Hi,
I have an issue with two of our BIP links.
On our HQ BIP link and on our High Availability BIP link when you enter the Service-Policy command, the command is accepted but when you do a sh run and look at the running config, you cannot see where the service-policy is applied.
The running config is:
interface ATM2/0.1000 point-to-point
description HQ BIP Link
bandwidth 10000
ip address 20.40.60.80 255.255.255.252
no snmp trap link-status
pvc 0/100
vbr-rt 10000 8000 200
oam-pvc manage
oam retry 3 3 5
encapsulation aal5snap
transmit-priority 1
!
I applied the following under pvc 0/100 and still cannot see it applied.
service-policy output WAN-OUT
I copied in the WAN-OUT config:
policy-map WAN-OUT
class RTP
priority percent 45
class SKINNY
bandwidth percent 5
class CITRIX
bandwidth percent 20
class PRINTER
bandwidth percent 5
class MGMT
set dscp af31
class class-default
bandwidth percent 15
random-detect
What can I do to apply this?

Which exact router and IOS ?

Hi,
I ran a sh ver:
Cisco IOS Software, 3800 Software (C3825-ADVENTERPRISEK9-M), Version 12.4(5a), RELEASE SOFTWARE (fc3)
ROM: System Bootstrap, Version 12.3(11r)T2, RELEASE SOFTWARE (fc1)
System image file is "flash:c3825-adventerprisek9-mz.124-5a.bin"
Cisco 3825 (revision 1.0) with 219136K/43008K bytes of memory.
Processor board ID FCZ094271C7
2 Gigabit Ethernet interfaces
31 Serial interfaces
3 Serial(sync/async) interfaces
1 ATM interface
1 Channelized E1/PRI port
1 Virtual Private Network (VPN) Module
DRAM configuration is 64 bits wide with parity enabled.
479K bytes of NVRAM.
62592K bytes of ATA System CompactFlash (Read/Write)
If you need any more info, please let me know
Thanks

Can you try, like 12.4(3j) or something off 12.4T ?

I don't see a bandwidth statement for class MGMT?
On many platforms/IOSs, there's a default explicit bandwidth reservation of 75%.

Hi,
The link is 10MB and under the ATM interface it is configured for 10000
THe 10MB BIP into HQ has a Carrier Premium Service of 75%
The 10MB BIP into High Availability site is Premium 2 and a service of 60$
Are you suggesting changing the WAN-OUT to total 75%
policy-map WAN-OUT
class RTP
priority percent 40
class SKINNY
bandwidth percent 5
class CITRIX
bandwidth percent 15
class PRINTER
bandwidth percent 5
class MGMT
set dscp af31
class class-default
bandwidth percent 10
random-detect
Will the MGMT not get the remainder of the bandwidth?
06-09-2009 05:43 AM
Fact is, whatever the BW, if the command doesn't show in config, there is a problem.

"Will the MGMT not get the remainder of the bandwidth? "
I'm unsure what MGMT class will be considered by the service policy.
On most platforms/IOSs, when using explicit bandwidth percentages, you can't define more than 75% without changing the default reserved bandwidth.
Off the top of my head, I don't recall whether an explict bandwidth defined for class-default also comes out of the max reserved allocation.
What I suggest, unless you really need X% for a non-LLQ class, you switch to bandwidth remaining percent. This then allows up to 100% being defined, regardless of max reserved setting. I also suggest you define an explict bandwidth for class MGMT.
BTW, if you're not seeing any error when you apply the policy, but the policy isn't accepted, you might also check your syslog for an error message.

The two BIP circuits have Premium or Premium 2 class of service, which only allow for 60% and 75% (respectively) of reserved bandwidth (in line with Cisco default maximum of 75%) according to our Carrier.
The HQ site has a Premium 2 which is 75%
THe HA site has a Premiun which is 60%
What I am going to do is change the WAN-OUT to:
policy-map WAN-OUT
class RTP
priority percent 40
class SKINNY
bandwidth percent 5
class CITRIX
bandwidth percent 15
class PRINTER
bandwidth percent 5
class MGMT
set dscp af31
bandwidth percent 5
class class-default
bandwidth percent 5
random-detect
I think that the WAN-OUT service-policy that is configured on the BIP routers would (if applied) oversubscribe the class of service.
Thanks
Anthony.
