• The interface VLAN ACL of inbound traffic?

  Hi, I may be over thinking this, but I have an ACL that is applied when entering an interface vlan. I have a line to allow udp any any newspaper which is temporary. I see hits, but the source ip address is outside the network to the ip address of the destination interface vlan. I expect to see ip source addresses only in the range of ip addresses of 192.168.1.128/25. What do you think? Thank you

  Interface vlan 100

  Hello

  That looks like to me WINS navigation, a response packet.

  And as MS navigation works at level 2, it sends a response to the IP of the router where he sees demand for travel coming - maybe your customers have a configured WINS server address?

  Do not forget
  allow udp any any newspaper

  will match ANY ip src, not only your local subnet and is why your journal entries show the traffic in both directions.

• F10 4820 t - pulsations on the interface vlan

  Hello everyone

  Using Force10 S4820T on 9.6

  Rate limits can be applied to the physical interfaces only? and if yes how can I do to fix a speed limit on an interface vlan? Policy-map?

  Thanks in advance

  Based on the information contained in the user guide, it seems that it cannot apply to the physical interface.

• How to view associated with an interface VLAN IP address?

  I have a 6224 with some VLANs set up. I have addresses assigned to most of VLANs (i.e. "configuration, interfaces, vlan 20, ip 192.168.20.254 address '). I can't seem to find a way to have the switch shows that vlan interfaces have this ip assigned, either the CLI or from the web interface. It does not help that I don't think that the web interface even exposes settings for this at all.

  Thank you

• Assign IP address to the Interface VLAN of Web Admin?

  It is a simple question, I can't find can in the web config page to assign an IP to an interface vlan.

  Example: I create a vlan 40 and assign ip 192.168.40.254/24 to it, I can accomplish this with the CLI with 'config; interface vlan 40; "192.168.40.254 IP address 255.255.255.0" but it does not seem to exist in the web interface!

• X interface VLAN 4451

  I try to configure interfaces VLAN on a 4451 X and problem. I can configure subinterfaces, but I want to set up a real interface VLAN like this:

  B12_3925 (config) #int vlan 11
  * Jan 11 21:17:20: % LINEPROTO-5-UPDOWN: Line protocol on the Interface Vlan11, change of State down
  B12_3925(Config-if) #IP add 192.168.100.1 255.255.255.0

  Am I missing something? This should be very simple.

  Thank you

  Hello

  4451-X is a router, so, working with the VLAN is different to the switches. Creating a interface Vlan would make sense only if you had a switching module installed in this router and had some of its interfaces configured as switchports in the VLAN individual. Otherwise, the only way to work with the VLAN attached to interfaces routed to this router is to create some subinterfaces.

  Keep in mind: a router can have several routed interfaces and each of them can put an end to an independent set of VLANS. To a router, simply saying 'VLAN 11' doesn't mean anything, because this VLAN can be used on several routed ports and their subinterfaces. That's why the style interface Vlan is not used with routers without changing of modules installed because it is ambiguous.

  Welcome to ask for more!

• SG300/SG500 remove interface vlan

  Hello!

  The question is the following:

  I add a VLAN interface to test IP connectivity to this vlan by adding an IP address for this interface vlan and ping on a host.

  for example
  interface vlan 5
  192.168.0.251 IP address 255.255.255.0

  Then I can remove the ip address "without ip address', but I can't delete the ' interface vlan 5".»

  Even when I delete the vlan itself of the database for vlan. There is no command "no interface vlan. I can only stop the interface vlan.

  If anyone knows how to remove the interface vlan switches SG300/SG500 cli.

  Thanks, Woeger

  Hello

  I tried just that with my switch from laboratory here.

  I created VLAN 10 and he has given an IP address.

  Then I did a no ip address on the interface VLAN and then not a vlan 10.

  At this stage there is no interface THAT VLAN 10 in my config running or when I do a show ip interface.

  So remove the VLAN has done actually remove the interface for me, brings me to my question.

  What version of the bootcode/firmware do you currently use?  Maybe this problem has been fixed, because I am running 1.3.7.18 firmware with 1.3.7.01 code to boot.

  If you are on a low moving forward and put to date, don't forget to upgrade the boot thus code, it is necessary for new versions of firmware.

  Hope that help, but if not just let me know and we can take another look,

• SG300-20 - configure DHCP on the interface VLAN

  I have read the different partners of the discussions on the SG300 and SG500 going on regarding the high setting of VLAN and DHCP on VIRTUAL networks.  For some reason, I could not get even this simple task to work.

  First thing I did was update my version firmware and boot as follows:

  SW version 1.3.7.18 (date of 12 January 2014 time 18:02:59)

  Start the 1.3.5.06 version (dated 21 July 2013 times 15:12:10)

  HW version V02

  When I rebooted the SG300 after the SW/Boot updates the boot configuration has been crushed and I had to configure my switch from scratch.  The intention is to have two VIRTUAL networks:

  VLAN 1: all the devices, servers, etc.

  VLAN 2: subnet basis which distributes DHCP addresses

  The SG300-20 is connected to a router Asus RT-AC66U on the 192.168.1.x subnet and provides access to the internal network and WiFi access (IP address of the router is 192.168.1.1 and the default gateway).  Everything works without any problem.  So my task is simply to create 2 VLANS on 192.168.2.x subnet and use DHCP to assign addresses.  I spent many hours on it and I still can't get it to work.  When I connect a laptop to the port (GI8) assigned to 2 VLANS, I end up finding a few wobbly 169.254.x.x address.  I definitely thought something would not 'easy' that hard to set up, but apparently I was wrong.

  The SG300 is running in mode L3 as shown in my running-config below.

  Someone gets to see something which could prevent my client from the laptop to receive the interface VLAN 2 DHCP IP addresses that are not on the 192.168.2.x subnet?

  Any ideas / suggestions would be greatly appreciated!

• 3rd interface VLAN does not add properly

  Hello

  I have some difficulty with a switch 300 series running in mode of L3. I created two VLANS each with an interface IP that work well without any problems. The problem I have is when adding a third interface VLAN and IP - for some reason the switch seems not add the subnet in its routing as a directly connected route table.

  The first and second VLAN add correctly. It seems to be the third. I have factory default, the switch and still the same. Version is 1.1.2.0.

  The Setup is as follows:

  VLAN1 - 10.20.2.253/24

  VLAN2 - 192.168.2.253/24

  VLAN3 - 192.168.3.253/24

  Craig

  Hi Craig,.

  I don't think you're doing anything wrong.

  The command line shows that this IP for VLAN3 interface is not connected, or at least nothing is connected physically VLAN3.

  Connect a PC VLAN3 and see if the interface road happens.

  I guess just that nothing is plugged physically vlan3.

• Maximum virtual interfaces (VLANS) FWSM latest version

  Hello

  Please someone (perhaps cisco) can tell me for the FWSM for the latest 3.x version that corresponds to the maximum number of virtual interfaces (VLANS)?

  Best regards.

  It depends on the firewall mode, but I think that most of the time, the limit of vlan is related to the routed mode.

  Refer to this VLAN 3.1 FWSM features/limit:

• traffic Windows 7 not out on the interface of traffic as it is assumed

  Hi experts

  I got this company of Win7. I want to install two network interfaces on it. A network interface will be for the management of the machine itself. and another interface for application traffic. I had an application that I run and which consumes a lot of bandwidth to the point that if I put everything on an interface I could lose the RDP connection.

  Also, I have set up my IP of mgmt interface. and it works. I can RDP into it. But when I configure the 2nd interface with its IP address, the auto road which becomes forces added traffic to pass by my mgmt interface/IP, which is not what I want.

  These two survey periods are two different subnets and they go to different switches. I did a simple sketch of my installation below to show what I'm trying to accomplish.

  Under linux, I would just like to add a static route and who takes care of this, but how do I do that on Windows?

  I follow this guide but still have the same problem:

• creating groups of VLAN - traffic disruption

  I asked this question of TAC and got a vague response, so I was going to post here to see if someone had actually done this and what were their results.

  We have a fairly basic config of UCS currently, there is a port on each fabric channel and our uplinks can take care of all our VLAN so all VLAN can use all uplinks.

  We will soon add a new channel of port that will only serve the VLAN specific (trafifc for the external VCC of our Nexus 7 k). So we will now have a disjoint network layer 2, where VLAN 1xx require port-channel 1 and VLAN 4xx can only use the port-channel 2.

  I have read all Cisco docs and it seems rather simple to deal with groups VLAN so that we make sure VLANS only try to use correct rising/port-channel binding, however our concern is moving all our VLAN existing in a group VLAN and the final outcome of this. I ran this by TAC and they said that there could be a "brief traffic disruption" when we apply this config.

  It gives me some anxiety b/c we are talking about all our ESXi hosts and each VM on these hosts (500 +). However it may be brief, that could be a problem if all of a sudden everything is unable to speak.

  Someone had an existing config that they moved to a configuration group VLAN and what has been your experience? It disrupt all traffic?

  We have not added the new port-channel, so everything we do now is entering a group of our existing VLANs and by assigning them to the existing port-channel.

  Any comments or thoughts would be appreciated

  We did just that. We moved in four areas separated into four groups of clan. We have created our groups and then all the VLAN for this corresponding uplink at the same time. We didn't see any packet loss or impact to end users.

  We have a facility of similar size. About 20 blades, ESXi server and windows, behind the pair of FIs. About 400 machines behind that. The movement is quick and easy.

  Previously, we were using the uplink of LAN Manager. I found it a bit heavy. Clan group works much easier in my opinion.

  Plan a window of maintenance, to be careful, but my experience of 25 VLAN moving through four interfaces different disjoint layer 2, we have not had any problems.
