• 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!

• 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!

  Thank you

• 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

  IP 192.168.1.132 255.255.255.128

  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.

• Lockout Ganymede, define the interface VLAN bad

  Hello

  In the middle of application and test the new configs GANYMEDE, I put the t 'GANYMEDE SOURCE INTERFACE IP' to the VLAN evil. My mistake and fortunately, I tested on a switch that is not really used. So I tell myself no case submission, I'll disconnect the trunk and move the console with the user name, with my understanding that if no RADIUS server is available, the local user name would be used. Well the name of username/password combo is not correct or the theory of "not being able to communicate with radius server, so use the local username" is not correct.

  Anyway, anyone have any ideas? Perhaps a password recovery can change the username password and fix VLAN?

  Thanks for your help...

  Hello

  If you are not able to access the switch, simply do a recovery of password for the switch. you would be able to access the switch and change the configuration.

  It is based on the orders of AAA configuration for authentication if you gave Ganymede then local authentication if the aaa is not accessible...

  Thank you

• ASA 5540 - cannot ping inside the interface

  Hi all. We have recently upgraded PIX to ASA5540 and we saw a strange thing going. In a Word, we can ping the inside interface of the ASA from any beach on our 6500 network (which is connected directly behind the ASA on the inside), but one where our monitoring tools are placed. Inside there is an ACL that allows all of our core networks, but it does not help that the interface is really strange.

  In the ASDM, I see messages like this:

  ID ICMP echo request: 2004 x.x.x.x y.y.y.y on the inside interface to. I don't think that's the problem, but I could be wrong.

  This is also the configuration of the interface VLAN VIRTUAL local area network from which we cannot ping inside the interface we can ping to and since this VLAN and machines without problem. The only problem is ping the inside interface of the ASA.

  interface Vlanx

• 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,

• All traffic Vlan to the Interface of the Proxy Server

  Hello!

  I need little help to route all the traffic on VLAN to the proxy server.

  I have different VLANS on switches L2 200-26 and by 300-28-L3 for routing.

  I have already created VLANs and able to rout them, but facing problem for routing traffic to the interface proxy for internet access.

  I have different VLAN for example Vlan 10, 10.10.10.0/24 sales, Vlan20 10.10.20.0/24 Marketing. I have trunk between switches interfaces and default 1U is the same on all switches.

  My proxy server has two NICs, one is connected to a dsl modem and other one to the switch port that uses the IP 192.168.0.2 to default vlan1.

  I am able to surf the internet using vlan1 but not on ther VLAN.

  I put the route defaults to the switch of 192.168.0.2, but don't not routing for internet to another VLAN.

  Thank you

  Hello

  To answer your questions:

  1. I have to update the following files?

  https://software.Cisco.com/download/release.html?mdfid=283019617&release...

  Yes, please let me know what firmware and boot code, that you have right now and I'll tell you what is the best way for you to upgrade because you shouldn't go straight to the latest firmware unless you run already 1.3.5.58 or later version.

  2. it supports to 8 dhcp pools. I have swimming pools, but I have more than 8 VLAN. I put all the settings, works very well.

  You are right and I forgot to mention the limitation of only 8 DHCP pools, I'm sorry. That being said, make sure that your current DHCP server uses IP addresses assigned to each VLAN on the switch as the gateway by default for the VLAN respective.

  3 for the Proxy Server, I need to find a way to point back roads of VLAN to vlan mapping static address on the switch. I'm confused in this little piece.

  I understand that this can be confusing, let me see if I can explain it a little better.

  Assuming that everything on the switch is configured according to my recommendations can

  1. you need a single, a route by default on the switch, so that when a PC is connected to one of VLAN on she tries to go online, an unknown IP address to the switch, it will send it to the Ip address of the router, because the proxy server will be able to reach this IP public, unknown to any Web site.

  2 - when the traffic is back to this Web site, it will be intended for another subnet that the proxy server is on. Suppose the answer is looking for 10.10.10.100 (subnet unknown to the proxy server), without a static route on the proxy server it say where to send this traffic, packets are simply deleted.

  3. you need to create as many static routes on the proxy server as the amount of VIRTUAL LANs, you have on your network.

  For now I know that the proxy server is 192.168.0.2 on VLAN 1 but I don't know what the IP address of the switch is on the same VLAN, it should be something on the 192.168.0.x range.

  All journeys should look like this:

  10.10.10.1 255.255.255.0 send 192.168.0.x (IP address of the switch on the VLAN 1)

  10.10.20.1 255.255.255.0 send 192.168.0.x (IP address of the switch on the VLAN 1)

  Alternatively, if all your internal VIRTUAL local networks are on the beach of 10.10.x.x then you should be able to create a single rule to summarize all the VLAN as this:

  10.10.1.1 255.255.0.0 send 192.168.0.x (IP address of the switch on the VLAN 1)

  Please let me know if it was a little clearer.

  Feel free to ask any questions.

• 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.

  Thanks for the help.

  JJ

  Hi JJ,

  If you plan doing a ping within the IP address of the interface, while the traffic is coming from any interface other than inside, you won't able to ping inside the IP address of the interface.

  This is by design, and you cannot change it by any ACL or other settings.

• Extend the L2 VLAN multi-site WAN

  Hello

  I have several sites connected over a MPLS network provider, everything works as expected, have full connectivity L3 in all these sites.

  I now need to establish layer 2 connectivity (VLAN) on the 21 sites. Ideally, I would intend to attach additional routers behind routers of THIS (don't have no access to these suppliers or PEs, but provider may re - configure BGP on the CE peer with our device) and use a port on these routers as port Lan Layer 2, but do not know which technology to use

  1. L2TPv3 comes to mind, but can L2TPv3 works in a multipoint configuration? Can I have a site as a hub and others like rays and talk through the hub? Traditional using L2TPV3 config, how do I use multiple Xconnects for the same VLAN on the same interface?
  2. Worse, I can run on (also our new routers VPLS PEs) MPLS VPLS, but seems like overkill.

  What you guys say is the most simple/more elegant solution for this puzzle?

  L2TPv3 does not support multitouch.  It can perform point to point.

  VPLS does support multitouch, but you need much more expensive kit to do.

  I have just a brainwave!  You only use the IP protocol for this network of layer 2?  If so, use LISP.  It works on the same lower end kit of Cisco.  I would like to convert your entire network to him.

  In particular, you must activate the LISP mobility.

  General information of LISP:

  http://Lisp.Cisco.com/

  An example of an extension of the continuous complex layer 2 using LISP with full redundancy.  You don't want something this complex, but it shows what you want to do, and the massive power that LISP has.

• Allow specific access through the Interfaces ASA 5510

  Hi all

  In my quest to learn Cisco IOS and devices, I need help in smoothing traffic, or access lists, allowing traffic between internal interfaces on the SAA specifically.

  I have an ASA 5510:

  WAN/LAN/DMZ ports labled E0/0 (LAN), E0/1 (WAN), E0/2 (DMZ).

  Connected to the port E0/0 is a 2811 router

  Connected to the port E0/1 is the (external) Internet

  Connected to the port E0/2 is a 2821

  (I'll add a 3745 for VOIP) port E0/3, but it has not yet happened.

  I want to allow traffic between the 2821 and the 2811 routers so that devices on the networks behind them can talk to each other.

  I've specified specific subnets between the ASA and the routers because I want to learn how to shape traffic behind routers, as well as on the ASA. So behind the routers I have different VLANS, but I'm not restrict access between them, still, at least I don't think I am. But as it is, behind the 2821 devices cannot access the DNS / DOMAIN SERVER that is located behind the 2811. Right now I have the routers DHCP power, who works there. Currently devices behind the router 2821-3560 switch cannot access the domain server, primary dns server.

  How can I set the ASA to allow traffic to flow between the two routers and their VLANS?

  Here's the configs of each device and I have also included my switch configs, incase something should be set on them. I only removed the passwords and the parts of the external IP address. I appreciate the help in which States to create and on which devices.

  I think it is best that I put the links to the files of text here.

  Thank you!

  You must remove the following statements on the two routers:
  -# ip nat inside source... overload
  -for each # ip nat inside/outside interface, if they have configured.

  Remove ads rip of the networks that are not directly connected:
  -2821: 172.16.0.0, 192.168.1.0, 199.195.xxx.0
  -2811: 199.195.xxx.0
  -ASA: 128.0.0.0

  No way should be added to the routers, since he is the one by default, put in scene to ASA.

  Check the tables of routing on routers and the ASA.

  On ASA:

  -Remove:
  object-group network # PAT - SOURCE
  # nat (indoor, outdoor) automatic interface after PAT-SOURCE dynamic source

  -create objects of the networks behind the LAN router and enable dynamic NAT:
  network object #.
  subnet
  NAT (inside, outside) dynamic interface

  -review remains NAT rules.

  -to set/adjust the lists access penetration on the interfaces. Do not forget to allow the rip on the LAN and DMZ interfaces.

  -Disable rip on the outside interface.
