I have configured the bonding with mode 1 :bond-mode active-backup.

 ln@ubuntu:~$ cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

auto ens33
iface ens33 inet manual
bond-master bond0
bond-primary ens33

#eth2 configuration
auto ens38
iface ens38 inet manual
bond-master bond0

# Bonding eth1 & eth2 to create bond0 NIC
auto bond0
iface bond0 inet static
bond-mode active-backup
bond-miimon 100
bond-updelay 500
bond-slaves none

ens33 is bond-primary. when ens33 is unavailable , ens38 start work , then ens33 is available , the network will not work . ping will failed.

From icmp_seq=3 Destination Host Unreachable

how to resolve this?
