hi all, I'm running ovs-dpdk(ovs-2.4.9), I found the counter of bond port of br_t is increasing, but I want to know what's these packets, how could I do this?
first, I use `ovs-ofctl snoop br_t`, but it quit quickly as below: > [root@yf-mos-test-net07 ~]# /usr/local/bin/ovs-ofctl snoop > /usr/local/var/run/openvswitch/br_t.mgmt > [root@yf-mos-test-net07 ~]# /usr/local/bin/ovs-ofctl snoop > /usr/local/var/run/openvswitch/br_t.mgmt > ovs-ofctl: /usr/local/var/run/openvswitch/ovs-ofctl.pid: already running > as pid 22082, aborting Then I debug ovs-vswitchd use `gdb -p 213214` and set break as below: > Breakpoint 3, netdev_rxq_recv (rx=0x7f1a5a6ff2c0, buffers=0x7f25e17f9880, > cnt=0x7f25e17f987c) at lib/netdev.c:695 > 695 retval = rx->netdev->netdev_class->rxq_recv(rx, buffers, cnt); > (gdb) finish > Run till exit from #0 netdev_rxq_recv (rx=0x7f1a5a6ff2c0, > buffers=0x7f25e17f9880, cnt=0x7f25e17f987c) > at lib/netdev.c:695 > 0x000000000055eeec in dp_netdev_process_rxq_port (pmd=0x7f25e80d7010, > port=0x1059fd0, rxq=0x7f1a5a6ff2c0) > at lib/dpif-netdev.c:2590 > 2590 error = netdev_rxq_recv(rxq, packets, &cnt); > Value returned is $5 = 11 > (gdb) p packet > No symbol "packet" in current context. > (gdb) p p^CQuit > (gdb) p cnt > $6 = 0 > (gdb) d > Delete all breakpoints? (y or n) y > (gdb) b 2593 if cnt!=0 > Breakpoint 4 at 0x55ef27: file lib/dpif-netdev.c, line 2593. > (gdb) c but cnt is still 0, which means no packets received. At last, I use `ovs-appctl vlog/set dpif_netdev dbg`, but the log show nothing. How could I do this? thank you~
