The field engineer has a stand alone 24 port 2900 series switch that he has different equipment connected to and are segmented using VLANs. So for example, he's got ports 1-4 assigned to VLAN 10, 5-12 assigned to VLAN 20, 13-19 assigned to VLAN 30 and 20-24 assigned to VLAN 40. He would like all the gear on VLAN 30 to have the ablity to talk to all of the other VLANS, but VLAN 40 should not be allowed to talk with any other VLAN. Trunking would do no good here since the switch isn't connected to anything and you can only assign one VLAN per port.
Is there a way to do this within the stand alone switch? The only possible way I could think of would be to ensure that each VLAN has an assigned IP number (subnet) and doing this through access lists.
I would like to know if it is possible to assign a 3rd IP address to my end user vlan. Basically the 45xx acts as my end user gateway and has been confirgured as below
interface VlanXX description Main Vlan ip address 2.X.X.X 255.255.255.0 secondary ip address 1.X.X.X 255.255.252.0
[Code].....
Here, due to IP address exhaustion in my end-user network, i want to add one more subnet X.X.X.X/22 to my network and assign one IP more from this range to the above vlan to act as the gateway IP.
I have a small network that i want to setup, i have 1 2900 router and i'd like to create subinterfaces for the internal. but more importantly i'd like to have the dsl modems connected to the router with traffic from one subinterface going through one modem and traffic from the other going through the other.
I have a 2900 router at branch office. This router has a 4 port switch card and two gigabyte ports. The gigabyte port is use for wan connection and the 4 port switch card is use for lan connection. I have two separate networks on my lan side. (network 1 and network 2)
I have assigned port 0,1 of the switch card to vlan1 for network 1 Ports 2,3 of the switch card is assigned vlan 20 for network 2
My problem is I would like to applied a bandwidth restriction for all data coming out from vlan20 capping same to 384 kb.
Note I do not want use QOS because this will only kickin when saturation occurs,
I'm new to networking and was looking for some assistance. First off im using packet tracer to diagram my senario as I will be receiving my equipment next week to deploy.
Hardware to be used:
1. 2 catalyst 3560 switches 2. all connect to a sonic wall router
I have two companies that work in the same office space. I need to keep these companies seperate on their own vlan. They will however need to share the phone system.(Packet tracer file uploaded to give those who have the time to see what I put together.) [code]
Had an odd issue that started up last few days.. Have a port on a cisco 2912 XL that keeps dropping (drops all packets) on a certain VLAN, but still passes others. Spanning-tree for that vlan says all ports are in forwarding status. VTP says that VLAN is still active.
This network is a little strange... 2924XL -> MotoPTP -> 2912XL -> Moto Canopy Array -> Some sites with cisco, some without all feed through canopy controller switch to single port (fa0/8) on 2912.
Getting a few of these on terminal monitoring, %RTD-1-ADDR_FLAP: FastEthernet0/8 relearning 5 addrs per min... Sometimes this is fa0/8, fa0/10, or fa0/1.
I'm thinking the switch has just gone nuts, cause fa0/1 is direct connected to a router used for VLAN1. fa0/8 is connected to a dumb switch on a canopy CMM as a trunk which i enabled bpdufilter on because of some spanning tree issues on VLAN1. fa0/10 is connected to canopy PTP back to the 2924 as a trunk. VLAN69s router is off the 2924. So there aren't really any possible alternate packet paths to this switch from another switch.
I also setup SPAN and captured all packets from fa0/8 and fa0/10 (seperately) and never seen packet storms of any kind on either VLAN1 or VLAN69.Further testing with debug, nothing on spanning tree, nothing on vtp, but on ethernet-controller addr I got some interesting results showing one mac moving from fa0/1 to fa0/8 and back to fa0/1 but it never moves, its the routers mac that is connected directly to fa0/1. Same with some macs on the other side of the PTP link saying they are bouncing from fa0/10 to fa0/8 and back to fa0/10 which isn't possible
I have a Cisco WS-C2960S-48TD-L with 12.2(55)SE2.This is a standalone switch, not in stack, and with no order it reboots itself looking for a new master election. On logging i have nothing, but connected with console cable i see the following after 2 minutes of not showing anything:
Waiting for Stack Master Election... ... The switch reboots and: ... *Mar 1 00:00:12.289: Read env variable - LICENSE_BOOT_LEVEL =
[URL]
After searching online i have no seeing nothing about disable the feature of the stack so i configure the priority for the "switch 1" to 15 and configure it the switches 2, 3 and 4 to no provision, although this switches don´t exist:
SW_ACCESS(config)#switch 1 priority 15 Changing the Switch Priority of Switch Number 1 to 15 Do you want to continue?[confirm] New Priority has been set successfully
[URL]
With this new configuration the switch has rebooted again.Why on a standalone switch the stack is rebooting my system?Is it any feature to disable the stack?
Configured Layer 3 portchannel from 6500VSS enabled switch to two different 6500 standalone switch. Configured first ip on VSS switch, second ip on standalone switch1 and third IP on standalone switch2. My question is
1. Will the portchannel be up? 2. If port channel is up, will I able to ping the connected IP's.
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 have a LIII Switch Cisco 3750x ,with diffrent Vlans , Some users are in Vlan 102 (10.10.2.0) and Some Users are in Vlan1 (10.10.1.0) , now i want to restrict the Vlan102 users to access Vlan1 , i am pasting my configuration below , how to create a access list .
interface Vlan1 ip address 10.10.1.36 255.255.255.0 ip helper-address 10.10.1.36
I have two networks at two sites with a dot1q trunk between the two L3 switches at both sites (no routers involved)
SITE A - Cisco 3750 L3 - VLAN ID 50 10.10.50.0/24
SITE B - Cisco 3750 L3 - VLAN ID 50 10.20.50.0/24
I would like to extend the SITE A VLAN to SITE B so that I can move hosts from SITE A to SITE B without needing to change their IP address but the vlan ID is already in use. Obviously the easy solution is to change the VLAN ID for one or other of the sites but both sites contain hosts that run 24/7. Is there a way to join two VLANs with different IDs together.So for example I create a new VLAN 60 at SITE B and associate it with VLAN 50 at SITE A.
I have came across this topic, and I am wondering if this images can be uploaded to any 2900 series switches or not, and if this will work as access port for more than vlans. URL...
I just purchased a used Catalyst 2900 XL switch and have not been succesful in connecting to the console via minicom 2.5 running on Ubuntu 12.04 or 11.10, I don’t even get junk charecters in the terminal or echo on input. The switch passes POST according to the LEDs on the front and the network ports are fucntional for switching purpouses.
I’m using a Prolific PL2303 USB-Serial adapter, which works with minicom to console into another device. I’ve tried every baud rate available and tried combonations of hardware flow control, software flow control, and niether.I’ve tested the pinout of the console cable and all pins map correctly according to Cisco spec.I’ve also tried Cutecom, putty, and screen. I have not tried HyperTerminal because I do not use windows.Is it possible that the previous owner disabled console access? Do I need to reboot the switch each time I test a different baud rate?
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?
We have two Cisco 5505 firewalls connecting to two ISP's . The two internal LAN's on the firewalls are 192.168.184.0/24 & 192.168.186.0/24. We also have a Cisco C3560x layer3 switch with vlan interfaces 184.3 & 186.3. We have two DGS-3100 Dlink layer 2 switches connecting our users to the Layer 3. Ip routing is enabled for intervlan communication & I can reach the Switch interfaces & firewall gateways from machines on both on the vlans.We have pbr enabled on the 3560 & users only on the .186 network can get to the internet. The switch is running the ipservices license & the sdm template is "desktop routing" .
Users on the .184 cannot access the internet but we can ping the layer3 interface & the firewall gateway. [code]
Using Cisco 2960 series switches (Have 8 . 2 stacks of 4) to replace 6 old switches. 4 old switches had IP ranges of 192.168.6.*** and all new switches have 10.1.*.* addresses. Core switch has 10.1. as well as 192.168 ip addresses but i need to configure one vlan (5?) to route to 192.168 address. PC's on 10. address taking a long time to access 192 range.
I have a Cisco 1921 Router, a Cisco Catalyst 2960 and a Cisco Catalyst 2970 and I want the router to be able to assign ip-addresses by what VLAN a device is active on.
VLAN1: 10.0.0.0/24
VLAN2: 10.0.1.0/24
The router is connected to the Catalyst 2960 and there on to the Catalyst 2970 so the VLAN1 and VLAN2 is active on the to switches and the Router.is it possible?
I have a Cisco 2901 with the 4port gigabit ethernet switch module that I'm trying to get configured to have a seperate subnet for each port. So far I have it set up so each subnet is a vlan, then on each port I use the switchport access vlan command to tell it which subnet I want that port to be on. However, there is one port that I need to have 2 subnets on. The way I found to do that was to use switchport trunking on that port, but it doesn't seem to be working properly. how they would configure this? Right now I have vlan 101 as x.x.x.17/28 and vlan 103 as x.x.x.53/30. I think where I'm getting hung up is the proper association between the physical port and the vlan subnets.
We're going to be switching some of our gear from Foundry to Cisco, and were looking at the WS-C2960S-48TS-L. We currently have 3 different VLAN's, and I wanted to have 1 uplink back to our firewall (ASA 5550) and then let the firewall do the routing between the subnets. I realize that 1 link will carry the traffic twice then, but is that possibly with those switches to have all three vlans assigned to one port and then just let the firewall do the routing between the vlans or would I need to have 3 uplink ports back to the 5550?
We bought a pair of ASR 1004 to be installed at Primar & Secondary data center and one thing is to run OTV over it, but to do that, I have to extend multiple VLANs from my Core (Pair of Nexus 7010s) connected directly to the ASR is Primary Data center, I looked at some documents but didn't get a good idea about it, extend multiple VLANs from Nexus switch to an ASR.
I recently bought SG-300 28P to create the VLAN. My network hs 3 subnet 192.168.1.0, 192.168.2.0 and 192.168.3.0.My main net work is 192.168.1.0. I want to divide it to VLAN to eliminate the boardcast storm; especially from the domain 192.168.3.0
But I want all the devices from 192.168.1.0 to access other subnet.
I have a Cisco SG200 26 Port Switch, 2 Cisco WAP4410N Access points, and a VLAN aware Router. I have created 4 VLAN's. For the sake of this conversation lets call them.
The Access points are capable of doing V LAN tagging so I plan on having them tag a guest network as V LAN 101. That can get sent to the V LAN aware router and out. No problem. I have some devices, or management pages that I don't want accessible from the general network. (Intel V pro KVM, Remote Management Cards, AP Config Menus, Switch config menu...) . I need to be able to take a V LAN unaware device, plug it into port 1, and have it communicate with V LAN 98, 99 and 100.
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 recently set up a small photography business and am trying to get a Cisco 877 and Cisco SG300-10 switch to talk to each other.
What I want is for the Cisco 877 to handle the internet and the SG300-10 to handle the local network,
I have set up 2 vlans in trunk mode on the switch and want vlan2 to manage local traffic and vlan3 to handle the internet.
I have got the 877 connecting to the internet what I dont have, traffic going to vlan2 on the switch from the 877
Look at the running configs for the switch and the router and tell me how to get the vlan on the router to pass traffic to the switch. In a nutshell I am inserting the internet into the switch but am not sure how to progress. I have the c870-advipservicesk9 image file on the router.
I have an environment of 3 X 3560G of which I have 1st switch-CORE(f0/10) connecting to the VPN router(CE) interface-f0/0. Remaining 2 Cisco 3560's(Access) are connected to Gi0/1 and Gi0/2 on the 1st switch-CORE via gi0/1 . On all three switches I have created multiple VLANs and assigned ports to these VLAN. The switch to switch connection is trunk allowing all VLANs created on all these 3 switches. Now the issue is how I am going to have all these VLANs routed through single interface on the routeri-e f0/0, as all these subnets will communicating to remote site over VPN. What should be default gateway on the 2 Access switches and the CORE switch, also what static route should be on router to reach all subnets(VLANs) created on these 3 switches.
I have read inter-VLAN routing i-e creating sub interfaces on router but dont want to proceed with that and looking for any other way to have my VLANs talk on all three switches and then are accessible to remote site ove VPN?
I'm having some problems setting up vlans to talk to each other on a 3550-12T switch. Its quite a simple setup I have, but I need to split my network up.
Currently I have a network of 192.168.25.0 255.255.255.0 I want to create a new vlan network of 192.168.30.0 255.255.255.0 So I have configured my vlan1 (default vlan) to have an ip of 192.168.25.250 for getting to the management page
I have created a vlan2 of 192.168.30.1 255.255.255.0 ?I have a port 10 linked to one of my 3560G's?In port 9 which is on vlan2 I have my pc plugged in with a static ip of 192.168.30.50 from the router I can ping any device on 192.168.25.x.
I can not ping 192.168.30.1 (which is my vlan2) nor can i ping the PC.
I have enabled ip routing But I dont have a default route, this is becase we don't have a router on the network.
I am a fairly basic configs that I just can’t figure out what I am doing wrong. I have what I would consider a fairly basic config that I just can’t seem to get to work and I am sure it is something I am just not doing or grasping. Basically I have two 3560 switches that I would like to connect together with four 1Gb ports and trunk four vlans across said port-channel, I created the port-channel and set it to switchport trunk encapsulation dot1q I then set all four ports to channel-group # mode on. With that setup I can’t ping from switch to switch on the nonnative vlan.
I have a 3560 switch with 1 VLAN (VLAN 10) where I need to make ports:
1-10 as isolated (can't contact each other) 11-20 as community (need to contact each other like a normal VLAN) 23 as promiscuous (server that ports 1-20 need to get to) 24 as promiscuous (WAN router where ports 1-20 need to get to and the remote servers).
I'm using CISCO 3524 switch as access switch and trying to enable voice vlan in fast eth ports as below.
L3 vlans are created in core switches which is cisco 6509 vlan 1 - data vlan vlan 2 - voice vlan in cisco 3524
[code]....
if i use the above configs, the phone which is connected to interface fa0/1 is not taking ip from dhcp server. even it didn't work with static configs.while troubelshooting, i have configured as below and it's started working..
int fa0/1 switchport acces vlan 2 speed 100 duplex full.
in this case i can't use this port for data connectivity where as it's required for data too.
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.
In my setup , i have one core switch 4506, 3750 access switches and 4948 server switch.i have created the mngmt VLAN in every switch.the problem is i can ping the every device mngmt ip from any internal network,but my server switch mngmt ip i am not able to ping.trunk link is configure between the core and server,access switches.What is the problem with 4948 switch?
