vovan-pmr Posted March 30, 2011 Posted March 30, 2011 сегодня ночью заметил следующее. на нескольких коммутаторах 4507 по цепочке вдруг выросла загрузка ЦПУ до 100%. продолжалось это минут 20, потом так же неожиданно стихло. Никаких штормов и смен топологии не было. вот что заметил: sh proc cpu so CPU utilization for five seconds: 99%/0%; one minute: 98%; five minutes: 92% PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process 52 12861348481006843823 1277 88.63% 88.12% 82.09% 0 Cat4k Mgmt LoPri далее: sh platform cpu packet statistics Packets Dropped In Hardware By CPU Subport (txQueueNotAvail) CPU Subport TxQueue 0 TxQueue 1 TxQueue 2 TxQueue 3 ------------ --------------- --------------- --------------- --------------- 0 441350 0 0 6600139 2 0 270458662 0 0 RkiosSysPacketMan: Packet allocation failures: 0 Packet Buffer(Software Common) allocation failures: 0 Packet Buffer(Software ESMP) allocation failures: 0 Packet Buffer(Software EOBC) allocation failures: 0 Packet Buffer(Software SupToSup) allocation failures: 0 IOS Packet Buffer Wrapper allocation failures: 0 Packets Dropped In Processing Overall Total 5 sec avg 1 min avg 5 min avg 1 hour avg -------------------- --------- --------- --------- ---------- 321546 0 0 0 0 Packets Dropped In Processing by CPU event Event Total 5 sec avg 1 min avg 5 min avg 1 hour avg ----------------- -------------------- --------- --------- --------- ---------- Input Acl 265860 0 0 0 0 SA Miss 55659 0 0 0 0 L2 Forward 6 0 0 0 0 Packets Dropped In Processing by Priority Priority Total 5 sec avg 1 min avg 5 min avg 1 hour avg ----------------- -------------------- --------- --------- --------- ---------- Normal 197236 0 0 0 0 Medium 55680 0 0 0 0 High 68651 0 0 0 0 Packets Dropped In Processing by Reason Reason Total 5 sec avg 1 min avg 5 min avg 1 hour avg ------------------ -------------------- --------- --------- --------- ---------- SrcAddrTableFilt 24367 0 0 0 0 STPDrop 32638 0 0 0 0 L2DstDrop 348 0 0 0 0 AclActionDrop 196109 0 0 0 0 NoDstPorts 67516 0 0 0 0 NoFloodPorts 568 0 0 0 0 Total packet queues 16 Packets Received by Packet Queue Queue Total 5 sec avg 1 min avg 5 min avg 1 hour avg ---------------------- --------------- --------- --------- --------- ---------- Esmp 1405457257 46 41 34 28 L2/L3Control 793050279 18 14 15 16 Host Learning 201344164 1 49 197 98 L2 Fwd High 5418189 1 0 0 0 L2 Fwd Low 7503987 0 0 0 0 L3 Rx High 293 0 0 0 0 L3 Rx Low 101016721 11 1 0 1 ACL sw processing 581 0 0 0 0 Packets Dropped by Packet Queue Queue Total 5 sec avg 1 min avg 5 min avg 1 hour avg ---------------------- --------------- --------- --------- --------- ---------- L2/L3Control 28541 0 0 0 0 Host Learning 92145754 0 0 0 0 ACL sw processing 58 0 0 0 0 и: sh platform health %CPU %CPU RunTimeMax Priority Average %CPU Total Target Actual Target Actual Fg Bg 5Sec Min Hour CPU K2L2 Address Table R 2.00 92.28 12 9 100 500 108 123 24 13335:19 то есть никаких аномальных загрузок пакетами ЦПУ тоже не было. Единственное это K2L2 Address Table R, но в гугле ничего толкового по этому поводу не нашел. Может у кого была похожая ситуация, не могу выяснить причину...... Вставить ник Quote
