ME 3400 in Enterprise LAN - ?

Hello,
There is a quite interesting in value-for-money perspective model ME 3400
(see http://www.cisco.com/en/US/products/ps6580/products_data_sheet0900aecd8034fef3.html)
Cisco ME 3400G-12CS AC with 12 dual-purpose (10/100/1000 and Small Form-Factor Pluggable [SFP]) ports, four SFP uplinks, and two fixed redundant AC power supplies (part number ME-3400G-12CS-A)
which costs less than 3750G with 12 SFP slots and no redundant Power supply nor copper GigEth ports.
I am designing LAN for an enterprise customer with around 10 aggregation switches. In the core will be two Catalyst 6513.
As aggregation - either some 3750G, 3560G or these ME3400 - which are a lot more flexible.
I've checked, and such enterprise LAN Network Mgmt software as CiscoWorks LMS 3.0 supports them.
Where is the catch - it seems that Cisco does not recommend ME3400 for Enterprise LAN - or what? We have not had any experiense with ME3400. Please Help.

Hi,
The catch is that it doesn't run standard "enterprise lan" software - it runs software customised for the service provider environment. It might be possible to make it work in the enterprise but I sure wouldn't recommend it.
The ME switches have a different interface configuration - all ports must be UNI or NNI and different protocols are not necessarily supported on both port types. Make sure you completely understand the difference! Also, there are two types of UNI VLAN among other differences and a lot of unsupported "normal" IOS commands.

Filtering/Dropping IPv6 on IPv4-only Devices?

Hi All -
Got an interesting requirement that (for something seemingly simple) has been remarkably challenging to locate a solution for...
Having a problem with random IPv6 traffic showing up on the enterprise LAN from time to time and freaking out certain network-connected devices that don't know how to process it (CPU 100%, etc.). So I'm looking for a way to filter/drop that IPv6 traffic at the network edge. I can certainly set the core 6500's not route (or even ignore) IPv6, but that still doesn't stop it from running around WITHIN a VLAN.
Is there a way that a IPv4-only device can identify IPv6 traffic (by a protocol type code or something along that line) so that it can be filtered/dropped before it even makes it onto the backbone?
Thanks in advance!
Mike

Mike-
Good question! The first thing I thought of was VACL's, but VACLs w/IPv6 are not supported on the 6000 series switch.
http://www.cisco.com/en/US/tech/tk389/tk814/technologies_configuration_example09186a00808122ac.shtml#vacl
Are the 6500's your access layer? Are they your L3 gateway? Is it possible for you to find the device(s) running IPv6 and correct them?

WRR QoS unused traffic classes

We are planning QoS for the enterprise LAN and MPLS core. At present, there are 5 traffic classes identified and no VoIP traffic. We could allocate resources and bandwidth for 5 queues and deploy such configs. But I guess it's worth defining all 8 classes and allocate queue limits and bandwidth to them. Later it will be easier to mark the new traffic and classify it into the unused queues without modifying the wrr config.
67xx 1p7q8t line card
Q3 and Q8(PQ) will not be used. 5+15% is allocated to them.
priority-queue queue-limit 15
wrr-queue queue-limit 30 15 5 10 15 5 5
wrr-queue bandwidth percent 30 15 5 10 15 5 5
I'm not sure if the allocated bandwidth and queue limit for the unused queues will affect the existing traffic and limit the aggregated traffic quantity. Will the 5 classes be able to fill the bandwidth until there is no congestion? What happens in case of congestion? Can the traffic excess 80% or not? (For simplicity, 100% is regarded as a fraction of link capacity defined by max-reserved-bandwidth)

Generally, unless you're shaping or policing, bandwidth sharing commands provide a minimum bandwidth guarantee, and unused bandwidth can be used by other queues. Also when working with more than one queue, relative ratios are usually preserved. So, for instance, if q1 was configured for 25%, q2 for 25% and q3 for 50%, if q2 had no traffic, and q1 and q3 wanted all they could have, they would split the bandwidth 1:2 or 1/3 to 2/3.

New WLAN(s)

Last year we had a glut of resources. I purchased a 5508 WLC with a (50) AP license, (12) 1042 APs, and (12) 3500 APs. We already have 6 APs in the field run by a 2106.
What I would like to do is supply wireless access to all of the laptops and iphones that are corporate, and also provide guest access. At the same time, I would like to make the lives of the outside workers who maintain a VPN connection all day in the home office a bit easier with Office Extend.
So - I'm at a place where I don't know where to begin. That is an excellent place to start I think
I would like to deploy in stages - replace the current infrastructure, provide guest access, and have the remote users connected in stages. It's all about how to get started at this point.
Thanks,
Ed

Hey Ed,
I would recommend you check out some of the Smart Business Architecture (SBA) documentation at http://www.cisco.com/go/sba/. It is straightforward documentation with lots of screenshots and easy to follow instructions to get you up and running with a wide range of Cisco products.
Based on what you have asked for (LAN WiFi, Guest Access, and Office Extend) I would check out the following documents:
Enterprise LAN Deployment Guide (Wireless LAN section)
Teleworking Deployment Guide (Cisco OfficeExtend section)
Want some authentication then check out this guide:
LAN and WLAN 802.1X Deployment Guide
And since you bought some pretty sweet 3500s I would recomend that you check out this guide:
Wireless CleanAir Deployment Guide
There are some other guide with more Advanced Guest Wireless as well. If you are a smaller organization then checkout the Midsize docs for doing coresident LAN and Guest on the same controller.
Also we doing a major overhaul on our documents to be release in August so be aware that the format will change a little bit but the archtectire (as always with SBA) will stay the same.
Please let me know if you have any questions or comments about SBA!

Annoying behaviour on WPA Enterprise wireless LAN

I have a PB 1.67 running OS X 10.3.9 (all patches installed)
When I connect it to our WPA Enterprise wireless LAN, I experience the following annoying behaviour.
Authentication may be slow (sometimes 10 to 15 minutes), but connection usually succeeds.
Then while I am actively web browsing or retrieving email, things are ok. However if I have to leave the computer for about 3 or more minutes, it seems to decide that it should no longer be on the network and I have to disconnect and then reconnect.
No send/rec errors show up in the info tab of network utility. IP address is there, status is active and the link is reported as 54Mb. It appears that my machine is not interested in participating on the network until it has been reconnected.
Does anybody have any ideas on how to track down what might be happening?
Thanks in advance.

A follow up:
I have observed that when I am this non-working state, my 802.1x authentication status shows idle.
Is there a way that I can trace what is happening at the 802.1x layer?

DCNM for LAN Enterprise License for one Nexus 7000 Chassis

if i have just DCNM-N7K-K9 (DCNM for LAN Enterprise License for one Nexus 7000 Chassis) installed on a server, i can manage all nexus switches like 5k and 2k??

You can manage 2K & 5K devices but a $0 cost license is required. A purchase order for DCNM-NXACC-100-K9 should do the trick.
Thanks.

Oracle 10G Non-Network install - OEM will not start when on the LAN.

Greetings,
Got through a non-networked 10G Enterprise installation OK; I chose to create the orcl schema, connected to it through various utilities, added new tablespace, and all was well. I also checked my Host Name by pinging it in DOS, it showed me the IP address of the MS loopback adapter which is what I was expecting.
Once I connected the same machine to the LAN (and internet) and re-booted, for some reason the Host Name was now assigned the dynamic IP address of the LAN and not LAN2 (which is the loopback adapter that is assigned a static local IP address). It did this even though I had already added an entry in the /etc/hosts file that explicitly assigns a static IP address to the Host Name (as recommended in the Oracle 10G pre-installation instructions). I also could not get the OEM to launch a webpage, run and connect to the orcl database after the re-boot; I am wondering if this is related to the IP address assigned to Host Name changing; maybe the Oracle agent can no longer resolve the URL for some reason?
In the end I find that the only way to insure I can have a working Oracle environment and be on an active network at the same time, is to bring up the Oracle environment on a standalone system first, and once Oracle is running connect the system to the network. Is there no way to automate this process?
The format of the hosts file entry recommended by the Oracle 10G pre-installation instructions is as follows:
===========================================================
IP_address hostname.domainname hostname
where:
IP_address is the non-routable IP address you entered for the loopback adapter.
hostname is the name of the computer.
domainname is the name of the domain.
For example:
10.10.10.10 mycomputer.mydomain.com mycomputer
==========================================================
In my case since I am not part of a Windows domain (but am part of a Windows Workgroup), I added an entry in the /etc/host file that looks like the following:
# Copyright (c) 1993-1999 Microsoft Corp.
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
# For example:
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
127.0.0.1 localhost
192.168.110.250 IBM-6AB1330E158
==> Note that I did not add the domain name to the entry I created since I am not part of a domain, I also used the format I found in the etc/hosts file which is:
IP_address hostname.domainname
- not -
IP_address hostname.domainname hostname
Which is the format recommended in the Oracle 10G pre-installation instructions; this does leave me wondering which format is correct...
Thanks in Advance for any help,
ADG13

I have not. I am hoping someone (maybe even from Oracle support) will step up and officially tell us we are either right or wrong in the way we are approaching this. From the research I have done on the internet it sounds like this should work, you should be able to have Oracle starting and running fine whether you boot connected to the LAN or not, assuming you have created the MS loopback adapter, assigned it a static IP, and changed the hostname entry in etc/hosts file as part of the 10G WinXP recommended pre-installation instructions.
And yet I find I have to start Oracle when I am not connected to the LAN or the services will not start correctly. If this is a "feature" then hopefully someone will tell us and maybe give us a workaround or give us an idea if this will be addressed in a future release. Having said that and in fairness to the Oracle product; being a developer I have other products installed on my machine that have special networking setup needs also, and in my case this could be exasperating or even possibly causing this Oracle problem I am having. To be specific I have software for 2 different VPNs installed so I can tunnel into 2 private networks. One of these VPNs require me to make use of a DNS Suffix (as shown below) which might be contributing to my problems, not sure. I also have VMWare installed which uses it own network adapters when it is running, so you can see how things could get a little hairy... at any rate, there is my 2 cents worth (or is that 5 cents? : )

Dual Monitor video cards for HP Pro 3400

I am looking to add a 2nd monitor to my HP Pro 3400 MT and want to make sure I get a video card that will not have any compatibility issues. I'm not doing any gaming so I don't think I need anything super fancy and I would prefer not to have to upgrade the power supply.
So my questions are:
Is the HP Pro 3400 MT compatible witha PCI Express 3.0 card? 2.1 ?
How much power draw from the video card would require me to upgrade the power supply (my PC is stock, no added peripherals). Is there a way for me to determine how much is being currently (no pun intended) drawn?
Are there any drawbacks to usnig the built-in video card for 1 monitor and a new, single-ouput card for the other (vs a dual-output card) ?
Anything else I need to consider when deciding on a new video card?
Thanks.

Exchange 2013 SP1 on Windows Server 2008 R2 Enterprise - BSOD after DAG creation

Hi,
We are running Exchange 2007 SP3 RU13 on Windows 2003 R2 with SP2 in a 2003 native AD environment and recently decided to upgrade to Exchange 2013. We installed a pair of new DELL R420 servers running Windows 2008 R2 Enterprise then threw Exchange 2013 SP1
onto them. This all went fine and the servers are running stable.
We connected the second NIC of each server to the other via a separate switch, the second NIC has Client for MS Networks and File/Printer Sharing disabled plus a totally separate subnet with no DNS or GW address assigned. DAG setup was run and completed
OK. I created the DAG network in Exchange and enabled replication, I also left replication enabled across the production LAN. Finally, I went into the advanced network settings and made sure the replication network was below the production network in the binding
order.
After an hour or two the BSOD's started.. both servers would crash within a few minutes of each other and reboot with a Kernel Panic. I have attached the contents of the dump file below. This seems to happen every few hours and it always seems to be the
server hosting the passive DB copies crashes first, followed by the server hosting the active copies. Note that if we disable the replication NIC on both servers they do not crash.
I got the impression from somewhere that perhaps the servers had mixed up the binding order and were trying to use the replication network as primary, losing access to AD and rebooting (which I have read is the behaviour for Exchange now). It appears the
Exchange Health service has killed WININIT which causes the crash.
Thanks!!!

Hi Darrkon,
I suggest checking the status of the HealthMailbox on each of servers.
Also try to re-create the mailbox. You can safely delete and recreate health mailboxes.
Be aware that any local Managed Availability probes that are using the these mailboxes will fail until the Microsoft Exchange Health Manager is restarted. Once that service is restarted, it will recreate any mailboxes that it needs.
More details in the following similar thread, just for your reference:

WRT400N - frequent disconnects on Windows 7 Enterprise

I work from home for a software company, so I'm constantly online transferring data and talking to customers via Skype & a Cisco IP Phone. I've got my work laptop PC (running Win7 Enterprise) connected to the WRT400N using a LAN cable (wireless is for a MacBook Pro my wife uses). The WRT400N is updated to the latest firmware.
The problem I'm having is that I'm getting disconnected throughout the day, and nothing short of power cycling the wireless router is fixing the problem. I've tried disabling and re-enabling the LAN adapter, ipconfig /release and /renew, and rebooting the laptop. It seems that each time, I am forced to power cycle the router to restore connectivity.
I used to use the wireless adapter on the laptop, but due to frequent disconnects I moved the router to sit directly next to my laptop and just hooked up the LAN cable. I discovered that my Comcast modem was actually dropping connectivity so I had them swap it out for an updated model and since then I can see that it's staying connected (and yes, I'll admit I'm doing the n00b test of watching the LEDs to see if they're blinking off whenever I lose connectivity now). As I type this I have actually switched back to using the wireless adapter which hasn't disconnected in the past 6 hours (a record).
Long-winded so I apologize. I really would like to resolve this issue somehow but I'm not a network expert by any means and I've exhausted my limited ability to troubleshoot.

Try to follow the below mentioned settings and then check.
Open an Internet Explorer browser page on your wired computer(desktop).In the address bar type - 192.168.1.1 and press Enter. Leave Username blank & in Password use admin in lower case.
Click on the Wireless tab
Here select manual configuration...Wireless Network mode should be mixed.
Provide a unique name in the Wireless Network Name (SSID) box in order to differentiate your network from your neighbors network.
Set the Radio Band to Standard-20MHz and change the Standard channel to 11-2.462GHz...Wireless SSID broadcast should be Enabled and then click on Save Settings...
Please make a note of Wireless Network Name (SSID) as this is the Network Identifier...
Click on the Sub tab under Wireless > Wireless Security...
Change the Wireless security mode to WPA2, For Encryption, select TKIP...For Passphrase input your desired WPA2 Key. For example , MySecretKey , This will serve as your network key whenever you connect to your wireless network. Do NOT give this key to anyone and remember the key.
NOTE : Passphrase should be equal to or more that 8 characters...
Click on Advanced Wireless Settings
Change the Beacon Interval to 75,Change the Fragmentation Threshold to 2304,Change the RTS Threshold to 2304 and Click on Save Settings.

State of the enterprise network & wireless technology

In your opinion, what do you think is the single most gating factor for an enterprise to be able to provide wireless access to corporate resources on a LAN?
and what does an enterprise need to do today to get their network ready for wireless?

In our environment, infrastructure was the biggest factor. It is very difficult and expensive to wire (and re-wire) our facility so putting in access points throughout and wireless nics eliminates the problem. It also very convenient for our users with notebooks. There are other factors as well but thats the main reason.

Hi boadiceaa,
Is the machine in a domain environment ?How did you configure the screensaver ?
Usually we can configure it here .
Right click the blank desktop ,choose personalize ,screensaver.
There is a registry key we can configure the timeout of the screensaver .
HKCU\Control Panel\Desktop\ScreenSaveTimeout
If it is a domain environment ,please check whether the screensaver group policy has been configured.
We can run "rsop " to have a check .
We also can try to configure it from the group policy

If the issue persists, we can try to login with another account and configure it to have a check .This will help us to narrow down whether this issue is caused by the specific account .
Best regards
im not exactly sure what you mean by domain but its for my home network, just simple SOHO. ive tried using another user account to change it but it doesnt matter what it only goes to 15 mins max time.
youd suggest i look into the registry for starters or?
thanks again for the reply

Publication of the big-sized Enterprise projects from Project Professional 2013 to Project Server 2013 takes about 60+ minutes.

Dear Sirs,
I need your support over the following MS EPM 2013 issue:
Publication of the big-sized Enterprise projects from Project Professional 2013 to Project Server 2013 takes about 30+ minutes. We
need to reduce this total publication time down to acceptable working values 10+- minutes.
Environment information:
Single App Server (Virtual): 16 Gb RAM, x64 4xCPU, HDD > 50 GB free disk space, OS Windows Server 2012 Standard Edition x64 Service
Pack 1, MS SharePoint Server 2013 and MS Project Server 2013 with CU December 2013 (KB 2850024) applied.
Single RDBMS MS SQL Server (Virtual): 8 Gb RAM, x64 4xCPU, HDD > 200 GB free space, OS Windows Server 2012 Standard Edition x64 Service
Pack 1, MS SQL Server 2012 x64 SP 1 Enterprise Edition.
We have 1Gbit LAN between APP, DB server and 1Gbit LAN between APP and Proj Prof Client.
Yes, we are on the way of migrating to the Prod environment
with 3-tiered architecture (with SP1 slipstream and CU December 2014 applied), but this issue also
presents there.
Project’s file information:
Tasks in the file: [~4900], resources in the file [~396] enterprise task’s custom fields used in the file [~23].
Project save procedure for this new project would last about 7 minutes. Project publication would last about 47 minutes. We noticed that
tasks synchronization process took about 1 second for each ~2,5 tasks, to add them to the sharepoint tasks list. So for all 5148 tasks it took about 5148/3/60 = 34 minutes. Other 13 min was used for reporting database publication and other tasks relevant
for new sharepoint site creation.
Case 1: Issue description:
During the Enterprise project’s file save and publication we have the following sharepoint 2013 log messages:
07.31.2014 12:43:17.22 Microsoft.Office.Project.Server (0x0358) 0x3D5C SharePoint Foundation Monitoring b4ly High Leaving Monitored Scope
(Persisting list changes). performing time =376.068676326181 22dca99c-4696-70f1-e9e2-06851d0bcffd
07.31.2014 12:43:17.69 Microsoft.Office.Project.Server (0x0358) 0x3D5C SharePoint Foundation Monitoring b4ly High Leaving Monitored Scope
(Persisting list changes). performing time =361.652807828928 22dca99c-4696-70f1-e9e2-06851d0bcffd
It shows that sharepoint spend at least ~350 milliseconds (or 0,35 sec*4900 tasks = 1715 sec, or 28,5 min) for each task update during
project publication. And we also have another log file that shows that about 0,7 sec (or 0,7 sec*4900 tasks = 3430 sec, or 57 min) sharepoint spend for save each task in project file to project server. So total save and publication time more then 60+ minutes
for that project file. The same result we have even if user didn’t do any changes at the project file.
We use only enterprise projects (dbo.MSP_EpmProject_UserView.projectvisibilitymode = «False»), and do not use sharepoint tasks lists,
but the synchronization between MSP Plan and SharePoint tasks list works at any case.
Case 2: Issue description:
- For the second test we created a new project with new sharepoint project’s site on basis of our «issue» project, with total amount
of tasks in it of 5148 (yes, we increased the tasks list default limit at the sharepoint site up to 6000 items in it – standard limits for sharepoint view list – 5000 items).
- Project save procedure for this new project would last about 7 minutes. Project publication would last about 47 minutes. We noticed
that tasks synchronization process took about 1 second for each ~2,5 tasks, to add them to the sharepoint tasks list. So for all 5148 tasks it took about 5148/3/60 = 34 minutes. Other 13 min was used for reporting database publication and other tasks
relevant for new sharepoint site creation.
-Then we deleted the
tasks list for that new test project from the sharepoint site and republish the project plan one more time. This time project save procedure took about 7 minutes, project publication about 2 minutes and 3 minutes for other relevant queue jobs. So total time
is 12 minutes.
As a conclusion: yes, we have determined
the exact problem - during synchronization process (from Project Server to SharePoint) it perform copying all tasks and related data from Project to SharePoint in spite of fact that you changed only ONE task or ALL of them. At any case, synchronization will
copy ALL of them from Project Server to SharePOint task’s list.
Our workaround is to disable the task’s synchronization for such big-sized project plans:
– to delete the SharePoint «tasks» list at the SharePoint site tied with project plan.
- or deattach the SharePoint site from the project plan.
Thank you for reading this topic, please if you also forced with such issue provide us any known workaround or maybe any official response
\ feedback from MS about it.
Thank you in advance,
Best Regards, Andrey

Regarding my topic, I also said that every time when sync works it updates All items from project’s plan at Project Server to corresponded task’s list at SharePOint server. Inspire of the fact that you changed only One task or group /
all of them at your project’s plan.
And it seems to me and my colleagues that it’s probably (maybe) a “bug” at the product. Here is what we have if looked a little bit closer to the code:
Share Point determines what task to sync from Project’s plan to sharepoint list. To do that sharepoint needs to know was that task changed or not, based on the following fileds (check SQL stored procedure “[MSP_READ_TASKS_FOR_SYNCRONIZATION]”):
TASK_UID    TASK_NAME    TASK_START_DATE    TASK_FINISH_DATE    TASK_PCT_COMP    TASK_PARENT_UID    TASK_OUTLINE_NUM
WSS_LISTITEM_UID   TASK_ID    TASK_IS_ACTIVE
We noticed that at any case synchronization performs for all tasks, EXCEPT the ROOT one. Then we looked at the comparison of TASK_PARENT_UID field. So sharepoint compares TASK_PARENT_UID with ParentID (this is internal name for lookup
field “Tasks” at the Sharepoint, and it stores their values at the format "ID;#Title").
And comparison performs like following:
SharePoint looks for Task at the Tasks’s list corresponded to Project’s plan with ID represented at the TASK_PARENT_UID field. Then it takes SharePoint ListItem ID (“int” type) and store it to the “num” parameter;
num = this.GetCachedListItemByUniqueId(listItem.ParentList, nullable.Value).ID;
2.Then it compares “num” with task’s “ParentID” at SharePOint as follow with operator “!=”:
((SPItem) listItem)["ParentID"] != (System.ValueType) num
3. If comparison was success (true) – then it tell us that values (at the Project’s plan for tasks) was changed, then it need to be synchronized. Corresponded Method setup “true” flag, and then returns it.
The “bug” is that this expression at the Step 2 will always return “true”, because in fact it compares “string” (see above – that this is lookup field at SharePoint side)
with “number”. For example if the parant task ID is “55”, then we get:
"55;#Task 1" != 55
And by the rules of .Net the “string” will never equal “number”
Furthermore this is approved by the SharePoint logs:
In that case we always get the note “Setting ParentID to” at the logs (we see it if turns on Verbose for “Project Server” -> “Sharepoint Integration” category).
So at any case of publishing project’s plan we always get that note at the logs for tasks that have Parent task, and we have Parent for all of them EXCEPT the ROOT one, exact logs represented further:

The following is the complete Method’s code from the corresponded reflector:

bool flag = false;
int index = taskDS.Tables[0].DefaultView.Find((object) DataRowExtensions.Field<Guid>(row, "TASK_PARENT_UID"));
if (index >= 0)

int num = -1;

if (nullable.HasValue)
try
// STEP 1
num = this.GetCachedListItemByUniqueId(listItem.ParentList, nullable.Value).ID;
catch (ArgumentException ex)
if (redoEntries != null)
if (!redoEntries.ContainsKey(DataRowExtensions.Field<Guid>(row, "TASK_UID")))
redoEntries.Add(DataRowExtensions.Field<Guid>(row, "TASK_UID"), listItem);
//STEP 2
if (num != -1 && ((SPItem) listItem)["ParentID"] != (System.ValueType) num)
((SPItem) listItem)["ParentID"] = (object) num;
ULS.SendTraceTag(845443U, (ULSCatBase) ULSCat.msoulscat_PS_ProjectSharepointIntegration, ULSTraceLevel.Verbose, "Setting ParentID to {0}", new object[1]

//STEP 3
flag = true;
else if (((SPItem) listItem)["ParentID"] != null)
((SPItem) listItem)["ParentID"] = (object) null;
ULS.SendTraceTag(2495056U, (ULSCatBase) ULSCat.msoulscat_PS_ProjectSharepointIntegration, ULSTraceLevel.Verbose, "Resetting ParentID to null");
flag = true;
return flag;
Any thoughts about it would be much appreciated!
