Possible depths: 8, 24
Current resolution setting: 1280x1024x76
Current depth: 8
Step 2 To change the color setting to 24 bit, log in as the root user and enter the following commands:
su
Password:
password
/usr/sbin/m64config -depth 24 -res 1152x900x76
Step 3 Reboot the workstation for the new color settings to take effect.
Note The resolution in 24-bit depth is a little lower than is possible with 8-bit depth (1152 x 900 x 76 versus
1280 x 1024 x 76), but the difference is hardly noticeable.
C.3.6 How Do I Collect Thread Dumps?
Thread dumps are helpful references when debugging the Cisco MGM process. To collect thread dumps:

• Group is the group name for which to collect thread dumps. It can be:
– SM
