can any netpro share with me what are the difference between trun allowed vlan and native vlan .
your reply will be highly appreciated.
Firstly you need to decide whether you want to run the link as a trunk link or not. If you do then do as Narayan says and configure switch 2 port as a trunk.
If you don't then as Edison has said, switch 2 will send vlan 269 packets only down the link and these will not be tagged because switch 2 port is configured as an access port and not a trunk port. Packets sent down an access port are not tagged.
So if you want to remove the error message you will have to make the native vlan (ie. the untagged vlan) on the trunk port of switch 1 to be vlan 269. That is the only vlan you can use because that is the only vlan coming down the link from switch 2.
I would recommend deciding whether or not you want this link between the 2 switches to act as a trunk link or not.
