This read-write Unsigned32 (0-255) specifies the full ToS-Byte value used for vPC peer-keepalive messages, where only the low eight bits are used, bit 0 is reserved, bits 1-5 represent the value in cVpcPeerKeepAliveTos, and bits 6-8 correspond to cVpcPeerKeepAlivePrecedence. Administrators can use this single object to set the combined ToS/Precedence byte directly, rather than configuring cVpcPeerKeepAliveTos and cVpcPeerKeepAlivePrecedence separately. For example, an admin who already knows the exact desired byte value from a network-wide QoS policy could set it here in one step instead of computing and setting the two component fields individually.
