Configures the CNA link-monitor process to use a 64-bit counter for all polled values.
polling usage use-64-bit-counter [ interval-greater-than <seconds> ] no polling usage use-64-bit-counter
seconds--minute of the hour; range: 5 through 3600
Must be in link configuration mode (config-engine-link), which requires privileged-level access.
Disabled (uses 32 bit counters)
The polling usage use-64-bit-counters command configures the CNA link-monitor process to use 64-bit counters when polling edge routers for link usage data.
By default, the link-monitor process obtains usage data from the router’s smaller, but more reliable, 32-bit counters. However, with a Gigabit Ethernet interface, the 32-bit counter will fill up and roll over to 0 in about 32 seconds.
Your edge router may not update the 64-bit counter as frequently as the 32-bit counter. You should configure a polling interval of 60 seconds if you use the 64-bit counter.
Use the interval-greater-than keyword to prevent the use of 64-bit counters when the collection-rate (see polling usage interval) has been set to a relatively low number which can cause some routers to give incorrect results. For example, if you have set the collection-rate (see polling usage interval) to 60 seconds, and configured interval-greater-than to a value less than 60, then 64-bit counter will NOT be used.
