Show Interface

Shows software interface information including counters and features.

show interface [address|addr|features|feat] [<interface> [<interface> [..]]]


Example of how to show the interface counters:

vpp# show int
              Name               Idx       State          Counter          Count
TenGigabitEthernet86/0/0          1         up       rx packets               6569213
                                                     rx bytes              9928352943
                                                     tx packets                 50384
                                                     tx bytes                 3329279
TenGigabitEthernet86/0/1          2        down
VirtualEthernet0/0/0              3         up       rx packets                 50384
                                                     rx bytes                 3329279
                                                     tx packets               6569213
                                                     tx bytes              9928352943

local0                            0        down

Example of how to display the interface placement:

vpp# show interface rx-placement
Thread 1 (vpp_wk_0):
  node dpdk-input:
    GigabitEthernet7/0/0 queue 0 (polling)
  node vhost-user-input:
    VirtualEthernet0/0/12 queue 0 (polling)
    VirtualEthernet0/0/12 queue 2 (polling)
    VirtualEthernet0/0/13 queue 0 (polling)
    VirtualEthernet0/0/13 queue 2 (polling)
Thread 2 (vpp_wk_1):
  node dpdk-input:
    GigabitEthernet7/0/1 queue 0 (polling)
  node vhost-user-input:
    VirtualEthernet0/0/12 queue 1 (polling)
    VirtualEthernet0/0/12 queue 3 (polling)
    VirtualEthernet0/0/13 queue 1 (polling)
    VirtualEthernet0/0/13 queue 3 (polling)

Clear Interfaces
