Stacking 3750 switches with EMI and SMI versions

Hi!,
Is it possible to have in a stack Catalyst 3750 with EMI version and Catalyst 3750 with SMI?. In my case, it is a WS-C3750G-12S-E with WS-C3750-48PS-S. I didn't find clear information about this issue. I know different major releases are not compatible but nothing is mentioned about the feature set.
Thanks,
MONICA

Hi,
It's possible but not recommended. If you decide to do this you should buy 2 EMI so that if the master fails the backup can still route traffic. (Having 2 EMI is TAC supported, even if the rest is SMI - not sure about just having one EMI and one SMI)
HTH - plz rate if useful.
Andrew.

  • Stacking 3750 switches

    I have a question, I have two c3750 in production alread and would like to stack them into one switch. My question is can you stack two switches that are already in production together? If so how, do I need to remove the IP address and the hostname of one then stack them? Any help would be appreciated.
    Frank

    Yes you will only need 1 ip and one hostname to manage the entire stack . If you want a particular switch to be the stackmaster for the stack you will need to set your priorities for the switches . Good page for 3750 stacking.

  • Peer-Switch with vPC and non-vPC Vlan Port-Channels

    Hi,                 
    in a design guide i have noticed that it is best practice to split vPC and non-vPC vlans on different inter-switch port-channels. Now, if i want to use the Peer-Switch function, but the port-channel interface of the non-vPC-vlan channel moves into blocking state. The option spanning-tree pseudo-information has no influence. Is peer-switch possible in my kind of topology?
    Greeting,
    Stephan

    I believe absolutly possible. specifically coz peer-switch and spt pseudo-info are specific and local to cisco fabric services running as part of  vpc technology. Personally me has lab with vpc-domain compounded of 2 N5Ks. They are peer-switches with spt-pseudoinfo and they have MST running on non VPC links independantly from vpc.

  • Doubt abt the EMI and SMI images on 3560 switches

    hi all i have a silly doubt. if i buy a 3560 with the SMI image loaded in it. and then i install a EMI image in it then will it support the EMI images. i mean my main doubt is is it just abt the images or do we need a license on the switch for running a EMI image in it.
    regards
    sebastan

    in short, YES, you can load an EMI on your 3560 as it's currently configured.
    (no license key or such to activate is required)
    if you have an SMI switch that can support EMI image, as in most cases, then you can upgrade to the EMI image with the EMI software downloaded from cisco.com.
    technically, you are required to have purchased an EMI license to be legal to use the image.
    (although you can load an EMI image at anytime)
    the license is NOT installed anywhere, just a piece of paper that confirms you paid for the software.
    if you need further information on licensing please contact cisco licensing at http://cisco.com/go/license (requires CCO login) or call 800.553.2447 and ask for 'licensing'.

  • 2960-X stacking, 5 switches with interwoven 0.5 M cables

    I am trying to understand how to connect 5 switches using 0.5 M cables only.  I have read this "best practices" document, but it leaves some unanswered questions.
    http://www.cisco.com/c/en/us/products/collateral/switches/catalyst-2960-x-series-switches/white_paper_c11-728327.pdf
    I would normally just daisy chain the switches and bring a connection from the bottom switch back up to the top to create a "ring" topology.  But the documentation also states that switches can be connected with "interweaved cables".  It makes no statement as to what if any performance considerations should be taken into account when designing stack interconnections, or whether this interwoven topology creates any operational complications.  The only requirements that I have seen is that each switch must have 2 operational FlexStack links in order to be fully redundant and to fully utilize all available bandwidth.  Does anyone have any guidance in this area?
    Assuming no negative consequences by using the "interwoven" topology, does this make sense?
    Thanks,
    -Jeff

    Well it probably wouldn't be confusing if I could find a clear set of ground rules.  The documentation mentions "FlexStack protocol", but the discussions seem to indicate that this is a control plane protocol. Do the stacking modules operate as ethernet bridges when making forwarding decisions like any other switch port?  If the answer is yes then at least I understand the principal of operation.  But now if you throw multi-chassis etherchannel uplinks into the mix divining general layer 2 paths becomes a little murky.
    Although now that I look at it, using this cabling has an advantage over a straight ring topology.  Once a frame hits the stack it is never more than 2 hops away from it's destination.  With daisy-chained switches it could be up to 4 hops.  This is of course assuming standard 802.1d-like forwarding.  This may be an invalid assumption.  I don't see any way to get spanning tree info for the stack ports.
    (EDIT:  standard ring topology would also have a maximum of 2 hops to any switch, not 4)

  • Best way to manage large library with AAC and MP3 versions of files

    I have a large library of music. I listen to music through iTunes and iPod/iPhones, but also other devices which only support MP3, and not AAC. I typically convert iTunes purchases to MP3, but I'm left with two copies of each song in the same folder. I'm looking for recommendations on the best way to manage what would essentially be a duplicated music library - a high quality version I use with my iTunes/ipods, and a lower quality MP3 version for the devices that only support that format.

    I have had a similar problem. I have all my music residing on a NAS where I access it from iTunes (for managing my iPods/iPhones) and a Tivo PVR (which is connected to my house stereo system.) The problem is that Tivo does not recognize AAC. So I've used iTunes to create mp3 versions of all my purchased AAC music. Because the NAS is set as my iTunes media folder location, iTunes puts the mp3 copies back into the existing folder structure (which it keeps organised) on the NAS. Tivo accesses the NAS directly, over the network. But iTunes also puts the additional copy into the iTunes library which leaves me with multiple copies of the same songs on iTunes AND my iPods. Having multiple copies on the NAS (mp3 for Tivo and AAC for iPod) is OK: I've got plenty of space on the NAS and the Tivo doesn't 'see' the AAC files.
    The solution I'm planning to implement is to delete the mp3 entries from the library as soon as I create them (leaving the files in the media folder.) But what I'm looking is for a way to automatically select the mp3 copies (for deletion) from the existing duplicates list. Any ideas?

  • Installing a package with "-S" and few versions available

    What if I install from some repo "pacman -S app" and there are few versions of "app" and I don't concretize it for pacman? What version will it install? I know that with "-U" I can tell it what version to install. But how does "-S" behave without concretizing?

  • Stacked area chart with start and end dates

    Hi,
    I'm trying to create a stacked area chart from values that have a start date and an end date. I'd like the area to be drawn as a sum of the values at each x-axis date interval. So if I have data like:
    Start              
    End               
    Value
    2013-01-01      2015-01-01     
    100
    2013-09-01      2014-01-01     
    200
    2013-01-01      2016-01-01     
    300
    What I need is to have the chart show the area y-axis at 400 from the start up to 2013-09-01 where it would rise to 600. At 2014-01-01 it would drop back down to 400 and at 2015-01-01 it would drop to 300 until the end.
    Is this possible without calculating the sums for each date beforehand?

    Hi Erba,
    According to your description, it seems that you need add Start and End fields with the same level (without group relationship) to the x-axis in stacked area chart. As per my understanding, we couldn’t add multiple fields in one group at the same level.
    So in order to work around this issue, we can modify the dataset to combine the Start and End field into one filed, then add the new filed to x-axis. For more details, please refer to the steps below:
    Modify the dataset with the following query statement:
    select Start as date , Value as value
    from table_name
    union
    select [End] as date, (0-Value) as value
    from table_name 
    Drag a Stacked Area Chart to design surface.
    Insert value field to Values pane, then modify it with the expression below:
    =runningvalue(Fields!vlaue.Value,sum,"DataSet_name")
    Insert date field to Category Group pane.
    The following screenshot is for your reference:
    If there are any other questions, please feel free to ask.
    Thanks,

  • Software Switcher with FMLE and FMIS

    Hello Readers,
    I wanted to know if there is any facility to use Software Switchers along with FMIS
    The Situation:   I am streaming multiple streams using FMLE from one place and at the receivers end, the client receives only of the streams at a time.
    So I wanted to apply switcher so as, I could stream only one stream from FMLE at one time
    I have explained the scenario in the attached image.

    I don't think there are any software switchers as you have described (at least, none that I've seen). If the switcher is between FMLE and FMS, the switcher needs to be able to receive RTMP connection from FMLE, and make an RTMP connection to FMS.
    That said, you can achieve what you described with actionscript. The switcher (as in your diagram) would be the FMS application. Each FMLE would publish a stream to the FMS app, and you'd write server side methods to select the FMLE stream to show. Your FMS code would play the selected stream over a server side stream, which your clients would subscribe to.
    There's an old (yet still valid) example here:

    you can redraw the program to see if the update was performed to Muse DC Correctly or use the old version Which at least gave no problems with image galleries?
    thanks greetings

    The problem I am having is this: The phone and message portion of my palm stopped working. I called my provider and they told me I needed a new sim card. I got a new one and put it in and still experienced the problem. It was a complete stoppage. I could call one out of 10 tries and a message or two came through but late. I then called Palm and they walked me through a hard reset and the phone started working, ...but only for the evening. Now again it is at the same place. I have hard reset it several times and occasionally it will work once or twice after that. ....

  • Two srw switches with vlans and pfsense gatway

    Hi,
    I've got a bit of a problem that a can't seem to get a handle of things.
    I've got two srw 48 port switches that I would like to link together  and then on to the pfsense box.
    First I'd like to connect the two switches to see if everything works and then on connect the pfsense box.
    Now I would be very great full if someone with a bit more experience with VLANs would be so kind to walk me trough the procedure of creating VLANs, configuring them to ports on the switch and connecting the whole thing to another switch.
    This is what I've done so fare.
    1. I created 3 VLANs on both switches (VLAN2-office,VLAN3-WiFi, VLAN5-VoIP). I've created these VLANs with the same tags on all the devices.
    2. I configured the ports that connect the switches as trunk. (I can't seem to be able to configure anything else on this port. Is there something else I should configure on these ports?)
    Now as fare as I understand the documentation the VLANs on each switch should now see each other.
    I'm still not sure on how to configure a physical port to one VLAN. After creating the VLANs on both switches and connecting them trough the trunk port I set ports 10-20 to VLAN2 by going to VLAN Management -> Ports to VLAN I selected VLAN2 and marked ports general and untagged and saved the settings. I repeated the procedure on the other switch. Now if I stuck my network cable into one of this ports I didn't get an IP anymore form the DHCP witch means that they were on a different VLAN than the other ports so I setup another router to act as a test DHCP with a different IP range as the main DHCPto see if it works. Now when I connectedthe test router to one of the ports in VLAN2 and my PC to the same VLAN2 port I got the test IP no problem. But when I connected the PC to the other switch VLAN2 port nothing happened until I connected the test DHCP to one of the VLAN2 ports. So clearly the switch VLANs are not communicating.
    Now I don't know did I forget something, made a mistake with some setting or I just don't know what I'm doing because I think I need to get the VLANs between switches working before tackling the pfsense connection.
    I would be really great full if someone explains to me how to set these VLANs up so that they would work between switches.
    Thank you for your help.

    Hi,
    I was successful and I did exactly that. I put all VLANs on trunk ports and the switch to switch to pfSense started to work.
    The only thing that gave me some problems was the end port(port connecting to the device pc, phone, printer) configuration. I was under the impression that the port was supposed to be in general mode and tagged. But I figured out that the port is supposed to be in access mode and untagged and only a member of one VLAN(the one I wanted it to connect to).
    Anyway all is working now and I've figured out all the kinks. 
    So thanks guys for the help.
    Nice day to all.
    Bye

  • Safari bug with privoxy and keychain (Version 3.0.4 (523.12.2))

    Hello,
    I use privoxy to forward some requests to another proxy server located at the university, in order to access online some publications. Of course, this requires a password, which is stored in the keychain as "localhost (<university login>)", for the location "http://localhost:8118". Now, this works fine with Camino; but Safari would store the same password again (which it does for every password; very annoying), and from that moment, a lot of programs want to access this password: the apple SoftwareUpdateChecker, Adium, Shimo, etc.
    Looks like a MacOS/Safari problem to me - all these applications, I think, want to access the web, hence use the proxy server I set. And they find a keychain password for that proxy. But - why do they want to use a password they are not prompted for? I'm quite sure that these programs don't request URLs for which I set a forward to the university proxy.
    Camino, by comparison, prompts me to confirm the (stored) password only when I access one of the "forwarded" URLs. As for Safari, I can't tell, maybe it sends the password to privoxy all the time - but again, how, if it is not prompted for any PW?
    Has anyone experienced this?
    Regards,
