show interfaces mac-database (Gigabit Ethernet)

Syntax

show interfaces mac-database (ge-fpc/pic/port | ge-fpc/pic/port.n)

<mac-address mac-address>

Release Information

Command introduced before JUNOS Release 7.4.

Description

(M-series and T-series routing platforms only) Display media access control (MAC) address information for the specified Gigabit Ethernet interface. (You can include wildcard characters in the interface name to display more than one Gigabit Ethernet interface. See Interface Types.)

Options

ge-fpc/pic/port—Display MAC addresses that have been learned on all logical interfaces on a particular physical interface.

ge-fpc/pic/port.n—Display MAC addresses that have been learned on a particular logical interface.

mac-address mac-address—(Optional) Display detailed MAC address statistics, including policer information.

Required Privilege Level

Table 29: show interfaces mac-database Output Fields

Field Name	Field Description
Physical Interface
Physical interface	Name of the physical interface.
Enabled	State of the physical interface. Possible values are described in Enabled Field.
Interface index	Physical interface index number, which reflects its initialization sequence.
SNMP ifIndex	SNMP index number for the physical interface.
Description	Description and name of the interface.
Link-level type	Encapsulation being used on the physical interface.
MTU	MTU size on the physical interface.
Speed	Speed at which the interface is running.
Loopback	Whether loopback is enabled and the type of loopback: local or remote.
Source filtering	Whether source filtering is configured.
Flow control	Whether flow control is enabled or disabled.
Device flags	Information about the physical device. Possible values are described in Device Flags.
Interface flags	Information about the interface. Possible values are described in Interface Flags.
Link flags	Information about the link. Possible values are described in Link Flags.
Logical Interface
Logical interface	Name of the logical interface.
Index	Logical interface index number, which reflects its initialization sequence.
SNMP ifIndex	Logical interface SNMP interface index number.
Flags	Information about the logical interface (possible values are described in Logical Interface Flags).
Encapsulation	Encapsulation on the logical interface.
MAC address, Input frames, Input bytes, Output frames, Output bytes	MAC address and corresponding number of input frames, input bytes, output frames, and output bytes.
Number of MAC addresses	Number of MAC addresses configured.
Policer Statistics	(Displayed for mac-address option only) Display information about policers applied to a logical interface-MAC pair. Policer type—Type of policer that is out of spec with respect to the configuration. It can be one or more of the following: Input premium—Number of high-priority rating out-of-spec frames or bytes received. Output premium—Number of high-priority rating out-of-spec frames or bytes sent. Input aggregate—Total number of out-of-spec frames or bytes received. Output aggregate—Total number of out-of-spec frames or bytes sent. Discarded Frames—Number of discarded frames. Discarded Bytes—Number of discarded bytes.
