NAS-Port-ID format enhancement

We've introduced a new NAS-Port-ID format for RADIUS server access request. The new NAS-Port-ID format is S-VLAN<concatenated 0's>C-VLAN:S-VLAN-C-VLAN. For a C-VLAN, if the number of digits is less than four, precede it with zeros. For example, NAS-Port-ID for S-VLAN 72 and C-VLAN 82 is 720082:72-82. You can configure the fixed-size-inner-tag and fixed-size-outer-tag statements at the [edit access profile profile-name radius options nas-port-id-format concatenated-vlan-tags] hierarchy level.
