Ух, народ, подскажите, в чем может быть дело?
Есть Cisco. Прямо скажем, не последния, не крутая,
да от нее этого и не требудется

В последнюю неделю начала себя довольно странно вести.
Ethernet0 is up, line protocol is up
  Hardware is Lance, address is 0000.0c3e.938d (bia 0000.0c3e.938d)
  Internet address is 193.201.152.1/30
  MTU 1500 bytes, BW 10000 Kbit, DLY 1000 usec, rely 255/255, load 8/255
  Encapsulation ARPA, loopback not set, keepalive set (10 sec)
  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 03:33:46

Вот откуда, с чего бы взяться этим resets и collisitons?

PS Но колесу бил, стекла протирал. В смысле, циску менял, сетевую на том конце менял,
   витую тоже менял. А?
