I can't ping vlan (192.168.1.1) from pc and inverse

this is my network

now PC0 and PC1 taken ip from dhcp server swithch and OK ,

and I have very simple config

this map is realy and I used packe trace for show you.

1-dhcp

sw(config)#ip dhcp pool ronidhcp

sw(dhcp-config)#network 192.168.1.1 255.255.255.0

sw(dhcp-config)#default-router 192.168.1.2

sw(dhcp-config)#dns-server 4.2.2.4

sw(dhcp-config)#exit

sw(config)#

sw(config)#ip dhcp excluded-address 192.168.1.1 192.168.1.100

2-Vlan

sw(config)#vlan 2

sw(config-vlan)# name soft-sw1

sw(config-vlan)#exit

sw(config)#

3-add ip to vlan

sw(config)#interface vlan 2

sw(config-if)#ip address 192.168.1.1 255.255.255.0

sw(config-if)#no shutdown

sw(config-if)#exit

sw(config)#

4-add interface to Vlan

sw(config)#interface range fastEthernet 0/1-2

sw(config-if-range)#switchport mode access

sw(config-if-range)#describtion Localsystem

sw(config-if-range)# switchport access vlan 2

sw(config-if-range)#no shutdown

sw(config-if-range)#exit

sw(config)#Ctrl+z

sw#copy running-config startup-config

Destination filename [startup-config]?

Building configuration...

[OK]

sw#

Try a simple adjustment. Under the DHCP change "sw(dhcp-config)#network 192.168.1.1 255.255.255.0" to "sw(dhcp-config)#network 192.168.1.0 255.255.255.0".

No change? Still can't ping?

Have the PCs relearn their IP addresses. They may still have the correct network setting.

On another note, why is the gateway 192.168.1.2 and not the VLAN interface's 192.168.1.1. Is there another device?

[majid_peidaei]

i think my gareway and vlan should be 192.168.1.1

yes?

[majid_peidaei]

ok

now my gateway and vlan is 192.168.1.1

but i can't ping right now 

[chrihussey]

Are you doing this in packet tracer? If so can you remove the PC hosts altogether and then put them back.

i dont have problem with this design in lab 

i hav problem in real switch and pc

i have Cisco ME 3400-24TS-A Switch and pc

[chrihussey · Accepted solution]

Might be the default VLAN structure of that type of switch:

UNI-ENI isolated VLAN—This is the default VLAN state for all VLANs created on the switch. Local switching does not occur among UNIs or ENIs on the switch that belong to the same UNI-ENI isolated VLAN. This configuration is designed for cases when different customers are connected to UNIs or ENIs on the same switch. However, switching is allowed among UNIs or ENIs on different switches even though they belong to the same UNI-ENI isolated VLAN.

See the link below. May have to make it a community VLAN:

thaks

i with this

ronisw(config)#interface range fastEthernet 0/1-7
ronisw(config-if-range)#port-type nni
ronisw(config-if-range)#
*Mar 1 06:16:17.803: %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan2, cha
nged state to down
*Mar 1 06:16:48.036: %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan2, cha
nged state to up

and then i fix problem and i have ping switch with pc
