Syntax
show interfaces port-channel [channel-number] [brief] [description]
Parameters
channel-number
For a Port Channel interface, enter the keyword port-channel then a number. The range is from 1 to 128.
NOTE: This command also enables you to view information corresponding to a range of ports.
  • For port-channel interfaces, you can specify multiple ports as port-range. For example, if you want to display information corresponding to all ports between 1 and 4, specify the port range as show interfaces port-channel 1 - 4.
brief
(OPTIONAL) Enter the keyword brief to display only the port channel number, the state of the port channel, and the number of interfaces in the port channel.
description
(OPTIONAL) Displays the port-channel information with description.

Usage Information
The following describes the show interfaces port-channel command shown in the following example.
Field
Description
Port-Channel 1...
Displays the LAG’s status. In the Example, the status of the LAG’s LAG fate-sharing group (“Failover-group”) is listed.
Hardware is...
Displays the interface’s hardware information and its assigned MAC address.
Port-channel is part...
Indicates whether the LAG is part of a LAG fate-sharing group (“Failover-group”).
Internet address...
States whether an IP address is assigned to the interface. If an IP address is assigned, that address is displayed.
MTU 1554...
Displays link and IP MTU.
LineSpeed
Displays the interface’s line speed. For a port channel interface, it is the line speed of the interfaces in the port channel.
Members in this...
Displays the interfaces belonging to this port channel.
ARP type:...
Displays the ARP type and the ARP timeout value for the interface.
Last clearing...
Displays the time when the show interfaces counters were cleared.
Queueing strategy.
States the packet queuing strategy. FIFO means first in first out.
packets input...
Displays the number of packets and bytes into the interface.
Input 0 IP packets...
Displays the number of packets with IP headers, VLAN tagged headers, and MPLS headers. The number of packets may not add correctly because a VLAN tagged IP packet counts as both a VLAN packet and an IP packet.
0 64-byte...
Displays the size of packets and the number of those packets entering that interface. This information is displayed over two lines.
Received 0...
Displays the type and number of errors or other specific packets received. This information is displayed over three lines.
Output 0...
Displays the type and number of packets sent out the interface. This information is displayed over three lines.
Rate information...
Displays the traffic rate information into and out of the interface. Traffic rate is displayed in bits and packets per second.
Time since...
Displays the time since the last change in the configuration of this interface.

User Information
The following describes the show interfaces port-channel brief command shown in the following example.
Field
Description
LAG
Lists the port channel number.
Mode
Lists the mode:
  • L3 — for Layer 3
  • L2 — for Layer 2
Status
Displays the status of the port channel.
  • down — if the port channel is disabled (shutdown)
  • up — if the port channel is enabled (no shutdown)
Uptime
Displays the age of the port channel in hours:minutes:seconds.
Ports
Lists the interfaces assigned to this port channel.
(untitled)
Displays the status of the physical interfaces (up or down).
  • In Layer 2 port channels, an * (asterisk) indicates which interface is the primary port of the port channel. The primary port sends out interface PDU.
  • In Layer 3 port channels, the primary port is not indicated.
Example
DellEMC# show interfaces port-channel 1 brief

LAG Mode Status Uptime    Ports
1   L2   up     00:00:08  Te 3/1  (Up) *
                          Te 3/2 (Down)
