[c-nsp] 6509 Interface Question

[Tim Stevenson]

There is no way to reassign that vlan, except by de-configuring the L3 
interface, assigning the (old) internal vlan to the SVI etc that you 
wanted, and then redefining the L3 interface.

The vlan allocation policy is a good suggestion, though you could then end 
up with some high numbered vlan that you need for on-wire use. But at least 
the internal range is not taken right from the middle of the 4K range.

Note that changing the vlan allocation policy requires a reboot.
