Cisco Switching/Routing :: 2960S - IPTV VLAN In Trunk QOS
Sep 22, 2012
I need to set QOS in our new network. We have connected 2 cities together with 700Mbit leased line. On each side we have Catalyst 2960S switches and between them is TRUNK for VLAN 10 and Vlan 20.Vlan 10 is for IPTV (fixed 400 Mb/s for CATV)Vlan 20 is for Internet (rest).Sometimes is happening that Vlan 20 takes more than 400 Mb/s for a few seconds and in this situation we have problems with CATV.Is there any way to make a guaranteed bandwidth 410 Mb/s for CAT - VLAN 10 on this swithces?

we have Catalysts 2960S for switching in our Wireless high capacity backbone network. As agregation switch we are using 3560x.
I just need to know, if are these 2960S good solution for igmp snooping for whole IPTV stream. It put only a range from backbone and put out on another port. But just specified multicast addresses.
Imput will be 239.128.0.10 to 239.128.0.20 on Gi 0/1,Output wil be 239.128.0.10 - 15 on Gi 0/24
IPTV will be separated on different VLAN for eg VLAN 20,Is needed any priorization configured od switches?,The capacity for IPTV is around 500 mbps

i need to solves this little problem on 2960S lan BASE but i dont know if it is possible.
Uplink port config for gi 1/0/28 is:
switchport mode trunk
switchport trunk alloved vlan 10,11
but on interface gi 1/0/1 i want to have data from vlan 10 tagged as VLAN 20.
At this time i have solved this issue very primitively
I have set up gi 1/0/2 as int mode acces, acces vlan 20 and i have connected gi 1/0/2 with gi 1/0/3 with eth cable. int gi 1/0/3 is switchpor mode acces, switchport acces vlan 10

I have 2 hosts, 1 plugged in fa 0/21 in VLAN 101 and another in fa 0/22 in VLAN 101 on our L2 Cisco 2960. If I try and transfer files from either host the gig 0/1 trunk port on the 2960 leading tot he 3750 fa 0/1 port hits 100mb (using a real time bandwidth monitor tool), but why? This VLAN is on the same switch, why does it go one way up the trunk to the L3 3750 switch? The L3 3750 is the VTP server and the 2960 is a client. I would of thought the traffic stays local. The 2 hosts don't even have a gateway set.To sum up the typology the 2960 and 3750 are trunked using a single cable. The 3750 hangs of a ASA firewall using SVIs.Here is whatthe traffic looks like when copying a file between hosts (2gb file).

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.

I have hybrid network in which I want to configure VLAN on Cisco 2960 S switch. I have unmanged switch where my DHCP server and other servers are connected. Now I created two VLANs on cisco 2960S and they don't talk each other, but as soon as I connect unmanaged switch to 2960S switch, both VLANs start communicating which I don't want. I want to listen server traffic from unmanaged switch from both VLANs but simultaneously I don't want to communication between two VLANs.

I have a 2960 switch connected to another. The I need to verify that vlan0010 on one switch is forwarding tagged traffic between the other switch it is hooked up to through the Gi0/1 port. How do I verify this? I have a server that's multihomed (Broadcom) on the other side an it is supposed to be on this vlan with one of it's network interfaces. We had a pwer outage and now it cannot communicate on this vlan. However, everything else on the vlan can reach all the other nodes accept this server in the front of my building. All the devices in the same room are linked to the same switch which has one port (fa0/17) on vlan0010 and can ping eachother just fine. The server is hooked to port 24 on my server room switch and Gigabit port one goes to a fiber converter all the way to the back. It then gets converted from fiber to cat5e again and links into the switch (2960) in the backroom.

Need to limit the amount of bandwidth a specific VLAN can use on a 802.1q trunk port. Situation is that we have a pair of Catalyst 4506 switches which have 802.1q trunk ports into a Checkpoint Firewall, this in turn is connected to a managed WAN router (to which I can't apply a QoS policy).If the 4506 was routing the traffic it would be easy to setup a class-map to match the IP traffic and then QoS the traffic, but the VLAN in question is trunked directly into the firewall (no L3/IP presence on the 4506 next hop for all clients on this VLAN is the firewall).What I need to do is restrict any traffic from this specific VLAN to 10Mbps on the uplink to the Checkpoint Firewall so it cannot impact the onward WAN.

Currently we have a 6513 core (running IOS and doing limited routing) with VLAN Trunking to about a dozen 3560 edge switches, with various VLANs going to each of the edge switches. All works well. We are downsizing and replacing the 6513 core with a 3750G stack. We have the stack up and running in the lab, and want to slowly (as we move floors) migrate all of the edge switching to the 3750 stack.
The plan is to connect the 3750 stack to the 6513, then slowly migrate the edge switches to the stack (from the 6513). I would like to put in place 4 x 1GB trunk links between the 6513 and the 3750 stack before I start moving edge switches to ensure adequate bandwidth. Once all of the edge switches are on the new 3750 stack, I will start to decommission the 6513.
What is the best way to configure the links between the cores (old 6513 and new 3750 stack)? I can easily get the edge switches configured to the 3750, but am worried about the core links. I really want to avoid having to perform an all-at-once cutover of the cores. Another question is when do I try and migrate the VTP server role from the 6513 to the 3750 stack? I could simply make everything transparent, and ditch server-based VTP, as we rarely change or creat VLANs.

We are trying to setup a new configuration with 2960S as access switchs and a 4507 as a core switch.I want to protect the management IP VLAN of the swich using vrf on the 4507 so we :
SHUT VLAN 1 on every switch (2960 + 4507)
CREATE A NEW VLAN 289 (management vlan) -> IP network : 10.32.126.192/26
L3 VLAN on every switch
VLAN 289 in the VRF XXX on the 4507
create tunk between the switch and the 4507 :
switch mode trunk allowed vlan 200-230
sw trunk native vlan 289
so with this configuration on the 2960 the vlan 289 is UP/DOWN and UP/UP on the 4507 I can access to the 4507 using the IP in the VLAN 289 but i cannot access to the 2960 behind the 4507 CDP connectivity is ok?

Have multiple Catalyst 2960S switches, Cisco 2911 router and ASA 5510 firewall.
On the router have subinterfaces created for the VLAN's Int FA0.0/41 for wirless VLAN setup with IP 10.10.41.100 Int FA0.0/60 for new Voice VLAN setup with IP 10.10.60.100 Internal network is 10.10.10.0/24 and LAN IP of router is 10.10.10.100 Have default route setup to push traffic from the router to the firewall ip route 0.0.0.0 0.0.0.0 10.10.10.251
On the firewall have added the new VLAN 10 (10.10.60.0) to the network object-group Have configured route inside command route 10.10.60.0 255.255.255.0 10.10.10.100 1 Have also added the NAT command nat (inside) 1 10.10.60.0 255.255.255.0
On the 2960 I have my laptop connected to port 45 and I have it configured as follows switchport mode access switchport access vlan 10
I assign my computer a static IP address of 10.10.60.84/255.255.255.0/10.10.60.100 with 10.10.10.11 as DNS server. When I do this, I can ping anything on the 10.10.60.0 network, I can ping anythign on the LAN 10.10.10.0 network. I am able to connect MSN messenger, I am able to do NSLOOKUP and get outside IP addresses to resolve. I am unable to browse the Internet though. I am not sure where the problem is at though. It doesn't make sense to me, as it is setup the same way as VLAN 41 which is the wireless network, and when users connect to that, they get out to the Internet with no issues.

I have several closets with Cisco 3560 on the edge that I'd like to change the vlan that's used for the management vlan on each. In the core I have a Cisco 6509 with Sup720's.
I'd like to do this by changing the native vlan on the trunk port on the core 6509 interface that connects to the 3560. and leave the management vlan on the 3560 as vlan 1.
Seems trivial but what I tried didn't work and I didn't have the window to troubleshoot. I'll paste the simplified configs for the interfaces below

6509 configs:

I need adding a vlan to the trunks bundled in port channel. I know how to add v lans to a port channel with Cisco IOS but with CAT OS.
I have 2 ports bundled to form ether channel in switch which is running CAT OS. There are already few v lans allowed in the trunk of each interface. now I need to add one more v lan.
For Example:-
v lan 135 needs to be added in addition to the existing v lans.
clear trunk1/2 1-112,115,117-134,136-4094
set trunk 1/2 on dot1q 113-114,116,135
and similarly on the 2nd interface
so if I add vlan135 to the trunk one after another will it cause any service disruption?

I have a 3750 as a core and have a series of HP Procurve switches that are daisy chained using one port. I have two vlans on the port now (6 &9) and everything works fine, all switches communicate and end devices on the switches are also talking. There is a requirement to add a device towards the end of the chain which requires it to connect using Vlan1. Once I add Vlan1 to the port onthe 3750 I lose connectivity to all the HP switches.

Current Situation:We are able to reach server IP -10.203.206.40 from our 4948 switch vlan 10.30.1.0/24 through the Layer 3 interface between 4506 and 4948.
Requirements
==========
1) Now we would like to add one more L3 interface between 4506 & 4948 for redundancy purpose.
2) Make available Vlan 540 in 4948 from 4506... need to create two trunk links between 4506 & 4948 and allow vlan 540.

Has anything changed in the way of defaults for creating a trunk port and spanning-tree between a 3750x and the newer 2960s? I have one of each I just took out of the box and applied my standard switch configuration template but I cannot get my VLANs that are configured on my 3750X to appear on the 2960S. I find nothing that is blocking and everything seems to be forwarding and I am running out of things to check.

Any way to test in a lab what would happen if a tech mistakingly added "switchport voice vlan XX" to a trunk port? I am try to do some RCA on an issue and this has been identified as a possible cause by one of my techs.
The config is Switch1------Switch2--------Switch3 Each interswitch connection is configured as a dot1q trunk with all vlans allowed. The link between switch2 and 3 is where switchport voice vlan 10 was added. Switch1 is a 3750 and 2/3 are 3560's.

I'm not sure if I'm missing something basic here however i though that I'd ask the question. I recieved a request from a client who is trying to seperate traffic out of a IBM P780 - one set of VIO servers/clients (Prod) is tagged with vlan x going out LAG 1 and another set of VIO server/clients (Test) is tagged with vlan y and z going out LAG 2. The problem is that the management subnet for these devices is on one subnet.
The infrastructure is the host device is trunked via LACP etherchannel to Nexus 2148TP(5010) which than connects to the distribution layer being a Catalyst 6504 VSS. I have tried many things today, however I feel that the correct solution to get this working is to use an Isolated trunk (as the host device does not have private vlan functionality) even though there is no requirement for hosts to be segregated. I have configured:
1. Private vlan mapping on the SVI;
2. Primary vlan and association, and isolated vlan on Distribution (6504 VSS) and Access Layer (5010/2148)
3. All Vlans are trunked between switches
4. Private vlan isolated trunk and host mappings on the port-channel interface to the host (P780).
I haven't had any luck. What I am seeing is as soon as I configure the Primary vlan on the Nexus 5010 (v5.2) (vlan y | private-vlan primary), this vlan (y) does not forward on any trunk on the Nexus 5010 switch, even without any other private vlan configuration. I believe this may be the cause to most of the issues I am having. Has any one else experienced this behaviour. Also, I haven't had a lot of experience with Private Vlans so I might be missing some fundamentals with this configuration.

I am looking into the possibility of using private vlan's for some dmz implementations however I do have what may be some very rudimentary questions. It seems straightforward how to configure the primary/secondary vlan configuration as well as associating them. However in my case I would be looking to configure the PVLAN on a 6500-vss platform acting as the router while all of the hosts which I would desire to have in the isolated vlan would be spread out across a number of older Cisco switches which only support "protected port" setup or Procurve switches all of which I do not have budget to replace with something newer. So in my scenario I would have a 6500 connected by trunk to multiple switches which only support a protected port setup such as a Procurve (top of rack) or a Cisco 2950. As the Procurve or 2950 would not support Private VLAN setup, do I then just configure the secondary vlan to be allowed across the trunk from the 6500, configure that vlan on the Procurve or 2950 (as vtp will not foward the info for the secondary vlan) and assign that vlan to the host port as well as setting it as a protected port and this will communicate just fine across the trunk to the router as well as stopping the protected port in top of rack switch 1 from being able to communicate to a protected port in top of rack 2,3,etc? If the above scenario is what needs to be done, do I just use a regular trunk or do I have to use a PVLAN trunk?

we recently aquired a managed services job and have to do a overhaul of the vlan configs and have a whole dozen WC2948G's trunk between a set of ports as well as trunk out a LAG channel setup to non cisco equipment. the deal is the lacp-channel works properly on both ends but no routing of vlans between ports and between the lag trunk are working.
theres alot of settings in the config and im planning on clearing it and starting from scratch but before i do i want to know where my problem lies.

I have recently split the voice vlan (10) from the data network (1), and am wondering why my catalysts and router do not require an interface Vlan10 statement. In the past I used OpenBSD boxes to do the routing, and I first needed to configure vlan 10 on the interface before I could get inter-vlan communication to work. With these Cisco devices it works, and I am wondering if it is because of VTP, for the fact that the ports maybe just pass all traffic, or is there some other explanation? Below is the setup, and firmware is up-to-date on all of the devices.
When I plug a phone into the POE SGE, the phone turns on, obtains an address on the proper subnet, and conversations are clear (whereas without the ip nat inside on the new subnet the calls had a lot of static). Possibly the reason that it works is because the phones properly create the tcp/ip packet, and it hops over the trunks and creates the states so that traffic routes back properly. I will install wireshark to see exactly what is going on, but is there a simple explanation that I am overlooking?

I currently have Cisco MWR2941's that i would like to configure the TRUNKs on then push them over a 5520 VPN ( IPSEC Tunnel ) to a 5510. on the other side of the 5510 i will have another MWR2941 to recieve the trunk.
how to configure this trunk or some configuration ideas?
