Usage Guidelines
You can use the show interface capabilities command only for physical interfaces.
If the interface and transceiver speed is mismatched, the SFP validation failed message is displayed when you enter the show interface ethernet slot /[ QSFP-module /] port command. For example, if you insert a 1-Gigabit SFP transceiver into a port without configuring the speed 1000 command, you will get this error. By default, all ports are 10 Gigabits.
Examples
This example shows how to display the interface capabilities for a specific interface:

Usage Guidelines
If the interface and transceiver speed is mismatched, the SFP validation failed message is displayed when you enter the show interface ethernet slot /[ QSFP-module /] port command. For example, if you insert a 1-Gigabit SFP transceiver into a port without configuring the speed 1000 command, you will get this error.
By default, all ports on a Cisco Nexus 5000 Series switch are 10 Gigabits.

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. |

The show interface transceiver details command output:
- When the small form-factor pluggable (SFP) port is shut down and the laser is turned off, the value of the Current field in the output will be close to zero and the Tx power value will be at a minimum (close to -40 dBm).
- When the SFP port is shutdown and the laser is not turned off, the Current and Tx power values will stay at operational levels. The Rx power value will depend on the behavior of the remote side of the link and the interface status—it can either stay at an operational level, or at a minimum (close to -40 dBm), or N/A.
Note The output for the show interface transceiver command will vary based on the transceiver type, name, part number, revision, and link length of the device.

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).

show vpc brief
To display brief information about the virtual port channels (vPCs), use the show vpc brief command.
show vpc brief [ vpc number ]
Syntax Description
vpc number |
(Optional) Displays the brief information for the specified vPC. The range is from 1 to 4096. |
Command Modes
Any command mode
network-admin
Command History
|
|
5.2(1)N1(1) |
This command was introduced. |
Usage Guidelines
The show vpc brief command displays the vPC domain ID, the peer-link status, the keepalive message status, whether the configuration consistency is successful, and whether the peer-link formed or failed to form.
This command is not available if you have not enabled the vPC feature. See the feature vpc command for information on enabling vPCs.
You can display the track object, if you have configured a tracked object for running vPCs on a single module under the vpc-domain configuration mode.
This command does not require a license.
Examples
This example shows how to display brief information about the vPCs:
switch(config)# show vpc brief
(*) - local vpc is down, forwarding via vPC peer-link
Peer status : peer adjacency formed ok
vPC keep-alive status : peer is alive
Configuration consistency status: success
Number of vPC configured : 1
---------------------------------------------------------------------
id Port Status Active vlans
-- ---- ------ --------------------------------------------------
----------------------------------------------------------------------
id Port Status Consistency Reason Active vlans
-- ---- ------ ----------- -------------------------- ------------
20 Po20 up success success 1-100
This example also shows how to display brief information about the vPCs. In this example, the port channel failed the consistency check, and the device displays the reason for the failure:
switch(config)# show vpc brief
(*) - local vpc is down, forwarding via vPC peer-link
Peer status : peer adjacency formed ok
vPC keep-alive status : peer is alive
Configuration consistency status: failed
Configuration consistency reason: vPC type-1 configuration incompatible - STP interface port type inconsistent
Number of vPC configured : 1
---------------------------------------------------------------------
id Port Status Active vlans
-- ---- ------ --------------------------------------------------
----------------------------------------------------------------------
id Port Status Consistency Reason Active vlans
-- ---- ------ ----------- -------------------------- ------------
20 Po20 up failed vPC type-1 configuration -
This example shows how to display information about the tracked objects in the vPCs:
switch(config)# show vpc brief
(*) - local vpc is down, forwarding via vPC peer-link
Peer status : peer adjacency formed ok
vPC keep-alive status : peer is alive
Configuration consistency status: success
Number of vPC configured : 3
---------------------------------------------------------------------
id Port Status Active vlans
