Drops on the ethernet interfaces

Post by oSAlj » 2021/04/26 12:32:58

Hi,

I have a server with a 4-ports network card.

I set up bonding and bridge.

Everything works as it should.

I only have a small problem because each interface has a lot of drops.

Results below:

Code: Select all

Device	Received	Sent	  Err/Drop
bond0	3.85 GiB	11.76 GiB  0/1400
br0	3.45 GiB	11.28 GiB  0/5277
em1	7.47 MiB	4.54 MiB   0/5137
lo	6.25 MiB 	6.25 MiB   0/0
p3p1	2.92 GiB	7.54 GiB   0/686
p3p2	957.60 MiB	4.23 GiB   0/15
I also attach the interface configuration:

root@host01 network-scripts]# cat ifcfg-p3p1

Code: Select all

DEVICE=p3p1
TYPE=Ethernet
USERCTL=no
ONBOOT=yes
BOOTPROTO=none
NM_CONTROLLED=no
MASTER=bond0
SLAVE=yes
[root@host01 network-scripts]# cat ifcfg-p3p2

Code: Select all

DEVICE=p3p2
TYPE=Ethernet
USERCTL=no
ONBOOT=yes
BOOTPROTO=none
NM_CONTROLLED=no
MASTER=bond0
SLAVE=yes
[root@host01 network-scripts]# cat ifcfg-bond0

Code: Select all

DEVICE=bond0
NAME=bond0
TYPE=Bond
ONBOOT=yes
BRIDGE=br0
BOOTPROTO=none
NM_CONTROLLED=no
BONDING_OPTS="mode=0 miimon=100"
[root@host01 network-scripts]# cat ifcfg-br0

Code: Select all

DEVICE=br0
TYPE=Bridge
BOOTPROTO=none
IPADDR=192.168.1.200
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
DNS1=192.168.1.10
DNS2=192.168.1.245
DNS3=8.8.8.8
ONBOOT=yes
The uptime server is:

Code: Select all

[root@host01 network-scripts]# uptime
 13:31:48 up  5:49,  2 users,  load average: 0.51, 0.55, 0.57
I have no internet problems on this server, but I wonder where the amount of drops is from.
