• PowerConnect 3548 - change port access mode?

  I'm having a problem with our 3548 P PowerConnect switches.  I guess it's just a procedure, I'm not aware, so I hope I can get help.

  It was necessary to temporarily move several ports to general mode to add access to a VLAN individual.  Right now, I would like to remove this VLAN and only have ports of the switch in question on VLAN 1.  I get a (not unexpected) error when trying to add ports to VLAN 1 (because it is not created by the user, the default VLAN), I tried to simply remove the VLAN ports and switch back them to General.  When I do, I get the following message:

  EXX port: Port does not belong to VLAN PVID as not tagged.

  What command sequence should I return the ports to access the mode and just make sure they're on the VLAN 1?  I guess I should do something about port traffic to not tagged or delete the PVID before returning to the access mode.

  I think I fixed the problem.  If I set the VLAN existing as non-tagged, i.e.:

  "switchport vlan allowed general access Add VLAN unidentified".

  This removes the image of marking and allows me to go back to access the mode on the switchport.   Yet to get used to the command structure; Thank you for putting up with my questions.

• change in Dynamics car for access mode will disable DTP effectively?

  Hi all

  "n a switch basis spoofing attack, the attacker takes advantage of the fact that the default configuration of the way of the switch is dynamic auto.". The network attacker sets up a system to spoof himself like a switch. This theft requires that the network attacker capable of emulating 802. 1 q and DTP messages. By encouraging a switch in thinking that another switch is trying to form a trunk, an attacker can gain access to all the VLANS allowed on the trunk port. »

  My question is. East-configuration of a dynamic to access the port DTP stop auto port? Or should be still the switchport nonegotiate command to run to the port in question?

  EDIT:

  • switchport nonegotiate- prevents the interface generating DTP frames. You can only use this command when the interface switchport mode access or trunk. You must manually configure the neighboring interface such as a network interface to establish a trunk link.

  I think that it answers my question, but can someone please confirm

  Thank you and best regards

  Hi Adam, Mark,.

  Let me join you.

  As far as I know, a port set to the static access mode was disabled by default DTP. Switchport nonegotiate on a static port using access is not harmful but really does not do anything, like DTP would have been disabled in any case.

  See the following output. I have two ports, a static access a single static trunk. In the output of the show interfaces switchport , the access port said "negotiation of Trunking: Off" (which means DTC) while the trunk port reports this feature on. When I disable DTP on the trunk by using switchport nonegotiate, the trunk reported negotiating trunking as well as off, identical to what access port has had all the time:

  HQ(config)# do show run int fa0/10Building configuration...
  
  Current configuration : 58 bytes!interface FastEthernet0/10 switchport mode accessend
  
  HQ(config)# do show run int fa0/11Building configuration...

  HQ(config-if)# do show int fa0/11 switchportName: Fa0/11Switchport: EnabledAdministrative Mode: trunkOperational Mode: downAdministrative Trunking Encapsulation: dot1qNegotiation of Trunking: Off[ ... cut ... ]
  
  

  Personally, I do not believe that an access port longer listening DTP frames. Yes, it can receive (it is connected to send link partner or not these images, right?) but reject it immediately.

  Even if an intruder connects to a switch configured as an access port port it doesn't really matter because even if the neighboring interface is set to dynamic auto / desirable Dynamics / trunk it will end up as an access port.

  
  This is true but an attacker wouldn't be using an ordinary Cisco switch that is well-behaved. The attacker would use a PC and a DTP message injector tool to try to force the other port to become a trunk, regardless of what is the other port's response. Of course, if the port at the other end is a static access port, the attacker is out of luck.

• Trunk vs Access Mode

  I need clarification on a trunk port.  You still want to use trunk when you connect to another router?  I have an ISA550 and one of the LAN ports is connected to the WAN port on the router to another.  I've never dealt with this config help would be appreciated.

  A trunk is used when you have the possibility to be carrying several VLANs on a single link. If there is only a need for a single VLAN not marked between your devices, use the access mode. If you need several VLANs or predict the need for them in the immediate future, use the trunk.

• Accessibility mode

  Accessibility mode, (not handicap friendly)

  My child is a student learning support, accessibility options will not read the document to him, it simply does not respond when activated.

  I've planned to adobe to help him read his school material and came very close to buy a full version,

  Instead, we had to try to use MS Narrator, who says 'Read word' before he reads every word.

  Try to ask for help in solving the problem, I just looped around user forums.  most of those I've seen have never been answered.

  This company supports their software? or should I look for glassware.  I might have to recommend another drive to the entire district.

  Let me know if you know a solution,

  Thank you.

  The document must be marked for accessibility, otherwise it can not be read at all or it can be read in the wrong order. You can start by checking if it is marked with file > Document properties > Description.

  Adobe Acrobat (not the free Reader) has an accessibility checker: using Acrobat Pro DC accessibility checker that tells the whole story (well beyond the check mark in the properties of the Doc). I teach the layout and most of my students do not understand the importance of mark for accessibility, until we talk about.

• IO access mode

  Hi guru
  
  I have a few questions about the Access Mode in essbase
  
  How can I check the I\O Access Mode? How can I change the access mode IO buffered direct IO mode? It is advisable to use Direct i/o for retrevial mode faster as cache memory would lock for index file
  
  Any information on this would be helpful
  
  Thank you

  Here's a decent thread on the subject: understanding buffered of i/o and direct i/o

  Personally, I never use it, but it is a sample of one. It used to be very bug and I never really found a need for him.

  You can search for additional threads - it was discussed a bit.

• Switchport access removed.

  Hi all

  I have a stackable SG500 28 G POE switch. See my config below in my switch and this is corect no problem configuration.

  This port was used for iphone for vlan 20 and 440. All of a sudden just where the question arises, iphone cannot be used and I check the configuration as shown below.

  Looks like it was deleted automatically. If you have an idea why this occue it would be much appreciated.

  Hi Mohd, if the configuration is "disappear" it is probably because the intelligent ports on write your configuration that is the result likely, you have a device upstream advertising something different.

• Cannot access Mode without failure and the FBI FALSE Virus

  Somehow, I had this Fake FBI Virus that requires you to pay $200. When I load my computer it will automatically load to the top of this Page of FBI Fake me NO access to my computer. I am acutall on a different computer now and I read some info on it. I unplugged my internet cable in the hope that the safe mode might run with it is connected and without it but when I load only restarting my computer safe mode. If I load it with network or command prompt layout it doesn't load even upward. When I do normal safe mode that need me for my login password screen, then said that he stops and forced restarts taking me to the regular connection not safe mode and if I connect it will just take me to the page again.

• Device insulation only on a specific access mode FlexConnect point?

  Hello.

  We have a SSID with activated peripheral isolation.

  Now we would be able to disable the device insulation on a basis "by"AP"- given that all the points are connected mode FlexConnect.

  We are in short 7.6.120.0 OS and have APs 3500 Series (and a few 3600).

  Thanks for your response!

  F.

  Hi Flavio,

  Peripheral isolation (I assume you are referring to the P2P blocking) can be done on a per-WLAN basis and each WLAN must be unique for a WLC so that you will not be able to do this with a single WLC even with FlexConnect/AP groups.

  The only workaround/hack that I think you could do is to have an another WLC with the same SSID accommodation PSA for this area especially with the disabled blocking P2P but that only affects customers on this access point and break roaming between APs etc.

• EZVPN nem - Internet access mode

  Hello

  I have a router cisco 881 and an asa 5520 SW 8.4

  I configured EZVPN NEM mode between the router ASA and 881.  However the 881 can access network resources on the inside interface of the ASA, where it ends.  However the site using the 881 cannot access the internet.  I know that I could configure split tunnel and the site would use only the tunnel for our internal network (10.0.0.0).  However, I want this site to our ASA allows access to the internet so that the restrictions will apply to this site too.  I apologize in advance if I have not provided enough information.

  Router config 881 is lower, ASA config is too big to post, but if you tell me what exactly you want I post, I will;

  Hello

  As long as the traffic to any other network other than the network to remote sites runs through the VPN connection, then the more typical than the ASA things central may be missing are the following

  permit same-security-traffic intra-interface

  If this configuration is already currently in use can be controlled with

  See the race same-security-traffic

  The above arrangement allows the ASA transmitting a packet entering an interface through this same interface, that it came at the start. Without this parameter, it is not impossible.

  Then you will naturally NAT configurations for users of the Remote LAN connections

  If we were to use NAT Auto / network object NAT (since I don't know how you have built the base dynamic PAT to your central site ASA) configuration might look something like this

  network of the REMOTE-SITE-PAT object

  172.16.217.0 subnet 255.255.255.0

  dynamic NAT interface (outdoors, outdoor)

  The above should provide the dynamic PAT to the interface ' outside ' of the ASA central when the hosts are connected to the Internet.

  Given that the NEM Mode VPN is probably connected right now that you can test what would happen to a related Internet packet across the VPN connection (even before changing the settings above)

  entry Packet-trace out tcp 172.16.217.100 12345 8.8.8.8 80

  That should tell what happens to the content of the package. If you are missing the first order, I suggest you the output of "packet - trace" will be very short and should see a DECLINE Phase very quickly

• Local Access Mode - manual removal via WAN connection

  I would like to set up local access to some desktop computers, but want to use the option of manual control (pg 254 of the admin View 4.6 guide) I released the base image which was published on the forwarding server, but when a user try to complete the payment process they get the error "a connection to the forwarding server could not be established. Please check your network settings. They are able to see their jobs right and that it points to the base image they received via other channels of distribution (and not directly from the servers of the view)

  My security server firewall is configured to allow the ports on the JMS, JMSIR, AJP13 connection server, http, https and PCoIP but how to configure the forwarding server to adapt to configuration or are there alternatives to opening ports on the server to transfer inside the LAN of business if I want to just use it for access in local mode

  Hi Mobcdi,

  Option 1 (tunnel) description says "network traffic is routed via the view connection server or a server security if one is configured."

  Sequence - 1 is seems more correct, but with slight modifications.

  Form SS must be a SSL connection to TS, because all local traffic is routed directly between the SS and TS

  Firewall rules of back-end on Page 61 of the www. VMware.com/pdf/view-46-architecture- planning.pdf said

  "If you configure the connection to the server display to use SSL for operations in local mode and office supply, security servers using port 443 for downloads and the replication between the local mode desktops and server transfer."
