Server Layer Infor. ERO sub-object.
from
.
This sub-object can be used for specifying the detail
server layer information of a server layer path, e.g. the switching
capability and encoding of the server layer path.

The type of SERVER_LAYER_INFO sub-object is to be assigned by IANA.
L: The L bit SHOULD NOT be set, so that the subobject represents a
strict hop in the explicit route.
Switching Capability (8 bits): see [RFC4203] for a description of
parameters.
From RFC 4230:
The Switching Capability (Switching Cap) field contains one of the
following values:
1 Packet-Switch Capable-1 (PSC-1)
2 Packet-Switch Capable-2 (PSC-2)
3 Packet-Switch Capable-3 (PSC-3)
4 Packet-Switch Capable-4 (PSC-4)
51 Layer-2 Switch Capable (L2SC)
100 Time-Division-Multiplex Capable (TDM)
150 Lambda-Switch Capable (LSC)
200 Fiber-Switch Capable (FSC)
Encoding (8 bits): see [RFC3471] for a description of parameters.
Optional TLVs: Optional TLVs may be included within the object to
specify more specific server layer path information (e.g., traffic
parameters).
This sub-object MAY be added immediately behind the node or link
address sub-objects of the two edge nodes of a service path.
