Are you sure by default it is not configured any rate? It seems it default to two per second.

Perhaps someone else can provide that informaton. You can rate-limit ICMP generation due to MTU failures: Router(config)#mls rate-limit all mtu-failure ? <10-1000000> packets per second but, by default it not configured to any rate: Router#show mls rate-limit Sharing Codes: S - static, D - dynamic Codes dynamic sharing: H - owner (head) of the group, g - guest of the group Rate Limiter Type Status Packets/s Burst Sharing --------------------- ---------- --------- ----- ------- [...] MTU FAILURE Off - - - so, it's possible that high rate of MTU failures will overload your 65xx/76xx.. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
