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

management-vlan

(Optional) Display the Ethernet switching table for a management VLAN.

persistent-mac <interface interface-name>

(Optional) Display the persistent MAC addresses learned for all interfaces or a specified interface. You can use this command to view entries that you want to clear for an interface that you intentionally disabled.

sort-by (name | tag)

(Optional) Display VLANs in ascending order of VLAN IDs or VLAN names.

vlan vlan-name

(Optional) Display the Ethernet switching table for a specific VLAN.

Additional Information

When Layer 2 protocol tunneling is enabled, the tunneling MAC address 01:00:0c:cd:cd:d0 is installed in the MAC table. When the Cisco Discovery Protocol (CDP), Spanning Tree Protocol (STP), or VLAN Trunk Protocol (VTP) is configured for Layer 2 protocol tunneling on an interface, the corresponding protocol MAC address is installed in the MAC table.

Output Fields

For products that support ELS: The table describes the output fields for the show ethernet-switching table command on products that support ELS. Output fields are listed in the approximate order in which they appear.

Table 1: show ethernet-switching table Output fields on Products That Support ELS

Field Name

Field Description

Name of the routing instance.

VLAN name

Name of the VLAN.

MAC address

MAC address or addresses learned on a logical interface.

MAC flags

Status of MAC address learning properties for each interface:

  • S—Static MAC address is configured.

  • D—Dynamic MAC address is configured.

  • L—Locally learned MAC address is configured.

  • SE—MAC accounting is enabled.

  • NM—Non-configured MAC.

Learning VLAN

VLAN ID of the routing instance or VLAN in which the MAC address was learned.

Layer 2 flags

Debugging flags signifying that the MAC address is present in various lists.

Epoch

Spanning-tree-protocolepoch number identifying when the MAC address was learned. Used for debugging.

Sequence number

Sequence number assigned to this MAC address. Used for debugging.

Learning mask

Mask of the Packet Forwarding Engines where this MAC address was learned. Used for debugging.

IPC generation

Creation time of the logical interface when this MAC address was learned. Used for debugging.

For products that do not support ELS: The following table lists the output fields for the show ethernet-switching table command on products that do not support ELS. Output fields are listed in the approximate order in which they appear.

  • 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.

  • persistent—The learned MAC addresses that will persist across restarts of the switch or interface-down events.

All levels except persistent-mac

Type

The type of MAC address. Values are:

  • installed—addresses that are in the Ethernet switching table.

  • uninstalled—addresses that could not be installed in the table or were uninstalled in an interface-down event and will be reinstalled in the table when the interface comes back up.
