Hi,
I met an error as follow:

PMD: eth_em_dev_init(): port_id 1 vendorID=0x8086 deviceID=0x100f
EAL: Error - exiting with code: 1
Cause: Cannot create cluster_mem_pool. Errno: 12 [ENOMEM: 12, ENOSPC: 28, E_RTE_NO_TAILQ: 1003, E_RTE_NO_CONFIG: 1002, E_RTE_SECONDARY: 1001, EINVAL: 22, EEXIST: 17]

I found the solution of issue #2 and added -B. Now, A new error was appeared as follow:

I use dpdk-1.8.0, ubuntu 12.04 in VMware and Intel Corporation 82545EM. Can you help me?

Hello,
I try to capture a constant but significant traffic, around 6Gbps.
dpdk utilities work fine but tcpdump with dpdk support drops likes 5-15% of the pkts because of extra copies and syscalls.

Before I try to update your tool with recent dpdk, how much did you evaluate the performance? Did you have packet drops?

Regards,
PK

Hi,

Packets might be dropped when the speed is fast.

PORT: 0 Rx: 54013914 Drp: 7532022 Tot: 61545936 Perc: 12.238%

TOT: Rx: 54013914 Drp: 7532022 Tot: 61545936 Perc: 12.238%

I tried to use -c 0xf to allocate more cores, it returned error and said "exactly two cores".

How can I set the parameters to capture packets without dropping packets?

Thank you very much.

Hi,
Thank you for your DPDK-Dump app,I want to improve this app's capability.
1、Now I have a intel nic

how can I set up the number of rx/tx queue with the function rte_eth_dev_configure or rte_eth_rx_queue_setup? I tried to change the parameters in your app but it didn't work.
2、My computer have 256 lcores,can I use all of them to achieve the performence limit?
3、Do you know nDPI(deep packet inspection)?How can I combine nDPI with your app?
Could you please to give some advice for me ?
Thank you very much!
