NEC IXシリーズにIPv4/IPv6アドレスを設定する方法について説明します。また、IXシリーズにおけるデバイス番号、インターフェース番号の概念について説明します。
設定まとめ
コマンド一覧
IPアドレス設定に関するコマンド一覧は以下の通りです。
Router(config)# interface GigaEthernet0.X Router(config-GigaEthernet0.X)# encapsulation dot1q <vlan_id> Router(config-GigaEthernet0.X)# ip address <addr>/<mask> Router(config-GigaEthernet0.X)# ipv6 address <addr>/<mask> Router(config-GigaEthernet0.X)# no shutdown Router(config)# device GigaEthernet2 Router(config-GigaEthernet2)# vlan-group <group_num> port <port_num> [ <port_num> ... ] Router(config)# interface GigaEthernet2:X.Y Router(config-GigaEthernet2:X.Y)# encapsulation dot1q <vlan_id> Router(config-GigaEthernet2:X.Y)# ip address <addr>/<mask> Router(config-GigaEthernet2:X.Y)# ipv6 address <addr>/<mask> Router(config-GigaEthernet2:X.Y)# no shutdown
インターフェースの指定
以下のようなコマンドを用いて、インターフェースコンフィグモードに入ります。Xはデバイス番号を表しています。
Router(config)# interface GigaEthernetX.0 Router(config-GigaEthernetX.0)#
IPアドレスの設定
以下のようなコマンドを用いて、IPv4アドレス, IPv6アドレスを設定する事ができます。
Router(config)# interface GigaEthernetX.0 Router(config-GigaEthernetX.0)# ip address <addr>/<mask> Router(config-GigaEthernetX.0)# ipv6 address <addr>/<mask>
インターフェースの有効化
WAN側の初期設定は”administratively down”状態です。WAN側の通信をするには”no shut”コマンドが必要になります。
Router(config)# interface GigaEthernetX.0 Router(config-GigaEthernetX.0)# no shutdown

初期設定
IX2015は工場出荷時の状態で動作確認をします。工場出荷時の初期設定は以下の通りです。
動作確認 (1) IPv4 IPv6アドレスの設定
工場出荷時のIPアドレス設定は以下の通りです。
interface GigaEthernet1.0 ip address 192.168.1.254/24 no shutdown
以下のようなコマンドを実行し、IPv4アドレスとIPv6アドレスを設定します。
interface GigaEthernet1.0 ip address 192.168.1.254/24 ipv6 address 2001:1::254/64 no shutdown ! interface GigaEthernet0.0 ip address 200.0.0.254/24 ipv6 address 2001:200::254/64 no shutdown
動作確認 (2) 設定の表示
interfaceのup/downを確認するには、”show interface brief”が便利です。
Router# show interfaces brief Interface GigaEthernet0.0 is up IPv4 subsystem connected, physical layer is up, 0:03:20 ARP subsystem connected, physical layer is up, 0:03:20 IPv6 subsystem connected, physical layer is up, 0:03:20 Interface GigaEthernet1.0 is up IPv4 subsystem connected, physical layer is up, 0:06:22 ARP subsystem connected, physical layer is up, 0:41:08 IPv6 subsystem connected, physical layer is up, 0:06:22 Interface Null0.0 is up IPv4 subsystem connected, physical layer is up, 0:41:17 IPv6 subsystem connected, physical layer is up, 0:41:17 Interface Loopback0.0 is up IPv6 subsystem connected, physical layer is up, 0:41:17
IPv4アドレス IPv6アドレスを確認するには、”show ip interface”, “show ipv6 interface”を使って下さい。cisco機のように”show ip int bri”や”| include”は使えません。
