Variable definitions

Use the data in the following table to use the show ip arp command.


Variable	Value
A.B.C.D	Specifies the IP address of a network.
{slot/port[/sub-port][-slot/port[/sub-port]][,...]}	Identifies the slot and port in one of the following formats: a single slot and port (slot/port), a range of slots and ports (slot/port-slot/port), or a series of slots and ports (slot/port,slot/port,slot/port). If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.
interface	Displays ARP interface configuration information.
spbm-tunnel-as-mac	Displays the remote host name in the TUNNEL column for the SPBM ARP entry.
-s	Specifies a subnet. You must indicate the IP address followed by the subnet mask expressed as <A.B.C.D> <A.B.C.D>.
vlan `<1-4059>`	Displays ARP entries for a particular VLAN ID. Specifies the VLAN ID in the range of 1 to 4059. By default, VLAN IDs 1 to 4059 are configurable and the system reserves VLAN IDs 4060 to 4094 for internal use. On switches that support the vrf-scaling and spbm-config-mode boot configuration flags, if you enable these flags, the system also reserves VLAN IDs 3500 to 3998. VLAN ID 1 is the default VLAN and you cannot create or delete VLAN ID 1.
vrf `WORD<1–16>`	Specifies a VRF name expressed as text from 1 to 16 characters in length. The total number of ARPs listed in the summary line of the show ip arp output represents the total number of ARPs on the chassis, including all VRFs (which includes the Management Router VRF).
vrfids `WORD<0–512>`	Specifies a range of VRFIDs as text from 0 to 512 characters in length. The total number of ARPs listed in the summary line of the show ip arp output represents the total number of ARPs on the chassis, including all VRFs (which includes the Management Router VRF).

Use the data in the following table to help you understand the show ip arp interface command output.


Variable	Value
PORT_NUM	Indicates the port number.
DOPROXY	Indicates if ARP proxy responses are enabled or disabled on the specified interface.
DORESP	Indicates if the sending of ARP responses is enabled or disabled on the specified interface.

Use the data in the following table to help you understand the show ip arp interface vlan command output.


Variable	Value
VLAN_ID	Indicates the VLAN ID.
DOPROXY	Indicates if ARP proxy responses are enabled or disabled on the specified interface.
DORESP	Indicates if the sending of ARP responses is enabled or disabled on the specified interface.
