I have to use 9 Cisco 300 series switches to build a new network. I will use one of them (core switch) in L3 for routing between Vlans (3 Vlans) and the others in L2. Is there a software to centralized all switches configuration, operation and monitoring?

I need to know whether the configuration which I mentioned in scenario is enough for apply DHCP snooping in my network.
we are using cisco 6509 series switches as core switches. and Cisco 4510,4507 series switches as edge switches. all the vlans are created at core switches and propogating to edge switches through VTP. we are using OSPF as routing protocol at core switch for internal routing. till now we are using 4510,4507 switches as layer 2 switches. Since, 4510 & 4507 switches are hign end swithces i want use them as layer 3 switches instead of layer 2.if i change these switches from layer 2 to layer 3 does it make any impact on our network or better to keep them as layer 2 switches.if i change these switches to layer 3 is there any advantage i will have.

1- fitst slot on fist switch connected the second slot last switch in the stack.
2- second slot/ port on the first switch to the first on second and seoncd on teh second switch to first on the third switch.
this how they are alway been stacked.Now, I need to connect power cables and I have followed the same method for stacks up to 4 switches. it seems that if a stack has more tham 4 switches, then the cabling will be dofferent!?I was wondering what will be on the cabling scheme for stacks more than 4 switches.
OSPF normally only comes with IPservices image and not IP Base image. The 3560-C series data sheet says that it only suport IP Base image, yet it mentions that support for OSPF in included. Are there any restictions in the OSPF support?.

I am little confused about the location of FIB table and adjacency table in both cisco 6500 series and fixed ports switches .In case of 6500 series switches
"Central CEF mode:The CEF FIB and adjacency tables reside on the route processor,and the route processor performs the express forwarding. Use this CEF mode when line cards are not available for CEF switching, or when features are not compatible with distributed CEF."
If line cards do no support CEF, then FIB and adjacency tables are built and are located on route processor( control plane ). Data plane operations are implemented in software and route processor performs those operations.
Some Cisco switches actually use different hardware to control the different planes. For example, the Cisco Catalyst 6500 is a modular switch that uses the Multilayer Switch.Feature Card (MSFC) for control-plane operations, and the supervisor Policy Feature Card (PFC) for the data-plane operations.
Supervisor module has has MSFC and PFC. MSFC implements control plane operation where as PFC implements data plane operation.But the first paragraph says in Central cef mode, both data plane and control plane operations are implemented by route processor. [code]
Do these switches implement the Central mode cef in same way as mentioned above. i.e
"Central CEF mode:The CEF FIB and adjacency tables reside on the route processor and the route processor performs the express forwarding. Use this CEF mode whenline cards are not available for CEF switching, or when features are not compatible with distributed CEF."Or fixed ports switches such as 3750 implement data plane operation in hardware where FIB tabe and adjacency table are maintained on Data plane.
Any configuration example to build a vpc b/w 5ks and 7ks? i have total 4 links between them . If not, I am assuming to have the following config for the port-channels:- (Provided the vpc domain is configured).
N5k1 and 2:
int eth1/10-11
channel-group 10 mode active
switchport mode trunk
int po10
switchport mode trunk
switchport trunk allowed vlan a-d
[code]....
So, its basically vpc 10 that has 4 physical links b/w the vpc domain of 7ks and vpc domain of 5ks.
The 6509 Series Switches support the scenario VSS Active-Active Chassis, I would like to setup both switch's as one virtual switch but working at the same time, not with Active - Stand By Chassis.
My plans it to create PortChannel accross both Switches 6509 in order to have 2 links one connected to one slot/switch and the other connected to slot/switch in the second 6509 for servers redundancy.
I plan to build improved redundancy in to my LAN by stacking two 3750s and teaming pairs of NICs on my Dell PowerEdge servers, with each cable of the pair going to a different switch.In my mind this provides redundancy for the NICs and the switches. Does this configuration will work, and also what type of teaming is supported, as I was planning to have one NIC active and one standby, but can I run this configuration with both NICs in the team as active with load balancing?

I'm looking at the possibility of purchasing a few 3750 to build a switch stack to replace my current core and access switches. I'd like for the stack to support server, SAN, and user traffic, as well as provide simple switch management, redundancy, and failover. I've also been looking at the 4500, 6500, and Nexus series switches (although the Nexus switches maybe a bit too much for my network).
My current environment consists of 3560's as the core/distribution/access switches, a mixture of Hyper-V and VMWare environments (although we're slowly migrating to Hyper-V), an HP SAN (P4500), and about 100 users. Any issues going with the 3750's or have an alternative, more efficient solution?
I have some questions in regards to network equipment I want re-utilize for my distribution layer in one of my buildings.The choices at the moment are:
OPTION 1.) 2x WS-3550-12G's (HSRP)
OPTION 2.) 1x WS-6509 with cards:
What option would be better from a performance aspect? We want to have network, voice, and wireless data go through this distribution layer switch(es).This is exisiting equipment I already have and can not buy anything else at the moment.
I have a site that is very dense, but not high throughput. I have 4x48 port switches all 3560 and 1 2851 router. The switches are pretty much full to the brim but the site is never completly lit, they just like to move around a lot. However i wanted to provide this site with as much redundnace as possible. So my first thought was to build redundant pathing with the switches so that they could loose a switch and not have a single point of failure. So therefore I built a ring. SW1 to SW2, SW2 to SW3, SW3 to SW4, SW4 to SW1. To make this even more redundant against port hardware failure, i used two uplinks for each and built an etherchannel. is it good practice to use Etherchannel and Spanning Tree together?So i now have a good redundant LAN switching topology. I have multiple VLANs at the site so I am using Rapid-PVST. I did not set priorities on the switches as I don't think that is really truly necessary, but correct me if I am wrong!Ok so next step is to make sure that my WAN connection for all of these switches is redundant. I have a 2851 router, with 1 of the built in interfaces dedicated to our ethernet hand-off WAN connection (MPLS in this case using BGP routing). The other would be used as an uplink. I also got an additional card for the Router so that i can have redudant local LAN connections. I then built up some IRB bridges so that I could uplink the Router to SW1 and SW3. Is it good practice to use IRB Bridging on a Router to provide redundancy?So at this site i have the first part running, and it works pretty well but I have had 1 strage issue, which has to do with after a failure and re-convergence of spanning-tree, it seems that DHCP starts failing to work. I actually had to go into each of my switches make a dummy VLAN interface and put on helper-addresses to get them to work. They are not L3 switches (programatically speaking) so they should just forward the broadcast packet onto the router, which DOES have the helper-addresses programmed,Also at another site I have the bridge router setup configured, just without so many switches, and no etherchannel between the switches. This seems to work flawlessly, but the site is very small so performance issues would be difficult to spot since they are just thin-clients coming back to a Citrix server over a single T1.
View 1 Replies View RelatedSo the SG300's have STP on them and prevent network loops when other switches on the network also support STP too. However, if someone plugs in a non-managed switch that doesn't support STP with a network loop, is there anything within the SG300 switches to isolate and/or prevent that from happening?
(I currently have port mirroring turned on for one port and a network sniffer attached awaiting the incident to happen again).
I've seen lots of posts from people having problems routing traffic between two vlans with some complicated examples. Any simple step-by-step example for an SG300 switch (in layer 3 mode) to configure two vlans and sending traffic between the two vlans without an external router?
-VLAN1 10.10.10.0
-VLAN2 10.10.20.0
I've tried to do this through the GUI and can't seem to make it work. I'm missing something in the GUI.
I have a SG300-28P switch. I just read in the Administration Guide that, when in Layer 3 mode, the switch doesn't support MAC-based VLAN or Dynamic VLAN Assignment.
So, in order to assign a client to a VLAN based on their MAC or based on the response of a RADIUS server, we have to disable layer 3 features. Without layer 3 switching, the switch is unable to act as a default gateway and forward packets between VLANs. As a result, the VLANs can't communicate in any way, or access the internet, unless a separate router is connected to every VLAN. Right? Doesn't this limitation significantly reduce the usefulness of the DVA feature?
we have three separated network segments going to one Cisco 3750 switch all is L2 .. from this switch is 100 mbit uplink.we need to apply some Qos mechanism not to saturate line by traffic from one network.. Configuration from various reason CANNOT be done on switch where 100Mbit line is terminated.. so all must be done on SW1,2,3..Correct me if iam wrond but as switches doesnt see traffic from other network iam affraid only think we can do is limit bandwidth on links going into SW1,2,3 to 33 Mbit.I found commad srr-queue bandwidth limit.But links going to SWs are 1Gbit so if i force bandwidth to 10% (minimum what command allows) its 100 Mbit..If I force speed on those links to 100Mbit and than apply srr-queue bandwidth limit to 30% doest it work.??. Will srr-queue bandwidth limit speed to 30Mbit?? Or srr-queue bandwidth limit is calculated from maxim speed of interface?

The objective is to route specific VLAN traffic and the caveat is that I have multiple VLANs with the same network address.

View 7 Replies View Relatedsetting up a single home network in my apartment that will be able to connect to and use 2 separate wifi internet connections to provide stability and reliable bandwidth for a home network.
Situation: I have recently moved into an apartment complex that has 2 separate wifi connections that are available to the residents free of charge. (yes i am authorized to use both) I do have the option of paying for and having my own personal DSL line installed but I would much rather use the free wifi and not have the monthly bill.
The Problem: My apartment is located far enough away from each of the routers (One wifi at each end of the building and I am in the middle) that my signal strength is poor most of the time and sometimes heavy traffic on one wifi requires that I disconnect and connect to the other. Wifi A is farther and has very low signal and low or no connectivity. Wifi B has good signal most of the time but gets very slow during peek usage times of the day.
I understand that I need one or more high gain antennas in order to receive adequate signals from either Wifi connection.
Between me and my son we have 2 laptop PCs, 1 Desktop PC, 1 network printer, 1 Xbox, 1 HDTV and my smartphone. I don't want to try to equip each device with its own high gain antenna and try to figure out which device should be connected to which Wifi depending on available signal and bandwidth. Rite now I do not have a Home network set up at all and we are only using 1 laptop and the Xbox and each is directly connected via wifi (usually to Wifi B).
If I could connect to either Wifi A or B with decent bandwidth and reliability and then be able to network or connect all my devices via wireless or wired to my own router/extender etc. I would be happy. However.. Given that I must share bandwidth with the other residents and at times one Wifi has heavy use while the other does not. I have been trying to research how to connect to both wifi signals for load balancing, reliability and hopefully greater bandwidth.
