"странности с приоритетом"
Отправлено Арсений_В , 28-Фев-06 09:40 
Есть две циски 3725 и 2621 ХМ

Cisco IOS Software, 3700 Software (C3725-ADVIPSERVICESK9-M), Version 12.4(1a), RELEASE SOFTWARE (fc2)
ROM: System Bootstrap, Version 12.2(8r)T2, RELEASE SOFTWARE (fc1)
System image file is "flash:c3725-advipservicesk9-mz.124-1a.bin"
Cisco 3725 (R7000) processor (revision 0.1) with 242688K/19456K bytes of memory.
Processor board ID JMX0808L498
R7000 CPU at 240MHz, Implementation 39, Rev 3.3, 256KB L2 Cache
DRAM configuration is 64 bits wide with parity disabled.
55K bytes of NVRAM.
63488K bytes of ATA System CompactFlash (Read/Write)

Cisco IOS Software, C2600 Software (C2600-ADVIPSERVICESK9-M), Version 12.4(1), RELEASE SOFTWARE (fc3)
ROM: System Bootstrap, Version 12.2(8r) [cmong 8r], RELEASE SOFTWARE (fc1)
System image file is "flash:c2600-advipservicesk9-mz.124-1.bin"
Cisco 2621XM (MPC860P) processor (revision 0x301) with 123444K/7628K bytes of memory.
Processor board ID JAE0823KWZ1 (4160571449)
M860 processor: part number 5, mask 2
32K bytes of NVRAM.
32768K bytes of processor board System flash (Read/Write)

между ними есть выделенный канал 64К,который используется под передачу данных и под телефонию,приоритет голоса перед данными отрабатывает нормально только в том случае, когда закачка (например по фтп) идет в одну сессию (т.е. с одного сайта качаем в одну сессию), если сессий больше чем одна, начинаются ики и так до полной потери голоса

конфиг следующий:
