!!!Storm control is working.!!! Would still be nice to know why policing
does not work with a policy-map ??

UMMM. this kinda gives me an idication that no packets are being matched
:) dont know why tho as yet. i will keep plodding on ....
Tried a new policy map matchine an ACL....
!
class-map match-all port13
match access-group 10
!
access-list 10 permit any
!
policy-map POLICE
class port13
police 3496000 8000 exceed-action drop
!
!
interface FastEthernet0/13
switchport access vlan 21
no ip address
load-interval 30
service-policy input POLICE
spanning-tree portfast
!
Cat1_3550#sh policy-map int
service-policy input: POLICE
class-map: port13 (match-all)
0 packets, 0 bytes
30 second offered rate 0 bps, drop rate 0 bps
match: access-group 10qm_police_inform_feature: CLASS_SHOW
class-map: class-default (match-any)
0 packets, 0 bytes
30 second offered rate 0 bps, drop rate 0 bps
match: any
0 packets, 0 bytes

Subject: Rate Limiting on a switch port
One more question for the day.
I have just been asked to limit a switch port to a max rate of 2,000,000.
SO I think, right, this is not so bad.
I try the following Police, and unicast supression, cant use CAR or TS on
3550 so it looks) with the following results :- when sending a 5MB stream
from an attached PC.
Any ideas? - Sorry, its my second post today :) QoS day!
