show ethernet-switching table

Syntax



show ethernet-switching table
<brief | detail | extensive>
<interface interface-name>
<vlan (vlan-id | vlan-name)>

Release Information

Command introduced in JUNOS Release 9.0 for EX-series switches.

Description

Displays the Ethernet switching table. If a VLAN range has been configured for any of the VLANs on the switch, the output displays the MAC addresses for the entire series of VLANs.

Options

none — (Optional) Display brief information about the Ethernet switching table for all VLANs on the switch.

brief | detail | extensive — (Optional) Display the specified level of output.

interface-name — (Optional) Display the Ethernet switching table for a specific interface.

vlan (vlan-id | vlan-name) — (Optional) Display the Ethernet switching table for the specified VLAN ID or VLAN name. If a VLAN range has been configured for this VLAN name, the output displays the MAC addresses for the entire series of VLANs that were created for that name.

Table 1: show ethernet-switching table Output Fields

Field Name	Field Description	Level of Output
VLAN	The name of a VLAN.	All levels
MAC address	The MAC address associated with the VLAN. If the If a VLAN range has been configured for a VLAN, the output displays the MAC addresses for the entire series of VLANs that were created with that name.	All levels
Type	The type of MAC address. Values are: static—The MAC address is manually created. learn—The MAC address is learned dynamically from a packet's source MAC address. flood—The MAC address is unknown and flooded to all members.	All levels
Age	The time remaining before the entry ages out and is removed from the Ethernet switching table.	All levels
Interfaces	Interface associated with learned MAC addresses or All-members (flood entry).	All levels
Learned	For learned entries, the time which the entry was added to the Ethernet-switching table.	detail, extensive
