Cisco stores them as 32 bits, but SNMP also retrieves them as 32 bits. HP has a proprietary MIB & impl. for its Lanprobes & RMON s/w for HP workstations, which is 64 bits wide. These are the only devices I know of that store more than 32 bits, and have accurate counts of bytes over a long period of time. So on ciscos, you should clear counters before they can roll over. You should really have a raffle to guess the uptime on your router. ;-) --Dean At 10:46 AM 1/25/1999 -0500, alex@nac.net wrote:
I am working on some byte counting stuff, and have a odd question.
I noticed on my of my routers:
2403558863 packets input, 2476827328 bytes
thats:
2,403,558,863 packets input, 2,476,827,328 bytes
which when divided out, comes to 1.03 bytes per packet, which without saying is obviously in error.
So, when does a Cisco counter 'flip' ? How many bits is it?
