Unable to use IPFWD application suite

fahadarslan — Tue, 15 Apr 2014 17:48:12 GMT

ipfwd_config first asks for flow id but fails to recognize when provided. Kindly guide how to deal with this?

Thanks

Execution log

-B: -f: (PROGRAM ERROR) Option should have been recognized!?

Try `-B --help' or `-B --usage' for more information.

Using the modified command, route entry can be made without facing above error.

root@p4080ds:/usr/etc# ipfwd_config -P 1904 -B -s 192.168.27.2 -c 1 -d 192.168.28.2 -n 1 -g 192.168.28.2

Route Entry Added successfully

root@p4080ds:~#

where

-c count for source IP address and

-n count for destination IP address

But after following all steps, two machines connected through P4080DS are still not able to ping each other!

Any suggestions?

Hi Arslan

This could be because ipfwd application does not have correct ARP entries for source and destination machines.

Can you capture the packets using tcpdump or wireshark on the port connected to destination machine and see if it is receiving ethernet pkts from P4080 with correct destination mac address?

Sure, let me try capturing the packets.

ipfwd_config is used in USDPAA IPFWD application, please check whether you missed the following steps.

1. Boot up P4080 with usdpaa device tree, and use fmc to configure FMAN policy, for example

cd /usr/etc

fmc -c us_config_serdes_0xe.xml -p us_policy_hash_ipv4_src_dst_32_fq.xml -a.

2. Setup ipfwd_app and make sure it start successfully.

ipfwd_app 1..7 -i fm1-10g,fm2-gb2

3. On the target, use ipfwd_config to add ip and routes configurations.

4. On two machine configure ip, gw, arp for gw and route information.

If your problem remains, please kindly share your Linux console log.

Have a great day,
Yiping Wang
