Cisco Switching/Routing :: 3560 Extend VLANs Out To Remote Access Clients
Mar 31, 2013I am not sure if what I am trying to accomplish is possible. On my internal network I have the following VLANs setup (102, 104, 106) and they map one to one to a subnet (ie: 102 = 192.168.102.0/23, 104 = 192.168.104.0/24, etc).All interVLAN routing is done on a 3560 via vlan SVI. Connected to the 3560 via a routed port is a ASA 5510. The routed port has IP 192.168.100.1 and the ASA interface on the other side of that routed port has IP 192.168.100.2. I use 802.1x on the wired network to assign users (based on their department) into a specific VLAN. I want to extend this concept to Remote VPN access. Therefore I setup multiple Group Policies (policy is applied based on an LDAP attribute) where each policy defines a different DHCP scope. This has successfully allowed me to login wtih different users who get assigned to different Group policies and they obtain the correct DHCP IP address from the internal DHCP server (ie: an engineering person logins remotely and gets an IP in 192.168.102.0 range). However the issue (and as I was planning this out I knew this would come up) is that traffic can be routed out from the VPN client to its destination but there is no return path.

Mar 16, 2013i have one SF300-24p switch where i setup some Vlans and echolife hg8245 ONT router to access internet. the diagram is the following
VLAN1 (Subnet of users) -----> Switch SF300-24p
VLAN2 (Subnet of users) -----> Switch SF300-24p
VLAN3 (HG8245) -----> Switch SF300-24p
VLAN4 (Servers) -----> Switch SF300-24p
i want to control access to internet on VLAN1 and VLAN2 (access on VLAN3), while providing access to VLAN4.My problem is in connecting to internet, i can't find a way to "route back traffic to VLANs 1 and 2 since HG8245 don't seem to provide proper static routing ON LAN interface. Maybe without resorting to changing the HG8245 router ?

Apr 16, 2012I am trying to setup VLAN's in the company I work for and I am almost there but missing the part when the internet works.I have an SG300 as a L3 Router IP 192.168.0.93.I have created VLAN20 and VLAN40 Assigned VLAN20 192.168.2.1 and VLAN40 192.168.4.1
The static routes have been created and a default router going to the Sonicwall firewall at 192.168.0.1.Port 24 is configured as Untagged VLAN1, Untagged VLAN20 and VLAN40 in trunk mode and going to the Sonicwall NSA 2400. [code]
Working to move all 192.168.0.x network off of VLAN1 and move it a management switch.I have DHCP helper on pointing to the DHCP server.Both VLAN's once the DHCP server is configured to Gateway 192.168.0.93 can get an IP from the correct subnet either 192.168.2.x or 192.168.4.x
All PC's are getting a GW IP of 192.168.2.1 pr 192.168.4.1.All test PC's on both VLAN's can ping each other and any server with the correct GW.When I try to ping google.com or open a web page and try google.com it times out.
Cisco Switching/Routing :: 3560 / Creating Extended VLans And Subinterface?
Jan 24, 2013We have a 3560 switch running IOS universalk9-mz.150-1.SE3.bin.Recently, we saw two problems with this switch:-
1. if we try to enable subinterface on any routed interface , for eg. gig1/1, it says invalid input detected. It doesnt accept encapsulation command also. Following was done to enable subinterface:
int gig1/1
no ip address
int gig1/1.2000
ip address 1.1.1.1
under the gi1/1.2000 subinterface, it doesnt present the option of ip address.
2. we created a layer 2 vlan 2000 like: vlan 2000 When we do an exit after creating this vlan , it gives following error:-
%SW_VLAN-4-VLAN_CREATE_FAIL: Failed to create VLANs 2000: extended VLAN(s) not allowed in current VTP mode
Cisco Switching/Routing :: 3560 / STP Loop Guard Blocking Vlans?
Mar 24, 2013I have a strange issue where spanning-tree is blocking vlans through a mesh network.Here is my set up.
2-Cisco 3560's that have two trunk ports set with do1q and a native vlan of 2. I'm allowing a client vlan (2) and a voice vlan (103) to come over the trunk. They have a native vlan of 2 so the mesh APs can get an address through DHCP. Spanning-tree loop guard is also enabled.
When connected to the mesh network, the voice vlan is being blocked by spanning-tree. I get the following erros:
000129: *Feb 28 19:24:58.289 EST: %SPANTREE-2-LOOPGUARD_BLOCK: Loop guard blocking port FastEthernet0/1 on VLAN0103.000130: *Feb 28 19:24:58.448 EST: %SPANTREE-2-LOOPGUARD_UNBLOCK: Loop guard unblocking port FastEthernet0/1 on VLAN0103.
Eventually the loop is cleared and the port is set back to a forwarding state from a blocking state. I don't want to disabled spanning-tree loopguard since I don't want to create a loop. The mesh network is supposed to act as a P2P connection between two switches. As a test I disconnected the APs from their trunk ports. I then used a cross over cable to connect the switches and no spanning tree loops occured. The mesh doesn't have STP enabled on it and should just be acting as an over-the-air connection from one switch to another.
Cisco Switching/Routing :: Sharing Internet Access Through A 3550 With 2 Vlans?
Apr 27, 2013They have a locked Cisco Router which is from the ISP and its confed on a fa 0/0 interface to share Internet access on the network. The ip on that interface is 195.198.11.217 255.255.255.252 and i tried it with a PC (set my personal ip to .218 and entered their dns info (195.67.199.27) and it is working. The question is now. My friend found a 3550 laying around and since the ISP wont let them conf their router he wants to use the 3550 to create 2 vlans with internet access and without access to eachother. Vlan 10 for the desktops and Vlan 20 for the wireless (Moving on to some netgear wireless switches) How would you configure the 3550 for this to work?

Apr 5, 2013i am trying to set up a cisco 2950 with a vlan to seperate all of the pos machines on the network (4 of them) from all other machnes in the building (3 hard wired and wi-fi). i was going to use vlan 1 as a trunk to allow internet access to go from fa0/1 to both vlans (vlan 10 and vlan 20). i have read things about the acl having an explicit deny at the end, so i'm thinking that is my problem. i am testing it at my house before deploying it to the network. i have 1 laptop setup with an ip of 192.168.0.50, and the other is .60. my router is 192.168.0.1. i have the ethernet from the router plugged into fa0/1, the 1st laptop on fa0/2 and the other at fa0/3. before i set the vlans up, i checked the communication by just plugging them in and trying to ping, they could both ping each other, the router and 8.8.8.8. when i finished setting up the test vlans, they could not ping each other(what i wanted) and laptop 1 can ping the router, and 8.8.8.8. laptop 2 cannot ping anything.
the only thing i did was create vlan 10 and 20, set port fa0/2 to vlan 10 and no sh, fa03 to vlan 20 and no sh, fa0/1 to vlan 1 and no sh. then i did switchport mode trunk on fa0/1, and switchport native vlan 1. this seems to be how i was supposed to do it, but it's been a while since i have worked with switches. i'm sure it's simple, but after searching the internet and poring over my cisco books for 5 hours, it is turning out not to be the case. here are some details:

Name: Fa0/1
Switchport: Enabled

Cisco Switching/Routing :: Internet Access For 3550 Switch VLANs?
Feb 22, 2012I have a small cisco switch cluster (seven different 2924, 3524cisco switches) with 3550 as a cluster control which does all the inter vlan routing that works fine.
This cluster is in semi production PBX interop testing lab. This is a closed network without internet access and not connected to our corporate network.However now I have to add this capability so some equipment in the lab can get Microsoft updates over the internet.
I've created a port on a 3550 (fa0/19) and connected it to another network that has internet access. It picked an ip address and when I'm logged in to the 3550 I can ping hosts on the outside network. However I can't ping any hosts on that network from any hosts that are connected to my vlans.I've tried a few different things, but still can't make it to work.
Here is a short version of my 3550 configuration:
!
version 12.2
no service pad

Aug 12, 2012I have 5 SVIs configured for VLAN Interfaces 121-125 for my vSphere environment.
All VMs can ping IPs on all the VLANs (VMs on VLAN 124 can ping VMs on VLAN121)
All VMs, except those on VLAN 124, can access the Internet or even ping my router IP.
If I change one of the VLAN 124 VMs to use a different VLAN, and update the addressing appropriately, it can access the Internet.
The problem is exhibited with Windows and Linux VMs. So, I believe something in my switch setup is the problem with VLAN 124 in particular.
If i do a show vlan brief, VLAN 124 is listed.
If I do a show ip int brief, VLAN 124 is listed as upup. I also tried to shut o shut the VLAN 124 interface.
Only one specific VLAN has connectivity problems?

Cisco Switching/Routing :: 2911 / 2960S - Multiple VLANs With Different Internet Access
Feb 17, 2013We need to give differentiated internet access to three VLANs. Each one of this VLANs is used for totally different purposes, so traffic between the VLANs is not allowed. Each VLAN has its own internet access provided for the data center using one fast ethernet connection.
We're thinking about using cisco 2911 for Internet access, VPN and firewall. I suppose that best option for VLANs is using Catalyst 2960S or a swithing module for the 2911, but these two options are too expensive for us. We're thinking about using swtiches from the SB series (maybe a SG-200).
We're totaly newbies to VLANs so we have many doubts. This are our questions:
1) The 2911 has three on board ethernet interfaces; we have three VLANs and three internet connections, so we need to use HWICs to get three more ethernet ports. That's right?
2) We need three HWICs or there is some kind of HWIC with more that one ethernet interface?
3) The routing solution is to assign static routes in the 2911 for each interface connected to a VLAN through a 2911's interface connected to internet?
4) Simply connecting three different router interfaces with three different switch ports, each one of them assigned to one of the three different VLAN, are we going to get internet access for all devices in those VLANs? or do we need to configure something else like trunking, VSIs...?
5) Can we achieve our goals using the SG-200 switch?
6) We have the chance to use older routers, is this possible? We're specially interested in knowing if a 1841 or a 2801 router could be used for this setup.
7) This is not a production environment so we can use refurbished equipment.
Cisco Switching/Routing :: Block Traffic Between Two Vlans On Cat3560C - Internet Access?
Aug 3, 2012I have a Cisco C3560CG which is running C3560c405ex-UNIVERSALK9-M), Version 12.2(55)EX2.The switch has vlan 1 and vlan 50 configured, vlan 50 should have access to a limited number of host in vlan 1.The following acl has been applied on the inbound to vlan 50:
10 permit tcp 10.16.30.0 0.0.0.255 host 192.168.15.243 eq 137 138 139 445
20 permit udp 10.16.30.0 0.0.0.255 host 192.168.15.243 eq netbios-ns netbios-dgm netbios-ss 445
25 permit icmp 10.16.30.0 0.0.0.255 host 192.168.1.243

30 permit ip 10.16.30.0 0.0.0.255 host 192.168.15.254
[code]....
I sure the above would work, but for some reason some of the packet counter are not incrementing but the traffic is being blocked. But I would like to see the counter increment.Also I have that I may beed to use VACL wouls this be the case?
Cisco Switching/Routing :: 3560 - Unable To Perform VLAN Routing

Sep 29, 2011I have no router inplace that can do trunking (5505 basic license )I have 2 VLANS 10 Data 20 voice I have given both VALNs IPs lets say
-VLAN10 192.168.1.1
-VLAN20 192.168.2.1
Enabled IP routing and set the router as the gateway of last resort.Now becuase the L3 switchis doing the routing I have had to set the default gateway as the VLAN IPs. So PCs on VLAN10 get a gateway of 192.168.1.1 and phones on VLAN20 get a gateway of 192.168.2.1
Any real downside to having the 3560 doing the VLAN routing, is this the "correct "way to do things in the event I don't have a trunkable router?
Cisco Switching/Routing :: 800 / Use ASA To Configure All The Vlans And Intervlan Routing And Access Lists?
Jul 4, 2012upgrading our small office network. We currently have about 75 employees with probably 125 devices on the network. I'd like to create about 10 vlans for the different departments and then configure intervlan routing as needed. Currently we have all unmanaged switches and it's just a huge broadcast storm on the network. We are upgrading our Cisco 800 router to an ASA5505 sec. Plus license. I need some recommendations on switches. Of course, this needs to be done as cheap as possible.... Is there a way to use the ASA to configure all the vlans and intervlan routing and access lists and use a cheaper switch to provide the access layer to hosts?

Dec 22, 2012I have set up a scenario for a small business and have some questions about how to manage the access between the VLANs. Is there is a better / another way to do it. See the attached picture for the topology / info.
My question is:
My switches is set up with x numbers of VLANs and a routed port (no switch port) to the ASA for internet connectivity. How is the best (or only??) way to manage the access between the VLANs? Is it ACL's on the switch?
And by "managing access" I mean VLAN 50 (public WiFi) only have access to the internet, only management servers have access to management VLAN, Client VLAN only have RDP access to server VLAN and so on. Is there any way to do this in the ASA (or add another (gigabit) router to the topology)) or it the only way to have lots of ACL's on the switch itself? I have thought about "router on a stick", but then I imagine there will be a bottleneck between the switch and the ASA?

Cisco Switching/Routing :: 3750x - Denying VLAN Access To Other VLANs
Mar 18, 2013I've got a 3750x stack set up as my core switch (only a small-ish environment) - I'm shortly going to be deploying an enterprise wireless network with Corporate and Guest SSID's. I'm going to be putting all traffic from the Guest SSID in VLAN 244, and don't want it to have access to any of the other VLANs (1 (Legacy Eqpt), 4, 8, 12, 16, 20, 24, 28, 32, 248 & 252).
IP ranges for all the main VLANs are:
1: 10.0.0.x/22
4: 10.0.4.x/22
8: 10.0.8.x/22
12: 10.0.12.x/22
16: 10.0.16.x/22 etc etc (you get the pattern)
I'll probably give Guest traffic (VLAN 248) the IP range 192.168.10.x/22 (not because I NEED that many addresses, but it's easier for everyone to remember/understand if I keep the subnet masks the same all round). However I also have a CCTV VLAN (252) which already has the range 192.168.0.x/24, which some people in other VLANs WILL need access to.
So my question is: What is the syntax for the ACL on my 3750x (IP base - 15.0.2) to prevent traffic from VLAN 244 gaining access to any of my other VLANs. I'm making a broad assumption here that a layer 3 switch is perfectly capable of supporting that function? I need ALL the syntax for setting up ACL's - I've never done it before
My gateway device by the way is 10.0.4.1, and I do have inter-VLAN routing set up on the core switch (obviously).

Jan 29, 2012Here is what I have. Windows Domain Controller running DHCP with configured scopes.I have one ASA5510 And 4 HP Procurve switches with VLANS preconfigure from vender.
Here are my DHCP scopes/VLANS:
VLAN1 -Default 10.2.x.x/17
VLAN201 -DHCP 10.2.201.x/24
VLAN202 - WLAN EMP 10.2.202.x/24
VLAN203 - WLAN Guest 10.2.203.x/24
VLAN 252 - MGMT 10.2.254.x/24
Here is how I configured the DHCP Scopes:
Changes needed to make to the DHCP Server (AUSPDC) in order to get things working with the new switches.
1) Configure 3 new DHCP scopes on your DHCP server.
a) scope for 10.2.201.x/24 to serve LAN employees and give them a gateway address of 10.2.201.254.
b) a scope for 10.2.202.x/24 to serve WLAN employees and give them a gateway address of 10.2.202.254.
c) a scope for 10.2.203.x/24 to serve WLAN Guests and give them a gateway address of 10.2.203.254.
I just upgraded and decided to go with the VLAN configuration. None of my VLANS can get out to the internet or each other due to I think My ignorance in configuring the firewall.The PC's are getting proper IP address but they cannot get out or to the other VLANs. I tried to duplicate what is working for VLAN1 but it is not working.
Here is my config.
