Line Description
TenGigabitEthernet 0/0... Interface type, slot/port 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, Non-qualified — Dell Force10 ID is not present, but
wavelength information is available from XFP or SFP serial data
• Wavelength, F10 unknown—Dell Force10 ID is present, but not able to
determine the optics type
• Unknown, Non-qualified— if wavelength is reading error, and Dell
Force10 ID is not present
Dell Force10 allows unsupported SFP and XFP transceivers to be used, but
FTOS 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 used by SNMP to identify the interface.
Internet address... States whether an IP address is assigned to the interface. If one is, that address
is displayed.
MTU 1554... Displays link and IP MTU information.
LineSpeed Displays the interface’s line speed, duplex mode, and Slave
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
