Trunk Configuration Settings
Packet Capture Mode This setting exists for troubleshooting encryption only; packet
capturing may cause high CPU usage or call-processing
interruptions.
Choose one of the following options from the drop-down list box:
None—This option, which serves as the default setting,
indicates that no packet capturing is occurring. After you
complete packet capturing, configure this setting.
Batch Processing Mode—Cisco Unified Communications
Manager writes the decrypted or nonencrypted messages to a
file, and the system encrypts each file. On a daily basis, the
system creates a new file with a new encryption key. Cisco
Unified Communications Manager, which stores the file for
seven days, also stores the keys that encrypt the file in a secure
location. Cisco Unified Communications Manager stores the
file in the PktCap virtual directory. A single file contains the
time stamp, source IP address, source IP port, destination IP
address, packet protocol, message length, and the message. The
IREC tool uses HTTPS, administrator username and password,
and the specified day to request a single encrypted file that
contains the captured packets. Likewise, the tool requests the
key information to decrypt the encrypted file.
Tip You do not have to reset the trunk after enabling/disabling
Packet Capturing.
For more information on capturing packets, refer to the
Troubleshooting Guide for Cisco Unified Communications
Manager.
Packet Capture Duration This setting exists for troubleshooting encryption only; packet
capturing may cause high CPU usage or call-processing
interruptions.
This field specifies the maximum number of minutes that is allotted
for one session of packet capturing. The default setting equals 0,
although the range exists from 0 to 300 minutes.
To initiate packet capturing, enter a value other than 0 in the field.
After packet capturing completes, the value, 0, displays.
For more information on capturing packets, refer to the Cisco
Unified Communications Manager Troubleshooting Guide.
