Monitoring the PPPoE Subinterface

Purpose

Display information about the parameters associated with the PPPoE subinterface.

Action

To display configuration, status, and statistics information of the PPPoE subinterface:

host1:v0#show pppoe subinterface full
show pppoe subinterface fullPPPoE subinterface FastEthernet 2/0.11 is operStatusUp (dynamic)
    PPPoE subinterface FastEthernet 2/0.11 has a session id of 8
    PPPoE subinterface FastEthernet 2/0.11 has source MAC address 0090.1a40.280a
    PPPoE subinterface FastEthernet 2/0.11 has a MTU of 1494
PPPoE Statistics
    In Octets:  165922
    Out Octets: 108283
    In Packets:  3607
    Out Packets: 3608

To display detailed information about the PPPoE subinterface:

host1:v0#show pppoe subinterface fastEthernet 1/1.1.1
PPPoE subinterface fastEthernet 1/1.1.1 is operStatusUp
      URL String: http://www.urlofinterest.com
      MOTM String: a horse walks into a bar
PPPoE subinterface fastEthernet 1/1.1.1 has a session id of 1

        In Octets:  480
        Out Octets: 256
        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

Meaning

Table 42 lists the show pppoe subinterface command output fields.

Table 42: show pppoe subinterface Output Fields

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
