• IPS Inline Mode Interface - you can use a port channel?

  Hello

  I am trying to determine if you have a 2-gig Layer 3 Port channel through a 4260 IPS appliance. See the attached diagram. Is this possible?

  The customer, I work with would prefer not to enter this cost equal to Port-Channel 1 gig of links (I don't think that there is a difference in performance...) However, I think that if they want the device inline, as the diagram shows - they will have to break the port-channel. Is this a correct assumption?

  Thank you

  Asymmetric traffic will prevent the sensor works best, he is capable. There is a configuration that can be done to allow the detector deployed in an asymmetrical environment, BUT it can affect the ability of the sensor to detect attacks, allows through evasions which would have been prevented and will not affect general performance of the sensor.

  If running in unbalanced mode should be avoided if possible. BT in cases where it cannot then the sensor always allows with degraded functionality.

  Traffic spikes above what the sensor can manipulate at will cause ignored packets. There is no help for too much traffic.

  The relief you talk I guess is the bypass function. The bypass feature does not affect during the subscription of the sensor. The bypass feature will only kick if the analytical engine crashes due to a bug.

• IDSM2 in inline mode

  Hi all

  There are 2 VLANS configured in the switch of 7600 namely 200 and 300. In order to make the switch to pass these traffic vlan by JOINT (IPS inline mode), the following was configured.intrusion - detection module 2 ports data 1 trunk allowed - vlan 200 300. Apart from that, are there any requirements for the same thing. The IOS in the 7600 switch is 12.2 (18) SXF4.

  Thanking you

  You can have up to 255 pairs of vlan on Gig0/7 (date-port 1) and a 255 vlan pairs on concert 0/8 (data-port 2).

  But be aware that with version 5.0/5.1 on JOINT 2 JOINT-2 will deal with all these pairs as if they were on the same network. This can lead to confusion on the sensor if the packets are routed and run through 2 or more pairs of vlan inline.

  So if you are going to deploy in situations where routing could cause packets go through more than one pair of vlan inline then I recommend you to run the IPS version 6.0.

  IPS 6.0 can support up to 4 virtual devices. You can have a different configuration of the peg and filter in each virtual sensor.

  If a single deployment of 4 pairs of vlan online you can place a pair of vlan inline in each of the 4 virtual sensors.

  If you deployed more than 4 virtual probe, there was also an additional feature added to IPS 6.0 help manipulate it.

  You must set the Session TCP tracking Mode "Vlan only" or "Interface and Vlan" and say this track JOINT-2 the TCP Sessions only by pair of vlan inline and avoid the problem with 5.0/5.1.

  Pair Interface InLine mode is very similar to the pair of Vlan InLine. It will pair 2 VLANS.

  The difference is in how to obtain VLAN paired.

  Mode Inline Interface pair you would 0/7 and 8/0 (data port 1 and 2) to access the ports. Each port would be for just a single vlan. Place you 0/7 on a vlan of the pair and place of 0/8 on the second VLAN of the pair. The JOINT-2 would then monitor the traffic between the 2 VLAN just as it does InLine Vlan pair mode. But instead of passed back and forth on 2 VLAN of a single trunk port, they went back between the 2 access ports.

  Since it's access ports, you are limited to only one set of VLANS when you InLine Interface pair mode. While InLine Vlan pair gives you up to 510 vlan pairs.

  So I do not recommend using InLine Interface on JOINT-2 pair Mode.

  FYI: even if it has an advantage when running on a device. And the device can connect between 2 switches (a JOINT-2 can not because it is inside the switch). In this respect between the 2 switches trunk can carry 4094 VLANS. So place a device pair InLine INterface mode between 2 switches in a trunk port has some advantages.

• Development of probe pair interface inline mode

  I've never set up a probe pair interface inline mode, and I had a few questions about this

  It is my understanding that traffic from a virtual local network would be passed to the other through the probe (and then you implement your strategies passed).

  But then, how would you set up the SPAN or capture ACLs on the side of switching? A session of the monitor will put a port in disabled mode (even though I think you can use the session monitor x destination penetration to allow traffic of it).

  Or you want to use the

  Capture switchport

  order with FSPAN on both interfaces?

  Any advice would be great

  Hello

  For inline-pair configuration should be something like this

  Assuming that 1/1 and 1/2 switchport. Port Gig0/0 and 0/1 Gig IPS

  1/1 and Gig0/0 must be in one vlan, say 800.

  1/2 and Gig0/1 should be another vlan, say 810.

  switchport config:

  1/1

  switchport

  switchport access vlan 800

  switchport mode access

  1/2

  switchport

  switchport access vlan 810

  switchport mode access

  All traffic vlan 800 is sent to the port in vlan 810 and vice versa after inspection.

• IPS inline & port interface port trunk Switch

  Hello

  Is it possible to configure the IP addresses as the topology below? SW1 and SW2 SPI connection ports is in trunk mode. I would like to configure the IPS in inline mode pairing interface. (not the vlan pairing mode)

  SW1 - IPS - SW2

  Kind regards.

  Yes, this method is fully supported.

  If you want to control all the VLANS with a single virtual sensor, then assign the pair inline interface to the virtual sensor.

  If you want to monitor the VLANS with different virtual sensors, we support groups vlan on this pair of inline interface.

  Do not confuse "inline-pair of vlan" with the "groups of vlan inline on a pair of inline interface.

  The "pair of vlan inline" will pair 2 VLANS on the same interface. When a package arrives in the sensor it will be sent back the same interface with its header vlan has changed.

  The "groups of vlan" on a pair of inline interface don't change headers for VLANs.

  They are only used for virtual local networks, so that the Group of VLAN can then be assigned to a specific virtual sensor.

  You could then take a group of VLANs for your office network employees and assign them to vs0 and take a second group of VLAN for your DMZ and assign them to vs1.

  You can place a vlan unique within each vlan, or you can place several VLANs within each group vlan.

  But it only made sense to have 4 groups of vlan, because you have only 4 virtual sensors on most devices (a bit like the 4215 have 1 virutal sensor so you can make groups of vlan on the 4215).

  I also recommend that you change your virtual sensor and set the Inline TCP Session tracking mode on "Interface and Vlan. In this way the sensor will separately monitor connections on each vlan. This is necessary if a router can route traffic between several VLANs. Without this setting, the sensor will become confused if it sees the same connection of multiple VLANs.

• IPS Inline vlan pair

  Hello

  I want to set up the pair of vlan IPS inline for DMZ area, I have been through the guide of the user for pair of vlan IPS 7.0 heading inline, as I saw the pair configuration example of vlan inline, but it is not unclear to me

  Please take a look at the attached and pls explain the flow of traffic, the server goes to internet if we create a pair of vlan.

  Each default gateway server is firewall DMZ ASA interface.

  Thank you

  You are right.

  Traffic runs just like that. All servers will be on VLAN 2 from the switch and the ASA on the VLAN 3 all connected to the same switch. The IPS will be also connected to these same switches. A single interface to the IPS will be be connected to a trunk port on this switch with two VLANs allowed on the trunk and the pair VLAN configured on the IPS.

  You are right.

  BTW. Yesterday I saw someone on a study group request the same thing as you.

  I understand how to configure the switch Catalyst 6500 so that the monitoring of ports are access ports in two VLAN separate operation online.

  Note that the 6500 host is running native SXE IOS 12.2 (18).

  Thanks for any help.

  A transparent firewall is a pretty good comparison.

  Say you have vlan 10 with 100 PCs and 1 router for the network.

  If you want to apply a transparent firewall on this vlan you can put not just the Firewall interface on vlan 10. Nothing would go through the firewall.

  Instead, you need to create a new vlan, say 1010. Now you place the Firewall interface on vlan 10 and the other on the vlan 1010. Nothing is still going through the firewall. So now move you that router from vlan 10 to vlan 1010. Everything you do is to change the vlan, IP address and the mask of the router remain the same.

  The firewall transparent bridge vlan 10 and vlan 1010. The SCP on the vlan 10 ae is able to communicate and through the router, but must go through the transparent firewall to do.

  The firewall is transparent because there no IP Route between 2 VLANS, instead, the same IP subnet is on the VLAN and the transparent firewall ensuring the beidges between the 2 VLANS.

  The transparent firewall can do firewall between the SCP on the vlan 10 and the router on vlan 1010. But PC has vlan 10 talks for PC B on vlan 10, then the transparent firewall does not see and cannot block this traffic.

  An InLine sensor is very similar to the transparent firewall and will fill between the 2 VLANS. And similarly an InLine sensor is able to monitor InLine between PCs traffic on vlan 10 and the router on vlan 1010, but will not be able to monitor the traffic between 2 PCs on vlan 10.

  Now the PC on the other vlan and the router on a virtual LAN is a classic deployment for the sensors online, but your VLAN need not be divided in this way. You can choose to place some servers in one vlan and desktop to another vlan. You subdivide them VLAN to whatever the logical method for your deployment.

  Now for the surveillance of several VLANs the same principle still applies. You can't control traffic between machines on the same vlan. So for each the VLAN that you want to analyze, you will need to create a new vlan and divide the machines between the 2 VLANS.

  In your case with Native IOS, you are limited to only 1 pair of VLAN for InLine followed, but your desired deployment would require 20 pairs of vlan.

  The IPS 5.1 software now has the ability to manage the 20 pairs, but the native IOS software doesn't have the ability to send the 40 VLAN (20 pairs) to the JOINT-2.

  Changes in native IOS are in testing right now, but I have not heard a release date for these changes.

  Now cat BONES has already made these changes. So here is a breakdown of basic of what you could do in the BONE of cat and you can use to prepare for a deployment native IOS when it came out.

  For VLAN 10-20 and 300-310, you want monitored, you will need to break each of those VLANs in VLAN 2.

  Let's say that keep us it simple and add 500 to each vlan in order to create the new VLAN for each pair.

  Therefore, the following pairs:

  10/510, 511/11, 12/512, etc...

  300/800, 801/301, 302/802, etc...

  You configure the port to probe trunk all 40 VLAN:

  set the trunk 5/7 10-20 300-310 510-520 800-810

  (And then clear all other vlans off this trunk to clean things up)

  In the configuration of JOINT-2 create the 20 pairs of vlan inline on interface GigabitEthernet0/7

  NW on each of VLAN original 20 leave the default router for each LAN virtual vlan original to the vlan 500 +.

  At this point, you should be good to go. The JOINT-2 will not track traffic that remains inside each of the 20 VLAN original, but would monitor the traffic is routed in and out of each of the 20 VLAN.

  Due to a bug of switch, you may need to have an extra PC moved to the same vlan as the router if the switch/MSFC is used as the router and that you deploy with a JOINT-2.

• RDS licensing mode not configured the server 2012

  Everyone gets it on a 2012r2 RDS Server.

  I installed vWorkspace ' Terminal Server / RD Session Host role ' and turned on the 'Remote Desktop Session Host' feature on the RDS Server and when I connect to the RDS Server, I get a little popup saying right down

  Remote Desktop services "remote Desktop licensing mode is not configured" will stop working in 106 days.

  Any ideas...

  Hi Dan,.

  A RDS 2012r2 will require a remote office 2012 with 2012 cals installed remote desktop license server to handle licensing.

  You have a remote office 2012 configured license server in your environment or is it 2008? If not, you will need to create one, but it can be used to service existing if you want to consolidate everything on a single server, the RDS 2008 servers.

  Without a configured license server, it will return to the period of 120 days, you get as standard with a host of the session.

  Okay, I was not quite correct in my first post.

  These modules - modules only available for corresponding models of ASA.

  They all can act as IPS (inline mode) or IDS ("Promiscuous" mode), depending on how you configure your policies.

  When acting as IPS, ASA redirects all traffic through the module, then all the traffic is inspected and can be dropped inline if a signature is triggered.

  When she acts as an ID, ASA a few exemplary traffic is the module for inspection, but the actual traffic is not affected by the module, as it's not inline in this case.

  In addition, these modules can be both comdination. That is part of the traffic can be inspected "inline", when some other (more sensitive) traffic can be inspected in promiscuous mode.

  To better understand, familiarize themselves with this link:

  http://www.Cisco.com/en/us/docs/security/ASA/asa84/configuration/guide/modules_ips.html

• Difference between line and liabilities of ips mode

  Hi I'm new to ips. I got a 4215 sensor ips who says she can define control interfaces it is in passive mode, in which it can read packets directed to it by a switch. now since it is an ips when he reads a packet that triggers an alarm and action game goes to zero it will require a pix or a router to block traffic from the attcker or it may hang on its own since it a FPS. I'm not sure about that. can u pls guide me on this. At latest

  concerning

  Assane

  Hi... the main difference is that Supreme or passive mode provides reactive protection. It can be configured to reset the connection to the attacker, IP blocking, and registration of intellectual property, but it cannot stop the initial attack on the objectives. The reason is that packets which he controls have been copied and transmitted by sessions SPAN or promiscuosly listening to traffic on a segment.

  When the sensor is on inline mode, traffic must pass through the interfaces of the probe (pair). Traffic is inspected, tested against the signatures and then if OK, then transmitted to the destination. This approach offers preventive protection because the sensor can stop an attack BEFORE it reaches the target which is something that IDS (passive sensors) can not do

  In summary, I suggest you try to use your sensor in inline mode... It offers not only the same perfect for ID but additional protection against attacks.

  I hope that helps... Please note this!

• IDSM2 on the inline 6500 IOS mode support?

  Hello

  I have a JOINT-2 running IPS5.1 (1 d) (recently updated to 4.x) software that sits on a 6500 IOS.

  The IPS Device Manager shows gi0/7 and gi0/8 as well in Promiscuous mode. There is no option to change the inline mode and pair them up.

  Is it so that JOINT-2 currently supports only Promiscuous mode?

  If so, this module is always as IDS despite the execution of IPS5.1. Is it not? What is the advantage that I get after upgrade from 4.x to 5.1?

  -Vasanth

  There are 2 pieces of the puzzle.

  There is the JOINT-2 version and it takes in charge, but also the native IOS of Cat 6 K version and that it supports.

  Supports the v5.1 (1 d) JOINT-2

  (a) promiscuous mode.

  (b) mode InLine Interface pair (2 interfaces are matched to online tracking) and also

  (c) pair online mode of Vlan (2 VLANS on a single interface is matched for online tracking, you will also see it called inline-on-a-stick)

  But for these features to be used, the code switch must also support the configuration on the side of the switch of the JOINT-2 for each of these 3 features.

  Native versions of IOS prior to 12.2 (18) SXE will only support the Promiscuous on JOINT-2 mode.

  12.2 (18) SXE and later versions support Interface InLine mode on JOINT-2 pair.

  No native IOS version does currently support InLine Vlan pair on JOINT-2 mode (a new versions native IOS with this support is currently in development).

  For inlining (IPS), you need to run a Native IOS version 12.2 (18) SXE and later and on the JOINT-2 run IPS versions 5.1 (or even older 5.0).

  (NOTE: Cat OS 8.5 (1) takes in charge the 3 modes of JOINT-2.) Therefore, if you use cat instead of the native IOS OS, then run version 8.5 (1) to have access to all the features of IPS 5.1 (1) on the JOINT-2)

  If you run a Native IOS version prior to 12.2 (18) SXE and the JOINT-2 then it can run in "Promiscuous" mode even if 5.1 (1) is responsible for the JOINT-2.

  However, even in "Promiscuous" mode the IPS 5.1 (1) software has a few advantages.

  There are several engines and engine parameters are only supported in version 5.1 and not the version 4.0. (So there are several signatures that are either one) not yet created for sensors 4.x, or b) signature 4.x is not as precise as the signature of 5.x in new engines.

  (These new engines are proved invaluable in writing signatures to detect some of the new attacks that came out last year).

  There are of course other benefits:

  For example:

  (1) risk of note to best aid priority to alerts.

  (2) fitlering more flexible mechanism for alerts that allows individual actions of fitlering

  The 2 features above are only 2 of the new features that have been added in 5.0 and 5.1 that apply both of promiscuity and online modes.

  IPS inline help

  You encounter a bug in the IDM.

  IDM is incorrectly assuming that the interface is in Promiscuous and promiscuity.

  The sensor itself is considered just an interface monitored rather than online or promiscuity. Each package will have a header attached by the ASA that determines whether or not the packet should be monitored inline or promiscuity.

  This is fixed in IDM then she calls it just a substantive interface basket instead of incorrectly assume that it's an interface of promiscuity.

• Mode Inline JOINT-2

  Hello

  I work with the JOINT-2, we have Cisco 6509 with CSM and FWSM, we plan JOINT-2 in Inline mode and now I want to track the traffic that arrives through Interface from outside the context of FW (which is nothing but a VLAN A, B VLAN, Vlan C. on MSFC)

  Data flow: JOINT - ISP RTR - internal RTR - FWSM - MSFC CSM.

  JOINT version is 5.1 (4) S257.0,.

  It will support only two VLANS (IN and OUT) on the access mode.

  My problem is that I don't know how to analyze the traffic of 3 numbers of VLANS (A, B, C).

  Cisco 6509 - Version 12.2 (18) SXF7,.

  You can use the mode to pair for the VLAN inline to monitor traffic entering on VLAN specific. For example

  You have VLAN 100 200 and 300 on MSFC that you want to watch inline.

  You must configure the VLAN 101 201 and 301 (L2 only) and send the VLAN 100-101 200-201 300-301 to JOINT-2.

  You then create pairs VLAN on JOINT-2 module as below

  1 pair of VLAN 100-101-1

  2 pair of VLAN 200-201-2

  3 - VLAN 300-301 - pair 3

  Then set over three pairs of virtual sensor and will monitor this traffic for online operation.

  Inline VLAN pair mode is based on VLANs, so it doesn't really matter if them VLANS are behind or front of the FWSM.

  See you soon,.
