2.2 调整辅测端交换机vlanif

1. 查看vlan 1188 的 Vlanif info [BJS2-B05-SW02]interface Vlanif 1188 [BJS2-B05-SW02-Vlanif1188]dis th # interface Vlanif1188 # return [BJS2-B05-SW02-Vlanif1188] 2. 配置Vlanif IP [BJS2-B05-SW02-Vlanif1188]ip address 33.33.33.119 255.255.255.0 [BJS2-B05-SW02-Vlanif1188]dis th # interface Vlanif1188 ip address 33.33.33.119 255.255.255.0 # return

2.3 调整辅测端mac0 口IP

辅测端mac0 口IP 应该与 mac0 口连接的SW 口所在的vlanIf IP 同网段， 所以删除辅测端mac0 口IP，并重新配置辅测端mac0 口IP 1. 修改mac0 iP 前查看 [root@localhost network-scripts]# ifconfig swift150f0 swift150f0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 11.11.11.219 netmask 255.255.255.0 broadcast 11.11.11.255 ether 74:3e:39:10:02:57 txqueuelen 1000 (Ethernet) RX packets 13444487183 bytes 11717176270925 (10.6 TiB) RX errors 0 dropped 105467 overruns 148176 frame 0 TX packets 6664048343 bytes 3725548201653 (3.3 TiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 [root@localhost network-scripts]# 2. 修改mac0 IP [root@localhost network-scripts]# cat /etc/sysconfig/network-scripts/ifcfg-swift150f0 HWADDR=74:3E:39:10:02:57 TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=none IPADDR=33.33.33.219 # 修改IP为33.33.33.219 PREFIX=24 DEFROUTE=yes IPV4_FAILURE_FATAL=no IPV4_DNS_PRIORITY=100 IPV6INIT=no NAME=swift150f0 UUID=a8bd1d0a-be3d-4fc2-a3fb-fe027e17e7bd DEVICE=swift150f0 ONBOOT=yes [root@localhost network-scripts]# 3. 修改后使iPv4 生效 [root@localhost network-scripts]# systemctl restart network [root@localhost network-scripts]# ifconfig swift150f0 swift150f0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 33.33.33.219 netmask 255.255.255.0 broadcast 33.33.33.255 ether 74:3e:39:10:02:57 txqueuelen 1000 (Ethernet) RX packets 13444487241 bytes 11717176277760 (10.6 TiB) RX errors 0 dropped 105488 overruns 148176 frame 0 TX packets 6664048344 bytes 3725548201713 (3.3 TiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 [root@localhost network-scripts]#

2.4 辅测添加route配置

3. SW(主测端)调整

3.1 调整主测端交换机vlanif

#因为mac0 连接SW 0/0/1 口，所在vlan:1021 1. 查看vlan 1021 的 Vlanif info [BJS2-B05-SW02-Vlanif1188]interface Vlanif 1021 [BJS2-B05-SW02-Vlanif1021]dis th # interface Vlanif1021 # return [BJS2-B05-SW02-Vlanif1021 2. 配置Vlanif IP [BJS2-B05-SW02-Vlanif1021]ip address 11.11.11.118 24 [BJS2-B05-SW02-Vlanif1021]dis th # interface Vlanif1021 ip address 11.11.11.118 255.255.255.0 # return [BJS2-B05-SW02-Vlanif1021]

3.2主测添加route配置
