        In Packets:  8
        Out Packets: 8

To display the operational and administrative status of all configured PPPoE subinterfaces:

host1:01#show pppoe subinterface summary
Total PPPoE subinterfaces: 116
Administrative Status:
                    Up: 115
                  Down: 1
Operational Status:
                    Up: 115
                  Down: 1
        LowerLayerDown: 1
            NotPresent: 0

Field Name

Field Description

PPPoE subinterface

Interface specifier

Status

Operational status of the interface. Possible values are:

  • operStatusUp—Interface or subinterface is operational
  • Down—Interface or subinterface is not operational
  • LowerLayerDown—Subinterface is not operational because an underlying interface or subinterface is down

URL String

URL string sent in the PADM message to PPPoE clients

MOTM String

Message of the minute string sent in the PADM message to PPPoE clients

session id

Session ID of the subinterface

source MAC address

MAC address of PPPoE client

MTU

Maximum transfer unit (MTU) value; when derived from the PPPoE MTU tag, the value can only be determined from an active session.

In Octets

Number of octets received on the subinterface

Out Octets

Number of octets transmitted on the subinterface

In Packets

Number of packets received on the subinterface

Out Packets

Number of packets transmitted on the subinterface

Total PPPoE subinterfaces

Number of configured PPPoE subinterfaces

Administrative Status

Administrative status of the PPPoE subinterface. Possible values:

  • Up—Number of subinterfaces not affected by manual administrative intervention
  • Down—Number of subinterfaces that cannot flow because of manual administrative intervention

Operational Status

Operational status of the PPPoE subinterface. Possible values:

  • Up—Number of subinterfaces that are operational
  • Down—Number of subinterfaces that are not operational
  • LowerLayerDown—Number of subinterfaces that are not operational because an underlying interface is down
  • NotPresent—Number of subinterfaces that are not operational because hardware is unavailable
