Hi all,
I'm having difficulty about IP address assignment. I have 2 vlan which is VLAN 1 and VLAN 100. My DHCP server is in VLAN 1. I have 2 pc which is reside in VLAN 1 and VLAN 100. My PC in VLAN 1 able to get ip from DHCP server, but my PC in VLAN 100 can't get ip from DHCP server. Below is my current configuration:
CORE Switch configuration:
!
ip routing
!
vlan 100
!
interface Vlan1
ip address 192.168.1.220 255.255.255.0
no ip mroute-cache
no clns route-cache
!
interface Vlan100
description *** int vlan 100 ***
ip address 192.168.100.1 255.255.255.0
ip helper-address 192.168.1.210
no clns route-cache
!
interface FastEthernet1/0/15
description ** to 2900 fa 0/2 trunk ***
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
load-interval 30
!
ACCESS Switch configuration:
!
interface FastEthernet0/2
switchport trunk encapsulation dot1q
switchport mode trunk
!
interface FastEthernet0/17
spanning-tree portfast
!
interface FastEthernet0/18
switchport access vlan 100
spanning-tree portfast
!
interface VLAN1
ip address 192.168.1.158 255.255.255.0
no ip directed-broadcast
no ip route-cache
!
My first PC connected to int fa 0/17 able to get ip from DHCP server, but my second PC connected to int fa 0/18 unable to get ip from DHCP server. Is there any missing configuration that I should add into CORE switch or ACCESS switch ?
Thank in advance.
