Difference between bridge mode and routed mode on CSS

Hi,
Could some one tell me the difference between routed mode and bridge mode.
Regards
Neha

Hi,
routed mode:
The CSS acts as a router, it routes packets from the client to the server. The server has the ACE configured as default-gateway.
There is a client-side VLAN and a server-side VLAN. These VLANs have different subnets.
Bridged mode:
The CSS acts as a bridge, it switches frames from the client to the server. The server has the upstream router configured as default-gateway.
There is a client-side VLAN and a server-side VLAN. These VLANs have the same subnet, but different VLAN IDs. The ACE bridges the client traffic from the client-side VLAN to the server-side VLAN.
Bridged mode would be most used in case one cannot change the servers IP addresses, or if address space is an issue.
Hope this helps.
Kind regards,
Dario

  • Bridge mode and router mode

    hello,
    I want to understand the basic operation, difference and advantages of both Bridge Mode and Router mode?
    i also want to know in which case i should go for Bridge mode and Router mode?
    regards
    Devang

    It realy depends on your requirements.
    Mainly bridge mode is used for multicast support, Multiple DMZs + FWSM, server initiated connections or for seemless migration from previously installed "bridged load balancing environment".
    Some of the differences are
    In bridge mode you do not need additional config for "Direct server access" / "Server Initiated connections"
    Broadcasts are dropped in routed mode whereas they are bridged in bridge mode.
    LB functionality is same in both modes.

    Expert Mode Infotype Maintenance: This interfaces allows you to edit individually selected objects in OM (Org Units, Positions, Jobs) via infotypes. 
    Expert Mode: Simple Maintenance Interface (PPOM_OLD) is used to quickly create a new Organizational Plan. As a user, you can pretty much maintain large volumes of data very easily ( i.e create several objects simultaneously), without having to go through the more "Performance Intensive" Org and Staffing interface.
    In accessing the Simple Maintenance interface to create your org structure, the initial screen requires you to specify which evaluation path you want to create your org structure.
    Organizational Plan: This is what provides you with a complete picture of an enterprise's environment. It comprises elements (objects like Org Units, Positions, Jobs etc) which are used as building blocks for creating an Organizational structure.

  • Difference between maximum concurrency and batch mode in JDBC

    Hi All,
             Could som one tell me the difference between maximum concurrency and batch mode in receiver JDBC adapter?
    Regards,
    XIer

    Hi,
    The Max Concurrancy and Batch mode are used for performance tunning for JDBC adapter.
    Max Concurrancy is possible upto 5 only. so even if you will be taking up 10 it will by-default take 5.
    The number of records being processed depend on the size of each record. for e.g Per minit XI Is Processing 50 Records,It will Take lot of time to process all Records.
    So if you set Max concurrancy as 5 then at time 5 messages will be processed simultaneously.
    In Batch mode it will, collect the multiple SQL statements that will be created for records to be processed and processed at a time. It will  improve performance considerably.
    But Batch Mode is possible with only INSERT, UPDATE, DELETE etc.
    The Stored procedures can be executed with max concurrency
    Thus it completely depends that on the no of records to be processed at a time and volume of Mesasges.
    Thanks

  • Difference between bridge-group and VLAN

    Hi all,
    I don't understand very well the difference between bridge-group and VLAN...
    Could someone explain me or give me a site which could help me?
    Thx U by advance!

    Khay
    bridge-group is used on a router to enable bridging on an interface. In terms of functionality a bridge-group is very similar to a VLAN. For example if you create bridge-group 1 and assign it to interfaces FastEthernet 1/0 and 2/0 and you create bridge-group 2 and assign it to interfaces FastEthernt 1/1 and 2/1 it is like creating 2 VLANs. Devices in bridge-group 1 (interfaces 1/0 and 2/0) can communicate with each other but not with devices in bridge-group 2 (intefaces 1/1 and 2/1).

  • Re: Difference between switcher component and router activity

    Hi all,
    Here i want to know the difference between switcher component and router activity.
    Can anybody give the difference between them or suggest any blog for this.
    Thanks,
    Syam

    <af:switcher> component is an ADF Faces component. You can use it within (the source of) a JSF page or fragment to include a particular group of other JSF components depending on the switcher expression's value.
    Router activity is not a JSF component, i.e. you cannot use it within a JSF page of fragment. It is an ADF taskflow activity. You can use it as an activity within an ADF Taskflow to route transitions between some other activities in the taskflow depending on the router's expression.

  • Difference between production version and routing

    hello pp experts,
                            why do we create production version, and what's the difference between production version and routing?

    Dear sarfaraz lodhi ,
    Production version is a combination of BOM & Routing in the case of Discrete Manufacturing and it's a
    combination of BOM & Rotuing/Rate Routing in the case of Repetitive Manufacturing.
    Created either through MM02 by selecting MRP4 view or else through C223
    A production version determines the various production techniques that can be used to produce a material.
    It defines the following information:
    ·        Alternative BOM for a BOM explosion
    ·        Task list type, task list group, and group counter for assignment to task lists
    ·        Lot-size restrictions and period of validity
    A material can have one or more production versions.
    Routing contains the set of operation that's required for producing a product either a HALB - Semi-
    Finished product or else a FERT - Finished Product.
    The T code for creating Routing is CA01.

  • The difference between VTP server and transparent mode on Catalyst Switch.

    Hello 
    I have a question about the difference between VTP server mode and VTP transparent mode on general catalyst switch.
    Basically VTP server mode can create and modify VLAN configuration but  actually there is not any VLAN configuration through running-config, is it true?  When I checked it on Cat3550, certainly there is not VLAN configuration on VTP server mode. But VTP transparent can create VLAN and configuration but does not synchronize with other switch VLAN status. I appreciate any related information and reason of the VTP server mode specification, thank you very much.

    This indicates that vlan never created in server mode nor learnt from another switch as revision no is 0

  • What's the difference between OpenGL advanced and normal modes?

    I get that Basic mode uses the cpu and Normal uses the gpu, but what exactly does Advanced mode do?
    The description says that it uses as much of the GPU as Normal Mode does, but adds "advanced techniques to improve drawing performance."
    Has anyone seen one of these advanced techniques  in action or know of a list of these mysterious improved capabilities?

    What CC said... Imagine a shader having say a length of 32 discrete instructions/steps vs. one with 16... The 32 one will concatenate specific operations in one step and may thus be more optimized, but will not work on a card that does not provide those 32 shader cores, since it could not be executed in one clock cycle. Then you would use the 16 one with instructions being split across 2 cycles... That's all there is to it and for al lintents and purposes mostly irrelevant and unimportant to the user...

  • Difference between Buffered Read and Read Mode on DataSocket Open

    What are the behavior differences when opening a DataSocket connection with a Buffered Read verses Read?

    Mlenz,
    You can learn about buffering data from our website, or in the LabVIEW help.  By using the Datasocket Buffered Read, you are enabling Client-side Buffering.  If you do not use a Buffered Read, then the LabVIEW does not store the values in a buffer, which are written when the value changes.
    Hope this helps,

  • What is difference between TEXT mode and BINARY mode?

    Hi,
              What is difference between TEXT mode and BINARY mode? In TEXT mode what is "ENCODING DEFAULT".
    OPEN DATASET wl_filename FOR INPUT
                              IN TEXT MODE ENCODING DEFAULT.
      OPEN DATASET wl_filename FOR INPUT
                              IN BINARY MODE .

    Hi vishnu,
    1. files like .TXT files are considered to be text,
       and other files like .EXE . DOC etc are binary files.
    2. In text files, after each line, there are two
       internal binary characters
      one for line feed and another one for newline.
    3. But, we don't have any meaning for it,
       when we view such files in notepad, for eg.
       Hence, to only get the understandable content,
       we should open such TXT files, in text mode.
      (we can also open them in binary mode,
      but we will get two extra characters after each line,
       and such two extra characters are meaningless
      for interpreting the text)
    4. In binary mode, each byte by byte is considered,
       without any meaning.

    amit m.

  • Difference between open loop and closed loop mode when finding the index on a stepper motor axis.

    I have a test system which uses a PXI-7352 motion controller with a MID-7602 stepper motor drive to position a 200 step/revolution stepper motor with an attached 1000 line encoder.  The MID-7602 is configured for 64 microsteps per step, giving 12,800 microsteps and 4000 encoder counts per revolution.  The system is controlled using LabView 7.1 and NI-Motion 6.13.  To home the motor, I've defined a sequence in MAX which first finds the reverse limit switch and then moves forward to the encoder index pulse.
    When finding its reference in open loop mode, the system its reference at the same microstep each time.  When findings its reference in closed loop mode, the system finds its reference somewhere within about a 20 microstep wide range.
    I hope somebody out there with more experience with this controller can describe the difference between finding the encoder index in open loop mode and finding the encoder index in closed loop mode. 
    Thanks,
    Mark Moss

    Hello Mark,
    I suspect that the behavior you are experiencing has today
    with the resolution difference between your encoder and your
    microstepping.  Let me illustrate with an
    example:
    Example Setup
    Stepper
    Motor
    NI
    Motion Controller
    10
    steps per encoder pulse (Every 10 steps the controller gets an encoder
    pulse, therefore positions 0-9 all appear to be 0 to the controller)
    The
    system has a maximum of 3 pull in moves set
    Open Loop Scenario
    The
    system is commanded to go to position 9.
    The
    controller sends out 9 pulses.
    The
    motor moves to position 9.
    Closed Loop Scenario
    The
    system is commanded to go to position 9.
    The
    controller sends out 9 pulses.
    The
    motor moves to position 9.
    The
    controller checks its position and sees that it is still at position 0
    because it has not received an encoder pulse.
    Because
    the controller thinks it is still at position 0, it sends another 9 pulses
    as its first pull in move.
    The
    motor moves to position 18.
    The
    controller checks its position and sees that it is at position 10 because
    it has only received one encoder pulse.
    Because
    the controller thinks it is still at position 10, it sends1 reverse pulse
    as its second pull in move.
    The
    motor moves to position 17.
    The
    controller checks its position and sees that it is at position 10 because
    it has only received one encoder pulse.
    Because
    the controller thinks it is still at position 10, it sends and additional
    single reverse pulse as its third pull in move.
    The
    motor moves to its final position of 16.
    I believe something similar is happening with your
    application as it looks for the index pulse. 
    Because the controller does not compensate for what it perceives as
    position error in open loop mode, the motor always goes to the same commanded
    position.  In closed loop mode, the motor
    is bouncing around inside the single index encoder pulse trying to find a
    certain position.
    There are several recommendations I can make towards
    correcting this behavior.  These
    recommendations are in order of effectiveness:
    Setup
    your system so that there are more encoder counts per revolution than
    steps per revolution.
    Turn
    off pull-in moves by setting them to 0 in MAX.
    Use an
    open loop configuration.
    Play
    around with the pull in window in MAX.
    Regards,
    Luke H
