Hi,
when using config
unix { interactive cli-listen /run/vpp/cli.sock gid 0 } cpu { main-core 1 }
dpdk { dev :05:00.1 } *
* vpp# set int state TenGigabitEthernet5/0/1 up
vpp# set int ip addr TenGigabitEthernet5/0/1 192.168.1.1/24
vpp# ping 192.168.1.254 repeat 6 verbose
Source address: 192.168.1.1
64 bytes from 192.168.1.254: icmp_seq=3 ttl=64 time=.2041 ms *WORK AS EXPECTED
BUT:
* add corelist-workers 2,3 in config
unix { interactive cli-listen /run/vpp/cli.sock gid 0 } cpu { main-core 1
*corelist-workers 2,3* } dpdk { dev :05:00.1 }
