Hello, I am using stable_18_01. I have been observing a delay in setting the 10G NIC interface state to UP. It is apparent from VPP CLI itself that using “set interface state TenGigabitEthernet3/0/0 up” taking some time.
And I also see that the SHM client api “sw_interface_set_flags” fails in timeout at the below code snippet. Client code for setting the interface flags.. /* Construct the API message */ M (SW_INTERFACE_SET_FLAGS, mp); mp->sw_if_index = ntohl (msgp->sw_if_index); mp->admin_up_down = msgp->admin_up_down; S (mp); W (ret); And I get “ret” value as “-99” from W(ret) as it times-out for waiting for the response from VPP. /* W: wait for results, with timeout */ #define W(ret) \ do { \ f64 timeout = vat_time_now (vam) + 1.0; \ socket_client_main_t *scm = &vam->socket_client_main; \ ret = -99; \ \ vl_socket_client_read_reply (scm); \ while (vat_time_now (vam) < timeout) { \ if (vam->result_ready == 1) { \ ret = vam->retval; \ break; \ } \ vat_suspend (vam->vlib_main, 1e-5); \ } \ } while(0); This is the dpdk information from dpdk.

Do you have any fix/suggestion? Thanks, Leela sankar
