This attribute indicates the round trip delay of the link in
milliseconds. This value represents a nominal delay for
connectionless traffic. Connectionless traffic is biased away from
trunks carrying path-oriented traffic by increasing this value. The
value of this attribute is a function of the percentage of reserved
path-oriented bandwidth and takes a maximum value of 1500 msec
for 100% path-oriented trunks. If a delay override is specified, it
will be used instead.
