Hi Everybody:

Im conecting a phisical trunk, between switch Dell PowerConnect 5324 and Cisco 2811 Router, please see the attachment topology, I can't not ping between the PC A and PC B, I will show the configs:

The config in the router CISCO:

!
interface FastEthernet0/0
description Cisco to Trunk DELL
no ip address
duplex auto
speed auto
!
!
interface FastEthernet0/0.2
description VLAN 2
encapsulation dot1Q 2 native
ip address 200.71.155.193 255.255.255.248
!
interface FastEthernet0/0.3
description VLAN 3
encapsulation dot1Q 3
ip address 201.249.204.153 255.255.255.248
!

Config DELL POWERCONNECT:

Configuring VLAN Trunk in Ethernet G23 :

interface ethernet g23
switchport mode trunk
switchport trunk allowed vlan add 2,3
exit

ADDING VLAN 2 AND 3:

enable
configure
vlan database
vlan 2
vlan 3
exit

Configuring Ports E2 , E3 in VLANS 2, 3 respectivily:

interface ethernet e2
switchport mode access
switchport access vlan 2
exit

interface ethernet e3
switchport mode access
switchport access vlan 3
exit

copy running-config startup-config

Could you tell me what is missing on my config? Thanks in advance.

I'm not familiar with that make of switch but have you made vlan 2 the native ie. untagged vlan on the switch ?

If not then it may be easier on the 2811 to simply change -

int fa0/0.2

encapsulation dot1q 2 native

to

int fa0/0.2

encapsulation dot1q 2

ie. remove the native keyword and retry.

Thanks you, I am going to do that, it is true, because I dont configure native VLAN on DELL switch, may be this is the problems cause.
