Traffic moves to another eth
hi guys
I have a server which has 2 nics eth0 and eth1
eth0 is used for our email traffic server. everything working fine
some time later a eth1 was added for backup purposes so this new nic sends data to another vlan for backup purposes
all of a sudden our mail server starts to fail and we found that protocols or traffic specifically 80 and 8080 is trying to traffic flow using eth1 which is only for backups as I said....
so any idea to link this traffic 80 - 8080 to only eth0?

thanks a lot

Match-all classifier in tc(8) Linux Match-all classifier in tc(8)
NAME
matchall - traffic control filter that matches every packet
SYNOPSIS
tc filter ... matchall [ skip_sw | skip_hw ] [ action ACTION_SPEC ] [ classid CLASSID ]
DESCRIPTION
The matchall filter allows to classify every packet that flows on the port and run a action on it.
OPTIONS
action ACTION_SPEC
Apply an action from the generic actions framework on matching packets.
classid CLASSID
Push matching packets into the class identified by CLASSID.
skip_sw
Do not process filter by software. If hardware has no offload support for this filter, or TC offload is not enabled for the inter-
face, operation will fail.
skip_hw
Do not process filter by hardware.
EXAMPLES
To create ingress mirroring from port eth1 to port eth2:
tc qdisc add dev eth1 handle ffff: ingress
tc filter add dev eth1 parent ffff:
matchall skip_sw
action mirred egress mirror
dev eth2
The first command creats an ingress qdisc with handle ffff: on device eth1 where the second command attaches a matchall filters on it that
mirrors the packets to device eth2.
To create egress mirroring from port eth1 to port eth2:
tc qdisc add dev eth1 handle 1: root prio
tc filter add dev eth1 parent 1:
matchall skip_sw
action mirred egress mirror
dev eth2
The first command creats an egress qdisc with handle 1: that replaces the root qdisc on device eth1 where the second command attaches a
matchall filters on it that mirrors the packets to device eth2.
To sample one of every 100 packets flowing into interface eth0 to psample group 12:
tc qdisc add dev eth0 handle ffff: ingress
tc filter add dev eth0 parent ffff: matchall
action sample rate 100 group 12
