in 0.001% increments, beginning at 0.002%. For details on
configuring a traffic load, see
“Configuring the traffic load” on
page 56 .
No Yes Flow Label If you are certain the routers
on the circuit support flow
labels for traffic prioritiza-
tion, specify the flow label
using a hexidecimal format
ranging from 0x0 to
0xFFFFF; otherwise, use
the default (0x0).
No Yes Hop Limit Specify the time after which
a packet can be deleted by
any device on a circuit as a
number of hops. The default
Hop Limit setting is 64
hops.
No Yes Next Header Specify the code represent-
ing the type of data carried
in the next header in the
packet using a hexidecimal
format ranging from 0x0 to
0xFF.
