1. 调整前查看SW vlan 
# dis vlan

2. 修改0/0/5 口vlan
# interface 25GE 0/0/5    # 进入0/0/5 口

#
return

3. 修改0/0/5 口 vlan 为vlan 1188
[BJS2-B05-SW02-25GE0/0/5]port default vlan 1188 
[BJS2-B05-SW02-25GE0/0/5]dis th

#
return

4. 修改后再次查看SW vlan

1189 common           

[BJS2-B05-SW02-25GE0/0/5]quit    # 退出vlan

2.2 调整辅测端交换机vlanif

复制代码 
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

复制代码 
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

复制代码 
e

3. SW(主测端)调整

3.1 调整主测端交换机vlanif

复制代码 
#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

复制代码 
1. 添加route 前查看

2. 添加route 
#  route add -net <三层环境vlanif 网段>/24 gw <本机SW 口所在vlanif IP>
e.g:  route add -net 33.33.33.0/24 gw 11.11.11.118


[root@localhost wangkatool]# route add -net 33.33.33.0/24 gw 11.11.11.118
