Use this procedure to verify the NCS 1001 management Ethernet interface state, counters, and configuration before continuing system setup.

Ensure the management interface is up and properly configured before you continue system setup.

You can use interface status commands in Cisco IOS XR EXEC mode to verify the management interface state.

Follow these steps to verify the management interface status:

Procedure

Enter the show interfaces mgmtEth instance command to display the management interface configuration and counters.

Example:


RP/0/RP0/CPU0:ios# show interfaces MgmtEth 0/RP0/CPU0/0
Sun Mar  5 03:21:33.272 CET
MgmtEth0/RP0/CPU0/0 is up, line protocol is up
  Interface state transitions: 1
  Hardware is Management Ethernet, address is 6c9c.ed50.2aa2 (bia 6c9c.ed50.2aa2
)
  Internet address is 10.58.229.131/22
  MTU 1514 bytes, BW 1000000 Kbit (Max: 1000000 Kbit)
     reliability 255/255, txload 0/255, rxload 0/255
  Encapsulation ARPA,
  Full-duplex, 1000Mb/s, CX, link type is autonegotiation
  loopback not set,
  Last link flapped 2d12h
  ARP type ARPA, ARP timeout 04:00:00
  Last input 00:00:00, output 00:00:00
  Last clearing of "show interface" counters never
  5 minute input rate 16000 bits/sec, 22 packets/sec
  5 minute output rate 0 bits/sec, 0 packets/sec
     4959018 packets input, 462164262 bytes, 0 total input drops
     0 drops for unrecognized upper-level protocol
     Received 3531513 broadcast packets, 1419827 multicast packets
              0 runts, 0 giants, 0 throttles, 0 parity
     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
     20720 packets output, 1284846 bytes, 0 total output drops
     Output 0 broadcast packets, 0 multicast packets
     0 output errors, 0 underruns, 0 applique, 0 resets
     0 output buffer failures, 0 output buffers swapped out
     1 carrier transitions

In the above result, the management interface is administratively down.

Verify that the management interface and line protocol are up. You can also use the show interfaces summary and show interfaces brief commands in Cisco IOS XR EXEC mode to verify the management interface status.

Example:


RP/0/RP0/CPU0:ios# show interfaces summary
Sun Mar  5 03:22:45.830 CET
Interface Type          Total    UP       Down     Admin Down
--------------          -----    --       ----     ----------
ALL TYPES               2        2        0        0
--------------
IFT_ETHERNET            1        1        0        0
IFT_NULL                1        1        0        0

Example:

This example shows sample output from the show interfaces brief command. 


RP/0/RP0/CPU0:ios# show interfaces brief
Sun Mar  5 03:23:55.330 CET

               Intf       Intf        LineP              Encap  MTU        BW
               Name       State       State               Type (byte)    (Kbps)
--------------------------------------------------------------------------------

                Nu0          up          up               Null  1500          0
     Mg0/RP0/CPU0/0          up          up               ARPA  1514    1000000

The management interface status output shows the interface state, line protocol, address, MTU, bandwidth, and traffic counters.

What to do next

If the management interface is administratively down, perform these steps:

  • Check the Ethernet cable connection.

  • Verify the IP configuration of the management interface. For details on configuring the management interface, see the Bring-up NCS 1001 chapter.

  • Verify whether the management interface is in the no shut state using the show running-config interface mgmtEth command.

    This example shows sample output from the show running-config interface mgmtEth command. 

    
RP/0/RP0/CPU0:ios#show running-config interface mgmtEth 0/RP0/CPU0/0
Sun Mar  5 03:25:26.191 CET
interface MgmtEth0/RP0/CPU0/0
 ipv4 address 10.58.229.131 255.255.252.0
!

    In the above output, the management interface is in the no shut state.
