I just inherited a network and feel like.I am missing something. We use ATT&T Opt-E-Man which limits the MAC address to 50 for the connection or you have to pay.Hence the routing VLAN is the only access across the two sites.I have a VoIP vendor who insists on using the same VLAN for all sites. Upon exam the VLAN is at the remote site but it does not work.

View 1 Replies View RelatedI've recently set up a PC-based IP PBX in our small business which uses a SIP Trunk for up to 3 simultaneous voice calls. Ports needed to operate include 5060 (SIP-UDP) and then a huge range of high-number UDP ports which I believe is for the 'media' or audio. Let's call the range UDP 49,152 to 64,512. I only know a little about the SIP protocol but my understanding is that each call will randomly use a few ports from this range across which will pass audio, Is there a need to have such a wide range of ports open? If my SIP trunk is only capable of 3 simultaneous calls then it seems only 9 or so of those open ports could get used at once. Could I not just open, say a range of 100 ports and be fine, thereby reducing the security risk?

View 1 Replies View RelatedMy first question is I have an access layer switch which is a single VLAN and I am trunking that VLAN to a distribution layer switch, I can ping the gateway on the distribution layer switch for THAT VLAN, But cannot ping the gateway address for the second VLAN I have on the distribution layer switch. I know it is simple, But I have forgotten and just need a push
Also I have a third VLAN set to route traffic not bound for those 2 VLANs out to a router is the statement "ip route 0.0.0.0 0.0.0.0 172.16.252.2" good enough and do I actually need to create a VLAN for that traffic? and if so, is an access switchport the best option?
I got a different scenario from one of my client.My client have two different branch offices and have 50Mbps point to point connectivity between them. All users in both braches using same series of IP pool ( 192.168.224.0/24) in both branches.Both branches he had only Cisco 2960S series switches only. And in both branches he is using IP cameras. He will monitor the assets by accessing IP cameras through the browser.His requirement is, he wants to prioritize the Video traffic( monitoring through the browser) over the normal data traffic.Note: He had a single VLAN only.
View 8 Replies View RelatedI've turned up a new layer 2 WAN link between two data centres and i'm having some trouble trying to logically figure out how things should be configured.As you can see from the diagram i've created, I have the link connected on port 13 on one switch and port 14 on the other. Both ports have an IP address assigned to them and they can both ping each other..
The problem comes when I need to add routes in order to get traffic flowing over the link.I added an IP address to switch 2 on the link interface (port 14) as: 192.168.4.10
I then added an IP address to switch 1 on the link interface (port 13) as:
192.168.1.10
192.168.2.10
When I tried to add 192.168.3.10, it said "192.168.3.0 overlaps with VLAN2626". This would be correct as Vlan 2626 has an IP address of 192.168.3.15.
However, if I remove the IP address from vlan 2626 and add 192.168.3.10 to vlan 2 (the link port VLAN), I would surely lose remote access to the switch. (I'm telnetting into the switch from a machine on vlan 2626).
I started to tinker with this by manually adding a route to a server in each location and seeing if I could get traffic to flow:
On server 1: route add 192.168.4.0 MASK 255.255.255.0 192.168.1.10 METRIC 1
On server 2: route add 192.168.1.0 MASK 255.255.255.0 192.168.4.10 METRIC 1
If I try to tracert 192.168.1.20 from server 2, the first hop is the default gateway instead of 192.168.4.10.
The ultimate goal is to add the static routes to the Layer 3 router/firewall, but before I do that, I need to be sure of what to add to that router (It's a manged firewall from the data centre, so I don't have access to it and I need to raise firewall change requests to get the work done, so want to ensure it's right first time.
I understand the vlans on the catalyst side of the house on 2900 to 6500 Catalyst switches.
This 7010 running nx-os 5.1(3) I did not setup, but have to manage it. Hasn't really been a proble till now.
My nexus 7010 has a Layer 2 only vlan 11. It is "Active" but the interface is "shutdown". Yet, it is passing traffic across the directly connected ports on the nexus 7010 and to other switches in my network. Vlan 11 is being set out via VTP to all my switches and things are running fine.
I need to create another L2 only Vlan. I can't seem to find any docs that indicate that a Layer2 vlan Interface on nx-os should be in "shutdown" mode as part of the setup. I do see in the docs where it has to be set "Active" as part of the process.
Is this the correct way to seutp a L2 only vlan on nex-os? Leave the interface in "shutdown" but make it "Active"?
Mystery Vlan 4 and 6
The mystery deepens. I have other L2 vlans ,Vlan4&6 that are NOT defined as "Interface Vlan4" in the nexus config, yet it is applied to GigE ports on the nexus and these Vlans 4/6is also being sent out VTP to all switches. Even weirder is that these vlans have names associated with the numbers. These are valid Vlans that were configured on the old 6509 before the Nexus was installed.
I have checked all switches, NONE are running in Server mode for VTP, all are in CLIENT. The nexus 7010 is the only device running in VTP Server mode.
I'm trying to set up VLANs in my network.So the first device after the internet cloud is my ISP modem/router. I don't really use the router part. The second device is my Linksys WRT54G router with DD-WRT firmware on it.Between the two, there is a subnet just for them. After the DD-WRT router, there is a subnet for my LAN.The third device is my netgear GS108T switch (with vlan support) to which almost all my computers are hooked up. One of those computers is my server that is domain controller and has the roles as shown in the image. What I would like to do is to create several virtual machines in Hyper-V. The trick is that I want to isolate them from the rest of my network. They should be able to access (and be accessed) from the internet but not the rest of my network. So my whole network should be in the same VLAN but each VM should be individually in separate VLANs.
1) I've allready created the VLANs on my Netgear Switch. I know my DD-WRT also has VLAN support. Do I need to create the same VLANs on that also?
2) How to configure the VLAN part of the Hyper-V server? (by the way, my server OS is Windows Server 2008 R2 with the hyper-v role, it's not the bare-metal hyper-v)Should my Virtual Switch be in VLAN 10 and my VMs in the other VLANs?Should the port (on the netgear switch) in which my server is connected, be in VLAN 10 (so that my server is accessible from every other computer in the network)?
Data link-ARP,RARP, presentation-SSL,TSL,ASCII,JPG, Session layer-ASP(apple talk session protocol),SCP are these correct?can your provide 2 new protocols for each with the long name?

View 7 Replies View Relatedin our environment we have a 6509E as a core switch which is connected to five 3750G installed in remote sites and are layer 3 routes. the routing protocol is ospf. i am just wondering if we could possbily create a vlan in the core switch and extended it to the remote site throug layer 3 connection. The reason we are thinking to do this we want to have a server redundancy if one of the server goes in the core site we can just turn on the server which is in the same vlan in the remote site so that we can limit the downtime .
View 4 Replies View RelatedI am new to VLANs although I generally understand the concept. I have a small office with 25 desktop/laptops and 15 VoIP phones connected with a SG200-50 switch and on Port 1 I have the Cisco SRP541W router for DHCP and Internet access. My goal is simple: 1) Segregate the VoIP phones (voice) from the computers (data) and 2) Prioritize the VoIP phones traffic.
I believe this can be accomplished by setting up a second VLAN and maybe a third (if the default should not be used) and then identifying those ports as Voice VLAN ports. I guess I just need to know how to flag each interface and each port so that they all can talk to the router on Port 1 yet the voice and data will be in different broadcast domains. Also, do I need a management VLAN??
Is this setup correct? VLAN 1 - default (data) Port 1 (Trunk) (Tagged)Port 2 - 30 (Access) (Untagged)VLAN 2 - voice Port 1 (Trunk) (Tagged)Port 31 - 48 (Access) (Untagged) What should the interface settings be on each port (General, Access or Trunk)? What should the port VLAN membership be on each port (Tagged or Untagged)??

View 4 Replies View Relatedhow to configure vlan tag on routed layer 3 interface in cisco 3945 device?
View 2 Replies View RelatedI have a SG300-28P switch. I just read in the Administration Guide that, when in Layer 3 mode, the switch doesn't support MAC-based VLAN or Dynamic VLAN Assignment.
So, in order to assign a client to a VLAN based on their MAC or based on the response of a RADIUS server, we have to disable layer 3 features. Without layer 3 switching, the switch is unable to act as a default gateway and forward packets between VLANs. As a result, the VLANs can't communicate in any way, or access the internet, unless a separate router is connected to every VLAN. Right? Doesn't this limitation significantly reduce the usefulness of the DVA feature?

Switches are
WS-C3750G-24TS-E1U
WS-C3750V2-24PS-S
I have a Cisco SG 300-20 as the core switch, layer 3. It is 192.168.4.6 on VLAN1 and 192.168.5.1 for VLAN2 (VOIP). All the ports are set in trunk mode. DHCP relay is setup on this switch.
The phones connected into a layer 2, Catalyst 2960-S switch. All ports are set in trunk mode. Default gateway on it is set to 192.168.5.1.
DHCP for both VLANs is provided by a Windows Server 2008 R2 server (the relay IP 192.168.4.15).
There is also an ASA 5510 in the mix which is 192.168.4.1. It has a route added to it for the 192.168.5.0 network to go to the SG 300 (192.168.5.1).
Just the two switches can ping each other on the 192.168.5.x network when I "add vlan 2" to the trunk port that is connected between the SG 300 and the 2960. The phones don't get DHCP on the 2960 switch. And I cannot ping 192.168.5.x from the ASA or anything else on the 192.168.4.x network.
After a bit of reading on intra-vlan routing for the SG 300 switch, I am thinking the SG 300 has to be the "center" of things so I need to make it 192.168.4.1 to be the gateway for both VLANs and change the ASA to 192.168.4.2 for VLAN1, etc. And I really can't do asymmetric routing with this switch.
I have a 3550 l3 switch configured as follows:
vlan 10 ports 1-10
vlan 21 ports 11-20
vlan 30 port 21-30
vlan 40 ports 31-40
default vlan should be vlan 21
I have the servers, switch and router connected to vlan 21. Vlan 21 works great I can browse the internet, but I cannot ping any other vlans. router is connected to fa0/19

3) just have the management address as the peer ip's.
