**Table 1** Description of the **display interface eth-trunk** command output
Item	Description
Eth-Trunk10 current state	Eth-Trunk status: UP: The interface is Up. DOWN: The interface becomes faulty. UP(E-TRUNK-DOWN): The Eth-Trunk goes Down because of E-Trunk negotiation.
Line protocol current state	Link layer protocol status of the Eth-Trunk: DOWN: The link layer protocol of the interface fails or no IP address is assigned to the interface. UP: The link layer protocol of the interface is running properly.
Description	Description of the Eth-Trunk. To specify the parameter, run the description command.
Switch Port	The Eth-Trunk is a Layer 2 interface. Route Port is displayed if the Eth-Trunk is a Layer 3 interface.
Link-type	Link type of the Layer 2 interface. The parameter is displayed only in Layer 2 mode. The options are as follows: access (configured): The interface is manually configured as an access interface. hybrid: The interface is manually configured as a hybrid interface. trunk (configured): The interface is manually configured as a trunk interface. dot1q-tunnel: The interface is manually configured as a Dot1q-tunnel interface. access(negotiated): The interface is used as an access interface through negotiation. trunk(negotiated): The interface is used as a trunk interface through negotiation. To configure the link type of an interface, run the port link-type command.
PVID	Default VLAN ID of the Eth-Trunk.
Hash arithmetic	Hash algorithm used for load balancing among Eth-Trunk member interfaces. The hash algorithm depends on the load balancing mode configured by using the load-balance command. The S2720-EI, S5720I-SI, S5720-LI, S5720S-LI, S5720S-SI, S5720-SI, S5730S-EI, S5730-SI, S6720-LI, S6720S-LI, S6720S-SI, and S6720-SI use the src-dst-ip, source TCP or UDP port number, and destination TCP or UDP port number in the hash algorithm for load balancing regardless of whether you configure this parameter.
Maximal BW	Maximum bandwidth.
Current BW	Current bandwidth.
The Maximum Frame Length	Maximum frame length allowed by the Eth-Trunk. To specify the parameter, run the jumboframe enable command.
IP Sending Frames' Format	Format of frames sent through the IP protocol, which can be PKTFMT_ETHNT_2, Ethernet_802.3, or Ethernet_SNAP.
Hardware address	Device MAC address.
Current system time	Current system time. If the time zone is configured and the daylight saving time is used, the time is in the format of YYYY/MM/DD HH:MM:SS±HH:MM.

Pause	Pause frame.
Total Error	Number of error packets discovered by the Eth-Trunk during physical layer detection.
CRC	Number of CRC error packets received by the Eth-Trunk.
Giants	Number of jumbo frames with the correct FCS received by the Eth-Trunk.
Jabbers	Number of jumbo frames with incorrect FCS received by the Eth-Trunk.
Fragments	Number of fragments received by the Eth-Trunk.
Runts	Number of undersized frames with the correct FCS received by the Eth-Trunk.
DropEvents	Number of received packets that are discarded due to GBP full or back pressure.
Alignments	Number of received frames with alignment errors.
Symbols	Number of received frames with coding errors.
Ignoreds	Number of received MAC control frames in which the OpCode is not PAUSE.
Frames	Number of packets with the incorrect 802.3 length.
Collisions	Number of sent packets. During packet transmission, 1 to 15 conflict events were generated.
ExcessiveCollisions	Number of packets that fail to be sent. During packet transmission, 16 conflict events were generated.
Late Collisions	Number of delayed packets sent by the Eth-Trunk. During packet transmission, conflict events were generated.
Deferreds	Number of delayed packets sent by the Eth-Trunk. During packet transmission, no conflict event was generated.
Buffers Purged	Number of packets aged in the cache because packets sent by the Eth-Trunk have been stored in the queue buffer for a long time.
Input bandwidth utilization	Inbound bandwidth usage.
Output bandwidth utilization	Outbound bandwidth usage.
PortName	Name of the Eth-Trunk member interface.
Status	Status of the Eth-Trunk member interface. Manual mode: Up: indicates that the interface is properly started. Down: indicates that the interface becomes faulty. LACP mode: Up: indicates that the interface is selected. Down: indicates that the interface is not selected.
Weight	Weight of a member interface for load balancing.
The Number of Ports in Trunk	Number of Eth-Trunk member interfaces.
