[dpdk-users] l2fwd example program error : Cannot init mbuf pool

[dpdk-users] l2fwd example program error : Cannot init mbuf pool

[P D, Arun (Nokia - IN/Bangalore)]

Hello,

I have been trying to run the example program of DPDK namely l2fwd. I have initialized the EAL environments. When I execute the l2fwd program I get error as below.

The error is its failing to initialie mbuf pool.

[root@localhost app]# ./l2fwd -c 2 -n 2

Please let me know if I am missing anything.

Did you allocate just 5*2MB = 10 MB for dpdk? That is hardly enough. I 
did not run l2fwd, but l3fwd example required more than 200 hugepages (> 
500MB). Try to allocate more
