IP Multicast Layer 2 Aggregation

Please see the below diagram. I have a scenario where we currently receive three multicast sources on dedicated VLANs. As of today we do not do any pruning or snooping on this VLAN it is broadcast based and we would like to keep it that way as some receivers are mandated to not be IGMP-dependent.
HOWEVER, there is an exception. We have a network of receivers that need to have the granularity to request multicast group membership from multiple source VLANs and have non-interested traffic pruned from the receivers. This is a simple setup in a scenario where you have a single VLAN for the senders as I would just turn up a snooper/querier setup and let the local L3 switch handle the joins/leaves. Unfortunately though we have this need to allow multiple source VLANs to be candidates for sending to any downstream receiver. What I don't want to do is change the nature of the upstream multicast streams coming in to the switch. If that were the case then we could go to a routed multicast environment and not have to worry about VLAN segmentation issues.
What is the best practice/recommended config to allow a setup like this to work? I'm also concerned with the possibility of flooding multicast between VLAN A,B and C accidentally by combining the VLANs.

I need to be able to request streams from VLAN A, B, C on receivers on VLAN D. VLAN A, B, C are broadcast-based (no PIM or IGMP snooping) but I need the receivers on VLAN D to be pruned based on the stream that is being requested.

How to set Grand Total of a Measure when its aggregation rule is Max in Logical Layer

Hi
I have a Measure Column (Budget) and in Logical layer the aggregation rule is set as (Max) which looks like Max(Budget). But now it is included in the report and when my client is trying to see its grand total, it is giving the Max Budget figure of the report rather than giving the total sum(grand total).
Kindly share some ideas in achieving the grand total without disturbing the actual aggregation of the measure.

Thank You for your reply.
In my case i don't have a problem with aggregation for Budget Measure(max(Fact_XXKC_SHIP_TO_BUDGET_CAT_F.SALESREP_BUDGET_YTD)). This is the aggregation rule applied on the Salesrep Budget YTD.
Now i created a report with columns
Salesrepresntative(Dimension),, Sales Invoices(Measure1),, SALESREP_BUDGET_YTD(Measure 2).
In the above report the values are perfect, but when we used Grand total option at ROW level in table view, the grand total of Measure1 is cumulative of all the rows, but the Grand total of SALESREP_BUDGET_YTD (measure2) is the max of all the columns.
What i require is the Grand total of SALESREP_BUDGET_YTD (measure 2) should be cumulative of all the columns.
I have shared my SQL query, kindly verify it and share any idea.

Multicasting with an SGE2010P

Hi,
I have just purchased a SGE2010p switch. I am hoping to multicast with windows deployment services WDS
and also hoping someone might be able to give a basic explanation (configuration would be brilliant!) on the process.
On the switch webpage, we ticked the box for IGMP snooping. WDS configured with multicasting and that part of
it works. Getting transfer rates of 16,000KBps (according to WDS console). Would have thought gigabyte should be
better than that, but still better than the 250KBps without IGMP snooping.
The problem is that all traffic is still being sent to all other ports on the switch. There is only the switch
and no routers involved. Some documents indicate IGMP querier is required, but there seems no option for that that
I can find. I believe we later enabled autolearn (but not certain - dont have access to the switch at the moment)
and then WDS broke <again>.
So I am hoping someone can please educate me!
What needs to be done to prevent the switch from forwarding data to all ports
Is AutoLearn the same as an IGMP querier?
What is bridge multicast forwarding? Sounds like passing multicasts across routers?.
Do we need to create a multicast group on the switch? I would think no, that WDS does all that.
Does this switch support MLD snooping?
Any help appreciated
thank you!

That's not going to work; manually defining groups means static multicasting (ie not dynamic nor scalable). That sort of defeats the purpose of IGMP snooping.
The problem is Microsoft's default multicast range is incompatible with IGMP and switches.
When a multicast layer 3 address is mapped to layer 2 (for the switch multicast layer 2 address), only the last 23 bits of the IPv4 address come across. The other bits are lost as we need specify the ethernet OUID owned by iana. (01-00-5e).
So the default range by microsoft 239.0.0.1-239.0.0.255 maps out at the ethernet layer: 01-00-5e-00-00-01 to 01-00-5e-00-00-ff
The problem is, the 224.x.x.x mulicast control messages also map out like that, e.g. 224.0.0.1 maps to 01-00-5e-00-00-01.
So 224.0.0.1 and 239.0.0.1 map to the same ethernet (layer 2) mac address. Therefore the switch has no alternative but to broadcast as 224.0.0.1 = all nodes.
So try changing the default WDS address to something that wont get confused by the switch, e.g. 239.67.54.3 to 239.67.54.255.
Have tested this in a lab only but should fix the problem.

Oh, bridge multicast forwarding is for when the traffic needs to be forwarded (ie to another switch or router). Filtering is only to be touched to block all multicast traffic - perhaps for permanent groups that need to be manually configured. You dont need to touch that.

MultiCasting with applets ??

Hi
I would like to ask about how can i avoid the problem of using the multicast socket with the applet as i want to build an applet and i knew that multicasting is not applicable with applets
but also i wanna use multicast socket for the multicasting of data stream in conferencing project
so any suggestions related to this problem is appreciated

• You cannot configure Spanning Tree Protocol parameters, such as bridge priority and hello timers.
Ethernet Switching Mode
The Ethernet switching mode determines the way that the fabric interconnect behaves as a switching device between the servers and the network. The fabric interconnect operates in either of the following Ethernet switching modes:
• Switch mode
• End-Host Mode
Switch Mode
Switch mode is the traditional Ethernet switching mode. Use switch mode when the fabric interconnect is directly connected to a router, or when Layer 3 aggregation or a VLAN in a box is used upstream (Figure 32). Switch mode has the following attributes:
• The fabric interconnects run Spanning Tree Protocol with connected external switches to avoid forwarding loops; broadcast and multicast packets are handled in the traditional way.
• The fabric interconnects run Per-VLAN Spanning Tree Plus (PVST+), which cannot be changed to another Spanning Tree Protocol such as Multiple Spanning Tree (MST).
• You cannot configure Spanning Tree Protocol parameters, such as bridge priority and hello timers.
• MAC address learning and aging are enabled on both the server links and the uplinks, so that the switch operates like a typical Layer 2 switch.
• Some uplinks connected to external switches may be blocked by spanning-tree rules.
Also remember that you are limited to the options presented to you via the CLI and GUI. They should have the same capabilities. If you do not see an option for configuring spantree priortiy, changing the value is not supported.

Small DC Switch Design

Hello,
I'm working on options for a small DC switch design. This DC has 5
virtual hosts with 10-20 guest vm's each. Each server has two quad
port gig nics with 6 of the 8 gig ports connected (3 for iSCSI and 3
for data or management. It also has two 3 node sans each with 2 gig
ports per node, a host of other small servers including voice servers,
management servers, asa firewall, and a few routers. Total of 50-60
ports as of right now.
Connected to the DC is 7 other buildings each with there own 1 gig
fiber connection serving about 3000 devices in total including
desktops, laptops, ip phones, wireless ap's, building automation,
alarm panels, etc....
Right now in each of the 7 buildings has a 3560G as an aggregation
switch connected back to the DC. The DC also has a few 3560G's and
3750G's for the sans and servers. The system seems to work ok for the
most part aside from micro bursts overwhelming the buffers on these
switches and the etherchannel trunks between them dropping a minor
amount of packets. QOS is configured for the voice network and there
are little to no complaints.
What I would like to know (costs being the biggest factor) is what
would be a better switch design for the current and future traffic in
this network. Some options I was thinking about are as follows:
I would needs at least 96 ports.
So option A is to go with a 4506-E bundle with 2 48 port line cards,
sup 6l-e and a WS-X4712-SFP+E or something of the sorts.   And then
upgrade to the enterprise services license and do all of the routing
and switching for the DC on this one switch. Means little redundancy
and no failover.
Option B was to go with the same 4506-E bundle, without the extra
license and without the SFP line card and put in some sort of layer
three aggregation switch, possibly an me3600x.
Option C Is to go with the 4503-E, the SFP line card and the IP
Enterprise services license. And two top of rack switches, either
2360's or 4948's.
I would like to do some PBR on the aggregation switch, but I am unsure if the me3600x is capable of doing that.
I have no experience in this matter so any other thoughts or
suggestions would be appreciated.
Thanks,
Dan.

If cost is the biggest factor, and the only notable issue now is occasional packet drops due to insufficient buffers, perhaps some buffer tuning would be something to consider.
A really important question to answer is how important redundancy. At lower port densities (3 to 4 stack members), the switch stack is less expensive than a chassis that supports redundancy. At very low port densities (2 to 3 stack members) the stack might be less expensive than even a non-redundant chassis.
BTW, the 3750-E/X offers much more performance than the original 3750 series. If offers wire-speed PPS and fabric per switch, twice the ring bandwidth and uses the ring, for unicast, much "smarter".
Perhaps a dual WS-C3750X-12S or WS-C3750X-24S for your core with dual MEC fiber etherchannl links to your aggregation switches? In the DC itself, you might also use 2960s to provide DC edge ports. For growth, a dual 3750-X stack would support four 10 gig ports which could be used with 10 gig servers or 10 gig SAN or as a 10gig link to other DC switches, such as the 2960S (which support their own stacking technology).

Level based measure issue

i am a starter in obiee.I want to develop a following report
categoryid, revenue sum of revenue by categoryid
in rpd, there is a join between customer to salesfact on category id.
i made a duplicate of revenue(sum of revenue) in business model layer,put aggregation as sum.then set level as category id
still it displaying same data as revenue.but i want sum of revenue group by categoryid
any solution

BI Statistics - query level of detail

Hi,
Is it possible for us to specify the level of detail for the queries we create? If its possible please tell me how to do it?
Regards,
Suraj

Hi Suraj,
   Yes its possible to specify the level of details for query objects. Here is some info...
<b>Statistics Detail Level for the Query Object Type</b>
For queries, you also have the option of selecting a detail level for the statistics data. You can choose from the following:
●      0 Aggregated Data: The system writes only one OLAP event (event 99999) for the query. This contains the cumulative times within the OLAP processing of the query. The system does not record data from the aggregation layer of the analytic engine or aggregation information.
●      1 Only Front End/Calculation Layer Data: The system records all OLAP events, but not separate data from the aggregation layer of the analytic engine. The system writes only the general data manager event 9000 in the OLAP context as well as the aggregation information.
●      2 All: The system records all data from the area for the front end and calculation layer as well as data from the area for the aggregation layer and aggregation information.
●      9 No Data: The system does not record any data from the front end and calculation layer or from the aggregated event 99999. However, it does record data for the BEx Web templates and workbooks, depending on the setting.
When you select the detail level, keep in mind that a very large amount of data is recorded when the system records data manager times.
Hope this helps...

Sum Aggregation Error in Physical & BMM Layer in OBIEE 11g with Essbase 11

Hi everyone,
I'm using OBIEE 11g with Essbase 11 as the data source. I'm using Sample Basic database from the Essbase as my data source. If I'm using the hierarchy for the measures (so I don't flatten the measures), and when I changed the aggregation in both physical and BMM layer from Aggregate_External to Sum, I can't create a report at all from the Answers.
Does anyone encounter the same thing? Any ideas/solution about this? Please help.
Thanks a lot!

Hi Deepak,
When I picked the "Basic - measure" alone, I got this error.
Error Codes: OPR4ONWY:U9IM8TAC:OI2DL65P

When I picked the "Gen1,Measures" alone from the measure dimension, I got this error:

But when I queried the dimensions one by one (only single dimension each), no error was shown.
This only happens if I use Sum in the physical and BMM layer. If I use External_Aggregation, these errors do not happen. And if I flatten the measures, these errors also do not happen.

Layer 3 network and netboot/multicasting - will/can it work across subnets?

Hi, have been running netboot across a few subnets using multiple nics and vlans that worked fine.
We're to move to layer 3 so the vlans are going.
So my problem is getting it to run across the subnets. Is there something we need to do to the network to allow me to it see the netboot images and can I run things as before, or as I suspect do I need to move to multicasting?
Apologies if my question is a bit vague. Not 100% sure what the network change will do to the netboot system and how to adapt to it. thanks, Patrick

Multicast blocking in layer 2 switch

Hello there,
I need your help, this is the problem that I have.
We have a 3750X with 7 ports assigned to a different multicast IP address (connected to the encoders), these are the ports with the multicast ip address and the rate that the encoder is sending:
Pto 2 - 230.1.1.1:5001 - 3.5 Mbps
Pto 3 - 230.1.1.2:5002 - 3.5 Mbps
Pto 13 - 230.1.1.22:5022 - 15 Mbps
Pto 13 - 230.1.1.23:5023 - 15 Mbps
Pto 13 - 230.1.1.24:5004 - 15 Mbps
Pto 13 - 230.1.1.25:5025 - 15 Mbps
Pto 13 - 230.1.1.26:5026 - 5.0 Mbps
The last port (48) is connected to a different device and this box is receiving the multicast ip addresses. My problem is that in every single port on the switch is receiving all the multicast traffic so the switch is having high cpu, I have the outputs from the console monitor (application that sees the odd behavior).
As far as I know this is expected since this is layer 2 device but I'm not sure. Please help so I can configure what I need to stop the high cpu and the traffic to be sent over the rest of the ports (including those ports).
Kindly regards

Hi ,
You can block layer 2 Multicast traffic with following commands
Step 3
switchport block multicast
Block unknown multicast forwarding out of the port.
Note Only pure Layer 2 multicast traffic is blocked. Multicast packets that contain IPv4 or IPv6 information in the header are not blocked.

Blocking Multicast on Layer 2 switch

Cisco 2960, layer 2.
trying to block inbound multicast from a single switchport. My CUCM to be exact.
IGMP will not do what I need as I have phones trying to listen to Multicast MOH from the server, and Im trying to block it. Phones and server are on the same subnet. I do not want the MC packets to hit the phones as they need to listen to something else on the same IP
ACL on the port didnt work, neither did switch block multi as I think it doesn't block packets with a correct source mac.
Storm-control multi level 0 didnt work, neither does storm-control broad level 0
Any other options? Or are one of these options actually working and I just dont know it (my multicast isn't setup right lets say). I see my multicast counters on the port go up when I turn on multicast from the server so I know its being sent.

Create entry for characteristic which is not in aggregation layer

Dear all,
I have an realtime cube with an aggregation layer on top for a planning application. For some reason I can not include one characterisctic in the aggregation layer.
Although I need a value for this characteristic, e.g. after each saving within the planning application.
Is there a way to create entries (constant) for specific characteristic which are not part in the aggregation layer.
We are running NW 7.1.
Any help would be great.
Best regards,
Stefan from Munich/Germany

Hi,
As tilak has mentioned above, you can use characteristic relationships to derive a characteristic data based on another charactereistic value.
The following are thr things are the things to be kept in mind whn using characteristic relationships,
1. Load the master data properly for the required characteristics if you are using relationship of type, either attribute or hierarchy.
2. If you want to derive rthe data based on your own requirements, use relationship of type DSO or Exit.
3. Make sure that the particular characteristic relationship after creation, inorder to use it in your planning application.
For more details, you can refer to the link, [Re: IP: Characteristic derivation during Transfer values|Re: IP: Characteristic derivation during Transfer values]

Vlan Select & Layer 2 Multicast optimization

I am going to implement this vlan select feature in my campus network. We are running on 7.3 & planning to move into 7.4 WLC code as well. I use below reference document for this task.
WLC 7.2 VLAN Select and Multicast Optimization Features Deployment Guide
I am bit confuse about layer 2 multicast optimization. Document says we can enable/disable by using below CLI commands. "
config network multicast l2mcast <enable|disable > <interface>"
I have 4 interfaces called student-wireless-1 to 4 (vlan 1161-1164) map into single interface group. For layer 3 multicast I will make vlan 1161 as the multicast interface with "multicast vlan feature" enabled. For layer 2 what should I do ? Is layer 2 multicast enable on all these interfaces by default ? If so should I disable l2 multicast on 3 of these interfaces like below ? Would there be any issue of disabling this layer 2 multicast on those interfaces ?
config network multicast l2mcast disable student-wireless-2
config network multicast l2mcast disable student-wireless-3
config network multicast l2mcast disable student-wireless-4
If it is not enabled by default, shoud I go ahead enable it on one interface like below ?
config network multicast l2mcast enable student-wireless-1
If someone can explain this that would be highly appreciated.

Thanks for the help but I found some further information. Some switches (2955, 2960, 3560 or 3750) can act as a "multicast querier", taking place of a multicast router without actually needing to support multicast routing. This means you dont actually need IP Services IOS or a layer 3 switch.

Creating an Aggregation Layer

I am trying to create an aggregation layer which is to built off a multi provider which has a real time info cube. When I try and create the aggregation layer I get the message:
Aggregation Level <level name>: Infoprovider <Info provider name> cannot be used for definition
Why am I getting this message and how can I resolve it? Thanks

At least one key figure and one characteristic have to be included in the aggregation level.
●     The key figures used have to have the database aggregations SUM, MIN or MAX. With MIN or MAX, key figure values can only be displayed. They cannot be changed using manual planning or planning functions.
●     For key figures of type date or time, only the data type u2018DECu2019 is supported.
●     Referencing key figures (and thus also non-cumulative key figures or elimination of internal business volume) are not supported in aggregation layers.
●     If a characteristic is compounded and used in an aggregation level, the aggregation level must also contain all compounding "parent" characteristics.
●     If a key figure is used in an aggregation level and does not have a fixed unit of measure or currency, the aggregation level must contain the associated characteristic for the unit.
●     If a key figure with exception aggregation is used in an aggregation level, the aggregation level must also contain the characteristic for exception aggregation if it occurs in the underlying InfoProvider
●     The aggregation level inherits a navigation attribute from the underlying InfoProvider if it includes the basic characteristic of the navigation attribute. Note that the navigation attribute for an aggregation level is not visible in the Planning Modeler. It is only visible in the Query Designer.
●     An aggregation level cannot be created on MultiProviders if a characteristic of an InfoProvider contained in the MultiProvider supplies two different characteristics in the MultiProvider.
●     If a characteristic on the InfoProvider that serves as the basis for an aggregation level is constant, this characteristic has to be included in the aggregation level.
Hope this helps.
