Печалит другое:
sh int f0/2
FastEthernet0/2 is up, line protocol is up (connected)
Hardware is Fast Ethernet, address is 8cb6.4fdb.4482 (bia 8cb6.4fdb.4482)

Keepalive set (10 sec)
Full-duplex, 100Mb/s, media type is 10/100BaseTX
input flow-control is off, output flow-control is unsupported

Total output drops и OutDiscards весьма большие значения, никак не могу понять, что нужно сделать для исправления ситуации.
С сайта cisco:
Out-Discard - Description: The number of outbound packets chosen to be discarded even though no errors have been detected. Common Causes: One possible reason to discard such a packet can be to free up buffer space.
Если я правильно понял, происходит переполнение буфера и пакеты убиваются.
Можно ли как-то увеличить размер буфера? К сожалению пока не нашел информации о том как это сделать.
