Configure it as a trunk ie.

int fa0/4

switchport trunk encapsulation dot1q

switchport mode trunk

Jon

i have done that but will this be it only ??? will it prevent it from becoming a access lnk ???

From Cisco doc (4500 config) -

"If you enter trunk mode, the interface goes into permanent trunking mode and negotiates to convert the link into a trunk link even if the neighboring interface does not approve the change."

Jon

thanks for the confirmation !!!
