How to Cisco 2611XM with 2924XL Switch Test Environment

By info ·
Hi All,

I am setting up a test environment and can't work out why the VLAN configuration is not working.

On Cisco 2611XM Router:

vlan database
vlan add 5


interface FastEthernet0/1.1
description vlan5 test
encapsulation dot1Q 5
ip address
ip nat inside
no cdp enable


On Cisco 2924XL

vlan database

Name: vlan5-test
Media Type: Ethernet
VLAN 802.10 Id: 100005
State: Operational
MTU: 1500


interface FastEthernet0/5
description dot1q5 test
switchport trunk encapsulation dot1q
switchport trunk native vlan 5
switchport mode trunk
spanning-tree portfast
no cdp enable


Host plugged into port 5 on switch has IP Address but cannot ping the router, even though the switch shows the VLAN is established:

Switch#show interface FastEthernet0/5 switchport
Name: Fa0/5
Switchport: Enabled
Administrative mode: trunk
Operational Mode: trunk
Administrative Trunking Encapsulation: dot1q
Operational Trunking Encapsulation: dot1q
Negotiation of Trunking: Disabled
Access Mode VLAN: 0 ((Inactive))
Trunking Native Mode VLAN: 5 (test)
Trunking VLANs Enabled: ALL
Trunking VLANs Active: 1,5
Pruning VLANs Enabled: 2-1001

Priority for untagged frames: 0
Override vlan tag priority: FALSE
Voice VLAN: none
Appliance trust: none

Maybe I am tired and missing something here, but it refuses to work.

Any ideas ?
