Output Fields

For QFX Series, QFabric, NFX Series, EX4600 and OCX1100:

Table 1 lists the output fields for the show ethernet-switching interfaces command on QFX Series, QFabric, NFX Series, EX4600 and OCX1100. Output fields are listed in the approximate order in which they appear.

Table 1: show ethernet-switching interfaces Output Fields
Field Name	Field Description	Level of Output
Interface	Name of a switching interface.	All levels
State	Interface state. Values are up or down.	none, brief, detail, summary
VLAN members	Name of a VLAN.	none, brief, detail, summary
Blocking	Forwarding state of the interface: blocked—Traffic is not being forwarded on the interface. unblocked—Traffic is forwarded on the interface. MAC limit exceeded—The interface is temporarily disabled because of a MAC limiting error. The disabled interface is automatically restored to service when the disable timeout expires. MAC move limit exceeded—The interface is temporarily disabled because of a MAC move limiting error. The disabled interface is automatically restored to service when the disable timeout expires. Storm control in effect —The interface is temporarily disabled because of a storm control error. The disabled interface is automatically restored to service when the disable timeout expires. Storm control shutdown in effect —The interface is temporarily disabled because of a storm control shutdown error. The disabled interface is automatically restored to service when the disable timeout expires.	none, brief, detail, summary
Index	VLAN index internal to Junos OS software.	detail
untagged \| tagged	Specifies whether the interface forwards IEEE802.1Q-tagged or untagged traffic.	detail

Output fields for EX Series:

Table 2 lists the output fields for the show ethernet-switching interfaces command on EX Series switches. Output fields are listed in the approximate order in which they appear.

Table 2: show ethernet-switching interfaces Output Fields
Field Name	Field Description	Level of Output
Interface	Name of a switching interface.	none, brief, detail, summary
Index	VLAN index internal to Junos OS.	detail
State	Interface state. Values are up and down.	none, brief, detail
Port mode	The access mode is the port mode default and works with a single VLAN. Port mode can also be trunk, which accepts tagged packets from multiple VLANs on other switches. The third port mode value is tagged-access, which accepts tagged packets from access devices.	detail
Reflective Relay Status	Reflective relay allows packets to use the same interface for both upstream and downstream traffic. When reflective relay has been configured, the status displayed is always enabled . When reflective relay is not configured, this entry does not appear in the command output.	detail
Ether type for the interface	Ether type is a two-octet field in an Ethernet frame used to indicate which protocol is encapsulated in the payload of an incoming Ethernet packet. Both 802.1Q packets and Q-in-Q packets use this field. The output displayed for this particular field indicates the interface’s Ether type, which is used to match the Ether type of incoming 802.1Q packets and Q-in-Q packets. The indicated Ether type field is also added to the interface’s outgoing 802.1Q and Q-in-Q packets.	detail
VLAN membership	Names of VLANs that belong to this interface.	none, brief, detail,
Tag	Number of the 802.1Q tag.	none, brief, detail,
Tagging	Specifies whether the interface forwards 802.1Q tagged or untagged traffic.	none, brief, detail,
Blocking	The forwarding state of the interface: unblocked—Traffic is forwarded on the interface. blocked—Traffic is not being forwarded on the interface. Disabled by bpdu control—The interface is disabled due to receiving BPDUs on a protected interface. If the `disable-timeout` statement has been included in the BPDU configuration, the interface automatically returns to service after the timer expires. blocked by RTG—The specified redundant trunk group is disabled. blocked by STP—The interface is disabled due to a spanning-tree protocol error. MAC limit exceeded—The interface is temporarily disabled due to a MAC limit error. The disabled interface is automatically restored to service when the disable timeout expires. MAC move limit exceeded—The interface is temporarily disabled due to a MAC move limit error. The disabled interface is automatically restored to service when the disable timeout expires. Storm control in effect—The interface is temporarily disabled due to a storm control error. The disabled interface is automatically restored to service when the disable timeout expires.	none, brief, detail,
Number of MACs learned on IFL	Number of MAC addresses learned by this interface.	detail
mapping	When mapping is configured, the status is one of the following C-VLAN to S-VLAN mapping types: dot1q-tunneled—The interface maps all traffic to the S-VLAN (all-in-one bundling). native—The interface maps untagged and priority tagged packets to the S-VLAN. push—The interface maps packets to a firewall filter to an S-VLAN. policy-mapped—The interface maps packets to a specifically defined S-VLAN. `integer`—The interface maps packets to the specified S-VLAN. When mapping is not configured, this entry does not appear in the command output.	detail
