Trunk strange problem


Fa0/1 trunk done for a 3 Switch 2950 switches (2 months of 2950 is the core switches to 4506), the other port has been used for vlan11 normal, which is an arbitrary one based on the need to port as the vlan10. At this time the 10-port serial terminal for the Orange network also broken links or ip address. However, the port will need to plan on links to other vlan, beacons were normal. Vlan10 also used in other switches normal. I do not know where the start to solve this problem.

Try to build a plane in the vlan10

Switchport turnk allow vlan 10

The above methods tried not! At 2 and 3 switches use show vlan results are as follows :
3 (in Taiwan Switch divided into 5, 9, 11 have links)

Switchport vlan turnk allow VLAN 10 through 10 can let the other pass VLAN

Switchport turnk allow vlan 10
You are not above the levels of 2950 VLAN10

Is it necessary? ? ?

Cross it will be received with the higher level of exchange is also its trunk, to show exactly vlan watched a v10 and v11, then it can not replace the original allocation vlan10 swap which Taiwan switchboard. Solve the problem.
I think the key issue is that it can discover the other vlan, the LAN Switch comes in 4, 5! Oh nothing!

Vlan port trunk permit seemed to be all of Canada.
Do not hit me! ! Ha ha

At this time the Port of Orange does not mean that you are the VTP VLAN 10

VLAN switches can learn, you can add your own needs manual VLAN oh

Answer : I have the eighth floor LAN Switch Lane has been used in 40 to Taiwan the trunk switchport mode trunk so that the problem will be 4, 5. Not like this.
A 9, 10 : Building on its switchboard level, all the vlan vtp all have to recognize it here only two, it is the key to why not learn while other will be able to learn, and I have appointed a three-tier exchange Lane v10 and v11, v10, and he learned a v11. terror is the future use if needed vlan seemed to be moved to other secondary switches to learn about.
Vlan hand but do not know it can be added to the other switches and LAN Lane vlan whether the same can not use the normal tried.
Thank you, I have time to go try.

Second, the solution is the 10th floor
