Setting the encryption function
1. To enable this function, set "2" in the following service mode (Lv.2).
COPIER > TEST > NET-CAP > ENCDATA
• 0: Encrypted when data is extracted (factory default setting).
• 1: Not encrypted when data is extracted.
• 2: When data is extracted, a ciphertext file and a plaintext file are extracted.
The extension of extracted packet data will be "XXX.can" when encryption settings are enabled.
The extension of extracted packet data will be "XXX.cap" when encryption settings are disabled.
This setting only applies when extracting data by the USB flash drive.
NOTE:
When SST is used to collect data, both plaintext data and ciphertext data are extracted, and this setting is ignored.
Setting the payload drop function
1. To enable this setting, set "1" in the following service mode (Lv.2).
COPIER > TEST > NET-CAP > PAYLOAD
• 0: Not drop the payload (factory default settings)
• 1: Drop the payload
The obtained packet data includes a header part and data part. The header part includes data such as the TCP header and
IP header. The data part includes the actual data.
Enabling this function discards the actual payload data and extracts only the data from the header part, which has the following
effects.
• Can be used when customer data is not allowed to be extracted
• Can be used in an environment where traffic is highly overloaded
Setting the filter function
1. To enable this function, set "1" in the following service mode (Lv.2).
COPIER > TEST > NET-CAP > SIMPFILT
• 0: All data is collected without being filtered (factory default setting).
• 1: Data is filtered.
If this function is enabled, only packet data that includes the machine's MAC address in the packet header is captured.
Setting the startup collection function
1. To enable this function, set "1" in the following service mode (Lv.2).
COPIER > TEST > NET-CAP > PONSTART
• 0: Not automatically collect at startup (factory default setting)
• 1: Data is filtered.
If this function is enabled, only packet data that includes the machine's MAC address in the packet header is captured.
■ Saving of Manual Logs, Network Packet Logs and Key Operation Logs
Follow the procedure shown below to save debug logs (manual logs, network packet logs, and key operation logs) that require
manual operation to the save area of the host machine.
