How many BGP peers does the 3548 switch support?

Is it possible to run more than 40 peers on a single switch? What is the limitation if not?

Hi ,
 You can have 40 BGP peers , IPV4 unicast routes handled by hardware is only 24000 .Enusre all your BGP peering routing updates is within this limits .

  • How many external displays does the 15 inch support?

    I spend 90% of my time at a desk developing, using multiple monitors.  My current Windows system can support up to 4 displays, normally I run with 3.  I was wondering how many external displays one can hook up to the 2.3GHz Macbook Pro.  I need at least 3 displays while still having a thunderbold for external drives and eithernet.  Does the Mini DisplayPort to Dual-Link DVI Adapter allow splitting the single to two different monitors?  Other then the Thunderbolt display, is there a way to get multiple monitors out of one Thunderbolt port?

    From http://support.apple.com/kb/SP690 -> "Simultaneously supports full native resolution on the built-in display and up to 2560 by 1600 pixels on up to two external displays, both at millions of colors".
    But there may be ways of driving three monitors - maybe someone with a Retina Display model will jump in. I know that on my 15" 2011 model, I can only drive two Apple Thunderbolt Displays.
    Good luck,
    Clinton

  • Does the ME3400 switch support MDI/MDI-x autocross

    Does the ME3400 switch support MDI/MDI-x autocross? I recently experienced  a situation where when the switch was set to a fixed 100 Full duplex and the outboard device selected the wrong pair, they would never link.
    Is MDI/MDI-x only supported on auto-negotiation?

  • How many email accounts does the iphone4 support?

    Wanted to know how many different e-mail accounts will the new iphone4 support?
    thanks

    If there is an email account limit with the iPhone or with the current firmware version and with any previous firmware versions, I'm not aware of it. You shouldn't have any problem creating and accessing 6 email accounts.

  • How many regular pianos does the newest garageband have? I bought the extra content and I still only have one piano and not even 1500 loops as I was promised. Did my download mess up?

    I just purchase a new retina mbp and I bought and downloaded the extra add on for garageband, and before it I only had 1 piano, and after I did the 10 gig download I still only had....1 piano and not even the 1500 loops it said I would, as well as if I go to restore purchases for garageband, it says I only downloaded half of it. Can I redownload it correctly?!? Or didn't download all of it? Also I tried download the other half and it didn't work! Please help!

  • How many memory banks does the new HP Pavilion Notebook 15 p200na have?

    I think the laptop must be a very new modle as there are no reviews on it so I cannot see if it has more than one RAM memory bank; the listing says it comes with one 8GB RAM but I can't see if there is also an empty slot. Thanks,

  • How many install disc does the Mac Pro come with? Snow leopard is preinstalled.

    I have an application install disc that has ilife and a few others but I'm thinking that I may have disc for the system and optional installs somewhere.
    I bought the mac pro tower in march of 2010.
    I cant remember what came with it.
    I thought I would ask before I start digging around in my messy office!

    Two Disks: Install Disk & an Applications Disk. You can call AppleCare, if you lost yours, and for a small fee they will send you one.

  • Does the SLM224G switch support port-based VLAN's?

    I am looking for a simple solution to create two LAN's. One for my own and one for my customers, who will be able to use desktop PC's with internet access. I have only one internet connection (DSL over ISDN) and wil not getting another just for my customers.
    My own network should not be accessible or visible to users who are using the customers-PC's. The other way around is allowed, but not really necessary. My setup requires me to hook up the switch to the (ISP) router, and that router just has one LAN port not able to do anything related to VLAN's.
    I read about port-based VLAN's here, where it is stated that creating seperate LAN's is just putting ports into VLAN's on the switch, nothing else needs to be done... However, they used a NetGear smart switch.
    I checked out Cisco's SLM224G as it is affordable, has 24 ports (instead of 8 for the NetGear) and should support VLAN's. I have read a lot about VLAN's, including:
    "- Port-based VLAN's means that you can reconfigure ports to be in different VLAN's. Port-based VLAN's do not confirm 802.1q VLAN support.
    - 802.1q VLAN's means that you can tag VLAN's with 802.1q headers to create a trunk between two devices that carries frames for multiple VLAN's. 802.1q VLAN's confirm that there is also Port-based VLAN support."
    I known from the spec sheets that the SLM224G supports 802.1q (tagged) trunking. So it should, given found text above, also support port-based VLAN's.
    My question is whether it indeed will support port-based VLAN's?
    Am I able to use it directly behind my ISP's router and create two seperate LAN's?
    If so, one extra question: how are the PC's behind the switch (inside the two VLAN's) get their IP-adresses from the ISP-router? Or will it service only one of the two LAN's and should I install a DHCP-server in the other LAN?
    Any information is very welcome!
    Thank you.

    Thanks for your responce, mr. Carr.
    I have read more about vlan's and their setup. I think the article about port based vlan's was lacking some information about the router/firewall. May be it was set up to work with different vlan's from the start. Strangely, in the text it is said that nothing needs to be set up besides the (Netgear) vlan-capable switch.
    So, from your response and other texts I learned I needed a vlan-capable router. I have to say that I need to be able to manage a server on the LAN from the outside (internet). I already tried to set up a Cisco/Linksys WRT54G router behind the ISP's (ZyXel) single LAN-ported router and that would not work at all (even when the Linksys was set in router-mode). I lost the connection to internet setting it up that way. I even tried to setup the Linksys in the DMZ of the ZyXel, with no luck. I was unable to set that up with working internet-access form the LAN. So I was not too happy with the suggestion to set up a (second) vlan-capable gigabit router behind the ISP's router....
    Eventually, I bridged the ZyXel to get rid of the double NAT/gateway mode of the two routers as routing mode did not work on the Linksys. The Linksys is now getting the WAN-ip from the ISP on it's WAN port and I furthermore used DD-WRT's firmware to enable the build-in vlan-capabilities of the Linksys.
    Now I have set up the Linksys with two vlan's and I bought the SLM224G as an inexpensive manageable 24-port vlan-capable switch to provide the number of ports I needed. I devided the SLM in two vlan's and used two wires from the Linksys to the SLM. So the SLM does support port-based vlan's by simply setting up two ranges of ports with different PVID settings. Trunking and 802.1q tagging isn't needed that way. I know I could have used two dumb switches to get two separate subnetted networks, but this way I get just enough ports in a single device where I have ample space to put it.
    Anyway, thanks for helping me understanding the way vlan-capable switches work.

  • How many devices (iPods) does Wi-Fi sync support simultaneously in iOS5?

    I have 3 iPod Touch 3gen/4gen in my house.  They are setup and all work with WiFi sync individually but I can only get two to show up at any one time in iTunes and I'm not sure how it manages to decide which iPod to show and which one to not show.  Is two the maximum number of devices to show in iTunes 5 via Wi-Fi at once?  I want to make sure that they all sync at least once a day or so.  If you have multiple devices are they 'rotated' somehow by iTunes or am I gonna be stuck connected the 'odd iPod out'  (which varies from time to time) via cable to PC?.
    I want to pick up two more touches which may make the issue even more confusing.  I'd like to get it settled for three before I buy my other two.
    WIndows 7, latest iTunes.  IPod firmware all up to date and all are setup in iTunes and in the iPod's settings to sync via Wi-Fi.  Again, all work individually but only two show up on the left hand column in iTunes.
    THanks!!  Happy Halloween!!

  • How many concurrent connections does WSA S670 appliance support.

    Hi All,
    Good Day!
    We have an issue with our Ironport WSA S670 appliance. We have around 35K users and have access to sites like facebook.com, youtube.com etc.
    The issues is that at times certain sites are not accessible via proxy. For example we cannot access youtube.com, google.com etc while we can access msn.com, espn.com etc. Moreover when we try to bypass the proxy and access the sites directly all the sites works just fine.
    This issue has been repeating many times and we checked the internet link, proxy etc for any issue. In the meantime the issue gets resolved mysteriously.
    The total number of connections at these times are more than 20K. The CPU utilization never goes beyond 15% but the memory is always between 70 to 90% utilized.
    What is the maximum number of connections WSA S670 appliance support? Is there any configurable limit for the connections that can be established? Will it cause any issue if a lot of users are watching videos on youtube.
    Also the proxy is working in one-armed design. Will that cause any issue?
    Please suggest.
    Cheers,
    Faiz

    Hi Faiz,
    There are not any known issues in terms of URLs failing. I would perform a packet capture on the WSA. See my instructions below:
    In order to obtain a simultaneous packet capture from the WSA & PC you will need to log into the GUI ->Support and Help -> Packet Capture -> Edit Settings -> Select the radial button No Filter.Please send me a packet capture from the WSA unfiltered. You will need to install wireshark on the PC or laptop you are testing from. It is a good idea to start the wireshark program from the PC first.  I would recommend using www.iana.org as a test as it uses only on IP address.
    When you have the captures completed I would first look at the WSA packet capture and use the following filter in wireshark http contains "www.iana.org". The various streams of communication will populate in the wireshark display. What you want to focus on is the streams that show the IP of the WSA and the IP of www.iana.org 192.0.32.8. We should see the following when you right mouse click the packet which shows the IP of the WSA going to the destination IP of www.iana.org:
    WSA IP -------SYN-----> www.iana.org IP
    WSA IP <--SYN/ACK-- www.iana.org IP
    WSA IP -------ACK-----> www.iana.org IP
    If you see this instead:
    WSA IP -------SYN-----> www.iana.org IP
    WSA IP -------SYN-----> www.iana.org IP
    WSA IP -------SYN-----> www.iana.org IP
    WSA IP -------SYN-----> www.iana.org IP
    Then you have a problem in your network.

    NVIDIA GeForce GT 650M with 1GB of GDDR5 memory and automatic graphics switching
    Dual display and video mirroring: Simultaneously supports full native resolution on the built-in display and up to 2560 by 1600 pixels on up to two external displays, at millions of colors
    Thunderbolt digital video output
    Native Mini DisplayPort output
    DVI output using Mini DisplayPort to DVI Adapter (sold separately)

  • My playlists show how many titles are in the playlist but does not show the list of titles

    my playlists show how many titles are in the playlist but does not show the list of titles. Is there a setting that I hit by mistake to hide the content?

    Perhaps you have made one column extra wide and the window isn't currently showing the Name column. Try resizing columns, turning off those that you don't need, or scrolling sideways.

  • How many route entries does 3945E or/and 3900 ISR G2 support

    hello guys:
    I have a question concerning about how many ospf and bgp route entries does 3945E isr g2 router support?
    cheers
    tony xi

    Tony,
    This question can't be answered in general. It depends foremost on the amount of available memory in the router. With 256MB of RAM, you can expect that the router can manage roughly tens of thousands of routes. The full BGP routing table (not the BGP database) consumes around 70MB, however, the full BGP RIB on one of the route-views project routers consumes over 1100 MB of RAM (this also depends on the number of BGP peers and the amount of data sent to it by individual BGP neighbors). The exact number is impossible to determine, as it depends on the amount of other control information that the router has to store in its RAM - for example, OSPF LSDB, BGP RIB, the CEF and adjacency tables, etc. etc. etc.
    So you can assume that 256MB of RAM should be working for deployments up to the order of tens of thousands but this has to be taken with a very, very rough and unreliable estimate.
    Best regards,
    Peter

    If possible, I would suggest that you upgrade to the latest release: 11.2.0.2.0. It has many bugfixes and enhancements.
    There is no limit on the number of optionals per query. I suspect that the use of the same new variables (?avgrec and ?maxrec) in the parallel optional clauses is the reason you are seeing the error in this particular case. If you use different variable names does the error go away? If needed, you can use a coalesce in the outer SQL SELECT to get the same behavior as before (e.g. COALESCE(avgrec1, avgrec2) as avgrec).
    Thanks,

  • How many ways to edit the data in PSA?

    HI
    How many ways to edit the data in PSA? Can we edit both transaction, master data also?

    Hi.......
    Yes yo can edit data in PSA for both Master data and transaction data.......the only diffrence is that in transaction data you have to delete the request from the target before editing......and in master data no need to delete any request....directly edit the PSA........
    To edit PSA......the most easiest method has alsredy mentioned ............
    But suppose you don't have authorization to edit the data in PSA but still you want to edit then you can follow the process mentioned below..........
    You can call up the function module RSAR_ODS_API_GET with the list of request IDs given by the function module RSSM_API_REQUEST_GET. The function module RSAR_ODS_API_GET no longer recognizes InfoSources on the interface, rather it recognizes the request IDs instead. With the parameter I_T_SELECTIONS, you can restrict reading data records in the PSA table with reference to the fields of the transfer structure. In your program, the selections are filled and transferred to the parameter I_T_SELECTIONS.
    The import parameter causes the function module to output the data records in the parameter E_T_DATA. Data output is unstructured, since the function module RSAR_ODS_API_GET works generically, and therefore does not recognize the specific structure of the PSA. You can find information on the field in the PSA table using the parameter E_T_RSFIELDTXT.
    RSAR_ODS_API_PUT
    After merging or checking and subsequently changing the data, you can write the altered data records into the PSA table with the function module RSAR_ODS_API_PUT. To be able to write request data into the table with the help of this function module, you have to enter the corresponding request ID. The parameter E_T_DATA contains the changed data records.
