Cisco Switching/Routing :: Assigning IP Address To VLANs In SGE2010P?
Apr 9, 2012
Recently purchased 5 SGE2010P 48-port switches to replace older L2 switches. I have 4 switches in single stack and one as a standalone. Both the stack and standalone will connect to at least 1 Dell 2724 switch. Both the stack and the standalone Cisco are in Layer 3 mode.
I have created several VLans on the Cisco switches, and am trying to assign an IP address to the VLan, but cannot seem to figure out the web gui. Each time I try to use Systems > System Management > IP Addressing > IP Interface, then click Add, it simply changes the existing IP of the management interface. So, I'm not sure how to go about assigning an IP Address to an Vlan.

I just want create vlans on switch sge2010p
Scenario:
vlan10
ip address 192.168.10.254/24
vlan20
ipaddress 192.168.20.254/24
vlan10 needs internet.
I have a static ip internet which is 200.33.22.11 gateway: 200.33.22.10 I have a router configured working as gateway, It has ip 192.168.2.1.
I have configured two vlans. But when I try to check if vlan has internet, it doesn't work.

I'm fairly new to Cisco configuration and I am looking at a problem for a client that involves the use of a Cisco 887 (wired only) as the main router/gateway. The problem I am investigating involves the allocatoni of DHCP addresses from the device to a product we have designed that connects to the router. I am attempting to set the 880 up on the bench with no ADSL connection and just use the DHCP feature of the box for the 4 switch ports on the back. I have tried all kinds of configurations from default. Whatever I do I can't get the router to assign an IP address to anything that is plugged in (Windows or Linux machines). What could I be doing wrong ? It can't be that difficult to get the system to just act as a DHCP server.

The DHCP/DNS server is on ip address 10.1.100.103 with an alt on .102 I'm attempting to integrate a 4510R+E into an existing network and use existing DHCP/DNS windows 2008 server to push out IP addresses to connected computers.
I want to assign a VLAN to every port for management purposes and then I put an IP helper address on every VLAN.
I've attached a the 4500E partial config. I'm attempting to get Gi1/44 to a state where I can plug a computer into it an resolve an ip address and gain internet access like all the devices on the existing network can do.
I've created a new scope in DHCP with the ip subnet of 10.60.211.0 255.255.255.0 It leases addresses from .1 to .253
The computer will not resolve ip addresses with this config.

Created 2 separate VLANs on SGE2010P switch. Neither in Native VLAN 1.
For example;
-Port g01 in VLAN 56
-Port g25 in VLAN 56
-Port g10 in VLAN 10
-Port g37 in VLAN 10
All appears to work well within the respective VLAN (i.e. DHCP, ARP, etc. no IPs from other VLANs)STP - Spanning Tree is Globally disabled.
However; when I feed a n new network (which has STP enabled) into VLAN 10; I then plug a laptop with wireshark running into VLAN 56 - cannot see any other traffic/packet...except STP packets coming from a CISCO device on VLAN 10 while I am plugged into VLAN 56.
This demonstrates to me the network is not truely seperated. I know this because last night I crossed two networks and caused havoc; ouch.I configed a D-Link switch with the same scenario and no issue.

I am trying to give an static ip address to a time clock on my network and for some reason when I connect time clock to network it will always get an ip address from a different network. for example my computer IP address is 192.168.2.70 when connected to network, my default gateway is 192.168.2.1, the IP address that the time clock always gets is 192.168.1.120, there is no way to tell the time clock what IP address I wanted to be it has to get it from router (that is what the manufacturer told me), router (16portLiksys) does not have DHCP enabled the guy who set up network left it disabled, on his notes he says server (dell server T110) is acting as router is that true that a server can be acting as router?what do guys think is going on here?all the computers hooked up to network have static IP address.I also notice that when I connect a computer to router it will get an IP address from different network the same as time clock.I tried to reserve ip address on router by entering MAC address from time clock but it won't work. I am not very familiar with the server settings I have not try changing settings on server, I am not even sure the guy who set up network is right about using server as router.

My company wants to create a VPN Tunnel to allow a remote office to connect to ours. I purchased 2 ASA 5505 and I was expecting to be able to set this up without any issues. Sadly, that is not the case.
What I'm having trouble with is configuring my Public IP Address to the device. I go through the setup wizard and enter the IP Address like normal, but I have no option to input my ISP's subnet, Gateway or DNS. Without those, I get no internet connection. I know there is a way to do this, but I'm stumped.
My Specs:
2 ASA 5505 series
ISP Modem (Which they control) - SMC SMCD3GN with DHCP disabled

HP wifi printers (I've had 2 over the last several years)eventually have a disconnect with my wifi router and was told (by an experienced IT guy from my last job) I should assign the printer a static address to eliminate the problem. How can I assign a static address to my printer. Here are the models Router: Belkin model F5D9231-4v1(01); Printer HP Officejet 6600. I know how to access the printer and manually enter an IP address and subnet and such, I just don't know which numbers to use where. I also know how to access my router, via typing in the IP address in Internet Explorer, but i'm unsure of which tab within the router's page (i.e. is it category wirelessunder MAC address control) or which numbers (IP address or MAC Address)and where should I get the correct numbers from (i.e. go run, cmd,IPconfig/all).

I am using Windows 2011 SBS and Windows 7 clients.My server has a DHCP range of 192.x.x.150 to 192.x.x.199 and all other I.P. addresses are static. On a workstation located at I.P. 192.x.x.13 I am seeing an address conflict.When I perform an "nbtstat -a 192.x.x.13" command from the server I am given the logical computer name of a staff members personal laptop.Investigation of the laptop reveals that it is set to DHCP, and clearly the address of 192.x.x.13 is outside of my servers DHCP scope, so this I.P.should never be assigned, let alone in duplicate.I Google this topic before posting, and it was suggested that IPv6 could be having an adverse affect. I determined this because I performed a ping on the laptop and only got a MAC address back rather than an I.P. address.However after unticking IPv6, and rebooting, the laptop is still causing havoc.I can set a static I.P. address on the laptop, however this is not ideal.

We once had a virtual server with two network adapters, one was internal and the other was external, and people could access it directly from the internet.
That server recently, died (someone put the .VHD file on a massive RAID 0 array, and that went boom), and I need to set it back up again. All the DNS entries appear to still be there, but how to assign the external IP to the network adapter. I tried Google, but my Google-fu must be weak today as I can't find anything useful.
It's a Server 2008 R2 machine running inside Hyper-V. Nothing's changed except for the new Windows install, it's running with the exact same VM settings, which I didn't touch except to add a new VHD.

I just got a brand new laptop and I can't get it to connect to LAN.It's plugged in to the same hub as my main machine and I can't even access my router UI.It's not the cable because I tried plugging in my main machine's cable to the new laptop and the same thing happens.ipconfig reveals an Autoconfiguration IPv4 Address of: 169.254.197.187 But that number should say 192.168.1.1xx I've tried uninstalling and reinstalling the Ethernet driver as well.I've tried resetting the router and modem.I've tried resetting TCP/IP.

hrome threw me a DNS lookup failed. I go into my network settings and I noticed that I had limited connectivity. It would switch between no network access and no internet access every few seconds. After a bit of fiddling around, I got it to connect through assigning myself a static IP. This isn't exactly convenient because I use this computer on multiple networks. When I try to have it on automatic IP, I get no IP address or default gateway when I do an ipconfig /all. It would appear that my router quit assigning my laptop an IP for no reason whatsoever. DHCP is enabled on the router, and all other devices work fine. What could possibly be the problem here? I'm 99% sure it's not an IP conflict either. It's not being MAC filtered because I'm on the thing right now posting this through a static IP. It's not my A/V because it's worked great in the past. Perhaps I should also mention it occasionally says "unidentified network" instead of the SSID

Is there anyway you can assign a static IP address within WAG160Nv2 to peripherals such as an XBOX?
The knowledge base only seems to show how to assign an IP address in the XBOX but when I have to reboot the router, I've noticed the XBOX is assigned a new IP address when viewed in the router pages.
If I set a permanent IP address in the XBOX, this will no longer match what is in the router.

upgrading 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?

I have the following config using a Cisco 1921. I am trying to get devices on the the native VLAN to get internet access via the gateway x.x.x.73.Any thing being routed from the other Vlans 15/20/30 can get access, but nothing from an internal IP address. Is there something I am missing.
The Xs replace the same 3 octets for each interface.I am trying to route from VLANs 15/20/30 to see VLAN 5. I have tried a few things, in terms of adding extra ip routes, but can't get anything to work. Each of those Vlans have another router on the other side of them, which I have also tried adding ip routes too, but nothing. One of the routers (Vlan15 is a Draytek 2830). [code]

I have purchased these two switches from ebay as a test lab, I plan to connect them up via a gigastack modulecable and enable ip routing on the c3550 and vlans to talk to each other.
I'm very much a procurve person and really need to get into the cisco switching.I will want to trunklacp between the switches - whats the process is setting that up on cisco switches?

I have configured the above switch with 2 vlans, with vlan interfaces and a default route that points to an internet router.
The switch is running in Layer 3 mode
================ ================
= = Vlan5 = =
= SGE2010 = ++++++++++++++ = Draytek = ------------------ INTERNET
= = = =
================ ================
192.168.0.254
Vlan 5 Data
Vlan 10 Voice
Int Vlan 5 192.168.0.253/24
Int vlan 10 192.168.10.253/24
0.0.0.0 0.0.0.0 192.168.0.254
The inter vlan routing works fine with the .253 addresses as the default gateway to the PC's but I cannot browse the internet.
When I change my gateway to the router .254 address, I get out on the internet fine.

I am setting up a vm environment for a customer in my lab off site. I have two stacked 3750-x switches, a san, and threes UCS c220 M3S servers for hosts. I am trying to separate the lan traffic, san iscsi traffic, and san management traffic using vlans. The problem is i'm unable to communicate cross vlan with my current config, which I have attached to this post. The only noteworthy things in my conifg is that the ip route 0.0.0.0 0.0.0.0 192.168.83.6 is referring to a switch stack they have on site, that I will connect this stack to using the first two trunk ports on each switch, that I do not have here in the lab. I don't want to cause any confusion in why I have things set a certain way.

I have tried to test copy tftp: numerous time with no success. I believe the reason it is failing is my laptop to Ethernet port is in vlan 62 and the tftp process operates in a different IP space.I am using gig 7/1 and configuring my laptop nic for x.x.x.254 mask 255.255.255.0. I can ping from laptop to gateway) and I can ping from the switch to my laptop using ping vrf production x.x.x.254. Can you tell me what vlan I need to set my laptop connection in or if there is something else I need to change to make tftp work on vlan62?Does TFTP only work in vlan1 or can it be changed?

I recently set up a Cisco 881 to cover a small business network. The router is currently set up and working as expected. We recently decided to move to VoIP phones and here is where I'm running into some issues.
First an overview: We run a network with a cable internet WAN connection, this connection is DHCP, however we have a static IP through our ISP. We also have a block of 30 additional IP addresses for one to one mapping as we need them. The new VoIP system is being run over T1 lines throughout the township (we are a municipal organization) and the VoIP system is being run to about 5 buildings in the township.
This brings me to the topic of VLANs. As the phone engineer explained it to me, there is a network set up over the T1 that allows the VoIP equipment to talk to one another and operates all of the VoIP phones on one network. The equipment that is being installed at our building connects to the network over the T1 and "talks" to the other equipment on the network. The engineer wants to create a VLAN and run it on ports fa1 and fa2, with the fa2 port being connected to the actual "MPLS" (their term) that connects to the T1 and into the cloud, and the fa1 port connected to the internal phone switch.
TLDR; The problem is this: When we attempt to set up the VLAN on ports fa1 and fa2, we have no connectivity with the other units in the external VoIP cloud. Pinging while directly connected to the "MPLS" yields successful pings, while pinging from the router with the "MPLS" connected to fa2 yields failures. I'm going to post the running config below, I feel like what we're doing should be working. I asked around about subinterfacing, but others seemed to think this was not necessary.

I am working on getting my CCNP. The first exam I plan to take is the switching test BCMSN 642-812. Using the 4th Edition Self-Study Guide from Froom, Subraniaman, and Frahim.In Ch-4 it talks about End-to-End VLANs and Local VLANs. I read that section 4 or 5 times and still did not understand the difference between them two.I know one spans across the entire network and the other is local. What do they exactly mean by that?

I have the need to filter multicast between vlans as described below. PIM Sparse-Mode is being utilized for this multicast network and changing any Vlan to PIM Dense mode is not an option.
- Vlan 217 and Vlan 4 should not be communicating on mcast with any other vlan, including eachother (each vlan isolated).
-Vlan 64 and Vlan 80 are able to communicate witch each other on mcast but not with any other vlans (isolated vlan group).
-All other vlans can communicate mcast freely.
What I've created thus far is below. It does not appear to be the most elegant solution and would be difficult for the administrators to adjust as new requirements come along. Yes, I will be adding the appropriate link-local multicast addresses so as to not break routing and other dependent technologies.
ip access-list ext ANY_CONN
permit ip any any
ip access-list ext MCAST_INTRA_217
permit ip 224.0.0.0 15.255.255.255 133.106.197.32 255.255.224.0
permit ip 133.106.197.32 255.255.224.0 224.0.0.0 15.255.255.255

We have the need to create a large number of VLANs on one of our networks. We're talking about 60! These will all terminate on a pair of 6509-E switches (building core). We use MSTP as a standard on our network so I'm going to stick with that so that we can dramatically reduce the number of STP instances needed. However, regarding the SVIs (default gateways) is there any reason why creating 60 of these guys would be considerd a big no-no? Or would you expect the 6509s to deal with them like a boss?

I need to set up a VLAN. We just bought the SG500x switches and we need to create several VLANs.
So for example:
192.168.1.x --> Vlan 1
192.168.2.x --> Vlan 2
192.168.3.x --> Vlan 3
What I would like to know is how do I come about setting this up and do I have to do something with my DHCP server to allow this to happen?
