> Cisco 3825 showing the following errors - looking for input... (your error log quoted below my signature)
We saw the same think on a cisco 7206-vxr with npe-t1 (1 gig memory) running c7200-jk9su2-mz.124-16, and with lots of memory always available. We found a reference to "arp throttle", which appears to be a method to deal with a flood of packets to a non-existent address in a way that keeps it from turning into a flood of ARP requests on a directly connected net. The error message line starting with "Total free: 0" makes it seem like there is a hard limit of 500 "somethings". It's not clear to me what that is. (Unanswered, not yet timed-out ARP requests?) >From our router: | #sh mem summ | inc arp throttle | 0x6148AA98 0000002092 0000000001 0000002092 CEF: arp throttle chunk | 0x6148AA98 0000016000 0000000001 0000016000 CEF: arp throttle chunk So there doesn't appear to be a lot going on there. We'd guessed that we were seeing periods where there were a high number of incoming probes trying to scan some of our directly attached LANs, but we have not done any further investigation. (Mostly, it hasn't seemed to cause a problem yet, and so...) I'd also be interested if anyone has any further insight. -- Bob Tinkelman <[EMAIL PROTECTED]> ISPnet, Inc. http://www.ispnetinc.net > Aug 31 13:13:36: %SYS-4-CHUNKMALLOCFAIL: Could not allocate chunks for CEF: > arp throt > Total free: 0, Total inuse: 500, Cause : Not a dynamic chunk > -Process= "<interrupt level>", ipl= 1, pid= 87 -Traceback= 0x612B36C4 > 0x6002CA54 0x6002CAB8 0x615F1CD0 0x6005E8D8 0x60057CD0 0x60A15770 0x60A18448 > 0x602CD374 0x60AFD9B8 > Aug 31 13:15:35: %SYS-4-CHUNKMALLOCFAIL: Could not allocate chunks for CEF: > arp throt > Total free: 0, Total inuse: 500, Cause : Not a dynamic chunk > -Process= "<interrupt level>", ipl= 1, pid= 87 -Traceback= 0x612B36C4 > 0x6002CA54 0x6002CAB8 0x615F1CD0 0x6005E8D8 0x60057CD0 0x60A15770 0x60A18448 > 0x602CD374 0x60AFD9B8 > Aug 31 13:19:19: %SYS-4-CHUNKMALLOCFAIL: Could not allocate chunks for CEF: > arp throt > Total free: 0, Total inuse: 500, Cause : Not a dynamic chunk > -Process= "<interrupt level>", ipl= 1, pid= 87 -Traceback= 0x612B36C4 > 0x6002CA54 0x6002CAB8 0x615F1CD0 0x6005E8D8 0x60057CD0 0x60A15770 0x60A18448 > 0x602CD374 0x60AFD9B8 _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
