Cisco Switching/Routing :: Creating A VLAN On 2800

Nov 20, 2011

I have a problem to create a VLAN with a Cisco 2801.,I need to have base ports FastEthernet 0 / 0 and FastEthernet 0 / 1, in the same VLAN.
Basically I'm trying to switch access redundacion, now I have redundant switches in which I have the servers, but if one of these switches fails, and,coincidentally is where I have connected the router, the server runs out of internet connection.,I idea is to connect the FastEthernet 0 / 0 to a switch, and FastEthernet 0 / 1, to the other switch,but I managed to have these two ports in the same vlan, in order to have a unique IP for both FastEthernet ports,As I can do this?. do is a lot of documents using the switchport command, but this command is not available in my router, I tried different IOS, and nothing.,currently I have the following IOS: c2801-adventerprisek9-mz.124-24.T6.bin

Cisco LAN :: 6509-e Switch And IDF Closets Have 3750 - Creating Isolated VLan

May 6, 2012

My core switch is a 6509-e and my IDF closets have 3750's.I have a couple of vlans currently setup, that can communicate with each other.VTP is setup Client/Server where as my core is Server, all IDF's are Client.
What i'm trying to do is create an isolated VLAN.  I want to setup a DHCP scope and use helper address.  When i plug in a client to that VLAN, i want it to get an IP, but not have any other network access.
Is this possible to do without switching to Transparent mode? If not - what reprocussions will i see by switching to transparent mode?

Cisco Switching/Routing :: SG200 / 3550 - Creating VLAN And Isolating PC On Network

Feb 12, 2013

I was given a task of creating a vlan and isolating one pc to access an internal website ( on a specific port (port 8080)The pc is connected in the following manner:

PC--> HP Switch --> Cisco Small Business SG200 switch --> 3550 Catalyst 1, 3550 Catalyst 2 and 3550 Catalyst 3.

I have created a vlan 110 on the Main 3550 Catalyst switch and successfully added the pc to that vlan.However, that PC must be able to access the internet and an internal website on port 8080.I have placed an access-list on the main 3550 catalyst switch which is connected to our router as below:

Client ip address:
VLAN 110:
access-list 110 permit tcp host host eq 8080access-list 110 permit icmp host anyaccess-list 110 deny ip ? I was unable to access the webserver even after many attempts.

Cisco Switches :: SG200-18 - Losing Access On Random Ports When Creating LAG

Aug 3, 2011

I  just bought a SG200-18 in order to use LAG between a backup server and  multiple computers and servers. Servers are supposed to all use 2 links  and computers only 1.
As  soon as I activate LAG on port 2 and 3, no matter what is connected on  the switch I lose access to the switch interface (luckuly, it's still  working on port 17 for a strange reason) and all computers / servers  connected are randomly losing the network access. Everyrhing start to be  slow but most servers and computers don't lose access to the internet.  Browsing a web site will suddenly take ages but... it will work  eventualy.
I already used LAG on other switch without a single issue.. The only uplink I have is to the router and I know that I don't have any issue with network cables....
So  what am I doing wrong ??? I didn't even try to configure the TEAMING on  the servers, just creating LAG on the switch will kill everything Oo.. I'm starting to think that my SG200 is dead out of the box.

I have been working with ASA 5510,20,40,80 but not with 5505 this vlan and its interfaces are quite confusing.Just want to know how it works and its connectivity to Cisco Switch.Do i have to put the interface of the switch in the same vlan as i am creating the interface vlan in firewall ?Now the switch port connecting to this Eth1 interface should also be in the same vlan ? i.e vlan3 ?? or it will be in trunk ? The default configuration shows the eth0 with no access vlan and interface eth1 with access vlan 2... does it mean the eth0 is in vlan1 ? (Nativ Vlan ) ???

Cisco Switches :: VLAN With 2 Switch ESW - 520?

Jun 13, 2011

For test I used 2 Switch that name "ESW X" and "ESW Y" I have 2 network that I named "Network A" and "Network B" I build 2 VLAN for each network that named Vlan 2 for Network A and Vlan 3 for Network B, I don't use Vlan 1 because it's the default Vlan 
Configuration ESW X:
port e1 : ACCESS PORT on UNTTAGGED Vlan 2
port e2 : ACCESS PORT on UNTTAGGED Vlan 2
port e3 : ACCESS PORT on UNTTAGGED Vlan 3
port e4 : ACCESS PORT on UNTTAGGED Vlan 3
port g3 : TRUNK PORT with UNTTAGGED Vlan 1(default) and TAGGED Vlan 2 and Vlan 3

Each Vlan can't communicate between the two switch, I think they're a problem in my vlan/port configuration?

I bought for a little office  a SA520 Security appliance (for future VPN with another distant office) and a SG 300-10P switch for connect 3 PC and 3 IP PHONE. THe SA 520 is the router. I must configure 2 VLANs on the switch :

VLAN2 : DATA (for PC)
How can i simply configure all ports ? I would like to configure ports 1-4 on VLAN2 and ports 5-8 on VLAN3 and port G10 is reserved for the router SA520. I want to divise network DATA/VOICE.
I think i must create a trunk on G10 for SA520 ...

Cisco Switches :: SG 200-50 VLAN Configuration

I'm adding it to an existing infastructure, with multiple VLANs.  I believe I have it set up correctly, however whenever I daisy-chain the switch in with the trunk ports, it's not passing the VLAN info correctly.  There's not a lot of configuguration involved, so I'm not quite sure where I might be going wrong.  I've attached a couple screenshots that show my trunk port configuration.

Cisco Switches :: VLAN Tagging Across From Firewall To Two SG-300

I need some assistance in setting up VLAN's (802.1Q) accross two switchs, I want the same 2 vlan's on both switchs, how do i configure them to be connected and pass both vlan's traffic.VLANs from firewall are tagged at 3 and 8.Single port out from the firewall.The first switch is simple enough, port is connect at port 52 and configured from both vlan's then the individual ports are either on one or the other.  The question is how do i connect the second switch so that it can also do both vlans.  Assume I connect switch1 at port 51 to switch 2 port 52.  Do I configure both ports to be on the same VLAN's. or do i setup LAG's.

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

Jan 26, 2011

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.

Cisco Switches :: VLAN Tagging ESW-540 And 3750g

Aug 19, 2011

I am currently tasked with setting up a network, pretty much from scratch, that requires some fairly hefty VLAN deployment. My hardware on hand (already existed so can't can't change anything easily) 5x ESW-540-48 Switches, 1x3750g switch, 1x2811 router.  I don't believe the router should be required as the 3750 is capable of intervlan routing. [code]
Now at one point I actually had the VLAN's *working* in that I could specify an IP address and could ping to and from it!  However DHCP wasn't passing despite numerous attempts with DHCP relay and IP-Helper configurations.Also I was having issues with VLAN 1 as the native VLAN, the ESW switches don't allow you to do much with them, as they 'weren't created by the user'.  So tried switching that out to VLAN11 also but with very little success there (I had to change the native vlan on all trunks to VLAN 11)All the 10.x.x.x addresses need to be able to communicate with each other.All the ESW switches need to be able to handle their respective VLAN's as well as VLAN 1 (for Printers and wireless access points distributed around the building).

Cisco Switches :: VLAN Config On Sg300?

Jan 26, 2012

I am using a couple cisco sg300 28P switches along with a sonciwall firewall/router. The sonicwall was already in place and working so they didnt want to replace it. I understand how to configure the vlan on the sonicwall, but could use some info on the cisco. I would basically like to create 3 vlans, 1 default for management, 2 for pc's on lan, and 3 for the cisco spa504g phones/'voip. Would i just go into the vlan managment, configure the 2 new vlans and give them two id's? These offices have one network drop, so the phones and pc's will be sharing the switch ports, however the phones have a setting to configure the vlan id so they know which one theyre on. Is there anything i need to do after that? I want to make sure that vlan 3 has the highest priority becuase its voice, is there some qos configurations i need to make on that switch as well? Also, the port that links the two cisco swtiches together, does that need to be set as "trunk" port? I understand what vlans are, but its just the first time ive run into these cisco models. .

Cisco Switches :: 2620 DHCP Through VLAN

Jan 18, 2013

I have a 2620 Cisco Router plugged into a 2924 Cisco switch by a trunk.The vlan configuration works, I subdivide my router interface with dot1q and have virtual machines on different vlans and everything works perfectly.The problem comes with a DHCP request.Let's say that I have my local lan on the native VLAN 1. I create a VLAN 25 in the switch and create a fa0/0.25 in the router.In the switch, I plug the cable modem from my ISP in a port on vlan 25In the router, I go to fa0/0.25 and issue "ip address dhcp".The DHCP request goes out, but never comes back. The problem seems to be in the switch because if I try the same thing with a virtual machine I have on a trunked VMWare ESXi server, I get the exact same results. I just don't get the IP address from the ISP.The next step would be to monitor the port on which the cable modem is connected and sniff the packets to see if the DHCP request actually gets back through.

Cisco Switches :: SG300-10 VLAN Configuration

Apr 22, 2012

Before I launch into this can I say that I am very much a novice with regards to Managed Switches and their configuration. I have the following equipment which I have connected to the switch: [code] All of the above are on subnet of the above communicate with each other during normal operation.Our client is connecting to the switch but his requirement is for his system to "see" the PLC Comms Card as follows:IP: on Subnet .
Using the Internet Explorer interface connection I have created an additional VLAN (ID 2) on Port 10 with the intention of using this as the connection to the client ( I assume there will be further settings required to route the PLC connection to this port) but every time I try to assign the IP and Subnet values and click "APPLY" the changes are not made and the connection appears to hang leading me to reboot the switch.I have connected to the switch via console and changed the mode to Layer 3.  I also assume that it is OK for the three pieces of equipment to remain on the default VLAN. How I should setup this VLAN and ultimately achieve my goal.

Cisco Switches :: Get Vlan Communicate On SG300-20

Mar 28, 2013

I am facing an issue to setup what I initially called simple network but still unable to put it together.On SG300-20 I want to setup 4.3 of the vlan are to separate users in to different groups and to secure data confidentiality.1 is for the NAS. All users on the 3 vlans must access the NAS vlan.All user should have access to internet via SG300 through the ISP provided router. How to configure this, I have every little knowledge of switching and routing? And the routing seems to be the issue I am encountering because I am able to create the VLANs and assign static IP address to them but not able to get them talk to each other. I use each vlan ip as gateway on each port assigned. [code]

Cisco Switches :: SG300- Use Multicast TV VLAN?

I want to use Multicast TV VLAN with my SG300-10 to join Multicast Groups in different Data VLAN's. It's working fine, but the problem is that it isn't possible to add all the Multicast Groups to the Multicast VLAN because each TV channel use other groups. For me it's only to handle if I can use wildcards to add a specific range of multicast traffic to the Multicast TV VLAN. Is that possible with that Switch?
