Line Description
• Wavelength, Non-qualied — Dell ID is not present, but wavelength information is
available from XFP or SFP serial data
• Wavelength, F10 unknown — Dell ID is present, but not able to determine the optics
type
• Unknown, Non-qualied — if wavelength is reading error, and F10 ID is not present
Dell Networking allows unsupported SFP and XFP transceivers to be used, but Dell
Networking OS might not be able to retrieve some data about them. In that case, typically
when the output of this eld 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 Ecient
Ethernet
Displays whether Energy Ecient 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 rst in rst 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
• Number of FEC bit errors and uncorrected code words:
• FEC bit errors = Number of Forward Error Correction Bit errors occurred.
• FEC uncorrected code words = Number of uncorrected Forward Error Correction
packets.
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
