• WLC primary and secondary

  Is there a way to add controller dymanic interface using WCS and push down to the primary and secondary WLC?

  Can I use the same IP address for the dynamic interface on both controllers? Basically, this IP address use to request DHCP for clients.

  Thank you

  IP address of all dynamic interfaces must be different form each WLC. I add interfaces manually and don't use WCS.

• What is the difference between codec primary and secondary codec in cts-3000?

  Hello

  I'm a novice on telepresence. This community is only a place to resolve issues for me.

  What is the difference between codec primary and secondary codec in cts-3000?

  I know the primary function of the codec. but I don't know exactly of secondary function of codec.

  Help me please.

  Hello

  On a CTS 3000 system, you have 1 codec primary and secondary 2 codecs. Secondary codecs are responsible for the camera left and right and view the connections. They communicate the main codec via an Ethernet cable.

  Here is a guide to the installation of a CTS-3000 so that you can see the routing of cables.

• Differences in exchange rates between primary and secondary school in general ledger

  We have a little problem on our hands... we are implementing two great books with display dynamic, primary secondary and Canadian Dollar in USD.
  
  Exchange rate variances occur if for example, we consider significant operations at different points in time. We have no problem at the primary level. However, CAD to USD exchange rates are updated on a monthly basis and most likely, rates change in the month. Therefore, exchange rate differentials would happen frequently in the secondary accounts.
  
  We were asked by senior management, how these gaps would be treated by the EBS. I was wondering if you have any ideas that we are looking at events from accounting to ALS.
  
  Thank you
  
  Sanjib

  If the need was for the balance of the Canada and US dollar, you can use the option of Reporting currency instead of secondary accountant.

• WLC 4404 and high availability

  If I have 2 WLC 4404 are supported 100 Access Points for one and I installed 110 Access Point, I can you decide when a WLC down who are the 10 Access Point which must lie down?

  Thanks for your help

  fcostalunga

  Let me understand your question.

  You have two WLC and can support 100 AP. You have 110 APs. If one of the WLC must go down, how you can configure or say which 10 AP will not be able to join?

  If this is your question, here are some solutions I can think.

  1. H-HARVEST. If you enable REAP H to your AP, when one or ALL of your WLCs must go down, the AP will be able to operate as if the WLC has increased. The exception-to-the-rule is to NOT reload the AP and it should be good.

  2. you can configure, CLI only, 100 AP s primary and secondary controller. 10 AP will no config, so they will go into "limbo".

  I hope this helps.

• synchronization between the primary and standby database

  (1) making a primary database and secondly of Eve
  (2) synchronization only differential data betwwen the primary and secondary daily.
  
  
  Please help me

  Hello

  What is the physical standby?
  Do you have the chance to look over the physics of the standby database.
  You just need to apply daily archived file generated to the standby database. This can be done manually or automatically through data guard.

• function of guard of source IP and dhcp DHCP scope of exhaustion (customer parodies other customers)

  Hello world.

  A dhcp server assigns ip address based on the mac address by equipment of the customer field in the dhcp packets.

  A potential attack is when a crowd of thugs mimics different mac addresses and causes the dhcp server to assign ip addresses until no ip address is left for legitimate host.

  For example, a host with mac1 h1 is designated by the ip address of the dhcp server as:

  199.199.199.1 mac1

  DHCP server has this entry in its database.

  Using hacking tools such as Yersinia or Gobbler can create a DHCP discover messages every time that create another mac for material scope of the client to the dhcp server, thereby causing a dhcp server to assign ip addresses because they are of legitimate dhcp to dhcp server discover messages with matching each another Mac in hardware of client addresses.

  You could use dhcp snooping and it will avoid that (exhaustion of dhcp scope) and configure the switch to check if the CBC mac fits the hardware address of the client in the dhcp message. But when even we can creat spoofed discover messages where mac src in the ethernet header will match the client hardware address in dhcp discovery message. It did not always overcome the problem.

  You might say use IP source guard characteristic but it really will prevent this problem from happening?

  Let me illustrate:

  H1 - f1/1SW - DHCP server

  Let's say that we have configured dhcp snooping on sw1 and f1/1 is untrusted port.  Switch a suite dhcp binding

  199.199.199.1 mac1 vlan1 f1/1

  Then, we configure source ip guard in order to validate the mac src and src ip against the dhcp bindings. When you configure keep source ip first, it will allow dhcp only if a host can request ip address and dhcp binding can be built. After that IP keep source will validate ip or mac src src or both against the binding.depending dhcp on how configure us source ip guard.

  In our case, we have configured source ip guard in order to validate the mac src and src ip against the dhcp binding.

  A dhcp connection is already created as:

  199.199.199.1 mac1 vlan 1 f1/1

  Now, using hacking tools Yersinia or Gobbler on h1, we create our first spoofed dhcp discovery message where mac src = mac2 ethernet header and client harware address = mac2 in dhcp discovery message. As the switch is configured with the function of guard of source ip and therefore allows dhcp discover message to pass through. DHCP server after you receive the message dhcp assigns another IP from the pool. The dhcp server has now after the entries:

  199.199.199.1 mac1

  199.199.199.2 mac2.

  We continue to spoofed dhcp to craft discover messages as described above and are dhcp server keep ip address assignment until exhausts the entire pool.

  So my question is how ip source guard in conjunction with dhcp snooping doesn't stop this attack does not happen? (IE DHCP scope exhaustion)

  I really appreciate your comments.

  Thank you and have a week.

  Hi Sara,.

  Ask was quite interesting. As far as I know that whatever it is port snooping untrusted won't let your fake dhcp server.

  You can take this query in the Sub forum of experts mentioned that is specific for dhcp snooping and source of guard.

• 6248 VLAN do not receive the DHCP scope

  I created two new DHCP scopes in my windows server 2003:

  192.168.2.0 - public, and
  192.168.3.0 - VOIP.

  This DHCP server is connected to a Dell powerconnect 2708, which is connected to our new powerconnect 6248P via fiber point-to-point.

  In the new computers on network on the default 1 VLAN are correctly attributed IPs as they connect.

  I issued the following commands to the 6248 CLI:

  Enable
  Configure
  database of VLAN
  VLAN 20
  VLAN 30
  output

  Configure
  range of interface ethernet 1/1-g1/g2

  IP routing

  I also added all traffic on VLAN 20 and 30 of VLAN on ports 1/g11 (6248) and port 2 (2708). VLAN 1 access was removed from ports 1/1/g1-g6 (6248)

  Everything seems to have been set correctly, but I can't get a response from the DHCP server on all ports attached to VLAN 20. The powerconnect 2708 switch is unable to pass the baton to the server? Is it possible that something falls in the point to point?

  I would greatly appreciate any comments or suggestions, thanks!

  The 6248 has no default gateway. It wont let me put 192.168.1.1 because he does not reside in the same subnet as the 6248 (192.168.99.1)

  The 2708 has listed 192.168.1.1 as its default gateway.

  At this point, the network has too many complexities for me to unravel. I am very happy that at least I solved for DHCP when we finally migrate our server to the new location.

  Once the server is up, and the gateway/firewall are directly connected to the 6248; I will review the correct configuration of this network.

  Some advice to those who might have a similar problem: check your management VLAN. It may not be the same VLAN 1 if you plan to routing to work from VLAN 1 to nowhere else because the VLAN management cannot be routed. Also check static routing of your access point, make sure the front door has a return of the ips of your VLAN, IE: 192.168.2.0 255.255.255.0 gateway_ip

  That's all for now. Thank you to all who have contributed
