add entry from file
arp [-v] [<HW>] [-i <if>] -s <host> <hwaddr> [temp] <-Add entry
arp [-v] [<HW>] [-i <if>] -Ds <host> <if> [netmask <nm>] pub <-''-
-a display (all) hosts in alternative (BSD) style
-e display (all) hosts in default (Linux) style
-s, --set set a new ARP entry
-d, --delete delete a specified entry
-v, --verbose be verbose
-n, --numeric don't resolve names
-i, --device specify network interface (e.g. eth0)
-D, --use-device read <hwaddr> from given device
-A, -p, --protocol specify protocol family
-f, --file read new entries from file or from /etc/ethers
<HW>=Use '-H <hw>' to specify hardware address type. Default: ether
List of possible hardware types (which support ARP):
Options (11)
| Option | Description | Source |
|---|
-a | Use alternate BSD style output format (with no fixed columns). | help + man |
-e | Use default Linux style output format (with fixed columns). | help + man |
-s, --set | set a new ARP entry | help |
-d, --delete | delete a specified entry | help |
-v, --verbose | Tell the user what is going on by being verbose. | help + man |
-n, --numeric | shows numerical addresses instead of trying to determine symbolic host, port or user names. | help + man |
-i, --device If | specify network interface (e.g. eth0) | help + man |
-D, --use-device | Instead of a hw_addr, the given argument is the name of an interface. | help + man |
-A, -p, --protocol | specify protocol family | help |
-f, --file filename | Similar to the -s option, only this time the address info is taken from file filename. | help + man |
-H, --hw-type, -t type | When setting or reading the ARP cache, this optional parameter tells arp which class of entries it should check for. (in the manual page but not in --help) | man |
