  1. врядли это нехватка каких то ресурсов в том числt и TKAM`a, наверняка бы сказалось и на других вланах sh module 5 Mod Ports Card Type Model Serial No. --- ----- -------------------------------------- ------------------ ----------- 5 5 Supervisor Engine 720 10GE (Active) VS-S720-10G SAL1248BAMV Mod MAC addresses Hw Fw Sw Status --- ---------------------------------- ------ ------------ ------------ ------- 5 001e.4af8.8d98 to 001e.4af8.8d9f 2.1 8.5(2) 12.2(33)SXH3 Ok Mod Sub-Module Model Serial Hw Status ---- --------------------------- ------------------ ----------- ------- ------- 5 Policy Feature Card 3 VS-F6K-PFC3C SAL12458W65 1.0 Ok 5 MSFC3 Daughterboard VS-F6K-MSFC3 SAL12448TWS 1.0 Ok Mod Online Diag Status ---- ------------------- 5 Pass ну вобщем такая же история, только вот в этом влане никакого мусора не наблюдается. никакой зивисимости по времени нет, может работать долго и никаких проблем не испытывать. очень похоже на потерю или подмену arp записи, но вот дилемма arp запись висит верная и на правильном порту, хотя помогает именно очистка этой записи. в какую сторону копать ума не приложу.
  2. собственно суть проблемы в следующем: периодически перестают пинговаться ip шники находящиеся во влане. при этом если сделать clear ip arp на непингующийся адрес, то он начинает пинговаться. никакой зависимости по времени не отмечено, проблема возникает эпизодически. sh int vl 4090 Vlan4090 is up, line protocol is up Hardware is EtherSVI, address is 0023.eadf.2400 (bia 0023.eadf.2400) Internet address is 172.21.6.1/24 MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation ARPA, loopback not set Keepalive not supported ARP type: ARPA, ARP Timeout 04:00:00 Last input 00:00:00, output 00:00:00, output hang never Last clearing of "show interface" counters 00:13:51 Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0 Queueing strategy: fifo Output queue: 0/40 (size/max) 5 minute input rate 3000 bits/sec, 4 packets/sec 5 minute output rate 0 bits/sec, 0 packets/sec L2 Switched: ucast: 17 pkt, 1548 bytes - mcast: 244 pkt, 16523 bytes L3 in Switched: ucast: 2451 pkt, 167240 bytes - mcast: 0 pkt, 0 bytes mcast L3 out Switched: ucast: 2504 pkt, 171460 bytes mcast: 0 pkt, 0 bytes 5635 packets input, 515305 bytes, 0 no buffer Received 259 broadcasts (0 IP multicasts) 0 runts, 0 giants, 0 throttles 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored 3788 packets output, 254190 bytes, 0 underruns 0 output errors, 0 interface resets 0 output buffer failures, 0 output buffers swapped out sh ru int vl 4090 Building configuration...
