Cisco Wireless :: WLC 5508 / Cannot Create Interface As Same Vlan Id And Subnet

Aug 12, 2012

I have got a wireless project with WLC  main office and have 10 sites where ap's are there and ap's getting registerd .we need 4 ssid in all branches same .

ssid guest
ssid scanner
ssid user
vlan 600 main office for scanner 192.168.1.0
in branch
vlan 600 for scanner but ip is 172.16.1.0

and bgp is running . And customer is asking me not to edit the ip range or vlan or create new vlan . but in wlc am not able to create branch network 172.16.1.0 range interface and vlan 600 as vlan 600 i already created for scanner main office 192.168.1.0 So is there a way to do that .
 
Temprarly one site i did like created vlan 610 in branch no ip . And in main office interface vlan 610 given another ip range . and i created interface in wlc . from branch i can connect the ssid and getting ip . But they dont want to create any aditional vlan or another network . Customer dont have a smartnet contract . They recently baught 2 wlc 5508 and 40 ap 1142.

Cisco Wireless :: WLC 5508 Cannot Create AP-manager Interface

Aug 9, 2012

Yesterday I was in one of our client premises configuring a WLC 5508 with software 7.2, went through the initial configuration wizard with no problem whatsoever, my issue began when trying to configure a ap-manager interface.In many WLC configuration guides cisco states that for 5508 it is not required to configure an ap-manager interface because the management will suffice, but then they put a side note recommending it's configuration for best practices and better performance. OK so I saw that in an earlier version document and now they do not make the recommendation but the still use the word required and for me that's still is not a limitation. I can't create the ap manager interface because when I put the VLAN ID it says the it is being used by another interface.

Cisco Routers :: RV220W Can't Create 255.255.254.0 Subnet

Nov 8, 2012

I'm trying to setup this router with my IP range 192.168.100.1 to 192.168.101.254 but if I try to enter a subnet mask other than 255.255.255.0 I get the error - Invalid subnet mask. It should be 255 for given class of IP address at 255.255.xxx.0.
 
Every other device on my network allows that subnet mask, why not this router, it's stopping access from my 192.168.101.x devices.

How To Connect 2 Routers LAN - WAN And Create Subnet

Sep 8, 2012

I'm trying to connect two routers and create a subnet but failing due to a little knowledge but no real understanding! I've read the ultimate setup thread loads of times but can't get my setup to work.

Here's the setup I'm trying to build:

Internet -> Master ADSL modem/router (No NAT, no DHCP) -> Slave cable router (NAT, DHCP)

I want to connect 3 Xboxes to the master router with external IPs to avoid the whole "moderate/strict" NAT nightmare. Then I'll connect everything else (PCs, Macs, wireless devices etc) to the Slave router which will assign IP addresses and do the NAT thing. Both routers are Netgear N150s (master is ADSL, slave is Cable).

Here's what I've tried so far:

Master router:

All IP addresses supplied by ISP
Internet IP: xxx.68.160.143
DNS: xxx.xxx.3.xxx and xxx.xxx.6.xxx
Router IP: xxx.68.160.142

I can't access the bvi interface I use to manage the AP1261N from an IP address that is not in the same subnet of the bvi interface. The AP is configured as root bridge. Obviously I've the same behaviour for the non-root AP connected to it. For sure it's an ap configuration problem as other devices in the same vlan (vlan1) are reachable by the vlan I'm connected to. This is the conf:

Protocols / Routing :: Partition Departmental IP Network Address Block To Create Staff / Student Subnet?

Sep 28, 2011

partition the departmental IP network address block to create a staff and a student subnet. Each of these will be identified by its own network address and netmask. It is university policy that you must be economical with the IP addresses. That is, the subnets must be as small as possible, but they must be large enough to accommodate the maximum number of hosts you were given. Also, it is university policy that the respective gateway router to the outside world should always be given the highest possible host IP address in the subnet. The student subnet should have a higher IP network address than the staff subnet. The network must be able to support up to 60 machines on the staff subnet (not counting the router) and up to 120 machines on the student subnet (also not counting the router).

IP address/netmask
University network address127.158.128.0
University network mask255.255.192.0
University internet gateway IP address127.158.191.254
Department network mask255.255.254.0
Department router address127.158.129.254

Suppose that the network address of the departmental network is 127.158.128.0 (calculated by AND between Dep network mask and Dep router address)I know that 60 machines would use 6 bits for the staff subnet.the netmask of staff would be 255.255.255.192.how can I figure out the the IP network address of the staff subnet.I have worked out the range for the staff subnetwork.

127.158.128.0 - 127.158.128.63
127.158.128.1 = Gateway address
127.158.128.63 = Broadcast address

Now how can I calculate the IP network address of the staff subnet?

Multiple Vlan / Subnet Network

Apr 4, 2011

I am designing a network right now that is going to have 356 devices. I need to use vlan separation with subnetting for a number of reasons. The first (and most obvious) is that there are 356 devices that will require an IP. Too many for one subnet. The second is that a good portion of the devices that I am using are a litlle to chatty with the broadcast traffic for my comfort. I have two subnets that are going to be specifically alocated to these chatty devices. Our switches are being provided for us by the client for unknown reasons. They are providing us with HP ProCurve E2810 switches which are layer2 switches.

Cisco :: Routing Traffic From Non VLAN To VLAN On Same Interface?

i'm going mad on following problem. I'm trying to get 2 networks seeing each other while one of the network is a non VLAN network and the other one is a VLAN network.They should use the same interface so i added VLAN e0/0.122 to the interface e0/0.Send a ping from my asa to both gw-IP's made me happy at first. In second in figured out that i cannot reach any client in the other network. For testing purpose i created an permit acl to any/any for both networks, but the packets still get dropped by the default implicit rule. (deny any/anyMaybe i'm to stupid for this

Cisco Switches :: SGE2010p / Configure Vlan To Reach Few Subnet?

Jun 9, 2010

Just got a new SGE2010P layer 3 switch. I'm trying to configure Vlan to reach a few subnet. I have the original 192.168.1.0/24 as vlan1. I want to reach our WiFi subnet 192.168.10.0/24. The WIFI router is directly connected.  It's new for me as the previous Job i was sorking with a ws-3750-48.
 
i did from console  change my switch to layer 3 mode... ( i want it as the DGW for each Vlan)from the web interface, i create a vlan4 for our WIFI Next i go to ipv4 to add an IP address to vlan 4 like 192.168.10.254 /24 As soon as I apply the IP the switch stop responding, Ping request time out..  i need to reboot the switch..

I'm new to Cisco equipment much more familiar w/ Sonicwall w/ that said......I have a 5505 w/ Security Plus licensing
 
I have set up multiple VLANs as follows
 
VLAN 1 inside - still setup as 192.168.1.1 (will not be using this for our lan)
VLAN2 - outside
VLAN100 - LAN 10.1.1.1/24

If I do add all the VLANs above I understand I will probably have to make a trunk port since I only have 5 usable interfaces

Way To Create VLAN

Mar 26, 2012

I wanted to have 3 vlan for my switch just for security reasons.(We do not want different Vlan members interact with each other)

I created 3 untagged Vlans on 48 port switch.

So ports 1-16 in Vlan 192.168.1.1/25

So ports 17-32 in Vlan 192.168.2.1/25

So ports 33-48 in Vlan 192.168.3.1/25

Cisco Switching/Routing :: SG 200-26P Cannot Access Web Interface From Different Subnet

May 24, 2012

Got a shiny new SG 200 26P which seems to work fine operationally.owever, when I am trying to access the web interface from a different IP subnet, the web brower just times out.If I put my PC on the same IP subnet, it works just fine. From the other subnet, I can ping the switch fine. The default gateway is set on the switch, and from the web interface I can ping and dns resolve other hosts and on the internet. I've tried to create a management profile to 'allow all from everywhere' basically, but still no luck.I'm completely stumped.  I've tried to reset to firmware defaults, and I'm now runinng the latest firmware. I woudl suppose that the switch would allow itself to be managed via the web interface from all subnets by default. Any thoughts?  The fact that the switch can ping internet hosts makes be believe it's own default gateway and IP are all ok and working.. (and I can ping it from anywhere in my network).

Cisco Wireless :: 5508 / AP On Different Vlan Than Controller?

Sep 30, 2011

I have a 5508 controller at our headquarters and am installing some 3502 AP's at a remote branch.  Unfortunatly, the remote branch has a different Vlan setup for some reason and the vlan that is used for the WLC (90) is designated for telephony at this branch.  Can I put the AP's on a different VLAN (10) without having any issues?  I will still use DHCP option 43 to point them back to the controller. Below are the configs for the WLC interfaces and what I am proposing for the AP interfaces:
 
WLC Config
 
interface GigabitEthernet1/1/38
description WLC01
switchport
switchport trunk encapsulation dot1q
switchport trunk native vlan 90
switchport trunk allowed vlan 1,10,50,90,91,390,410-413,610-613,800,810,811
switchport mode trunk

Cisco Firewall :: Changing Subnet Mask In An ASA5520 Interface

Aug 8, 2012

We have an ASA 5520, working fine.One of the interfaces is connected to users PCs and printers mainly. Last months the number of devices has grown rapidly, and we would like to make some changes in it in order for it to be able to host new devices.We thought on change subnet mask of actual subnet (10.0.2.0/24) to 10.0.2.0/23, so it can hold as many devices.I understand I have to make some changes in the ASA, but my question is:What will happend to the acces rules I have created?Will I need to create them again? There are some objects which carry information about subnet mask, so I suppose I will need to redefine them, but for those without any subnet mask information, will I have to redefine them?

Cisco Switches :: Correct Way To Create VLAN On SF 300 48P

On  our HP switches we have an 'Outside' VLAN where any device connected to  these VLAN ports can use the ISP's 'outside' IP addressing for direct  Internet access to bypass our firewall. We use this for  videoconferencing devices.What is the correct way to do this on a Cisco SF-300-48P??Presently I have ports 1-4 in vlan 50 Outside as 'untagged,' and the same ports as 'forbidden' in vlan 1 Default. Is  this the correct configuration?? In HP switches these ports in vlan 1  Default would be configured 'No' and 'untagged' in vlan 50 Outside.Tried talking to Cisco but their phone support is not working.
