Do you have the ability to setup DHCP servers on this layer 3 switch? I know I can with my old 3550 switch. Want to upgrade and make sure this model supports setting up dhcp servers on it.
After configuring DHCP, all the users needs to get IP from USER VLAN and all the servers should get IP from SERVER VLAN. If yes, what are the steps as I am very new in this kind of configuration.
is it possible to run a Catalyst 4500 as pure Layer 2 Switch, i.e. disabling "ip routing", but still managing the switch via Fa1, i.e. the defautl mgmtVrf vrf ?I tried the following:
! no ip routing ! interface FastEthernet1 ip vrf forwarding mgmtVrf ip address 192.168.1.1 255.255.255.0 ! ip route vrf mgmtVrf 0.0.0.0 0.0.0.0 192.168.1.254 ip default-gateway 192.168.1.254
I was not able to reach the Switch even from the same subnet. Only after enabling ip routing I could manage the Switch. I haven't found any command to set ip default-gateway for a vrf. Any workaround to keep routing disabled, but still manageable via VRF?
I have made a topology by using one 3560 switch and 2 2950 switches. I have also made 2 vlans name Clients and other Servers and vlan 1 is for anagement purposes. The left 2950 switch is for clients and the right is for servers. Clients is vlan 2 and servers is vlan3 . Now what i want is that my dhcp is should assign ips to clients in vlans 2 provided that servers are in vlan 3. I am also using a border router and i have introduced a default route on the 3560 to the border router.
Now when i assign static ips to my clients pc and server dhcp then i can ping between vlans but when i try to assign ip through dhcp then it wont work. Also the default route on the switch to the border router doesnt seem to work. I can ping only the border router when i put a default route on the border router instead of the 3560 switch.
I am trying to setup my 3550 layer 3 switch to do hand out dhcp addresses for different vlans. It is connected to my router address 192.168.1.1. I setup a new vlan 3 and the dhcp pool.. The client gets a 192.168.3.2 address but am not able to ping the router and other clients and get out to the internet.
Here is the config that I have. I deleted the other ports because I am not using them. The vlan 3 client is on port fast Ethernet 0/17 and the router is connected to the fastethernet 0/1.

Is it possible to to build a Layer 3 ether channel from two separate physical switches (layer3) that are trunked together?I know you can easily do this on a single switch and on stacked switches which I've done but in this case the customer have purchased two 3560X's which are not stackable yet want redundancy. The purpose of the etherchannel is to connect both switches to a private circuit provided by the hosted partner then route to the same setup in the DR location to different subnets.
My management has tasked me to give them a high level overview of the different switching we can choose for our new building.
This is what I know so far.4 Closets, each closet has 450 ports,One MDF room that is will contain one UCS Chassis and a Nimble iSCSI SAN.

I'm attempting to configure a Catalyst 3560-X Switch to act as a DHCP Server. There is documentation that supports this feature. Below is my config procedure however after the completed procedue no IPs are handed out to clients. [code]
I Have a problem I'm trying to configure automatically my switch over ther DHCP when I start the switch it request an IP from the DHCP from here everythings is fine but it does nothing more,indeed I put on my dhcp the option 66 and 67 which is an adress of my TFTP server and a file to download and the switch seems not to understand theses options , I tried my dhcp with a cisco airport and everythings works fine the File from the TFTP is automatically downloaded into the airport...There is an option to add or am I missing something in order to make it work with my switch ?
I live in a condo building that uses 3 Cisco Catalyst 3550 switches connected to a Comcast router with 100 Mbps download. Currently we regulate bandwidth by providing each user with 3 Mbps download. Even if only two people are active they still only get 3 Mbps download. I would like to set it up so if two people are using they each get 50 Mbps; a sort of 'dynamic qos. Is this possible with these switches? Would we have to purchase a Cisco router in order to provide this feature?
if a connect to the switch via Internet Explorer or every other browser I can't enter configuration because I receive a screen as you can view in image below. And I can view those errors:

We have two catalyst 3560X 24T-S switches connected on two separate LANs (both the networks are redundant to each other). The last port of the switches are connected together?
i want upgrade my catalyst 2960S and 3560x at midnight, but i am worried about config loss. If i upgrade my switch throught web interface, will need I reconfigure the switch?
I'm trying to upgrade some of the netwotk in my workplace.To do this I have istalled a 24port Catalyst 3560X switch.I'm looking to link it to my exsisting network via fibre.
I spoke to a local Cisco supplyer who recomended the above switch and an Allied Telesis Media converter.
I cannot seem to get the Allied Telesis unit to connect to the cisco switch.I have proved the fibre link by connecting 2 AT Media converters over the fibre.Do I have to enable something on the Catalyst switch or is the AT Media converter not compatible with the Catalyst switch?
Need to clarify if ip sla icmp echo operation is supported in catalyst 3kx switches (ip services)? on the configuration guide, commands are available, but on the feature navigator, i can't find the feature, only ip sla video operation. i don't have a device to test on here.
I have two 3560x Catalyst switches setup between two different locations. They link via a PTP line (Layer 2). I have setup Intervlan routing between the switches and that works fine.Each location has a separate subnet and a Windows DHCP server for each subnet.I want to block any DHCP requests to be sent from hosts on one subnet to the DHCP server on the other side (i.e across the PTP link) What is the best method to do this?
I've been conducting research on configuring 3 distribution switches in my network which are Cisco Catalyst 4507's to communicate with our core over layer 3. Our core switch which is already configured at Layer 3 for intervlan routing is a Cisco Catalyst 6509.
I've got the configuration portion complete and all devices are able to communicate my only question is about QoS. Do I have to configure QoS at the layer 3 interfaces for voice, if so how is that completed. We have several vlans and separate the vlans for each building by voice and data. We only configure ports on the access switches with voice vlans for QoS and we use the auto qos option on these interfaces.
We have a small site that has an Avaya voice switch connected to a c3560x switch.The avaya tech told us to set this on our ports to which the phone and the desktop are connected.
I was viewing the 3560x switch datasheet and i need network module C3KX-NM-10G. I have dark fiber with over 12 km distance to i guess i will be needing SFP EX for single mode.
I acquired a 3560X-24P-L Switch which I wanted to use at our datacenter. However, I need a switch that supports OSPF. It came with a Universal IOS but there was no "Router" command under conf t. I downloaded and applied the latest "IP Base" IOS, but still no Router OSPF. Based on the matrix here > [URL] I thought "IP Base" supported OSPF, but what exactly is "OSPF for routed access" ? Do I actually need an "IP Services" IOS? From my download options, I do not see an IP Services IOS for the 3560X-24P-L so I'm left to assume that the switch does not support L3 / OSPF. So my question is this particular switch supports L3 / OSPF and what is Universal IOS?
I am trying to join a Cisco Catalyst 3560X-24T-L to an existing VTP domain, my question is what configurations should I do to this switch?I have already gave it a hostname, setup passwords, enabled telnet, created a management address on port g0/24.I would like it to be on VLAN 13, is this done from my server switch, or done on the new switch?
I haven't worked with infrastructure much lately but planning on replacing a Dell switch used for a small iSCSI SAN with a Cisco 3560x. Switch is sstorage ONLY, network handled through different switches. I believe I want to disable spanning tree and configure trunking for the 4 GB ports connected to the storage array. The switch is providing connectivity to SAN via multiple GB connections and then also multiple GB connections to 3 Vmware hosts.Can you look over the changes I made to config below and let me know if I am on the right track.
I also plan to add a second switch later with the 10GB modules to interconnect for redundancy (but not worried about that part for now). I do not plan on using jumbo frames.
Here are my questions
1) Is the best way to globally disable spanning tree for the switch?
2) Did I trunk the ports correctly below?
3) Should I apply any specific SmartRoles to the 4 SAN NICs (GE1-4) or to host NICs (GE13-20)?
4) Anything additional I should do to handle iSCSI data?
Here is a copy of the config so far with my changes marked in RED.

i have a cisco 3560x poe. ny currnet version is 12.2(58)SE2.the cpu process is aboute 30% average.my problem is- ping to the switch itself show me 12ms which is high latency.*note- data between two hosts no this has no latency.i realize the packet go into the cpu itself but, the cpu is not loadedusy. so my question is- is this natural behavior?
I got one SF 300-48 layer 3 switch I tried to configure to use it in the office network.Unfortunately I'm unable to configure the VLAN settings.I need port one for input(VLAN2),port 7-15 for another vlan(vlan3) also need to connect with the vlan 4.port 15 is another vlan(vlan4) this is for wireless.Other ports are static.It doesn't get any connections with other vlans.I wish to know how to configure vlans in GUI mode.I tried , But I can't get the Vlan setting correctly.Also,I need to know how to communicate both vlans in GUI mode.
I created a lab and I have a few issues. One with a layer 3 switch and another with a ASA 5550.
1. Layer 3 switch: I have created multiple Vlans and I am able to route between them. I can ping the switch IP but not the default gateway to the ASA. I did a tracert of the default gateway of the ASA and once I am past the Vlan gateway it fails.
2. On the ASA 5550 I created the Vlans on sub-interfaces but still cannot get to the internet. ASA config is below the switch config.
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

I can understand it 's one of those very basic questions , but how do I identify a Switch is Layer 2 or Layer 3 ?Looking through # show version command and checking the IOS version to be IP BASE or LAN BASE . Is it the right way ?Cisco 2960 is a Layer 2 or a Layer 3 Switch ? I noticed that access-lists could be configured which means that it 's a Layer 3 Switch , right?
I've created a scenario using a 3750 cisco as core switch ad other 6 switch model 2900 in access level.my problem is this, the router is not a cisco router, and this router is not able to make NAT on more than one subnet.Into the core switch I've created 4 VLAN and I must to give internet access to 3 of them, 192.168.0.0/24 (vlan1), 172.16.0.0/24 (vlan2), 172.17.0.0/24 (vlan3).I've connected the switch to router via gigabit ethernet 0/1 and I've assigned to this interface ip address 192.168.10.2, the router ip address is 192.168.10.1, Switch ip default-gateway is router ip address 192.168.10.1, ip default route is 0.0.0.0 0.0.0.0 192.168.10.1 I've enabled ip routing feature and I've set no switchport feature to interface gigabit ethernet 0/1.From core switch I can ping router ip address but I can't make it from all other user, and the users not able to have internet access.

My understanding is that even layer 2 switches like the Cisco 3500XL can have 1 IP address for management. However, I cannot seem to figure out how to configure it to get it working in a router on a stick setup. I can manage the router through SSH, but I cannot SSH to the switch.
