1480963 - Issue seen only when the cookie 'bm_clear_vmi' is set to empty string.
1486679 - VxLanIdentifier max range changed to 16777215
Closes-Bug: #1480963
Closes-Bug: #1486679

JSON.parse is not supposed to be used to parse string, but object.
Hence using simple string comparators as getCookie() returns string.

Also changed max range of vxlan_identifer to 16777215 as per request in the bug 1486679
