"Cisco 877 PPPoE через Ethernet низкая скорость." Отправлено se000, 15-Авг-10 05:59
Есть циска дома. На ней настроен NAT, интернет подается через Ethernet+PPPoE если провод напрямую в комп втыкаешь и PPPoE на компе то скорость получается Down 97Мегабит \Up 70Мегабит. по данным speedtest.net Если через циску то получается Down 30/ up 22мегабита. больше никак не получается. если ставлю MTU 1492  ip tcp adjust-mss 1452 то скорость еще ниже. иногда начинает сбрасывать соединения , конкретно в браузере появляется connection was reset. помогите настроить или устранить причину такой низкой скорости. Пробова Speed и Duplex во всех вариантах на скорость не влияет существенно. провода тоже исключил. sh ver Cisco IOS Software, C870 Software (C870-ADVIPSERVICESK9-M), Version 12.4(6)T11, RELEASE SOFTWARE (fc2) ROM: System Bootstrap, Version 12.3(8r)YI4, RELEASE SOFTWARE uptime is 5 hours, 45 minutes System returned to ROM by reload System image file is "flash:c870-advipservicesk9-mz.124-6.T11.bin" Last reload reason: Reload Command Cisco 877 (MPC8272) processor (revision 0x200) with 118784K/12288K bytes of memory.
