Table 1 describes the significant fields shown in the display.
Table 1 show interface loopback 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. |

This command was introduced. |

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).

Usage Guidelines
The STP port type displays only when you have configured the port as either an STP edge port or an STP network port. If you have not configured the STP port type, no port type displays.
If you specify an interface that is not running STP, the switch returns an error message.
When you are running Multiple Spanning Tree (MST), this command displays the Per VLAN Spanning Tree (PVST) simulation setting.
Note If you are running Multiple Spanning Tree (MST), use the show spanning-tree mst command to show more detail on the specified interfaces.
Examples
This example shows how to display STP information on a specified interface:
switch(config)# show spanning-tree interface ethernet 1/3
This example shows how to display detailed STP information on a specified interface:
switch(config)# show spanning-tree interface ethernet 1/3 detail

|
4.0(0)N1(1a) |
This command was introduced. |
Usage Guidelines
This command displays information for all VLANs, including private VLANs, on the switch.
Each access port can belong to only one VLAN. Trunk ports can be on multiple VLANs.
Note Although a port can be associated with a VLAN as an access VLAN, a native VLAN, or one of the trunk allowed ports, only access VLANS are shown under Ports in the display.
If you shut down a VLAN using the state suspend or the state active command, these values appear in the Status field:
- suspended—VLAN is suspended.
- active—VLAN is active.
If you shut down a VLAN using the shutdown command, these values appear in the Status field:
- act/lshut—VLAN status is active but shut down locally.
- sus/lshut—VLAN status is suspended but shut down locally.
If a VLAN is shut down internally, these values appear in the Status field:
- act/ishut—VLAN status is active but shut down internally.
- sus/ishut—VLAN status is suspended but shut down internally.
If a VLAN is shut down locally and internally, the value that is displayed in the Status field is act/ishut or sus/ishut. If a VLAN is shut down locally only, the value that is displayed in the Status field is act/lshut or sus/lshut.
Examples
