Chapter 51 Configuring the PPPoE Intermediate Agent
Troubleshooting Tips
The event option of the command echoes important messages (interface state change to errdisabled due
to PPPoE discovery packets entering at a rate exceeding the configured limit). it is the only event shown
by the debug pppoe intermediate-agent event command.
The all option enables both package and event options.
The following example illustrates how to enter the debug command with the packet option:
Switch# debug pppoe intermediate-agent packet
PPPOE IA Packet debugging is on
*Sep 2 06:12:56.133: PPPOE_IA: Process new PPPoE packet, Message type: PADI, input
interface: Gi3/7, vlan : 2 MAC da: ffff.ffff.ffff, MAC sa: aabb.cc00.0000
*Sep 2 06:12:56.137: PPPOE_IA: received new PPPOE packet from inputinterface

*Sep 2 06:12:56.137: PPPOE_IA: received new PPPOE packet from inputinterface
(GigabitEthernet3/8)
*Sep 2 06:12:56.137: PPPOE_IA: Process new PPPoE packet, Message type: PADO, input

*Sep 2 06:12:56.137: PPPOE_IA: Process new PPPoE packet, Message type: PADO, input
interface: Gi3/8, vlan : 2 MAC da: aabb.cc00.0000, MAC sa: aabb.cc80.0000
*Sep 2 06:12:56.137: PPPOE_IA: received new PPPOE packet from inputinterface

*Sep 2 06:12:56.145: PPPOE_IA: received new PPPOE packet from inputinterface
(GigabitEthernet3/4)
*Sep 2 06:12:56.145: PPPOE_IA: Process new PPPoE packet, Message type: PADS, input
interface: Gi3/4, vlan : 2 MAC da: aabb.cc00.0000, MAC sa: 001d.e64c.6512
The following example illustrates how to enter the debug command with the event option:
Switch# debug pppoe intermediate-agent event
PPPOE IA Event debugging is on
*Jul 30 19:00:10.254: %PPPOE_IA-4-PPPOE_IA_ERRDISABLE_WARNING: PPPOE IA received 5 PPPOE
packets on interface Gi3/7
*Jul 30 19:00:10.254: %PPPOE_IA-4-PPPOE_IA_RATE_LIMIT_EXCEEDED: The interface Gi3/7 is
receiving more than the threshold set
*Jul 30 19:00:10.394: %PM-4-ERR_DISABLE: STANDBY:pppoe-ia-rate-limit error detected on
Gi3/7, putting Gi3/7 in err-disable stat
Troubleshooting Tips
When the radius-server attribute 31 remote-id global configuration command is entered in the PPPoE
Agent Remote-ID Tag and DSL Line Characteristics feature configuration on the BRAS, the
debug radius privileged EXEC command can be used to generate a report that includes information
about the incoming access interface, where discovery frames are received, and about the session being
established in PPPoE extended NAS-Port format (format d).
