Hi

default router should be the vlan ip address as its the gateway for the subnet

sw(dhcp-config)#default-router 192.168.1.2

change it to below , also each switch should have its default gateway set to in con fog , ip default-gateway x.x.x.x

192.168.1.1

[majid_peidaei]

ok

in this way

vlan ip 192.168.1.1 and gw ip 192.168.1.1

right?

[Mark Malone]

Hi

yes this should be sw(dhcp-config)#default-router 192.168.1.1

this should match the vlan ip address which is already 192.168.1.1

and each switch should also have ...ip default-gateway 192.168.1.1 so traffic can get back to it

[majid_peidaei]

ok

now my gateway and vlan is 192.168.1.1

but i can't ping right now 

[Mark Malone]

ok is the vlan up/up yes on the switch , you can also ping it locally on the switch itself ?

The pc your pinging from is set for vlan 2 and is also up/up , what its ip address

check the arp table on the switch and its mac table make sure you can see your pc mac address and ip address

[majid_peidaei]

this is arp picture

[Mark Malone]

ok cool so it sees one pc correct the .102 address can you ping that you should be able to as its in the table unless something is blocking it software related , are these real pcs or a virtual lab setup ?

[majid_peidaei]

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

[Mark Malone]

ye that's what I needed to know because if you have software firewall on the pc it could be set at high strength blocking your icmp traffic on local pc going in / out

make sure your firewall is turned off while your testing on the pcs and av

is the vlan up/up yes and when your on the actual switch you can ping it ok , the oc is on the arp table so you should be able to ping the vlan unless the interface is down

[majid_peidaei]

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
