回答

  • 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
  • これは、AristaスイッチにVARPが設定されている場合に想定されています。
  • ルータが仮想サブネット内のIPアドレスのARP要求を送信すると、ARP要求はその仮想IPアドレスを送信元IPアドレスとして使用し、仮想MACアドレスをARPヘッダー内の送信元MACアドレスとして使用します。
