MPLS Tab (Layer 4 only):
MPLS label:
Configurable in the range 16 through 1,048,575 (labels 0 to 15 are reserved).
Note: Composed of 20 bits which allows for the creation of over one million labels.
CoS:
Configurable in the range 0 to 6.
Note: This field is three bits in length and maps directly to IP Precedence TOS bits to provide Class of Service (COS).
S-bit:
Configurable 0 or 1.
Note: The S field is one bit in length and is used for stacking labels. This is important as it is used to indicate the last
label in the label stack.
TTL:
Configurable in the range 0 to 255. The default setting is 128 hops.
Note: Used to decrement the time-to-live counter.
Throughput Setup - MPLS configuration (Layer 4)
IP Tab:
Configures the destination IP address, source address and header fields.
IPv4
IP Type:
IPv4, IPv6
Source and Destination IP Address:
The source address is fixed to the IP address from the IP setup menu.
Subnet
: Subnet mask
Gateway
: Address of the network gateway
IP TOS (for Quality of Service testing):
Legacy TOS or DSCP
Legacy TOS :
The first three bits of the IP TOS field can be edited:
Precedence:
000 - Routine
001 - Priority
010 - Immediate
011 - Flash
100 - Flash Override
101 - Critical
110 - Internetwork Control
111 - Network Control
TOS Values:
1000 - Minimize Delay
0100 - Maximize Throughput
0010 - Maximize Reliability
001 - Minimize Monetary Cost
0000 - Normal Service
DSCP (Differentiated Services Code Point):
The first six bits of the IP TOS can be edited to provide
