display arp slot

Function

The display arp slot command displays the Address Resolution Protocol (ARP) entries on an interface board.

Format

display arp slot slot-id [ network ip-address [ ip-mask | mask-length ] ] [ dynamic | static ]

display arp { network ip-address [ ip-mask | mask-length ] [ dynamic | static ] | dynamic | static }

Parameters

Parameter	Description	Value
network ip-address	Displays ARP entries based on the network ID expressed in dotted decimal notation.	The value is in dotted decimal notation.
ip-mask	Displays ARP entries based on the subnet mask of a specified network ID. The format of the subnet mask is X.X.X.X.	The value is in dotted decimal notation.
mask-length	Displays ARP entries based on the subnet mask length of a specified network ID.	The value ranges from 1 to 32
dynamic	Displays dynamic ARP entries.	-
static	Displays static ARP entries.	-
slot slot-id	Displays ARP entries of the board in a specified slot.	-

Usage Guidelines

Usage Scenario

To check ARP entries or locate ARP faults on an interface board, run the display arp slot command.

You cannot specify a slot ID to view ARP entries on centralized devices or distributed devices that do not have interface boards.

This command is supported only on physical systems (PSs).

Example

The actual command output varies according to the device. The command output here is only an example.

# Display ARP entries on the interface board in slot 1.

<HUAWEI> display arp slot 1

**Table 1** Description of the **display arp slot** command output
Item	Description
IP ADDRESS	IP address in an ARP entry.
MAC ADDRESS	MAC address in the ARP entry. When an IP packet triggers an ARP Miss message, the device generates a MAC address with the Incomplete flag based on the ARP Miss message.
INTERFACE	Type and number of the interface that has learned ARP entries.
VPN-INSTANCE	VPN instance name of an ARP entry.
EXPIRE(M)	Remaining lifetime of an ARP entry, in minutes.
TYPE	Type and slot ID of an ARP entry. The entry type contains 3 bits. The first bit can be any of the following: I: Interface, indicating an interface's ARP entry. D: Dynamic, indicating dynamic entries obtained using ARP messages. S: Static, indicating static ARP entries configured. R: Remote, indicating the ARP entry obtained through remote backup. RD: Redirect, indicating a redirected ARP entry. The second bit can only be F, indicating that the entry is reported to the routing module, the route to this IP address is calculated, and the entry is installed to the FIB.The entries that have not been reported to the routing module are displayed as "-". This flag does not exist for the ARP entries of the I type. The third bit indicates the slot ID of the interface board from which the entry is obtained.The third bit displays a hyphen (-) for ARP entries with the type as "I" or "S".
VLAN/CEVLAN	VLAN ID of an ARP entry.
PVC	Interface on which a PVC is configured and corresponding VPI/VCI.
Redirect	Number of redirected ARP entries.
Interface	Number of ARP entries for the local interface in the ARP table.
Total	Number of ARP entries in the ARP table.
Dynamic	Number of dynamic ARP entries in the ARP table.
Static	Number of static ARP entries in the ARP table.
Remote	Number of remote backup ARP entries.
