Subject Re: [Discuss] Support for non-contiguous vlan ranges.
Date Wed, 06 Mar 2013 07:20:09 GMT
The changes will be atomic.
before removing any range we need to check if any of the vlans in the range are in use. The
operation will fail if some vlans in the remove range are in use.
i.e. if E=100-200 (existing) U(used)=101,121,131
and remove=100-201 we do not remove this range as 101,121, and 131 are being used.
if the admin wants to remove the reset of the range leaving the used ones he can say 
remove 100-100, 102-120, etc

I will update this in the FS.

Bharat.
