3750 qos on routed interface

I have 2 3750G-24 as the core of my voice/data network. I have 2 vlans (voice,data) and it seems like when I cross the routed interfaces (virtual vlanX interfaces) I lose my qos tagging. I have tried route-maps and policy maps but they are not working (the policy maps are not supported on virtual interfaces)
Anyone with a solution?? I have searched cisco.com and unless i am blind, have not found what I am looking for.

Here is the edge switchport config-
End user port-----

switchport access vlan 50
switchport trunk encapsulation dot1q
switchport trunk native vlan 50
switchport mode trunk
switchport voice vlan 10

end
Here is the core switch-

QOS on 6500 routed interface

All of the QOS configuration guidance I've seen in the documentation on this website refers to 6500 switched interfaces (switchport mode access/trunk).
Is the QOS configuration different on a 6500 routed interface. For instance on an interface between two core switches in a routed (Layer 3) core?
I have already reviewed all of the IOS-related 6500 Cisco documents I could find, and the latest QOS SRND with no luck finding info on this issue.
Thanks

3750 QoS - egress interface

Please guide me to understand the 3750 QoS mechanism.
Q1) DOC say "priority-queue out" is ignore shape and share command. is it meaning always give priority to cos=5(or dscp=ef) traffic regardless the shape command?
Q2) I want to give 10% guaranteed bandwidth to voice traffic. what's best command in the 3750 egress interface? shape only or combine with priority-queue?
Q3) Any doc explained the output for the command "show mls qos interface f1/0/1 statistics"? the meaning of the each field.
Thanks in advance,

Hi,
1. That is correct. The expedite queue is a priority queue, and it is serviced until empty before the other queues are serviced. This has the potential to hog all the bandwidth on an interface....
2. I would use the priorty-queue command as it will give the best jitter and latency characteristics for your voice traffic. If you want to limit this bandwidth, you should do it via policing on ingress interfaces.
3. Check out this link:

Router Interface (7304 NSE100) QoS Input Scheduling

Guys,
I had great feedback on the Switch input scheduling question last week. Many thx to all online (and my colleagues at work) :)
If you can apply input scheduling on a switch port, ie the SP or default queues, can you apply input scheduling on a router interface?
switch
input-q----------PFC----------output-q
router
input-int---------cef-or-rp----------output-int
At the moment, most QoS for a router is done (in my expreience) on outbound scheduling, ie setting a CBWFQ bandwidth or priority and setting this policy-map outbound on the router egress interface
Should we be doing it inbound for traffic coming into a router interface before the packet gets cef switched (or sent to the RP for process or fast switching)?
So if two packets come into the router interface at the same time, based on a DSCP value, we should schedule a voice packet to be processed by CEF switching (or the RP) before an email packet?
I am just applying the switch methodology that I learned about last week to a router device. I know all routers have different archetectures, so will probably be spefific to a platform. I am using NSE100s (PXF based) on a 7304 platform.
Kindest regards,
Ken

Just to add i picked this from some site
GSR:
Engine 0: (Quad STM-1 POS/ATM, single STM-4 POS/ATM and others)
Engine 1: (single GEth, 8 FEth, DPT 2XSTM-4)
Engine 0 and 1 support CAR in sw; MDRR: in Engine 0 in sw
Engine 2: STM-16, Enhanced Quad OC-12/STM-4 Packet-over-SONET/SDH - 4 ports, MPLS-capable -, 8 and 16 STM-1, 3 GEth, Enhanced OC-48/STM-16 Packet-over-SONET/SDH.
no support of CAR, PIRC in hw instead; WRED in hw; MDRR in hw
(See also Quad OC-12/STM-4; Rel. Notes 12.0 S )
Engine 4: speed greater than 2.5 Gbps,
CAR, WRED, MDRR in hw
Note: no class-based shaping on GSR
But it supports DTS

Extending VLANs across routed interfaces

Hello;
I'm trying to create a L3 core network. The core equipment will be Cisco 3750 enhanced. My idea is make each link between core 3750 a routed interface, with /30 IP addresses.
The problem is the customer needs some VLANs extended across the full enterprise. Is there any way to encapsulate the VLAN inside routed interface?
Thanks in advance.

I realize this thread is 5+ years old, but I feel like commenting anyway.
If you want to encapsulate the vlan across that link, you won't be able to use routed interfaces. You will need to use a layer 2 trunk(dot1q). Therefore, I wouldn't bother with the /30 addresses unless you want to monitor that specific link by IP. In that case, use a special VLAN just for those two interfaces and put your /30 addresses on the vlan interfaces.
If you want fast fail over on a layer 2 link, well then, use Rapid STP. The goal should be to get rid of those flat VLANs that span the core and switch to your original plan of routed interfaces using EIGRP or OSPF.

You need to populate the organization_id or organization_code in bom_inventory_comps_interface.
Here is a minimal insert

I press reset and now i can't get into router interface?

Yestoday i was just experimenting with my router. I set up a restriction for 12am to 12:05am to see if it will block my sister's internet just for the fun.
However it did not work.
Today my internet was slow because of my sister's laptop. Probably downloading some soft of content. I decide to press the reset button therefore her connection would be taken off.
However now i want to fix that. I understand how to get into my router's interface:
-By going to my computer and then typing 192.168.1.1 on top...
-Yestoday when i did that it worked. I was able to get into router interface, but now i can't. It gives me "cannot find server"
I don't understand why i can't get into my router's set up~
Can this be fixed?

it might be that the reaosn why you're not accessing up the router's set-up page is because the computer connected to it is not getting a valid IP adress already...
to check this...
go to START, then RUN
type in cmd
in the command line, type in ipconfig
take note of your IP adress... that's the computer IP adress..
Now, take note of your default gateway... that is equivalent to your router's IP adress...
in the same window, type in (ping default gateway #) ping 192.168.1.1 . if it replies, then your router's interface should be able to open up
launch internet explorer, then type in http://192.168.1.1

Network Routings not imported through "Bill and Routing Interface" program

Hi,
I wanted to import Network routing to Shop Floor Manager hence I am using bom_op_routings_interface and then I am running "Bill and Routing Interface" program. But import program is errored with "You do not have access to items of type standard, so you may not be able to insert, update or delete routings ot this item type".
Highly appreciate if any one clarify why this error is issued by Import program.
Thanks in advance.

Please see if the solution in (BOM API Bom_Rtg_Pub.Process_Rtg is not Creating or Updating Maintenance Routings [ID 761976.1]) helps.

I am wondering if it is possible to configure one ACE context to support both routed and bridge interface?
I would like to have a bridge-mode context but in the same time I would like to have a separated OOB interface for management.
If it is possible how they could interact to each other?
Thank you in advance for any answer

Hello
We've just tried to configure bridged and routed interfaces at the same time in the lab and we've had a problem.
When we added the def gw for the bridged config we noticed that we had an issue with the traffic src by the rservers in the routed config.
When we deleted the new def gw, the problem disappeared.
I am attaching the lab config.
When we added to it the following line
ip route 0.0.0.0 0.0.0.0 10.1.1.163
reals B1-B10 could not communicate to the outside world.
Do you know why it does not worked and what could we do to fix it ?
Thank you in advance.

Redundant Routed Interfaces

Hi,
Is there anyway to create redundant inerfaces on a single router?
Essentially, what I am trying to do is to imitate HSRP but on a single router.
Whenever you try to add a second interface that exists within the same network as an existing routed interface, the IOS will prevent it.
Can you use Bridge Groups? Or maybe something funky with secondary interfaces?
Other suggestions?

Hi
i feel u need something line with backup for ur primay interface .. if yes have u tried backup interface option in ur router ??
if not can you look onto that option and check whther it fits onto ur requirement??

Router Interface Cards - Routing Feature

Dear Team,
I have a Cisco 3945 Router and have all the slots available with me. The interface card that I am looking for should have the same functionality as HWIC-2FE.
I need a 4 or 8 port Routed Ethernet Card. I looked for "VWIC3-4MFT-T1/E1" interface card as I was unable to find 8 port card.
Please let me know if this card can be used as a Routed Interface Card (I need to terminate different ISP Links on this card).
Regards,
Farhan.

Believe the module you mention provides serial ports, not Ethernet ports. Also believe it supports routing.
Higher density Ethernet cards often support routing via VLANs (you can dedicate a VLAN per port), but not as routed ports.
What you also do, if you have VLAN capable switch, use subinterfaces on a router port to a trunk port on the switch.

3750 qos - buffer size

I am putting together a VOIP qos config for a number of different switch types on of which is the 3750. We have a load of these switches an although the SRR method is different to me I think I have a handle on it.
The software config guides make numerous mention of configuring the queue sizes and weights etc in terms of buffer space percentage.
I believe that the amount of space available for egress and ingress buffers is fixed so I have a simple question.
What is the size of the total available buffer space either in bytes or number of packets ?
I cant find this anywhere. Seems to me that trying to allocate buffer space and weights without this info is more or less guessing.
I have the software config guide which is quite good but seems to leave out this kind of info, can anyone suggest a more complete document which may help ?
Many Thanks
Shaun

two things...first things first:
1) see if AutoQoS (introduced in 12.2(15)T) will work for you to create a baseline QoS requirement...this may allieviate your need to crunch so many numbers/scenarios before you actually know what QoS your network requires.
2) the queues can be shared by percentage or shaped by bandwidth.
see the following links for 3750 QoS sharing & shaping:
