show iparp

show iparp {ip_addr |mac | [{vlan} vlan_name | vlan vlan_list] | permanent} {port port {vr vr_name}

Description

Displays the IP Address Resolution Protocol (ARP) table. You can filter the display by IP address, MAC address, This command is available on the ExtremeSwitching X440-G2, X450-G2, X460-G2, X465, X590, X620, and X695 series switches., or permanent entries.

Syntax Description

ip_addr Specifies an IP address.
mac Specifies a MAC address.
vlan_name Specifies a VLAN name.
vlan_list Specifies a VLAN list of IDs.
permanent Specifies permanent entries.
port Show entries for a specific port.
port Show only entries for this port number.
vr_name Specifies a VR or VRF.

Default

Show all entries, except for proxy entries.

Usage Guidelines

Displays the IP ARP table, including:
  • IP address
  • MAC address
  • Aging timer value
  • VLAN name, VLAN ID and port number
  • Flags

If you do not specify a VR or VRF, the command applies to the current VR context.

The show output displays the following information:

ARP address check Whether IP ARP checking is enabled or disabled. IP ARP checking verifies if the ARP request‘s source address is in the receiving interface‘s subnet.
ARP refresh Whether ARP refresh is enabled or disabled. ARP refresh is performed when an ARP entry‘s age is three-fourths of the timeout value.
Dynamic entries The number of dynamic (learned ARP) entries in the table.
Pending entries The number of sent ARP requests that have not yet received a response.
Static entries The number of configured (static ARP) entries in the table.
Timeout Timeout value for a dynamic (learned) ARP entry.
ARP Global Settings
Max Entries Maximum number of ARP entries.
Max Pending Entries Maximum number of pending ARP entries.
Max Proxy Entries Maximum number of proxy ARP entries.

Example

The following example displays the IP ARP table for the current VR or VRF context:
