Destination Address /

For IPv6 or GTP.IPv6 addresses, enter a valid IPv6 address in

 

 

 

 

 

 

any allowed IPv6 address format. For example:

 

 

 

 

 

 

1080::8:800:200C:417A

 

 

 

 

 

 

Note See RFC 2373 for valid text representations.

 

 

 

 

 

 

For MAC address, enter hh hh hh hh hh hh, where hh is a
