Note the following in the above display:

  • Ethernet 1/5 is a Layer 3-ready interface. The following fields in the display help identify an interface as a configured Layer 3 interface:
    • Mode—routed
    • Status—up
    • Reason—none
  • Ethernet 1/5.2 is a Layer 3 subinterface; however, the interface is not ready for Layer 3 configuration (Status—down).
  • Interface Lo10 is a Layer 3 loopback interface.

This example shows how to display a brief summary of interfaces configured as FabricPath interfaces on a switch that runs Cisco NX-OS Release 5.1(3)N1(1):

The following table describes the significant fields shown in the display.

Table 2. show interface loopback Field Description

Field

Description

Loopback is ...

Indicates whether the interface hardware is currently active (whether carrier detect is present), is currently inactive (down), or has been taken down by an administrator (administratively down).

Hardware

Hardware is Loopback.

MTU

Maximum transmission unit (MTU) of the interface.

BW

Bandwidth (BW) of the interface in kilobits per second.

DLY

Delay (DLY) of the interface in microseconds.

reliability

Reliability of the interface as a fraction of 255 (255/255 is 100 percent reliability), calculated as an exponential average over 5 minutes.

txload

Load on the interface for transmitting packets as a fraction of 255 (255/255 is completely saturated), calculated as an exponential average over 5 minutes.

rxload

Load on the interface for receiving packets as a fraction of 255 (255/255 is completely saturated), calculated as an exponential average over 5 minutes.

Encapsulation

Encapsulation method assigned to interface.

LOOPBACK

Indicates whether loopback is set.

packets input

Total number of error-free packets received by the system.

bytes

Total number of bytes, including data and MAC encapsulation, in the error-free packets received by the system.

multicast frames

Total number of multicast frames enabled on the interface.

compressed

Total number of multicast frames compressed on the interface.

input errors

Sum of all errors that prevented the receipt of datagrams on the interface being examined. This may not balance with the sum of the enumerated output errors, because some datagrams may have more than one error and others may have errors that do not fall into any of the specifically tabulated categories.

frame

Number of packets received incorrectly having a CRC error and a noninteger number of octets. On a serial line, this is usually the result of noise or other transmission problems.

overrun

Number of times the serial receiver hardware was unable to hand received data to a hardware buffer because the input rate exceeded the receiver’s ability to handle the data.

fifo

Number of First In, First Out (FIFO) errors in the receive direction.

packets output

Total number of messages transmitted by the system.

bytes

Total number of bytes, including data and MAC encapsulation, transmitted by the system.

underruns

Number of times that the far-end transmitter has been running faster than the near-end router’s receiver can handle. This may never happen (be reported) on some interfaces.

output errors

Sum of all errors that prevented the final transmission of datagrams out of the interface being examined. Note that this may not balance with the sum of the enumerated output errors, as some datagrams may have more than one error, and others may have errors that do not fall into any of the specifically tabulated categories.

collisions

Loopback interface does not have collisions.

fifo

Number of First In, First Out (FIFO) errors in the transmit direction.

show mac address-table

To display the information about the MAC address table, use the show mac address-table command.

show mac address-table [ address mac-address ] [ dynamic | multicast | static ] [ interface { ethernet slot / [ QSFP-module / ] port | port-channel number } ] [ vlan vlan-id ]

Modification

4.0(0)N1(1a)

This command was introduced.

4.2(1)N1(1)

The vlan keyword was added.

Usage Guidelines

You must use the vlan keyword to determine the use of hardware hashing.

When you do not use hardware hashing, the output displays all parameters used to determine the outgoing port ID. Missing parameters are shown as zero values in the output.

If you do not use hardware hashing, the outgoing port ID is determined by using control-plane selection. Hardware hashing is not used in the following scenarios:

  • The specified VLAN contains an unknown unicast destination MAC address.
  • The specified VLAN contains a known or an unknown multicast destination MAC or destination IP address.
  • The specified VLAN contains a broadcast MAC address.
  • The EtherChannel has only one active member.
  • The destination MAC address is unknown when the load distribution is configured on the source IP address (src-ip), source port (l4-src-port), or source MAC address (src-mac).
  • If multichassis EtherChannel trunk (MCT) is enabled and the traffic flows from a virtual port channel (vPC) peer link, the output displays “Outgoing port id (vPC peer-link traffic)”.

To get accurate results, you must do the following:

  • (For unicast frames) Provide the destination MAC address (dst-mac) and the VLAN for hardware hashing (vlan). When the destination MAC address is not provided, hardware hashing is assumed.
  • (For multicast frames) For IP multicast, provide either the destination IP address (dst-ip) or destination MAC address (dst-mac) with the VLAN for hardware hashing (vlan). For non-ip multicast, provide the destination MAC address with the VLAN for hardware hashing.
  • (For broadcast frames) Provide the destination MAC address (dst-mac) and the VLAN for hardware hashing (vlan).
