Stefan,
The solution does not impart GTS or FRTS. It references a two rate
police schema by specifying either/or the CIR or PEAK.
The difference being CIR provides an average rate to police too, and
PEAK provides the maximum rate to police too (IOW, peak allows
bursting). Optionally you can set Bc and Be to specify the exact burst
values.
My question to GS is this:
Why would you use a two rate police scheme over a single rate police
scheme where IOS calculates Bc/Be, such as:
class-map match-any over1250
match packet length min 1250
policy-map police
class over1250
police 2500000 conform trans exceed drop
Int e0/1
Service in police
Service out police
Can someone please explain when one would be preferred over the other...
IOW, what wording would draw me to reach a two rate policing scheme?

Subject: GTS vs police cir vs FRTS
Could you please explain me the difference between this things ??
Task:
As an additional measure to decrease response time throughout your
network,
configure R5 so that packets over 1250 bytes are limited to 2.5mbps
outbound
on its interface e0/1.
solution:
class-map match-all ABOVE_1250_BYTES
match packet length min 1250
policy-map QoS
class ABOVE_1250_BYTES
police cir 2500000
here was used police cir. As far as I understood the difference between
Generic traffic shaping
and FRTS only one is that GTS could be applied not only on Frame-relay
interfaces but also on ethernet and others. Do I uderstand it
correctly??
Could in this example the GTS be used?? Here is the ethernet interface.
As
far as I understand the
policie cir command does the same thing ad GTS can. But GTS has more
options
to configure.
Do I understand correctly the difference between GTS, police cir command
(how it is called in another way??) and FRTS. Are there any other
differences.
Thank you for replies. This questions doesn't let me sleep.
