Cisco Switching/Routing :: Catalyst 6506 Vlan-based Qos Configuration?
Feb 12, 2012
I was unable to configure vlan-based qos on Cisco IOS Software, s72033_rp Software (s72033_rp-IPSERVICESK9-M), Version 12.2(33)SXH6, RELEASE SOFTWARE (fc1) Seems to me my configuration is not working. Here is the output of the interface:
sh int G1/6 | i rate
Queueing strategy: fifo
30 second input rate 25231000 bits/sec, 4282 packets/sec
30 second output rate 46940000 bits/sec, 9257 packets/sec
And here is my configuration:
interface Vlan3
ip address 192.168.1.1 255.255.252.0
service-policy input TEST_IN_PMAP
service-policy output TEST_OUT_PMAP
[code]....
Why I can't see matches in ACLs? I've double checked the direction and seems to me it is correct. I can't see matches even I configure something like this:
10 permit ip host 192.168.1.168 any
20 permit ip any host 192.168.1.168
Why my output rate is higher than 30M? Is it bacause there is no matching traffic here in ACLs? I'm absolutely shure that this host with such ip connected to this interface:
#sh arp | i 192.168.1.168
Internet 192.168.1.168 0 feed.beef.f00d ARPA Vlan3
#sh mac address-table | i feed.beef.f00d
* 3 feed.beef.f00d dynamic Yes 0 Gi1/6

I have got a catalyst cisco 2960G series switch and via this switch I want to creat serveral vlans. I am getting a dhcp IP from a router and I want to setup my own vlan networks.
I plugged in the Ethernet cable that came from the dhcp router to port 16 of the cisco switch and configured the ports 1,2 and 3 for vlan 1, 2 and 3
the dhcp router has given me this IP 192.168.10.158 defautl gateway is : 192.168.10.1
when I plug in a PC to port 1 or 2 of the cisco switch I still receiving the IP from range 192.168.10.* but not from the range that I configured for the vlan 1 or 2.
Below is my startup configuration:
no file verify auto
spanning-tree mode pvst
spanning-tree extend system-id

I am going to creat VLANs very 1st time therefore for test purpose I have following simple scnerio.I have created 2 VLANs , VLAN2 and VLAN3 on Cisco Catalyst 2960 series switch. Ports 1-12 is assigned to VLAN2 and Ports 13-24 are assiged to VLAN3. Now I have configured DHCP on Microsoft Server 2003 defining 2 scopes with following configurations.
Scope 1 for VLAN 2--- Range is 172.16.0.17 to 172.16.0.30 with subnet mask=255.255.255.240 . Server IP address 172.16.0.17
( Note: Address 172.16.0.17 is excluded from dhcp server Scope 1 and give to the MS server itself)
Scope 2 for VLAN 3----Range is 172.16.0.33 to 172.16.0.46 with subnet mask=255.255.255.240 .
Now in Cisco 2960 series switches, under Vlan 2 and Vlan 3, I have following configurations...
interface Vlan2
ip address 172.16.0.30 255.255.255.240
ip helper-address 172.16.0.17
interface Vlan3
ip address 172.16.0.46 255.255.255.240
ip helper-address 172.16.0.17
Now the problem is when i connect a client computer to any port from 1-12, It gets correct IP address from Scope 1 but when I connect a computer to any port from 13-24, it does not get the ip address.
Further I want to do inter VLAN comunication as well for that purpose i Have an ISR 2900 series router. What further configuration i will have to do on router for inter vlan communication.

i want to know if 1port of the 16 10Gbase-t Module (WS-X6716-10T-3C) for the Catalyst 6500E Series, can be connected to a 1Gbase Port of a 2900 ISR Routers, are they gonig to work at 1Gbps or, simply, they are not compatible?
If it is true, can i create a 4ports etherchannel between them? of course using the 16 1Gbase-T switch module on the Router.

I have two Catalyst 6506 in VSS mode with VS-S720-10G running 12.2(33)SXI1 IP SERVICES.I have two firewalls that communicate on to the other through a dedicated VLAN created on Catalyst 6506.
One firewall is able to ping the other one on this dedicated VLAN but if I send multicast traffic from firewall-1 I didn't receive it on firewall-2.I found a bug related to multicast issues on Cisco WS-C6509-E with VS-S720-10G. The bug ID is CSCtc59038.

I just bought a Catalyst 2960S to test out the feature "Port-Based Address Allocation" which is required for our factory. I followed the instruction from Cisco IOS and did all the steps but I could not get it to work, my network client did not received the expected IP address that I configured.

I've one Cisco 3750G-12S with ip routing enable, the swtich is with IP Service firmware, with PRR support.Currently set my default static route 0.0.0.0 0.0.0.0 10.1.18.71 to my Firewall A Currently all of the VLAN for will be routed to 10.1.18.71
I've created a new VLAN 2 for my 10.1.2.0/24 network with the VLAN interface 2 ip address 10.1.2.10, my intention is to route 10.1.2.0/24 traffic to my 10.1.2.1 by creating the access list and route-map.
I've configure my test pc with a static ip and my gateway pointing to 10.1.2.10 (VLAN 2 gateway) , i'm not able to route to 10.1.2.1.

I have a network with a Catalyst 3750 as the main switch and then some Catalyst 2960 switches that are plugged in to that. I have a server running windows server 2008 with a couple of virtual machines running in Hyper-V. I created 4 VLANS listed below and gave the 3750 the following IP Address.I would like the 3750 to only be configurable from VLAN 40 but currently every VLAN can connect to it, I noticed in the standard web page settings there was a setting for "Management VLAN" but it was set to 1 and would not let me change it, I kinda assumed that was for the management port in the back.-Now the tricky part, I was trying to set up routing between the VLANs and so far I have only been able to get a sort of "all or nothing" routing to work. I can turn IP routing on and add two or more VLANs to the routing and it works fine. But what I was hoping to do is create a couple of "junction vlans" that would only route to one or two other vlans. For instance, I wanted to create a VLAN 100 that routed to VLAN 20 and 30 but nothing else. I also want to route VLAN 1 just to VLAN 30, and so on. I am able to do each one of the cases but only one, it seems like the switch only supports one "routing table" am I missing something or is this just a limitation of the switch?

I have a network with several catalyst 2960 switches and one catalyst 3750. I have created two VLAN and set up the proper routing and everything is working fine there. I have a client/server application that used multicast in the initial start up for the client to determine available servers, the issue is one of my clients is on a different VLAN then the server. I am able to route the multicast using MVR as long as both the server and the client are plugged into the 3750 by creating a static route, making the server a source port and the client a receive port. Unfortunately I need the client and the server plugged in to different 2960s. My question is how do I establish multicast routing between the two and perferably do it dynamically (always route multicast traffic from one VLAN to another).

I have been looking into this for a while and I can't seem to figure out why my 2nd vlan is not able to connect properly to the net.
My switch has 12 ports where my devices connects directly, they are all on Vlan 1 and they all work perfectly. on Port 12 I have a dlink router that is connected to a cable modem. the dlink router has an Ip address of 192.168.0.20
I created a second vlan (vlan2) and enabled dhcp relay on it. then I assigned port 9 on the switch to (vlan2)my laptop which is connected to port 9 seems to get an ip address fine and able to ping only some devices on my network (vlan1) and is not able to go out to the internet. I think it has to do with the routes. [code]

I have 3 VLANs here that need to be on the same network segment. They are going to be used by our Wi-Fi network (with Aironet APs), bound to 3 different SSIDs (as Aironet APs doesnt allow multiple SSID per VLAN), each one with a different authentication method and server.Is there a way to bridge those VLANs together with a Catalyst 3750 switch? I tryed configuring an IP address on one of the VLAN interfaces, then configuring a bridge with the vlan-bridge protocol (Catalyst 3750 doesnt have the "ieee" bridge protocol type) and put all 3 VLAN interfaces on the same bridge-group, but it didnt work (even with "bridge x route ip").I also tryed configuring IRB bridging, with the 3 VLAN interfaces on the same bridge-group and an IP address on the BVI interface (the way I used to do with old 2600 routers). Same result.(actually, I didint test to see if the interfaces are actually being "bridged", but I see neither of them can reach the router)

I have installed a Catalyst 2960-S and a 3750-X-12S and I am trying to setup a VLAN 51 for some VoIP phones. I have added the VLAN as an interface on both switches, but the 3750 is not showing VLAN 51 as active when i do a show vlan. Also, it omitts showing Gi1/0/1 & Gi1/0/3 which are uplinks to 2960-S switches plugged in and working on VLAN1.

I'm configuring two etherchannel groups (2 ports in each) on a 3560 switch. I need to trunk multiple vlans over each channel group.
I created the vlan trunks and allowed vlans on each physical interface. I notice that I can also configure the vlan trunks on the port-channel interfaces that were created. Should I configure them under those interfaces, or leave them on the physical interfaces? Relevant config is below:
interface Port-channel1
!
interface Port-channel2

My architecture is the same as show on the link with some difference.I use the router 1841 for inetrnet connexion instead of 7200VXR, this router 1841 is connected on the catalyst 3750 port G1/0/1.I use catalyst 2960 instead of catalyst 2950 or 2948.I use ASA 5510 for conexion on remote branche(I have 5 remote site), This ASA is connected on the catalyst 3750 port G1/0/37
Result of the test:
-I can ping devices in the same Vlans
-I can ping devices in different VLANs
-I can ping all device from the catalyst 3750
I cannot ping the router 1841 or ASA 5510 from the any devices (computer)The gateway of each computer is the correpondant VLAN IP address configured on the catalyst 3750.Why I cannot ping the router 1841 or ASA 5510 from the any devices (computer)

I am attempting to create a mass upgrade server for some of our more standardized equipment since our vender cannot upgrade them pre-shipping for us, we've got to do them on our own. This means using a terribly organized wizard written in what appears to be Java...
I have an aversion to Windows and felt that I could accomplish the same thing using expect scripts and a Gentoo Linux server; now all I need is to set my Cisco 3550 (c3550-ipservicesk9-mz.122-44.SE6.bin) to have each port on it's own VLAN, except for fa0/1 which will be a trunk port to communicate with all ports as well as the server.

I am trying to write an extended ACL for the voice vlan.My scenario is the following:I have two PBXs with two Catalyst 4505 L3 switches.The C4505 are connected trough a trunk link.I have a VTP domain configured.
Voice VLANs are Vlan 100 and Vlan 101 with networks 10.2.0.0/16 and 10.4.0.0/16 Voip telephones are communicating between them self and everything is working fine.I want to secure both voice VLANs with an ACL to allow only couple of IPs to administer the phones.The PCs are connected trough a integrated switch via VOIP telephone.Here is the sample configuration of the dhcp pool for the PC VLAN:
ip dhcp pool PCs
network 10.1.0.0 255.255.0.0
default-router 10.1.1.1
dns-server 10.10.10.1
option 43 hex 010a.5369.656d.656e.7300.0000.0204.0000.0064.0000.0000.00ff
I had to implement the 43 hex option because the PCs did not get the ip from the DHCP because of the vendor specific information.The thing that worries me is will the DHCP forward the ACKs for the PCs if I implement this test ACL:
ip access-list extended VLAN100
permit ip 10.2.0.0 0.0.255.255 10.4.0.0 0.0.255.255
permit ip 10.4.0.0 0.0.255.255 10.2.0.0 0.0.255.255
permit ip 192.168.2.0 0.0.0.255 10.2.0.0 0.0.255.255
permit ip 192.168.2.0 0.0.0.255 10.4.0.0 0.0.255.255
permit udp host 0.0.0.0 eq bootpc host 255.255.255.255 eq bootps (this I am not sure do I need)
permit udp host 255.255.255.255 eq bootps host 0.0.0.0 eq bootpc (also this)
deny ip any any
I only want to allow the network 192.168.2.0/24 and maybe some other hosts to access the web based http gui to adiminister the IP phones.All PCs are connected trough the VOIP terminals. I do not want to deny the traffic to PCs.

I am struggling with a CE520 and its smartports stuff.I have configured the following vlans :
1- data
100 - phones
I need to bring those vlans (both of them) to a Cisco 800 router. The port of the 800 router is already configured as trunk and accepts vlan 1 and 100.The cisco 800 has both vlan 1 and 100 configured with 2 ips on different subnets, and ip routing is enable (to route between two vlans). Also, no access lists are configured.I have configured one port in the switch as role "router" and connected to the router. The other ports are all configured as phone-desktop (phone vlan 100 desktop vlan 1).If I connect a phone and manually configure an ip (the phone gets automatically vlan 100), and try to ping the phone from the router, it doesnt respond. Alse vlan 100 is protocol down.I am guessing what s the right configuration as the link between the switch and the router should be a trunk link for 1 and 100 vlans, but it looks like is transporting only vlan 1.Also changing the port role to "other" when you can specify the native vlan and another vlan, the switch doesnt accept vlan 100 as additional vlan on that link.
