适用场景

  • ONTAP 9
  • Arista交换机对

问题解答

  • 示例:
netapp01::*> arp active-entry show -node netapp01_01 -vserver netapp -mac aa:bb:cc:dd:ee:ff (network arp active-entry show) Node: netapp01_01 Vserver: netapp Subnet Group: 0.0.0.0/0 Remote IP Address MAC Address Port ----------------- ----------------- ------- 172.16.100.10 aa:bb:cc:dd:ee:ff e2a 172.16.100.20 aa:bb:cc:dd:ee:ff e2b 172.16.100.40 aa:bb:cc:dd:ee:ff e2c 172.16.100.60 aa:bb:cc:dd:ee:ff e2d 172.16.100.80 aa:bb:cc:dd:ee:ff e2e
  • 如果在Arista交换机中配置了VARP、则会出现这种情况。
  • 当路由器为虚拟子网中的IP地址发送ARP请求时、ARP请求将使用虚拟IP地址作为源IP地址、而使用虚拟MAC地址作为ARP标头中的源MAC地址。
