etherchannel issue

after1111
Level 1
Level 1

I've configured etherchannel on my switch but i can only ping the default vlan 200, but not other VLANs. This is a layer 3 switch - routing is enabled.

Any ideas?

interface Port-channel1
switchport trunk native vlan 200
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 300,400,500
switchport mode trunk
!

interface GigabitEthernet1/0/1
switchport trunk native vlan 200
switchport trunk encapsulation dot1q
  switchport trunk allowed vlan 300,400,500
switchport mode trunk

channel-group 1 mode on
!

interface GigabitEthernet1/0/2
  switchport trunk native vlan 200
  switchport trunk encapsulation dot1q
   switchport trunk allowed vlan 300,400,500
  switchport mode trunk

channel-group 1 mode on

!

end

!

switch1#show etherchannel summary

Number of channel-groups in use: 1
Number of aggregators:           1

Group  Port-channel  Protocol    Ports

I noticed the protocol does not show (is this normal?). Im running LACP between the switch and the Dell server.

    You are not running LACP if you have the port channel set as on .  It would have to read "channel-group X mode active or auto "  to be using LACP.
