Communication between 2 SG300 - 28 p with an OFFSET of the VLAN

Hello

I have 2 SG300 - 28 p without a router used for the use of the backbone.

The switches are configured in L2.

I want to configure on the two switches:

  • The default VLAN Id 90
  • A VLAN with 80 Id to access databases
  • A VLAN Id 70 to access the backup server
  • An agregate with port 25, 26, 27, 28
  • The ports 1 to 8, 13 and 20 with VLAN 80 (90UP/80 t)
  • 9 to 12 ports, 21 to 24 with VLAN 70 (70UP)

Computers that connect to the VLAN 70 won't be intended for the VLAN 70.

I would like to use the mode of access ports in VLAN 70.

Computers that connect to the VLAN 80 will not be intended for 80 of VLAN.

It seems that servers on the local network VIRTUAL 80 switch 1 can communicate with servers on the 80 VLAN on switch 2.

My problem is that the servers on the VLAN switch 70 1 access to the servers on VLAN 70 on switch 2.

I guess it is because the 90UP of LAG 25/26/27/28 configured.

Any idea to solve this problem?

The OFFSET is like any other link. It is configurable. You should be able to connect to the CLI

config t

PO1 int

switchport mode trunk

switchport trunk vlan native 90

switchport trunk allowed vlan add 70,80

  • Sign up between 2 tables without correspondence with values and keep the number of rows in the first Table

    Hello Experts,

    I have a problem that is a little tricky. Requirement is if 2 columns (region and Code in the tables below) match exactly, then it is Best Fit, if one of the columns match while it is average in shape, if the two columns do not match then it's worse to adapt.

    Create Table Table1 (varchar2 (10), varchar2 (10) of the filter region, Code varchar2 (10), revenue Number (15), owner varchar2 (5));

    Table1:

    Insert into Table1 values ('Test1', 'Midwest', '0900', 3000286, 'P1')

    Insert into Table1 values ('Test1', 'Midwest', '0899', 36472323, 'P2')

    Final output

    Test1 0898 22472742 P3 Midwest 18 000 8 000 - way (because the region corresponds to only), we consider 'ALL' for the Code

    Test1 West 0901 375237423 10 000 5 000 - Best P1 (region because both Code Matches)

    In the final result, we should have row count equal to Table1, and as soon as there's game (best first, then middle, then the worst), then if is once again, that we should ignore.

    There are other columns in the tables as well.

  • No communication between the Bluetooth SD - BT2 and PocketPC SD card

    I use an SD - BT2 (PA3271U) card in a Microsoft Pocket PC (also referred to as 'Microsoft PocketPC 2003') 4.20.00. I use the latest driver Toshiba 5.01 C and the card is recognized by the Pocket PC (Medion MD 95450 / MDPPC 150). I can connect to my mobile phone and GPRS connection is accumulation with no problems.

    But later at this point in time, the connection is established but dead... no connection to anyone. It seems that the communication between the Pocket PC and the card SD - BT2 is broken on the software side.

    Anyone have an idea (or a working driver) for this problem?

    Thanks in advance

    Hello

    Have you tried to reinstall the drivers or software for SD - BT2?
    In my opinion, you should check this option.

  • Best method of communication between the Application LV

    Hello together,

    I'm looking for the best way of communication between two Applications LabVIEW. As VI is clear, I can use a queue or a global variable and so on.

    But what is the best, when I compile the screw later for DLLs or Applications. So far, we always use the TCP/IP Protocol, but I think that there must be a better way instead.

    So if someone has an idea - he is welcome.

    Thanks in advance

    What I don't like with TCP/IP you still need a second thread (looped) who manages the TCP/IP communication. I thought that there must be an easier way.

    I also thought that shared variables are always limited to a single application. Thanks for the ideas...

    This second loop is a loop that YOU control. If you go with shared variables you are a slave to what they can or cannot do. In addition, they work over TCP/IP is not out of the picture.

  • Need help configuration IOS IPsec to enable communication between the VPN client

    Hi, I need help with the configuration of IPsec VPN router 2811. I want to allow communication between VPN clients, is that possible? I know that ASA, you can do this by using the command "permit same-security-traffic intra-interface".

    The fact is that each Client IP communicator installed, but when they tried to call each other, he failed. I guess that's because the connectivity between them is not permitted because of the VPN connection.

  • Linking rising switch config - Communication between them

    I'll install UCS with two Catalyst switches (3560 and 3750G). Make a channel of port pair-bond between them? It is a requirement for communication in the workplace?

    To connect the port-channel coming from the FIs to each of two switches? Or I can cable two links to the same uplink switch?

    Plase answer quickly because I am short on time...

    Post edited by: Atle Dale

    Hi Atle,

    Yes we need a l2 of common platforms for VLAN set them on the UCS, as the two FI create two different fabrics (A & B) and all traffic on the blade on B A and vice versa should be settled by the switches upstream. If you do not have a common upper the 3560 and 3750 the then you need to have a link between the two switches. Make sure that enable the VLAN (set on ucs and others if necessary) on these ports but also to ensure that the protocols spanning-tree does not block the.

    I'm not very sure of your second question, but on what I understand:

    (1) If you have several links will even pass his favorite to put in a purchase order

    (2) given that these switches are different and not in a VSS, you need seprate in. for each switch.

    I hope this helps!

  • Encrypted L3 Communications between the TOWER and WLC?

    Hi all

    I work with a client who wants to put the towers away to their WLC (a 4402). The problem is that communications between the TOWER and WLC must be secured, even through their private Wan! I have a few questions that result, if someone is able to help you;

    1. I can't know if and what method of encryption is (is it AES etc.?) used on connections between towers and the WLC and what are the steps?

      1. The terminology can be a problem here, it's not a wireless mesh, just classic LAP for WLC
    2. EXTENSIVE customer network is already encrypted (IPSec VPN via VPLS) in parts - what is the consequence of execution of AP<-->WLC with end to end (if possible) on a network encryption EXTENDED with IPSec, i.e. double encryption?

    Strange but true - pointers will be greatly appreciated... Phil.C

    With a controller of the 4400 series, the control traffic between the AP and the regulator is already encrypted AES.  The user traffic is not encrypted.  If you use a 5508 controller all traffic between the AP and the controller is encrypted AES.

    For what is running the traffic through a VPN, it should work.  The issue I see with this is with the MTU in general.  The controller will drop all packets with a payload of less than 32bytes data.  According to the MTU over the VPN I've seen packets getting fragmented and it is a question.  If you use one of the versions CAPWAP (5.2 or newer) discovery dynamic MTU is part of the Protocol and this MTU problem does not really exist.

  • Several VLANS between 2 SG300-10

    Hi all

    I have 2 switches SG300-10, and I need two VLANs, one for the internal network and the other for WiFi AP.

    I need ports 1-> 4 on both switches in order to be part of VLAN 1 and 5-2 8 > VLAN. and a 10 to the 2nd switch uplink port.

    How to configure the VLAN and the interface mode VLAN?

    1-> 4 vlan 10 port, port 5-> 8 vlan 20 and vlan port 10 10, 20 and 1? (assuming I have have VLAN 10 and 20 and 1 by default)

    Ports 1-> 8 General mode and trunk of 10 port mode?

    Thank you!

    Hi Adrien, the first question is, what is your router?

    To answer your question. Single host connection ports can be configured as any mode of port, but coelio is preferential. Links of connection between switches can be trunk or general with vlan 1 UNTAG, vlan 10 tag, tag vlan 20.

    Cli command would look like this

    config t

    Hey katycomputersystems,

    Could you give us a quick screenshot of your vSwitch / Port groups.

    Of the IP information you should be able to ping to each of the systems if they are on the same vSwitch / Portgroup / VLAN.

    Try this

    vSwitch0

    VM Network - Port Group - VLAN 110 - physical Nic don't matter we will keep all the VMS on this port group

    Configure all your VMS on the port network of VM group.  As long as all the VM living on the same port group vlan and vSwitch traffic should never leave this vSwitch and each VM must be able to communicate with each other.  If not you can always ping each other take off the VLAN and try again.  Make sure also that you have no firewall or tables ip enabled on the operating systems that could prevent communication.

    Let us know how it goes
