i connect GigabitEthernet1/0/48 set a ip 192.168.30.11/24 gw 192.168.30.1 with
a PC
I use 192.168.30.11 PC ping 192.168.30.10 is ok but
I ping 192.168.20.10 is time out
ping 192.168.25.10 time out too
so I start find solution until I no intention to restart centos ,then I ping
192.168.20.10 it ok .
then I think I Solve this. Life has taken my hand .after 20 min timeout again .
so I find solution again . I find the law of events.when I run systemctl
restart network . ping 192.168.20.10 it ok .and after 20 min it not work again
I run systemctl restart network . Although the network.service not work ping
192.168.20.10 it ok.

No matter what I run systemctl restart network or not run . this pc cannot
communication with any packetfence ip
ping 192.168.20.10 destination host unreachable
ping 192.168.30.10 timeout
ping 192.168.25.10 timeout
