Selamlar,
Bir kaç gündür çözemediğimiz bir problem var,değerli yorumlarınızı
bekliyorum.
herkese iyi çalışmalar.
Problem router ethernetinde yapılan sun interfacelerin otomatik
olarak farklı bandwidth'ler alması,tek-tips forumlarında bir sonuç
alamadım ama önerileri de sunuyorum.

Hi,
On a 3700 cisco router i got the following configuration on ethernet;
interface FastEthernet0/0
no ip address
no ip route-cache
no ip mroute-cache
duplex auto
speed auto
!
interface FastEthernet0/0.1
encapsulation dot1Q 10
ip address 10.1.222.1 255.255.255.248
ip access-group 105 in
ip accounting access-violations
no ip route-cache
no ip mroute-cache
!
interface FastEthernet0/0.2
encapsulation dot1Q 2
ip address 1.4.52.1 255.255.255.0
no ip route-cache
no ip mroute-cache
Now ,the problem is when i try to see the bandwidths of each
interface i see the following thing that i couldn't understand:
router_3700#sh interface FastEthernet0/0.2
FastEthernet0/0.2 is up, line protocol is up
Hardware is Gt96k FE, address is 000b.bec3.8cd0 (bia 000b.bec3.8cd0)
Internet address is 2.16.128.1/24
MTU 1500 bytes, BW 10000 Kbit, DLY 1000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation 802.1Q Virtual LAN, Vlan ID 2.
ARP type: ARPA, ARP Timeout 04:00:00
router_3700#sh interface FastEthernet0/0.1
FastEthernet0/0.1 is up, line protocol is up
Hardware is Gt96k FE, address is 000b.bec3.8cd0 (bia 000b.bec3.8cd0)
Description: SUBE
Internet address is 2.16.2.1/24
MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation 802.1Q Virtual LAN, Vlan ID 1.
ARP type: ARPA, ARP Timeout 04:00:00
as you see at the second subinterface
BW 10000 Kbit
at the first subinterface
BW 100000 Kbit
why is this difference,both are attached to same port on a 10/100
switch?
thank you friends.

the first thing i noticed is that the speed and duplex are both set
to auto. auto-negotiation works about as well as plug-n-play, which
is to say it works for <bleep>.
it would appear then that one subinterface is auto-negotiating to 100
full, and the other to 10 half.
try hardcoding (on the switch and the router) to all 100 full.

Another tip would be to turn on "ip route-cache". Although it's not
related to your problem, it is definately a scalability problem.

jdel;
i did what you said exactly;
changed the speed manually ;100 the port connected the router,and the
port of the router..but problem remains.
