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 - View which interface is in
activemode:~]#
enp1s0 is thecat /sys/class/net/bond0/bonding/active_slaveenp1s0activeport interface. - Set the
activeport interface down:~]#
ip link set enp1s0 down - Check if the
backupinterface is up:~]#
enp2s0 is now thecat /sys/class/net/bond0/bonding/active_slaveenp2s0activeport interface. - Check if you can still ping the destination IP from the bond interface:
~]#
ping -I bond0 DSTADDR
