Q. When should 64-bit counters be used?

A. RFC 2233 leavingcisco.com adopted expanded 64-bit counters for high capacity interfaces in which 32-bit counters do not provide enough capacity and wrap too fast.

As the speed of network media increases, the minimum time in which a 32-bit counter wraps decreases. For example, a 10 Mbps stream of back-to-back, full-size packets causes ifInOctets to wrap in just over 57 minutes. At 100 Mbps, the minimum wrap time is 5.7 minutes, and at 1 Gbps, the minimum is 34 seconds.

Note: The SNMP counters wrap, the command line interface (CLI) counters do not.

For interfaces that operate at 20,000,000 (20 million) bits per second or less, you must use 32-bit byte and packet counters. For interfaces that operate faster than 20 million bits per second, and slower than 650,000,000 bits per second, you must use 32-bit packet counters and 64-bit octet counters. For interfaces that operate at 650,000,000 bits/second or faster, 64-bit packet and octet counters must be used.

Correspondingly, Cisco IOS® Software does not support 64-bit counters for interface speeds of less than 20 Mbps. This means that 64-bit counters are not supported on 10 Mb Ethernet ports, only 100 Mb Fast-Ethernet and other high speed ports support 64-bit counters.

How do I create a screenshot on Mac OS
To create a screenshot on a Mac, use the following commands:
Apple (Command) Key +Shift+3
Captures a picture of the entire desktop, which is saved on the desktop as a file called ‘picture #’. This option lets you capture the whole screen. If you want just one window on your screen, you will have to edit the picture using image editing software (or use one of the other commands, instead).

Apple (Command) Key +Shift+4
Allows you to use your mouse to select a specific part of your desktop for capture. When your mouse pointer turns into an “x”, hold down the mouse button and drag to select the part of the screen you want. When you release the button, the screenshot will capture the selected part of the screen.  Press Esc to release.

Apple (Command) Key +Shift+4 then press Spacebar
Allows you to select which window to capture.
