length field specifies the total length of all TLV tuples. The JUNOSe software enterprise
number is 4874 (0x130a.)
The format of the Layer 2 Circuit ID type field (type 1) is hexadecimal. The data field
length of a normal non-stacked VLAN is 2 bytes, with the VLAN ID occupying the 12
low-order bits of the value; the 4 high-order bits are 0. The data field length of a
stacked VLAN is 4 bytes, with the SVLAN ID occupying the 12 low-order bits of the
2 high-order bytes, and the VLAN ID occupying the 12 low-order bits of the 2 low-order
bytes; the unused bits are 0. The data field length of a VPI/VCI is 4 bytes, with the
VPI occupying the 8 to 10 low-order bits of the 2 high-order bytes, and the VCI
occupying the 16 bits of the 2 low-order bytes; the unused bits are 0.
The format of the UPC data field (type 2) is hexadecimal; its data field length is 1
byte, with the UPC occupying the 4 low-order bits of the value; the 4 high-order bits
are 0.
Example 1—The Vendor-Specific suboption for a VLAN ID of 2468 (0x09a4) and a
UPC of 5 is formatted as follows:

Example 3—The Vendor-Specific suboption for a VPI/VCI of 123.45678 (0x7b.0xb26e,
format <VPI>.<VCI>) and a UPC of 5 is formatted as follows:
09 0e 00 00 13 0a 09 01 04 00 7b b2 6e 02 01 05
| | | | | | | | | |
