3750 metro series switch does not support dot1q trunking?

Folks,
I have a 3750 metro series switch and i am trying to use it to do inter vlan routing. I do not see an option for "encapsulation dot1q" under sub interface?? why is it not supported??
Thanks

Narvin,
if you want inter-vlan routing, the interface Vlan nn itself specify vlan.I think you confuse with router subinterface where you must specify what Vlan a subinterface must use ( and encaps type ). Encaps type ( dot1q or ISL ) is used at trunk level, and whatever trunk use you can do intervlan routing using vlan interface.

Netflow on Cisco Catalyst 3750 Metro Series Switches

Does netflow possible in 3750 metro series?

Hi Syed,
You have to first check if there is any image in switch or not so that you can manually boot from switch: prompt but as you said there is no image in the switch you have to go for xmodem procedure to upgrade the switch.
Have a look at this link and just follow step by step instructions and you will be good to go

Navin,
The 3750 Metro series switch does not support Layer 3 trunks; you cannot configure subinterfaces or use the encapsulation keyword on Layer 3 interfaces. The switch does support Layer 2 trunks and Layer 3 VLAN interfaces, which provide equivalent capabilities.
For more information, see the note under Table 12-5 on this page: http://www.cisco.com/en/US/products/hw/switches/ps5532/products_configuration_guide_chapter09186a00803960dc.html#wp1326724.

3750 Metro ethernet switch

Folks,
I have 6500's at the core and want to use the 3750 at the PE. My question is the following:
1) 3750 would do Q-IN-Q.
2) Once the packet reaches the 6500(sup 720) running MPLS. What happens to the frame. Do i use xconnect to transfer the frame to the appropriate PE?
Just confussed about how does the PE use the Q-IN-Q information to direct it to the appropriate PE?
Sample config would be highly appreciated.
Thanks

Cisco DCNM 6.2 does not support most of the switches in my network

Hi All,
I have just installed Cisco DCNM 6.2. I have run a discovery using SNMP v1 my core switch which is a 3750G stack. DCNM discovers all my switches but does not support the 2960 and 3750 switches. The only switches I can select to manage and are supported are a 4510 and 3550. I have also run another discovery using SNMPv3 on a different core switch (Nexus 3K) at one of our remote sites. DCNM found all the other 2960s in that network but I can only select the two Nexus switches in the core to manage. What do I need to do to be able to manage all my switches switch?
Thank you in advance.

Hello,
DCNM is meant for data centre network management and as such only supports the MDS, Nexus and the 6500 series switches, see the RN under supported Cisco platforms and software:
http://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/6_x/dcnm/release/notes/dcnm_6_2_5a_relnotes.html#pgfId-314209
For the discovery issue DCNM should 'see' the other devices so you need to have a look at your SNMP and CDP (used for neighbour discovery on a per hop basis) settings on each of the devices.
For an software package to manage LAN/WAN environments you really need to be looking at Cisco Prime LMS.
We are going through the same problem, it would be nice to be able to manage the DC and LAN from DCNM.

I was having the same issue even with entering the following:
archive download-sw /overwrite /allow-feature-upgrade tftp://172.18.108.26/c3kx-sm10g-tar.150-2.SE7.tar
I noticed the image which was running on the switch was correct without the ".bin" at the end:
3560#sh ver | i image
System image file is "flash:c3560e-universalk9-mz.150-2.SE7"
I uploaded a fresh IOS image from CCO and made sure the image name had ".bin" at the end. Seems trivial except the error is produced through a sanity check. See below (please excuse the extra unplugging in the output):

Hi... I would like to purchase a Tablet Sony Xperia Z 2 10.1 (the last one of the Z series) and I was told that Adobe does not support Sony anymore.... I need to be able to open and read Adobe PDF files and I would like to know if this tablet can still use Flash Player...
Is there anyo who can help me with this? I asked in the shop and I was told "yes of course" , but when I contacted Sony directly I was advised to check with Adobe as apparently in the recent months Adobe and Sony haven't been getting along anymore...

You may be mixing up two entirely different Adobe products.
1. Adobe Flash Player. Needed to view web pages designed with Flash. Not needed to view PDF files. Not available for Android (not just Sony).
2. Adobe Reader. Reads PDF files. However, the Android can also read most PDF files without needing Adobe Reader.

Is there an easy way to switch from Entourage (MS Office email) to Apple email? The new MS Office does not support Entourage.

I am looking for a way to shift from Entourage (MS Office email) to the Apple system for email? The new MS Office does not support Entourage.

Philip if you can't find your answer in this forum try the Snow Leopard forum, Mail is considered part of OS X so you may have luck there.
Also you also may want ot be more specific when posting. I'm assuming because you only mention Mail all you are interested in is switching to Mail or did you have more in mind?

Mac mini on a LCD TV which does not support interlace mode

Dear all,
I am going to buy a new Mac mini and I wish to connect it to a Samsung LCD TV 37A656A1F (serie 6.
The TV manual says that it does not support the interlace mode. I then deduce that it supports progressive mode only.
My question: Does it mean that this LCD TV model cannot be used as a monitor for a Mac mini?
Please give a help to me

All computer monitors are progressive mode displays. Therefore all computers, including the mini, are very comfortable running progressive mode. It is their natural state. It is more a problem when a computer has to run interlace mode in order to support a display. That is when there is trouble. So I think you have nothing to worry about if your Samsung runs in progressive mode.

My av adaptor does not work. Tried to plug my ipad into my samsung hd tv and ipad said it does not support that accessory...help

My av adaptor does not work. Tried to plug my ipad into my samsung hd tv and ipad said it does not support that accessory...help

What ipad, which model samsung? Are you attempting HDMI, VGA, or an RGB connection. Ipad 2 supports mirroring into an HDMI at an output of 1080. Ipad 1 is limited to only a few apps capable of the output, such as Youtube.
page64,65 of the latest ipad manual has more details.
Samsungs are good and should switch with the input - but sometimes you will have to select from the menu manually.
If in doubt, contact the customer support at samsung UK.
Also check - Settings/Video, that you have it enabled for Home Sharing. Apple Id which will be your .me.com email plus your apple ID password. I am not too sure about this as I cannot remember the exact order I set things up in - but page 89 of the manual references Home Sharing for sharing ipad/itunes content on a home pc/mac - so I would think it applies to content relayed to a tv or monitor too.

Pages 5.0 version does not support pictures in header

I recently installed new soft OS X Maverick and along with this also renewed soft for Numbers, Pages, Keynote, and some more apps.
Pages version 5.0 does not support its earlier version pre-set headers and footers. All the logos (picture files) I had inserted for my company template in the header are gone and I cannot re-enter them either. Does anyone can give e a hint on how to use picture files in Pages version 5.0 templates?
This is first time in 2+ years that I prefer to use MsWord over Pages on my Mac, which is a pity.
*I have tried to get used to new soft versions of numbers and pages now for around 3 weeks but it cannot make me to change my opinion that the eralier versions were much better. Unfortunately with OS X Maverick I have to use new versions for these apps, or do I, any hints?
I already deleted once (2 weeks ago) OS X Maverick and switched back to OS X Mountain Lion (I use TM), but then decided after while to still update the op system soft to newest one available, as I've hoped that developers in Apple will come up with their soft improvements and bug fixes soon enough.
Among the other disomforts (like pages, numbers and changed tag system) Safari is much slower than with previous version.
Any hints are appreciated!
Thanks, Paul

The extraction program does not support object 0JOB_ATTR

HI all,
I'm getting the following error when execting 0JOB_ATTR extractor in R/3 system (via RSA3):
The extraction program does not support object 0JOB_ATTR
Message no. R3009
Diagnosis
The application program for the extraction of data was called up using the invalid InfoSource/invalid InfoObject 0JOB_ATTR.
System Response
The data extraction is terminated.
Procedure
Check the SAP Support Portal for the appropriate Notes and create a customer message if necessary.
I've found various threads with this error (or similar ones), but none of them are solved (or not published solution). Haven't found any SAP notes yet either, so any input would be very helpfull.
Thank you.
G.

0JOB_ATTR not in use and SAP replaced this with 0EC_CJOB_ATTR... U have to use 0EC_CJOB_ATTR to load master data for 0JOB.
Even i faced the same problem and found the following info in one of the SDN thread, and we are using 0EC_CJOB_ATTR (make sure u have data in table HRP5050).
I have sent a message to SAP asking for the solution . Below is the reply what they gave.
"This error appears because of naming conventions we have to switch the name of the Data Source from 0JOB_ATTR to 0EC_CJOB_ATTR. Please use this data source to extract the compensation job attributes to BW.
Note also that data source 0EC_CJOB_ATTR extracts data from table HRP5050.
If no data is being extracted please do the following:
If you have data in HRP5050 and still do not get any data please try the following :
1) Take over the Data Source from the business content (RSA5)again and check in RSA3 .
2) Replicate the Data Source to BW
3) Activate the Info Source again.
4) Delete any previous delta initializations for the datasource.
5) Initialize the delta again
6) Try to load data".
