DHCP configuration of pool "Lan" looks good.
Hosts should not be having problem getting IP address when attached to ports fa0 - fa3. Fa4 is WAN interface and it is configured as DHCP client.

Eihab Haddad

Thanx Mr.Predrag. but the problem still existing

Predrag Jovic

To speed up ip address assignment to hosts you can issue:
interface range fa0 - 3
spanning-tree portfast
Otherwise host need to wait for 30 seconds until interface is moved to forwarding state.

Can you paste output from commands (with dhcp client host attached):
sh int status
sh ip int brief
sh ip dhcp bind
Configuration of dhcp pool is correct, something else should be issue (please, delete pool bab if it is not needed).

Status of all interfaces assign to VLAN 1 is not connected - all interfaces down like host is not connected at all.
That's the reason why SVI for VLAN 1 is down down.
You can move SVI to up up state with command
interface vlan 1
no autostate
But that still does not resolve host interface is not moved to status connected.

Sorry I posted too much . In Last post vlan status is up but still have the same problem.

Fa1 is connected, vlan status is up.

Predrag Jovic

What is device?
I am asking since speed is a-10 and duplex is a-half (typical for PC in standby).
Some devices are trying to get IP address when they are booting up. Since stp portfast is not issued on ports device may give up before it gets ip address (30 seconds timeout until interface is moved to forwarding state). If it is not PC maybe device requires speed and duplex manual configuration (or disabling of mdix auto).

If nothing else helps, try to reload router

reload
yes

Open in new window

and check after reboot if everything is OK

It's a pc and also I connected my lap top .I reloaded the router formatted it and made new conf .but still the same. After reloading there is a new msg .
(Error opening tftp//255.255.255255/cisconet.cfg (timed out)
And the same msg with end of (router-config)
(Ciscortr.cfg)
And the same error msg with end of (nerwork-config).

I'll do it .I'm a beginner but I'll do what I can to solve the problem.
I'll inform you by the update .
Thanx a lot Mr.Predrag for helping. You're the best

Predrag Jovic

Never format flash on switches and routers if you did not backup all that you need first (or you have no choice).
Also, typically, if you format device that is still operational you want to copy all devices back to flash after formatting (while running configuration is still operational). When rebooted and IOS is not on flash device will enter ROMMON, and commands are different so it can be a little tricky... But, sure... router can be recovered to operational state.

You're welcome.
