SOC/6/SOCL2TPHOSTCARLOG: Packets were dropped in HOST-CAR. (Host-CarID=[Host-CarID], L2TP Tunnel ID=[Tunnel-ID], Session ID=[Session-ID], Source IP=[Source-IP], Destination IP=[Destination-IP])

In VS mode, this log is supported only by the admin VS.

Description

Packets to be sent to the CPU on an LNS were dropped by host-CAR.

Parameters

Parameter Name	Parameter Meaning
Host-CarID	Host-CAR ID
Tunnel-ID	L2TP tunnel ID
Session-ID	Session ID
Source-IP	Source IP address
Destination-IP	Destination IP address

Possible Causes

1. The LNS was attacked by a specific type of packet.

2. The host-CAR for the packets to be sent to the CPU was set low, causing valid packets to be dropped.

Procedure

1. Check whether the bandwidth of packets to be sent to the CPU is the same as the default one.

If the bandwidth is different from the default one, go to Step 2.
If the bandwidth is the same as the default one, go to Step 3.

2. Run the undo hostcar command in the slot view to restore the bandwidth of packets to be sent to the CPU to the default one.

3. Collect alarm, log, and configuration information, and contact technical support personnel.
