Cisco 2811 Router, DHCP

mbkurt07 · 14.08.2012, 10:26

Merhaba arkadaşlar,
cisco 2811 routerda dhcp ayarlarını yaptım fakat f0/1 e bağladığım pc bir türlü otomatik ip almadı. tanımlanmayan ağ diyor ve ip almıyor.
yardımcı olabilirmisiniz..
yapmış olduğum ayarlar:

Kod:

interface FastEthernet0/1
ip address dhcp
...

ile Interface'in IP Adresini DHCP den almasi gerektigini belirliyorsunuz. Buraya

Kod:

ip addr 192.168.2.1 255.255.255.0

yazin.

merhaba tcos;
dediğiniz gibi yaptım:
interface FastEthernet0/1
ip address 192.168.2.1 255.255.255.0
ip nat inside
ip virtual-reassembly
duplex half
speed auto
bridge-group 1
bridge-group 1 spanning-disabled

fakat hala pc ip alamadı.

packet tarcer da aynı devreyi kurdum ve pc ip aldı.
gerçekte neden almıyor. bilgisi olan var mı?

packet tracerda router ayarlar:

- Router ile PC arasinda Switch varmi? Kablolar dogrumu?
- "show interface fa0/1" ne diyor, status/line protocol up mi?
- Up ise: pc ye sabit bir IP verin ve ping deneyin, cevap aliyormusunuz / MAC Adresini görüyormusunuz Router'in?

router doğrudan f0/1 den pc ye bağlı.

pc ye sabit ip verdiğimde ping atabiliyorum.

show arp yazıncada mac adreslerini görebiliyorum..
gitim_router#show arp

Internet 192.168.2.1 - 001d.46dd.f881 ARPA FastEthernet0/1

fakat dhcp den otomatik ip almıyor..

İlgili arayüzünde Duplex auto yaparmısın ? Ve kira süresini biraz artır . Seninki çok düşük .

Yine olmaz ise pc'den IPconfig / relase ve /renew komutlarını deneyebilirsin.

Router ile pc bağladığın UTP düz kablo olabilir ve düz ise çalışmaz. Çapraz kablo çakmayı biliyorsan kablo uçlarını çapraz olarak çak .

Ayrıca PC ve Router speed/duplex auto yapmalısın.

Kira sürende çok düşük 2 dakıka çok az .

Bize ;
#Show interface fasteth 0/1 komutunun çıktısının sonucunu gönderebilir misin ?

router ile pc arasındaki kablo düz kablo; fakat el ile ip verdiğim zaman çalışıyor.
kira süresinide değiştirdim.

Sıkıntı kaynagı bence kablo ve bu satır " Half-duplex, 100Mb/s, 100BaseTX/FX "

Show ip dhcp server statistic yazarak çıkan sonucta Received kısmında bulunan recieve relase vs . gibi değerlerin 0 oldugunu goruyorsan yapılandırman dogru kablo yanlıs derım .
