- Syntax
- show interfaces interface-type[—range]
- Parameters

information:
- For a Loopback
interface, enter the keyword loopback then a number
from 0 to 16383.
- For stack-units,
enter the keywords stack-unit then the slot/port
information.

interface, enter the keyword vlan then a number from
1 to 4094.
- For a tunnel
interface, enter the keyword tunnel then the tunnel
ID. The range is from 1 to 16383.
NOTE This command also enables you to
view information corresponding to a range of ports. However, for
Open Networking (ON) platforms the notation for specifying port range
in the command is different from how you specify in non-ON platforms.
- -range
- (Optional) Enter the range of interfaces for which
you want to view the information. The format is interface-type slot/port/[subport]-slot/port/[subport]

- Usage Information
Use the show interfaces command for details on a specific interface.
NOTE In the CLI output, the power value is rounded to a 3-digit value.
For receive/transmit power that is less than 0.000, an snmp
query returns the corresponding dbm value even though the
CLI displays as 0.000.
NOTE After the counters
are cleared, the line-rate continues to increase until it reaches
the maximum line rate. When the maximum line rate is reached, there
is no change in the line-rate.
- User Information
The following table describes the show interfaces command shown in the 10G example.
- Line
- Description
- TenGigabitEthernet 1/1...
- Interface type and administrative and line protocol
status.
- Hardware is...
- Interface hardware information, assigned MAC address,
and current address.
- Pluggable media present...
- Present pluggable media wavelength, type, and rate.
The error scenarios are:
- Wavelength,
unknown — Unable to determine the optics type
- Unknown
— If the wavelength is reading an error
Dell EMC Networking allows unsupported SFP and
XFP transceivers to be used, but Dell EMC Networking OS might not
be able to retrieve some data about them. In that case, typically
when the output of this field is “Pluggable media present, Media type
is unknown”, the Medium and the XFP/SFP receive power reading data
might not be present in the output.
- Interface index...
- Displays the interface index number the SNMP uses
to identify the interface.
- 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 information.
- LineSpeed
- Displays the interface’s line speed, duplex mode,
and negotiation mode.
- Energy Efficient Ethernet
- Displays whether Energy Efficient Ethernet has been
enabled or not.
- ARP type:...
- Displays the ARP type and the ARP timeout value for
the interface.
- Last clearing...
- Displays the time when the show interfaces counters where cleared.
- Queuing strategy...
- States the packet queuing strategy. FIFO means first
in first out.
- Input Statistics:
- Displays all the input statistics including:
- Number of
packets and bytes into the interface
- Number of
packets with VLAN tagged headers
- Packet size
and the number of those packets inbound to the interface
- Number of
Multicast and Broadcast packets:
- Multicasts
= number of MAC multicast packets
- Broadcasts
= number of MAC broadcast packets
- Number of
runts, giants, and throttles packets:
- runts =
number of packets that are less than 64B
- giants =
packets that are greater than the MTU size
- throttles
= packets containing PAUSE frames
- Number of
CRC, overrun, and discarded packets:
- CRC = packets
with CRC/FCS errors
- overrun =
number of packets discarded due to FIFO overrun conditions
- discarded
= the sum of runts, giants, CRC, and overrun packets discarded without
any processing
- Output Statistics:
- Displays output statistics sent out of the interface
including:
- Number of
packets, bytes, and underruns out of the interface
- Packet size
and the number of the packets outbound to the interface
- Number of
Multicast, Broadcast, and Unicast packets:
- Multicasts
= number of MAC multicast packets
- Broadcasts
= number of MAC broadcast packets
- Unicasts
= number of MAC unicast packets
- Number of
VLANs, throttles, discards, and collisions:
- Vlans =
number of VLAN tagged packets
- throttles
= packets containing PAUSE frames
- discarded
= number of packets discarded without any processing
- collisions
= number of packet collisions
- wred=count
both packets discarded in the MAC and in the hardware-based queues
- Rate information...
- Estimate of the input and output traffic rate over
a designated interval (30 to 299 seconds). Traffic rate is displayed
in bits, packets per second, and percent of line rate.
- Time since...
- Elapsed time since the last interface status change
(hh:mm:ss format).
