Centos 6.4, bnx2 in promiscuous mode does not see packets

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Hi,

I hope someone can help me, I cannot seem to get a system's ethernet 
interface to correctly work in promiscuous mode...

I have a Centos 6.4 system with 2 bnx2 interfaces on it.

I have set up eth1 in promiscuous mode and am sending traffic to it 
using the port mirroring configuration on a Nortel 3510-24T switch.
The switch reports that it is sending a fair amount of traffic to the 
mirror port.

However, within Centos 6.4, I only see broadcast traffic from the 
switch:

[root@host eth1]# ifconfig eth1
eth1      Link encap:Ethernet  HWaddr 00:19:B9:E2:30:AE
           UP BROADCAST RUNNING PROMISC MULTICAST  MTU:1500  Metric:1
           RX packets:75 errors:0 dropped:0 overruns:0 frame:0
           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
           collisions:0 txqueuelen:1000
           RX bytes:4800 (4.6 KiB)  TX bytes:0 (0.0 b)

I have tried various options configuring eth1 via 
/etc/sysconfig/networking/devices/ifcfg-eth1

Currently it looks like this:

DEVICE=eth1
BOOTPROTO=static
HWADDR=00:19:B9:E2:30:AE
#NM_CONTROLLED=no
ONBOOT=yes
TYPE=Ethernet
#UUID="e753ec9b-fc35-4460-bcd1-87f26f8d1553"
IPV6INIT=no
USERCTL=no
PROMISC=yes

I have also tried to manually put the interface in promiscuous mode (as 
I think PROMISC=yes is deprecated):

ifconfig eth1 promisc

It shows as being in promiscuous mode via ifconfig...

The relevant parks of bootup / system messages:

Does anyone have any ideas?
