I?d like to highlight a problem we have configuring "Priority with Police" on a CiscoME3400 switch.
Following the indications in the configuration guide, once the service policy is applied to the interface on the switch the following error occurs:
class-map match-all GOLD
match ip dscp ef
class-map match-all BE
match ip dscp default
class-map match-all BRONZE
match ip dscp af21
class-map match-all SILVER
match ip dscp af11
police cir 512000
shape average 256000
shape average 2000000
ME3400_amps(config-if)#SERvice-policy OUtput SHAPING-OUT
QoS: Configuration failed. The configured rate is not achievable in hw within 1
% of configuration.
Closest value(s) are: 526315 bps, 500000 bps
The error does not occur while modifying the bandwidth in the policy map (for example to 256Kbps).
Similar errors have occurred during configurations which involve Class Based Shaping (QoS Parent-Child).
Are there specific indications or calculations for defining bandwidth parameters?
Look forward to receiving any suggestions on resolving these problems.
