How can i add two data vlans on cisco 2960 on one interfase? i have 3 mac adresses on one interfase: one PC, one ipphone and one XP virtual machine(VM). PC and VM are in one data vlan and phone is in voice vlan. i need to place the VM in another data vlan is it possible? if so could you give me a link or place information here.
View 2 RepliesI have two Catalyst 2960 Series (48 port) switches with the newest Cisco IOS installed. There is also a Cisco 2600 Series Router which I can't manage because it's ISP managed.
Now the problem is as follows. I'd like to create two VLANs, one in the IP range 192.168.0.xxx and the other in the 192.168.1.xxx. Now the router has a gateway IP address 192.168.1.1 .
Would it be possible to somehow connect these two VLANs with the router so that these 2 VLANs can't see each other but they can ofcourse both contact the router and exit on the internet?
I wanted to know about EHWIC 8-Port configuration? We create Data and Voice VLANs and assign 8 ports to the VLANs. So how do VLANS communicate with each other? We cannot make Gi0/1 as sub interfaces and assign the same subnet IP’s as of VLAN IP’s , it wont accept. On 1921 router Assume Gi0/0 we connect to MPLS WAN. What happens to Gi0/1 where do we connect this?

I have a a hardware server running a VM hosting virtual servers which are all on different VLANs. My challenge now is to configure the switchport that the server is connected to, to see all the VLANs needed by this VM. The VM has an IP that is used for managing the server VMs which is on a different VLAN also.
My switch is a 2960 switch and it is presently trunked from the core switch.
I am aware that private-vlans are not supported on edge switches like 2960 series - so my question is would it be possibel to ceate private vlans on say just the core switch which would be a 3570 or 4506 that supports private vlans and then just trunk these to the edge like normal vlans?what I need to achive is to have edge port not able to communicate to each other even across switches - which cannot be done using 'protected' port so need the private vlan feature?
View 1 Replies View RelatedOn a low-end switch like a 2960 the maximum VLANs is 255, as shown in the output of VTP status:
Maximum VLANs supported locally : 255
Number of existing VLANs : 245
When the VTP mode is changed to transparent, VLANs from the extended range can be added without increasing the number of existing VLANs - e.g. if I create VLANs 3000 - 4000 the number of existing VLANs is still listed as 245.
If MST is used to cut down on the number of spanning-tree instances - and assuming propagation of VLAN configuration via VTP is not required - is there any downside to using transparent-mode VTP to increase the number of available VLANs? It does feel like I'm cheating the maximum listed in the datasheet.

At one of my sites, I have a 100mbit TLS. For this connection to work properly, the port on my end needs to be setup for 100mbit, full duplex. When I connect the TLS to an interface on my Cisco 2821, configured at 100/full, it works perfectly. Now the confusing part, I'm trying to connect the TLS to a Catalyst 2960. I configure the necessary port for 100/full, and get 'notconnect' on that interface. I set the interface to auto/auto, and it negotiates at 100/half and causes collisions and packet loss.

I'm struggling with a configuration issue on the Cisco SG200-08P. We are using the Cisco SG200-08P on a mobile cart that will go from class room to class room that will have computer and cisco Voip phone plugged into it. The issue is that each of our closets are in differnt VLANS ( 1 voice and 1 data....lets say data vlan 20 and voice vlan 2025 for conversation) and that we route to each closet.It would be great if I could just create a generic data and voice vlan to dynamically pick up what the upstream switch has however, it seems that I've been unsuccessful in doing so. I can pass the data Vlan no probablem. The upstream switch port is set to access port and a switch port access voice vlan (these are 3750x switches) If the above is not possible I guess I will take what I can get. Should I just create data vlan 20 and voice vlan2025 on the Cisco SG200-08P and make a trunk port on the Cisco SG200-08P and a trunk on the 3750x? Is there an option on the Cisco SG200-08P to tag voice traffic?I'm also concerned with VTP and I did not see an area in the Cisco SG200-08P to set that as a client and transparent mode.

I have a problem to solve in our data center, see attached drawing. HW: Our core switches consists of two stacked C3750 with ip routing. What I want to do is probably simple but I haven't been able to figure out the best method.
VLAN10 and VLAN20 should not be able to communicate with each other. (ACLs?)VLAN10 will have it's own default route/firewall. Both VLAN10 and VLAN20 should be able to send server backups to server in VLAN30. All 3 V LANs come in on a trunk from a pair of stacked C2960-S. I need it to be able to scale if we have 50 VLANs for instance, hopefully without long complicated ACLs. I've been considering VRF's, PBR but can't decide what's the simplest solution to this problem. I have never done this before so I would prefer to start off on the right foot.

As per my attached diagram, I have three switches (Cat 3560-E and couple of Cat 2960-G)
Each PC is on different vlan
PC -1 on vlan 100
PC-2 on vlan 200
I need to connect PC-1 and PC-2 to the server. Server has no fixed vlan and can be changed.
Restrictions:
1) can’t change PCs vlan assignment.
2) can’t add 2nd NIC in the server.
I’ve tried private vlan but it requires separate physical ports for host and/or community vlan and somehow it did not work. I could be wrong Trunking using dot1q enabled on port 2 on all switches and connection works fine (server to PC-1 or server to PC-2) by enabling switchport access vlan 100 or switchport access vlan 200. However I need port 5 on switch-1 to respond to vlan 100 and 200.
I have a Ciso L3 switch with 4 VLANs and all host computer connected to rest of 8 cisco 2960 switch's:

1. For Restrict traffic from VLAN 10 to VLAN 20, I am using only one ACL is : Access-list 100 deny ip 192.168.10.0 0.0.0.255 192.168.20.0 0.0.0.255.\ What will happen in this scenerio if we talk about traffic from VLAN 20 to VLAN 10. Will it communicate or not ???

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.

View 2 Replies View RelatedI 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.
