Output Fields

Table 1 describes the output fields for the show ethernet-switching interface command. Output fields are listed in the approximate order in which they appear.

Table 1: show ethernet-switching interface Output Fields
Field Name	Field Description
Logical interface	Name of the logical interface.
VLAN members	VLANs associated with this interface.
Tag	VLAN ID.
MAC limit	Number of MAC addresses that can be associated with the interface.
STP state	Spanning Tree protocol (STP) state.
Logical interface flags	Status of Layer 2 learning properties for each interface: `DL`—MAC learning is disabled. `LH`—MAC interface limit has been reached. `AD`—Packets are dropped after the MAC interface limit is reached. `DN`—The MAC interface is down. `MMAS`—The MAC interface is disabled after a MAC address move. `SCTL`—The MAC interface is disabled after a configured storm-control level is exceeded. Note: If the physical interface is shutdown due to storm control, all logical interfaces on the shutdown interface display the SCTL logical interface flag.
Tagging	Tagging state of the VLAN.

Sample Output

show ethernet switching interface (Specific Interface)
show ethernet switching interface (Storm Control in Effect)
show ethernet-switching interface detail
show ethernet-switching interface xe-0/0/2.0 (autostate-exclude enabled on QFX5100 switch)
