7.5. Verifying Network Configuration Bonding for Redundancy

Network redundancy is a process when devices are used for backup purposes to prevent or recover from a failure of a specific system. The following procedure describes how to verify the network configuration for bonding in redundancy:

Procedure

Ping the destination IP from the bond interface. For example:
```
ping -I bond0 DSTADDR
```
```
~]# ping -I bond0 DSTADDR
```
Copy to Clipboard Toggle word wrap
View which interface is in active mode:
```
~]# cat /sys/class/net/bond0/bonding/active_slave
enp1s0
```
```
~]# cat /sys/class/net/bond0/bonding/active_slave
enp1s0
```
Copy to Clipboard Toggle word wrap
enp1s0 is the active port interface.
Set the active port interface down:
```
ip link set enp1s0 down
```
```
~]# ip link set enp1s0 down
```
Copy to Clipboard Toggle word wrap
Check if the backup interface is up:
```
~]# cat /sys/class/net/bond0/bonding/active_slave
enp2s0
```
```
~]# cat /sys/class/net/bond0/bonding/active_slave
enp2s0
```
Copy to Clipboard Toggle word wrap
enp2s0 is now the active port interface.
Check if you can still ping the destination IP from the bond interface:
```
ping -I bond0 DSTADDR
```
```
~]# ping -I bond0 DSTADDR
```
Copy to Clipboard Toggle word wrap
