Monitoring the ARP Running Status

Monitoring the ARP Running Status

Context

Monitoring the ARP running status includes checking ARP mapping entries, strict ARP entry learning, ARP packet statistics, ARP packet processing rate, and maximum number of ARP entries learnt by an interface.

Procedure

  • Run the display arp interface interface-type interface-number command in any view to check the ARP running status on a specified interface.
  • Run the display arp [ network network-address [ network-mask | mask-length ] ] [ dynamic | static ] command in any view to check the ARP running status of a specified slot.
  • Run the display arp vpn-instance vpn-instance-name [ dynamic | static ] command in any view to check ARP mapping entries of a specified VPN instance.
  • Run the display arp vlan vlan-id interface interface-type interface-number command in any view to check ARP mapping entries of a specified VLAN.
  • Run the display arp statistics [ interface interface-type interface-number ] command in any view to check ARP entry statistics.
  • Run the display arp track command in any view to check changes of outbound interfaces in ARP entries learned by a VLANIF interface.
  • Run the display arp packet statistics [ interface [ interface-type interface-number ] ] command in any view to check ARP packet statistics.
  • Run the display arp l2-proxy vlan vlan-id [ ip ip-address | conflict user ] command in any view to check Layer 2 ARP proxy entries of a specified VLAN.

    NOTE:
    The CE6880EI does not support this command.

  • Run the display arp fast-reply statistics [ interface interface-type interface-number | ip ip-address [ vpn-instance vpn-instance-name ] ] command in any view to check statistics on fast ARP reply packets.
  • Run the display arp forwarding-status [ vpn-instance vpn-instance-name | all-vpn-instance ] [ interface interface-type interface-number ] command in any view to check whether ARP entries learned by an interface are delivered and ARP entry statistics.

    NOTE:

    The CE6880EI does not support this command.
