PacketFence Server : 
eth0 ===> 172.16.205.90/24 
eth0.2 ===> 192.168.2.1/24 
eth0.3 ===> 192.168.3.1/24 

Switch (Cisco 2960): 
Interface Vlan 1===> 172.16.205.91/24 
Interface Vlan 2 ===>192.168.2.2/24 
Interface Vlan 3===> 192.168.3.2/24 
All Vlan interface can communicate with the server same interface. The server 
can't communicate with the vlan 2 and 3. 
When I configure a port and put it in the vlan 2 or 3 I don't receive any DHCP 
configuration. 
That's my switch conf : 
interface FastEthernet0/1 
switchport mode trunk 
! 





interface Vlan1 
ip address 172.16.205.91 255.255.255.0 
no ip route-cache 
! 
interface Vlan2 
ip address 192.168.2.2 255.255.255.0 
no ip route-cache 
! 
interface Vlan3 
ip address 192.168.3.2 255.255.255.0 
no ip route-cache 


My network configuration on the server : 


auto eth3 
iface eth3 inet static 
address 172.16.205.90 
netmask 255.255.255.0 
gateway 172.16.205.254 

auto eth3.2 
iface eth3.2 inet static 
address 192.168.2.1 
netmask 255.255.255.0 
vlan_raw_device eth3 
auto eth3.3 
iface eth3.3 inet static 
address 192.168.3.1 
netmask 255.255.255.0 
vlan_raw_device eth3

Can you specify the IPs/subnets used? 
Maybe all the IPs are on the same subnet and the routing on PF server goes 
through the wrong interface?

Hi, 
I have some issues with the application and I would like to have your opinion 
and whether you have already encountered this problem . 
I ride a test infrastructure . 

Here is my architecture : 
A server running Ubuntu with a physical interface eth0 and two virtual 
sub-interfaces eth0.2, eth0.3 . 

What is happening ? 
PF Serveur can ping the IP ( interface Vlan 1) switch that are in the same LAN. 

The switch has two VLANs (Registration and Isolation ) each have an IP 
interface. Each VLAN interface can ping the virtual sub-interface on the PF 
server IP address. But the PF server is unable to ping the VLAN interfaces on 
the switch and I get this error message ( destination unreachable ) . 

The switch has been configured PF trunk has been established on the port. 
The switch used is a cisco 2960 . 

Have you any idea or ca can come ? 

PS: If you do not understand some points my explanation do not hesitate to ask 
me again .
