Advanced network Configuration

Advanced Network configuration:
1. Configure Network bridging
Bridging action enables your virtual machine and real machine to use the same network device
#brctl Show
#brctl Delif br0 eth0
#brctl addif br0 eth0
#vim/etc/sysconfig/network-scripts/ifcfg-eth0
Device=eth0
Onboot=yes
Bootproto=none
Peerdns=no
Bridge=br0
Vim/etc/sysconfig/network-scripts/ifcfg-br0
Device=br0
Onboot=yes
Bootproto=none
ipaddr=172.25.254.100
netmask=255.255.255.0
Peerdns=no
Type=bridge
#systemctl Restart Network//start twice
Brctl
# # # Bridge Management commands
–show # # # Display
–ADDBR # # # Add a bridge
–DELBR # # # Delete a network bridge
–ADDIF # # # Add a bridge connection
–delif # # # Delete a bridge connection
2,bond Network Configuration
(1), using the command configuration is temporary configuration
NMCLI Connect Add type Bond con-name BOND0 ifname bond0 mode active-backup ip4 172.25.254.100/24 gw4 172.25.254.250//build bindings Interface Bond0
NMCLI connection Add type Bond-slave con-name eth0 ifname eth0 Master bond0//Establish Slave interface eth0
NMCLI connection Add type Bond-slave con-name eth1 ifname eth1 Master bond0//Establish Slave interface eth1
Monitoring Watch-n 1/proc/net/bonding/bond0
Need to turn off #systemctl stop NetworkManager
troubleshooting, sometimes unsuccessful, requires NMCLI connection Show/delete/add
(2),
To establish a binding interface bond0 configuration file:
#vim/etc/sysconfig/network-scripts/ifcfg-bond0
Device=bond0
Name=bond0
Type=bond
Bootproto=none
ipaddr=172.25.254.100
Prefix0=24
Onboot=yes
bonding_opts= "Mode=1 miimon=50"
#vim/etc/sysconfig/network-scripts/ifcfg-eth0
Type=ethernet
Name=eth0
Device=eth0
Onboot=yes
Master=bond0
Slave=yes
#############
#vim/etc/sysconfig/network-scripts/ifcfg-eth1
Type=ethernet
Name=eth1
Device=eth1
Onboot=yes
Master=bond0
Slave=yes
#vim/etc/modprobe.d/bonding.conf
Alias Bond0 Bonding
Systemctl Restart Network
Cat/proc/net/bonding/bond0
View bonding Status
Bond supports two NICs by default, and team supports 8 NICs by default
3. Configure the Team network
Configuring the Team Interface
#nmcli connection Add type team con-name TEAM0 ifname team0 config ' {"runner": {"name": "Activebackup"}} ' Ip4 172.25.254.1 XX gw4 172.25.254.250
#nmcli connection Add con-name eth0 ifname eth0 type Team-slave Master TEAM0
#nmcli connection Add con-name eth1 ifname eth1 type Team-slave Master TEAM0
#systemctl Restart Network
#teamdctl Team0 State
#ifconfig eth0 Down
#teamdctl Team0 State
#ifconfig eth0 up
#teamdctl Team0 State
