CBWFQ with Q-in-Q (ME-3600X-24TS-M)

Hi!
I wonder if it's possible to run mark inbound traffic on L2 interfaces and then use CBWFQ on the q-in-q trunk's for bandwidth management or
do you need to have routed interfaces inbetween the two ME3600 switches to be able to use CBWFQ?

Hi Juan,
Yes that is correct.
You can now enable the additional TenGig ports with cmd: “sdm prefer 4” (for two additional 10GE ports) or “sdm prefer 3” (for 1 additional 10GE port).

Licensing Inquiry for ME-3600x and ME-3800X

I would like to know how the licensing works for ME-3600X and ME-3800X.
For 3600X
1. What is the base license for Cisco ME 3600X-24TS Ethernet Access Switch -ME-3600X-24TS-M?
2. If I want to upgrade the license to Advanced Metro IP Services using L-ME3600X-A, do I need to have L-ME3600X-LIC= to activate it?
For 3800X
1. What is the base license for Cisco ME 3800X-24FS Ethernet Carrier Ethernet Switch Router - ME-3800X-24FS-M?
2. What is the difference between L-ME3800X-A and L-ME3800X-I-A?
3. What is METRO IP2 AGGREGATION SERVICES?
4. If I want to upgrade the license to ME3800X-S do I need to have L-ME3800X-LIC= to activate it?
For software options
1. Do I need to include this on the first purchase? I mean, assuming I have the upgrade licenses and the smartnet services for 3600x and 3800x.

Cisco Network Assistant v6.0 & C2960X-24TS-L Display Problem

Hello,
I have recently updated to CNA 6.0 and added a C2960X-24TS-L switch to a small ten switch LAN. When viewed in the CNA Front Panel View, the active ports do not show as active (no green outline). All other switches on the LAN (mostly 2960-24TC and 2960-S series) display properly. If the C2960X-24TS-L is viewed through its web interface, all the active ports are properly shown with green highlight. The C2960X-24TS-L is running 15.0(2)EX5.
I also noticed that when viewing the switch mode LEDs in the web interface, the SYST, STAT, and MSTR are shown (properly) as illuminated, whereas in the CNA Front Panel View, only the STAT LED appears illuminated.
Could someone advise me as to whether this is a known problem with CNA V6.0 ? If so, is there a release update expected soon? If it is not a CNA problem, is it correctable through a CNA setting or perhaps a OS update?
Thank you,

I can see active port on main stack switch, but not members

Random-detect with MPLS

Has anyone implemented CBWFQ with MPLS and used random-detect with any of the classes/queues? Is there anything special about random-detect that allows it to drop TCP v. UDP when doing label switching?

I'm basically referencing that no other headers are looked at when doing label switching. Therefore, when applying random-detect to a queue we can not easily have TCP seperated from all other traffic to maximize our chances of dropping a TCP packet to slow down the source. It appears that the commonly accepted method is to set the mark probability denominator high enough and make sure that the majority of your traffic is TCP.

K9N Platinum lock ups

Hi Guys, I am building a new pc and I am having lots of problems. The main one being the pc will lock up after a few mins of being on. I have read it could be a memory problem, but I am not sure.
The System is....
CPU: AMD X2 Dual Core AM2 Athlon 64 3800
Ram: OCZ 1GB Kit (2x512MB) 240Pin PC2-6400 800MHz Dual Channel GX XTC Gold
Power supply: Enermax 535Watt Power Supply ATX12V & EPS12V for EEB, CEB
Video Card: XFX 7900GT PCI-E 256MB DDR3 DUAL DVI
and the K9N motherboard.
Is the Ram an issue? Would I be better off exchanging the ram for something else? Could anyone reccomend ram that will work with this board?
Thanks a lot for your help guys.

Thanks for the suggestion, unfortunately I have just tried that but its still locking up.
I have had a look in the bios to set all the memory settings manually, though I am not sure what I set to what. Apparently the corsair ram has 5-5-5-15 timings but I do not know what these relate to in the bios.
I guess the CAS#Latency(TCL) should be set to 5 then I'm not sure what to do. The options I have are
Min RAS# Active Time(TRAS) With the option of 5CLK to 18 CLK (This is set to 15 as mentioned above by Kakarocht)
RAS# Percharge Time(TRP) With the option of 3CLK to 6CLK (I guess this is one I should set to 5, currently at Auto)
RAS#to CAS#Delay(TRCD) With the option of 3CLK to 6CLK (I guess this is one I should set to 5, currently at Auto)
ROW to ROW Delay(TRRD) With the option of 2T to 5T (I guess this is one I should set to 5, currently at Auto)
ROW Cycle Time(TRC) With the option of 11T to 24T (Currently set at Auto)
There is also
Bank interleaving which is enabled
CMD-ADDR Timing Mode which is set to 2T
Software Memory Hole which is Enabled
Sorry to be a pain and keep asking all these questions, but this is really confusing me.
Thanks yet again

Questions about the bandwidth.

Let me explain my existing environment
as follows :
- I have two 2801 routers with
C2801-SPSERVICESK9-M IOS
- Each router has Four-port FXS
connected to the phones
- The bandwidth between these routers
is 256 Kbps ( Leased Line )
My qouestions are as follows :
1. How many bandwidth are a call
comsumed ( per call ) ?
2. To ensure that the bandwidth of
VoIP is not excess the maximum
bandwidth of leased line. And to
ensure that the priority of VoIP
is always higher than the priority
Data. I will use RSVP and CBWFQ
with ip precedence. Are these
features suitable for the
situation ?
Thanks!! : )

hi
regarding bandwidth consumption it depends upon the kinda codec which you are gonna use up there.
ofcourse g.729 does uses minimal amount of bandwidth and also that get reflects in ur quality.
If you are gonna used some kinda RTP compression out there that can always reduce the packet length drastically to lesser size which will be easier as well u will be able to use the B/W effectively .
regarding the priority part you can always use up LLQ to have high priority for your VOICE traffic and deploy CBWFQ for your data traffic.
if u wanna have sample configs would suggest to do a search in cisco about the same ,if u need further assistance do revert..

In order to match these ports, the BW is a 128 kbps; and this problem only happens on an RPM with PPP, not with a normal router with CBWFQ with FR; everything seems to be OK, but the costumer`s config also seems OK..on an ACL that i put on the costumer`s Multilink i`m seeing that the packets are arriving matched; but the problem is still alive...any suggestions for test????, i`ll appreciate it...

Need help understanding IP Precedence traffic types

I was reading through the different IP Precedence values and most seemed to be fairly straight forward, but I'd like to make sure I have my facts correct. According to the list below, IP Precedence treats traffic lowest to highest priority with numbers 0-7, respectively, is that correct?
Is it a matter of drop rates increase with the IP precedence value then as well?
What type of traffic would fall under 4? I've never heard of Flash, or Flash Overide type traffic, a little clarity would be much appreciated.

Interface fair-queue treats IP Prec marked traffic differently. As interface FQ was the default on serial interfaces E1 or slower, you might consider it as "automatic". (NB: FQ within pre-HQF class default, works the the later interface WFQ.)
Explicitly configured QoS WRED (on interface or within CBWFQ), with defaults, treats IP Prec marked traffic differently.

Somes questions about WFQ and Per-Hop Behavior

Hi !
I'm currently self studding for my CCNP ONT certification Exam.
I read the official certification guide for this exam from Cisco Press. But, some point are still confuse for me :
1- Why WRED is most deploy on cores devices then all devices in Enterprise Network ? (The author saied :"Because WRED is usually applied to network core router....") And which implementation of congestion management system I should deploy on none core device, because thoses can also experience congestion in some point of the day and tail drop should be avoid also on thoses (distribution and access devices) devices also if I understand correctly ?
2- I understand WRED is an evolution of RED. Is still exist some reason to choose to use RED over WRED ? If WRED is available in device, is the RED is also available ? In my book in the example it say to activate WRED the command is RANDOM-DETECT, what about to activate RED ?
3- I'm confused about "class selector Per-Hop Behavior", if I'm understand correctly, We have 8 sub-classes "class selector Per-Hop Behavior" for each : Default Per-Hop Behavior, Assured Forwarding 1 to 4, and Expedited Forwarding, where the lowest value have higher probability to be drop. The class "class selector Per-Hop Behavior" work in the inverse of there parent where the highest value have higher probability to be drop.
in the exemple (copied from the book) how the preference of dropping is selected :
random-detect dscp-based
random-detect dscp af21 32 40 10
random-detect dscp af22 28 40 10
random-detect dscp af23 24 40 10
random-detect dscp cs2 22 40 10
I'm correctly understand how I should interpret the "random-detect dscp af" in comparaison of each other but, I don't understand where the I should place the "random-detect dscp cs2" with regard to the others.
Thanks a lot in advanced for your help !
Excuse my Engliash, but I'm a French people !

Hi,
The main difference betwwen PQ and LLQ is this.
PQ: Exclusively starves other traffic while serving packets in its queue. Infact PQ is so greedy, other traffic may never get serviced as long as there are packets in the PQ.
LLQ: It combines the bandwidth reservation of CBWFQ with PQ.
LLQ uses Policing to ensure that Bandwidth configured for PQ is not exceeded and when exceeded, drops the packets and then service the non-LLQ queues.
Hence LLQ ensures guranteed badnwidth only to the contracted amount.
Eg if a LLQ has 30kbps of bandwidht reserved. This can take a single G.729 call. If a 2nd call comes in, the policer will discard packets and both calls will sound bad. Hence its important to use CAC to limit the number of calls allowed to that configured for LLQ bandwidth, so the policer does not drop packets.
LLQ traffic uses the EF Diffserv PHB.
The EF PHB has 2 components.
1. Queueing to provide low delay, jitter or loss plus a guranteed bandwidth.
2. Policing to prevent EF traffic/LLQ traffic from starving other traffic of bandwidth.
So in summary, PQ will always treat PQ traffic firts and will starve other traffic of bandwidth
LLQ on the other hand will serve LLQ queues to the tune of bandwidth configured for them and then service other queues too.

1130AG POE problem

1130AG AP, connected with Cat6 cable to Nortel 460-24T-PWR switch.
Switch is configured to supply up to 16W power to each port. I've tried 1130 in several ports and switch displays that it is delivering 4.5W to unit in any port I try.
1130 web admin page says that inline power source insufficient to enable radios. Documentation says that AP needs to draw 12.5W.
Both units are the default configs for POE, except I disabled POE on switch ports that don't need to use it.
Both sets of documentation claim that no other config is necessary. Supposedly, I should be able to connect it and it works, yet... it doesn't.
Anyone have this kind of setup that can tell me what needs changed?
TIA
Rick

IOS is version 12.3(8)JA
The only option in the IOS command is:
power inline negotiation [injector | prestandard] source
I've tried a couple of different cables, Cat5e and Cat6.
On the web admin page, there are two options for the power source - Negotiation or Pre-Standard Compatibility. When I set it to Negotiation, the display says "NOT YET DETECTED" although the switch still shows the unit drawing 4.5W of power. Setting to Pre-Standard Compatibility displays "LOW_POWER_CLASSIC_NO_INJECTOR_CONFIGURED" with the same power consumption on the switch.

802.1x Failed Authentication with WS-C3750G-24T

Hi,
I have already set up a lab comprising of 1x2950-24 switch, 2x3750-24T in stack mode and 2x MS Domain Controller with AD 2008 Servers and NPS enabled (Domain level 2008). I use NPS as a Radius Server. I am trying to test the 802.1x framework in two scenarios.
1.     I use as client a domain laptop with Windows XP SP3 with the embedded 802.1x MS supplicant. As authenticator use the 2950 switch and as authentication servers I use the two NPS integrated in MS DCs. Everything is working fine as I expected with basic configuration guidelines from Cisco & Microsoft.
2.      I use as client a domain laptop with Windows XP SP3 with the embedded 802.1x MS supplicant (the same as before). As authenticator I use the 3750 Stack switch and as authentication servers I use the two NPS integrated in MS DCs (the same as before). I have configured the supplicant for both machine or user authentication in both scenarios. However the client never pass the authentication in the second one. I disconnect and connect the same supplicant in the 2950 switch and the authentication is completed successfully. Getting back to the 3750 stack the authentication failed and the laptop gains network access in the configured Auth-Failed Vlan. I have tried several configuration changes without success. I cannot understand why does this happen. I have made some debugs and I am sending them a long with a partial basic configuration of 3750 stack switch.
If anyone could check it and suggest anything it could be appreciated!!!
Thank you in advance!

Hi,
basically what happens is that the maximum EAP packet size for communication between client and RADIUS server is negotiated. Therefore, in your case the switch notifies NPS that the client is capable of handling packets up to 9000 bytes in size.
EAP messages, especially those containing the server certificate, are usually bigger than 1500 bytes and arrive at the switch in multiple fragments:
Mar 6 15:50:11.881: RADIUS(0000002C): Received from id 1645/41
Mar 6 15:50:11.881: RADIUS/DECODE: EAP-Message fragments, 253+253+253+253+253+253+253+253+20, total 2044 bytes
Having learned that 2044 bytes is acceptable for the client, the switch forwards the full message in one chunk, but since your client is likely to have set the interface MTU to 1500, the packet is oversized and never reaches its destination.
And yes, I think changing the System Jumbo MTU to 1500 bytes would lead to the same result. If my memory serves me right, a new setting takes effect only after a reboot, so I'd suggest giving it a go in your lab first.
Best regards,
Josef

Why does my 3850-24T-E running 3.6.2aE with IP Services licence not support GLBP?

Hi all,
Just upgraded two 3850-24T-E's to 3.6.2aE (cat3k_caa-universalk9.SPA.03.06.02a.E.152-2a.E2.bin) and I have triple checked that the IP Services licence was loaded from factory.
Even although the Cisco Feature Navigator says that 3.6.0E supports GLBP (See below) I can't execute any of the 'glbp' commands in interface configuration mode so obviously it's not supported:
ukxxxxAAxx01(config)#int vlan 100
ukxxxxAAxx01(config-if)#glbp ?
% Unrecognized command
ukxxxxAAxx01(config-if)#glbp
Can anyone explain what I'm missing? 3.6.2aE isn't available in the feature navigator - is it SO different from 3.6.0E?!
Thanks!
James.

You're going to have to give us more information to work with.
1. When did this start happening?
2. Have you added anything new to your system before this problems started?
3. When did you put Google Chrome Helper on there? XScan?
4. What other apps or functions are working strangly on there?

CBWFQ and Priority Q Scheduling with IOS

All,
I have a question in regards to scheduling in QoS.
I have below 2 priority queues (both pri quese go into one queue we beleive), and 3 CBWFQs.
The qestion is, how are these queus scheduled. I know that priority Qs will be emtied before moving onto the CBWFQ.
On the CBWFQ side, how are these scheduled, in a round-robin way? or is the amount of time they get serviced increased, the bigger the bandwidth statement is configured (Like custom-queuing and bigger queue configured in terms of bytes equates to more time being scheduled to empty the queue before moving onto the next queue)
policy-map carrier_cos
class carrier_EF
priority
police 1605000 8000 8000 conform-action transmit exceed-action drop
class carrier_AF4
priority
police 1530000 71500 71500 conform-action transmit exceed-action drop
class carrier_AF1
bandwidth 6120
class carrier_bulk
bandwidth 5480
class class-default
bandwidth 15265
Sounds to me like CBQFQ is a mixture of priority-queueing and custom-queuing combined.
Many kind regards for you help with this question.
Ken

Thx for that.
So, if I have a 1M/bit cct and have CBWFQ running.
CBWFQ 1 = Bandwdith 600
CBWFQ 2 = Bandwdith 200
CBWFQ 3 = Bandwdith 200 (class class-default)
assume interface is congested. How does the scheduler work?
Is it, within a time period, (let say 1second) it will spend 600ms servicing Q1, then move onto Q2 and spend 200ms on that queue before moving onto Q3 where it will spend a 200MS servicing that Queue and then go back to Q1?
Correct me if Im wrong, but is that the same as Custom Qeueing?
1 Second is a long time so what timer interval is used.
Remember is a 1M/bps circuit.
Kindest regards, and many thx.
Ken
