Cisco Systems has discovered a problem with revision D of the Cisco 4700-M and Cisco 4700-DC-M where Cisco IOS initializes the router as a 150-MHz processor when in fact it is a 133-MHz processor. This problem causes all timing related functions in the router to be about 13 percent slower. However, this problem does not affect the packet throughput of the router, and in general, routing protocols are tolerant of delays much longer than 13 percent. However time of day functions and the Network Time Protocol are affected.
This problem does not affect any other revision of the Cisco 4700 or the Cisco 4500.
You can tell the revision of the Cisco 4700-M with the Cisco IOS "show version" command:
cisco 4700 (R4K) processor (revision D) with 32768K/16384K bytes of memory.
There are two ways to resolve this problem:
Replace the Cisco 4700-M with a revision E unit.
Use a version of Cisco IOS that has a fix for CSCdi75353.
