Cấu hình bandwidth trên R1 và R2 sao cho đúng với rốc độ vật lý:

R1(config)# interface serial 0/0/0

R1(config-if)# bandwidth 800

Step 2: Cấu hình EIGRP

R1(config)# router eigrp 1

R1(config-router)# no auto-summary

R1(config-router)# network 172.16.0.0

Step 3: Kiểm tra hàng đợi trên các interface:

R1# show interfaces serial 0/0/0

Serial0/0/0 is up, line protocol is up

Hardware is GT96K Serial

Internet address is 172.16.12.1/24

MTU 1500 bytes, BW 800 Kbit, DLY 20000 usec,

reliability 255/255, txload 253/255, rxload 1/255

Encapsulation HDLC, loopback not set

Keepalive set (10 sec)

Trang 3

ARP type: ARPA, ARP Timeout 04:00:00

Last input 00:00:32, output 00:00:06, output hang never

Last clearing of "show interface" counters never

Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0

Queueing strategy: fifo

Output queue: 0/40 (size/max)

Steo 4: Kiểm tra và thay đổi loại hàng đợi:

R1# ping 172.16.12.2 repeat 100

Type escape sequence to abort

Sending 100, 100-byte ICMP Echos to 172.16.12.2, timeout is 2 seconds:

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Success rate is 100 percent (100/100), round-trip min/avg/max = 4/19/84 ms

Last clearing of "show interface" counters 00:07:53

Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 2059241

Queueing strategy: weighted fair

Đổi kiểu hàng đợi thành FIFO:

R1(config-if)# no fair-queue

Trang 5

R1(config-if)# hold-queue 1000 out

Step 5: Chỉnh sửa lại cấu hình mặc định của hàng đợi

R1(config-if)# fair-queue 256 32
