i'm using some catalysts 3560 with 10 VLANs and inter vlan routing. we use a windows deployment services server to install our workstations. the pxe boot works fine. the image is loading, and when the windows 7 PE is booting, the dhcp request failes. when i use a small not manageable switch between the computers and the catalysts, it works fine.all other things work fine.
View 9 RepliesWe have recently implemented Windows Deployment Services on our local network, but everytime we do a multicast image deployment the network get flooded to point of total saturation.
We have Netgear switches and a Cisco 2800 series router. IGMP Snooping has been enabled on all Switches, however, we are unsure on how to implement multicasting on the router.
The whole network is flat - no VLANs over than the default VLAN1. We only want multicasting to work within our local network and does not need to go out the other side of the router as that is the connection to the internet.
How to get the Cisco router configured properly to enable multicasting to not flood the network. It seems that even if we were to image 4 PCs using multicast this is enough to completely get the network flooded.
Also, am I right in thinking that IGMP needs to be enabled on all of the Switches?
WDS allows you to capture and deploy images on a network to client pcs. I Was wondering how many images wds allows you to capture and deploy and if there were any work a-rounds that would allow you to deploy more.

View 2 Replies View RelatedWe have a server connected to a 3560 switch which in turn connects to 6500s. The gateway interface is on the 6500. We will be changing the 6500s so the mac address for the gateway will change, however the IP address will remain the same. As we change out the 6500s the uplink connections to the 3560 will go down. This will flush the old mac address from the 3560.When the 3560 removes a MAC address does it update servers so they have to relearn the correct MAC address?

View 1 Replies View Relatedwe have a 3560 switch configured with EIGRP with dhcp. We have a user that we cannot ping, however the interface show up / up and no errors on interface. the ip address is 10.2.0.199 - however we have dhcp configured to exclude the range from dhcp ip dhcp excluded-address 10.22.0.1 10.22.0.200 how can this work station get a dhcp address if we have that ip range excluded from the dhcp pool?
The user is off a different switch that is a uplink to this distribution switch. Traceroutes shows that the problem is with the distribution switch.
I have Cisco 3560x layer 3, but there is one problem with MAC ACL. Here is sample scenario:
I have two V LANS 2 & 3. There is one device (D1) on V LAN 2 and three (D2,D3,D4) devices on V LAN 3. D1 can talk only to D2 and D3. D4 can talk only to D2 and D3. D1 and D4 cannot talk at all. I got the IP access list all set, but I was asked to get the MAC ACL on it. The problem is that as soon as packet is routed, its MAC addresses will change, correct? Is there way of preventing device with same IP but different MAC from talking to device it should not to, keeping in mind that the packet will be routed?
I've set up my 3560 to do routing. Now, I'm looking for a way to apply acl restrictions to the vlan interface ip address itself.
View 1 Replies View RelatedI have some Ethernet-connected cameras that all have the same Ethernet MAC address FF:FF:FF:0A:0A:0A. They were originally designed to directly connect to a Windows PC, but they can also connect through a simple unmanaged switch.A Catalyst 3560 switch won't forward packets to or from anything with that MAC address, at least not by default. Is there a way to convince the switch to do so?
It was my hope to replace the dedicated connections we have for these cameras with a separate VLAN for each camera, and switch them through our existing switch network. Given that all of the cameras use the same MAC address, putting them on the same network is out of the question, but different VLANs, where the only two devices on each VLAN were the camera and the PC that uses it, would be fine.
The switches run IOS 12.2(55) SE through SE3. I learned the camera MAC address from the PC's ARP table while the camera software runs; it turns out the cameras don't have a full IP stack either and don't even do ICMP.
I have 2 3560 switches that are running 12.2(25)SEE2. Port security is enabled on some of the ports. Whenever there is a power failure, when power is restored, 1 port on each switch goes to err-disabled. The mac address that causes this is a valid address for that port. Below is the configuration on one of the ports.
View 1 Replies View RelatedMy actual Scenario
1 x 4500 and 1 x 3560?They are gateways of 8 Vlans?They are doing HSRP in each of those Vlans?The 4500 is the Active?There is a DHCP Pool for each of those Vlans on both gateways using "ip dhcp excluded-address" I ensured that the range of provided ips by each DHCP server will not be overlapped Obs.: Reducing the lease time, I ended with the calls bringing related problems.
OK, every thing is blue, every thing is fine.But the network diagram is realy complex(41 switchs, 89 uplinks), and depending of how is the network flow, one or other server answer first or latter.
For many reasons I would like that the secondary DHCP server would answer only if the primary DHCP server goes down.To me, the bigger reason is that DHCP database would be only in one DHCP server.But there is other reasons.
I passed by many frustrated solutions:Try to force a delay on the answer on one of the servers. - Impossible.Try to disable DHCP server, and, using EEM, enable it only if router became active in HSRP. - I couldn't do It.
What I'm thinking now is use the HSRP resource to resolve it.On both routers I would put a "ip helper-address" pointing to an Virtual_HSRP_IP.And depending on which router is the active, him will answer the request.
My first doubt is:Would it work?The second doubt is:Could I use the same Virtual_HSRP_IP that exists on that Vlan(see example 1),or I would need to point it to a Virtual_HSRP_IP in a different Vlan(see example 2)?
Example 1
-----------------------------------
| 4500 |
-----------------------------------
interface Vlan1
ip address 10.10.0.2 255.255.0.0
ip helper-address 10.10.0.1
standby 1 ip 10.10.0.1

We have ip arp inspection and dhcp snooping enable in couple of 3750 and 3560 switches. Everything works fine, excepted few case that DAI packet rate trigger and errdisable the port. Later on we found out that most of computer that trigger DAI is Windows 7 and especially when they are in sleep mode. Not sure if anyone experiencing it with Windows 7. Also we have it rate limit at 64.
View 2 Replies View RelatedWe have our Nexus as our default gateway (101.1) and the default VLAN1 is setup with two subnets 101.X and 102.X. The DHCP server is using a superscope setup to accomodate the overflow of devices requesting IPs on 101, so when 101 is consumed persons are able to obtain a 102.X IP address. The setup is basic on superscope. The issue is some times the routing to the firewall with a 102.X is not always 100%. Somedays all goes well and the 102 subnet is routed out to the firewall and its a good day. However, such as today a 102.X address is not routing as it did 24 hours ago. I am perplexed as to why this is behaving unpredicatable. Here is running-config for VLAN1 to show the 102 as secondary address to VLAN1.

View 2 Replies View RelatedWe currently have an existing 6506 in data center that we want to add another 6506 to and do a VSS implementation.I'm trying to minimize down time so our current basic plan was to do the following:
1. Bring up the new 6506 and configure it for VSS
2. Trunk a port between the new 6506 and the production 6506
3. Physicall move connections from the production 6506 to the newly connected VSS switch
4. After all physical ports have been moved, power off the original 6506 swap the supvisor card out for the new 2T Sup card
5. Configure original 6506 for the virtual domain and then connect the VSL's.
According to the documentation, to run "switch convert mode virtual" the standby unit has to be in hot standby. This means I can't run this prior to moving the connections over, which means once I run "switch convert mode virtual" it will reboot the switches (~ 9 minutes of down time). Is there anyway around this?
What is the preferred access switch for new deployment. Choosing between 3850 and 3750x. I have to say that the 3850 wireless features will not be used in this deployment and 4 switch for stack is enough... Looked and read everything that I found in the press, I can not make an informed choice. I bow to 3850, but I was apprehensive following circumstances:1) not too positive reviews2) to long list of open caveats3) to long list of features are not supported in Cisco IOS XE Release 3.2.0SE4) IOS XE : (With regard to the first three points - yes, I understand that the product is new and it has not gone further stage of "childhood diseases" ...Regarding the fourth point - I understand correctly that this is the direction to be moving Cisco Systems and soon all products migrate from classical IOS to IOS XE and so on?

I am still working on the design of my big project and always that you think that every thing is solve, appears a details.We need to deploy a fiber links to some buildings that will have access switches connected to the Core. I have been reading about ethernet ring topologies and quite differents to the hierarchical model because of the using of Ressilent Ethernet Protocol instead of STP or RSTP.My question is which of the next to scheme will be the best?
1.- Deployment an ethernet fiber ring topology with REP? Consider that the edge Switch of this ring will be my Core and this one is connected to my distribution switches in a hierarchical topology. In this situation, Acces Switch 1-A is connected to Acces switch 1-B, Access Switch 1-B to 1-C and Switch 1-C to the Core. Feel fre to recomend me wich switches and considerations are the best. We conssider 1 Catalyst 6506 Chasis for the Core and catalyst c2960s-48-TDL for acces, maybe the 3750x series. Each Acces node in the ring topology will have a maximun of 50 end devices.
2.- Deployment a Fiber ring but not connecting each switch with the next. In this case we want to ensure redundancy to the core wih equal costs path, but because of the ring each switch won´t have equal length link to the core. In this situation, Acces Switch 1-A is not connected to Acces Switch 1-B is connected directly to the core but the fiber cable will take the route to Access Switch 1-B, to Acces Switch 1-C and finnally to The Core Switch. This apply to the other to Switches. Note now that Acces Switch 1-A will have a 281 Ft link to the core and a second 1612Ft. link to the core. Here comes the question this differents lenght will negative affect RPVSTP ? or It doesn´t matter? Can i setup an etherchannel/load balance in this situation?
