Disabling Next Hop or ARP Port Movement Syslog Message Generation

Whenever a port, on which a MAC address for an ARP is learned, is moved to a different port, a syslog message is generated by default.

This may cause Flooding of the syslog server or console with syslog messages may occur in certain deployments where next hop or ARP port movement occurs continuously. In such scenarios, the default behavior can be disabled and syslog messages can be prevented from being generated with every port movement for ARP entries using the no ip arp port-move-syslog command.

The status of the next hop or ARP port movement syslog message (enabled or disabled) can be viewed in the output of the show ip command.

The following example shows sample output of the show ip command in which the status of the next hop or ARP port movement syslog message (enabled) is displayed. 

device(config)# show ip 
  ttl: 64, arp-age: 10, bootp-relay-max-hops: 4
  router-id : 10.1.1.1
  enabled : BGP4  UDP-Broadcast-Forwarding  Source-Route  Load-Sharing  RARP  VSRP
  arp-port-move-syslog
  disabled: Route-Only  Directed-Broadcast-Forwarding  IRDP  Proxy-ARP  RIP  OSPF
  VRRP  VRRP-Extended  ICMP-Redirect  add-host-route-first

device(config)# no ip arp port-move-syslog 
device(config)# show ip
Global Settings
  ttl: 64, arp-age: 10, bootp-relay-max-hops: 4
  router-id : 10.1.1.1

  disabled: Route-Only  Directed-Broadcast-Forwarding  IRDP  Proxy-ARP  RIP  OSPF
  VRRP  VRRP-Extended  ICMP-Redirect  add-host-route-first arp-port-move-syslog

The following example shows sample output of the show ip command in which the status of the next hop or ARP port movement syslog message (disabled) is displayed. 

device(config)# no ip arp port-move-syslog 
device(config)# show ip
