Configuring C3560X as a Layer 3
Hi,
Currently my network has a Cisco 3825 performing all the vlan routing work. I have a Cisco 3560X behind it that could be configured as a full layer 3 switch, thus removing the need for the Cisco 3825 altogether or at least optimizing the functions of the 3560X.
The C3825 has a mix of subinterfaces off one of the gb interfaces and FastEthernet interfaces configured with a total of 9 vlans. My initial plan is to configure the 3560X to deal with the vlans that are configured in the subinterfaces. Therefore, I'd basically need to move those subnets and vlan configurations to the 3560X. The vlans that are tied to the FastEthernet interfaces would remain in the C3825 (until eventually moved). Will the switch support this configuration? In other words, even if it's configured to act as a full Layer 3 switch, will it be able to send the traffic to the C3825 for those vlans that it doesn't have layer 3 configurations for?
Part of the info that I didn't include in my initial post (mainly to keep things simple) is that there's a Barracuda webfilter 410 between the 3825 and 3560X. Whoever implemented this, thought it was a good idea to have a device with an interface that maxes at 50Mbps right in the middle of the core of the network. Because of this, I can't move all the VLANs to the 3560X at once. I want to move some of the vlans that have lighter traffic and let the 3825 handle a couple of the vlans that deal with external web traffic and that can potential have higher traffic rates. I'm including a partial diagram of the layout I'm considering.
Questions:
1. If I move three vlans to the 3560X, how do I have to modify the interface or routing table configuration in the 3825 so it forwards the traffic for those vlans to the 3560X
2. These are the configs (in general) that I plan to implement in the 3560X
2.1 Enable routing on 3560
ip routing
2.2 Configure vlans IPs in 3560
interface vlan6
ip address [vlan ip] [vlan mask]
no shut
Repeat for every vlan
2.3 Configure interface to 3825
int g0/48
no switchport
ip address [switch ip] [switch mask]
no shut
2.4 Configure default route for 3560
ip route 0.0.0.0 0.0.0.0 [router ip]
I'm assuming that the static route that outline above will be enough to allow the 3560X to forward the traffic for the VLANs that it is not managing. Do I have to configure this static route to be tied to the interface that is connected to the router? I believe this is a global command, but this scenario may consider it otherwise.
As you can see in the diagram, there's a Cisco 2960X that is connected to the 3560X and that the web servers are connected to. This is to facilitate traffic between the VLANs and the WEB VLAN. With the 3560X doing the intervlan routing, the traffic to the WEB VLAN will go to the 3825. This may or may not be a desired result. So is there a way to direct traffic from VLANs 10, 20, and 30 to go through the trunk to the 2960X?
At some point the Barracuda web filter will be out of the picture. At that point all the VLANs will be routed in the 3560X

WS-C3560X-24 needs to be connected with another WS-C3560X-24 core layer 3 sitch.
I got new task moving WS-3560X24 port layer 3 core switch from one branch to be moved to my branch and connect WS3560 layer 3 core switch my site network. Both core switch has got 3-4 cisco 2960 switch underneath and lots of vlan offcourse. I am thinking about creating etherchannel between these two switch.
Any suggession and advise will be hightly appreciated.
Thanks in advance.So today you have one core 3560X switch with layer 3 interfaces for all the VLANs which go out to your Access layer 2960 switches - correct?
We would typically see a core (Cisco would call it "distribution" layer in such a case becasue they don't consider the 3560 full-featured or powerful enough to call it a "core" switch) made of of dual switches connected with a trunk port (may be multiple physical ports in a port channel for higher availability and throughput). Each access switch has trunk port connections to core switch #1 and #2. At layer 3, core switch #1 and #2 setup hsrp groups for all VLAN interfaces.
That's the high level approach that most closely resembles a reference architecture. Have a look at the "LAN Baseline Architecture Overview-Branch Office Network" document for more information. -
Program Default Layer Writing Question
People...
An internet friend of mine in another forum helped me solve a
parent (container) layer centering problem. I had created a large
"Layer 1"...nested Layers 2, 3 & 4 within Layer 1...&
wanted Layer 1 to slide to the center of any browser window, with
2,3 & 4 not changing absolute position relative to Layer 1. The
solution was:
<div id="Layer1" style="position:relative; width:285px;
height:311px; margin: 0 auto;">
<div id="Layer2" style="position:absolute; width:47px;
height:115px; z-index:1; left: 226px; top: 120px;"><img
src="layer2.jpg" width="58" height="133"></div>
<div id="Layer3" style="position:absolute; width:131px;
height:115px; z-index:2; left: 3px; top: 3px;"><img
src="layer3.jpg" width="158" height="189"></div>
<div id="Layer4" style="position:absolute; width:176px;
height:71px; z-index:3; left: 94px; top: 130px;">;"><img
src="layer4.jpg" width="158" height="189"></div>
</div>
where the container (Layer 1) was assigned relative
positioning & centered by auto margins...& the nested
layers (2,3 & 4) remained absolute; & inline
...but...
...he also tells me that inline styles are not a good idea.
Everybody tells me that inline styles are not a good idea.
But no one tells me why.
So...3 questions:
1) Why are inline styles not a good idea...& is that
relative (pardon the pun) to the way I am now centering my layer
layout?
2) Is there a way to configure Dreamweaver to write layer
code (i.e., user draws in the layer...Dreamweaver writes the code)
other than inline?
3) On all of my existing page layouts that consist of
multiple layers (each one housing an image or text)...that I now
want centered...how do I nest those layers in a large container
layer? (the above centering solution was from a test page I created
from scratch...& the subsequent layers were nested as I went. I
now need to go back to existing pages & center the layout.)
Thanks very much,

Because the main advantage of using css is precisley to
remove the styles from the html markup, and
place it instead in an external style sheet. This allows you
to:
1.centralise the code that defines your layout in one place,
and thus have only one file to deal
with to update/change all your pages layouts.
2.Think of layout in a more precticall way by dividing layout
styles into coherent styles
definitions that you can then combine in various ways to
style various heml elements.
3.Keep your html markup clean and simple

maybe in DM8, but I don't think so, definitely not in MX6.
Side note: using Layers for layout is not a good practice
anyways, for many reasons, see below
>

> one housing an image or text)
what will happen if the user increases the text size in their
browser preferences? Try it: the text
will overflow the layers, and your page will look horrible,
with text overlapping images or other
text. Because you are using Layers. This would not happen if
you were using relative divs or tables
with no fixed height.

In short, consider NOT using Layers at all.
Use tables (easier) or realtively positioned divs (harder but
often more practical in the long run).

Using Basic or Multi-tier configuration for WLS Clusters...
Ok,
The scenario is: I'm using WLS6.1 (hopefully, version doesn't matter here)
with three instances clustered. Each instance provides all Services:
Servlets / JSPs/ EJBs / Database communication... I'm using the Basic
configuration described on the BEA documentation....
Now, I want to move forward to a Multi-tier configuration, where the first
layer will serve Servlets and JSPs and the second layer will serve EJBs.
The problem: On the first scenario, I was looking EJBs with the Default
InitialContext() constructor without the environment, since everybody was on
the same JVM...
What do I have to do, so my Servlets start looking for EJBs on the second
cluster now? Do I have to re-write every single lookup? Can I use a
jndi.properties file on the first layer - on the presentation tier?
Thanks in Advance,
Marcelo.
Thanks Patrick!
But my actual problem starts here. The Servlets aren't mine. We have to support
applications which run atop our product(which is a bunch of beans+RMI Objects
running on the top of WLS) in a backward compatible way with a standalone.
Will try and make a post if I can find a 'configurable' way out.

Hi,
Anyone implemented nac for wireless layer 3 oob? This is using nac appliance not ise.
What I did is to configure wlc as per layer 2 oob setup. Configure svi 669 (authentication/quarantine vlan) on switches that’s with the wism. Pbr all vlan 669 traffic to test cas untrusted interface.
Problem now I’m not able to get an ip from dhcp after associating. DHCP works when tested on wired. Is there any additional config to be done on WLC or am i doing it right??
The test cas/cam are ugraded to ver 4.8.2.
Regards
JoachimEveryone can do a mistake and it seems I did a big one :-)
l3 wireless OOB was not supported until last version :
§Wireless L3 OOB RIP has been introduced in 4.8.2.
§In order to support wireless in L3 OOB RIP deployment – DHCP release and renew values were propagated from CAS to the client so that client can perform IP refresh.
§The configuration of WLC and AP’s needs to be done like in Wireless L2 OOB VGW deployments.
§There are no ports in WLC hence Port profile is not required
§WLC allows only two VLAN’s namely Quarantine (Auth) and Access VLAN’s. Hence the support for User role Vlans is not there in Wireless deployments.
§iPhone/iPad support is also not present. Reason being IP address cannot be refreshed in iPhone/iPad due to lack of support for Java Applet/ActiveX.
§The authentication trap control needs to be checked in order for the WLC to send 599.0.4 trap. -
Hi,
i'm trying to configure SF302-08P in layer 3 mode.
ports 1 to 8 have ip phones and desktops, port GE1 in connected to a router (not cisco) that links to the internet.
i created vlan 100 and assigned to ports 1 to 8 (untagged)
i created vlan 200 and assigned to port ge1 (untagged)
activated dhcp server , created pool with 192.168.26.0/24 gw 192.168.26.1
|router A| (192.168.16.0/24 gw 192.168.16.1)
|
|
| GE1 (192.168.16.14)
| SF302-08P |
|
|
SPA504G+DESKTOP | SPA504G+DESKTOP
192.168.26.2 192.168.26.4
192.168.26.3 192.168.26.5
the problem that i'm facing is that SPA504G and desktops access the internet with their inter address 192.168.26.0/24 and not 192.168.16.14.
is there a way to achieve what i'm looking ? how does routing work in this case ? shouldn't there be some kind of NAT ?
thank youHello Luis,
Is there a particular reason that the switch needs to be in Layer 3 Mode?
I think your scenario would work better if you configure NAT on your router and let the router act as the DHCP server. Then, the switch could be in Layer 2 Mode.

I configure HSRP on two layer 3 switches (Switch A-Switch B), Sw A is connected to Router A, Sw B is connected to Router B
But I want to use also the Layer two features of my switch
- is it possible to use these switches also for LAN ?
lets say there is a simple LAN with 1 VLAN and 10 PCs. PCs have two ethernet ports, they are directly connected to L3 switches redundantly.
thanks for helpingthanks Martin
I want all of my PCs (total ten) in the same subnet
so what should I do is:
1. configure 10 ports of the L3 switch as switchport under VLAN 1 (these ports will conect ten PCs on the same subnet)
One port of Switch A will be connected to router A (2610),
One port of Switch B will be connected to router B (2610). So;
2. Configure one port of the each L3 switches as 'no switch port' and assign IP addresses. Since they are not switchports, I shouldnt create VLAN for them.
3. Configure HSRP
4. Configure EIGRP or OSPF
AFTER ALL: there is one VLAN that connects all PCs,there is one Layer 3 port on each Switches. And systems work :-)
Could you please confirm If I properly understand your post?
thank you very much for helping -
Hello everyone,
When configuring MST for STP, is there a need to configure it on access layer switches in a collapsed core design? I can find docs to configure the root and secondary root bridges but I don't see anything about configuring access layer switches. In RSTP, you configure it on all switches cooperating in STP and set the root and secondary bridges accordingly. Any help is appreciated.
Regards,
TerenceHi,
You should configure your access switches for MST as well so you are using the same STP for core and access. The only difference between the core and access is that the core is root and back up root for STP and the access layer is just default (32768).

Routing issue in Nexus 7009 due to vPC or hsrp
we have two site's, on first site we have two nexus 7009 switches (Nexus A & Nexus B) and other site is remote site having two 6500 switches. (design attached)
we are using hsrp on nexus switches and Active is Nexus A for all vlan’s
From one of my remote site user's (user's are in vlan 30 ) are not able to communicate with nexus site vlan 20 specially if host in vlan 20 take forwarding path from nexus switch B,
I can ping the vlan 20 both physical address's and gateway (vlan 20 configured in both nexus switch and using HSRP) from vlan 30 which configured on remote site 6500 switch
ospf with area 0 is the routing protocol running between both site.
vlan 10 we are using as a management vlan on both nexus switch that building neighbore ship with WAN router, it's means wan router have two neighbors nexus A and nexus B, but nexus B building the neigbhorship via a Nexus A because from WAN router we have single link which is terminated on Nexus A,
there is one layer 2 switch between nexus A and WAN router, nexus A site that switch port in vPC because we are planning to pull second link later to nexus B.
All user's are connected with edge switch and edge switch have a redundant uplink to nexus A and B with vPC configured
After troubleshooting we observe that if user in vlan 20 wants to communicate with vlan 30 (remote site), traffic is taking Nexus B is forwarding path, then gets drops.
I run the tracert from pc its showing route till SVI on Nexus B after that seems packets not finding route. Even vlan 30 routes are available in the routing table of Nexus B. we don’t have any access-list and Firewall between this path.Hi,
I suspect in your scenario that traffic is being dropped due to the characteristics of vPC, the routing table on Nexus-B may reflect the next-hop address for the destination IP, however if that next-hop address is the address of the Nexus-A off of VLAN 20 then it will be forwarded across the vPC peer-link, this breaks the convention.
When you attach a Layer 3 device to a vPC domain, the peering of routing protocols using a VLAN also carried on the vPC peer-link is not supported. If routing protocol adjacencies are needed between vPC peer devices and a generic Layer 3 device, you must use physical routed interfaces for the interconnection.
You can configure VLAN Interfaces for Layer 3 connectivity on the vPC peer devices to link to Layer 3 of the network for such applications as HSRP and PIM. However, Cisco recommend that you configure a separate Layer 3 link for routing from the vPC peer devices, rather than using a VLAN network interface for this purpose.
Take a look at the following URL, this article helps to explain the characteristics of vPC and routing over the peer-link:

How are different user names being created on my Apple ID accounts??
I can no longer access the Guest Account on my IMac running Snow Leopard. Guest account says I have the wrong pwd? Funny thing is I never gave it a pw! Once before I found the Guest Account configured in a lower layer IFrame with several missing programs from my personal account being used by it. No one else has physical access to my Imac, although I often see activity and references to Remote Desktop in my logs and source files.
Recently had to have a FirmWare PW removed from my IMac and I've never set the fw pw in the first place. After the firmware reset when I got home and turned it on first time, tells me it doesn't recognize my administrator /user pws? Can these strange but true issues be related? Am I hacked? If so how do I begin to untangle it all? I did go ahead and set the FW password this time as I don't want anyone else to set it for me and have to go through that ordeal again. Is this something I should do, or not? How else can I protect my IMac, from these rogue changes and settings/menu/program alterations that keep happening. these things seem to happen in spite of several virus, anti spam, security programs I've installed; or any other security steps I've always tried to follow to prevent being hacked.
Started to reinstall Snow Leopard from original disc this evening and Utility tab shows two other volumes installed, that's three total; one being Boot Camp, the other Untitled. I never installed any of these except SL from the original disc. It appears I neither have full access to these other 2 partitions as the i button only shows partial information. Also the verify permissions, users, etc buttons do not allow me to repair, or do anything with these other volumes. Now I'm afraid to try and use the os disc without someone's more knowledgeable guidance, and/or wisdom. I've already made 2 trips to local Apple Store, plus the 3 hour round trip to authorized tech center to get the FW pw reset, so I'm hoping someone on the forum might be able to help me out this time .. argh!HI Suzie,

LAN design - how to implement a core switch?
Hi all,
First post here so please be gentle :-)
I'm looking for a bit of advice with a LAN setup I've been tasked with.
The basic requirements are to have a demonstration suite of servers/storage devices networked with internet access with certain devices segmented in different VLANs. Also, a separate VLAN is required for training and meeting rooms which will receive DHCP addresses from a WIN2K3 server.
The kit I've inherited consists of:
1 ADSL Modem/Router
1 2611XM router
2 Catalyst 4006 switches with Supervisor II engines (CatOS :-( ), one with a layer 3 routing module
Several Catalyst 2950/3500xl switches
Netscreen 100 Firewall
F5 Firepass for VPN
After a lot of fun resetting devices I've currently setup the LAN with a router on a stick configuration which routes between different VLANs (on the 3500/2950s) and which has internet access via the 2611 and ADSL modem router in turn. That's about as far as my current knowledge goes I'm afraid!
What I have to do is incorporate the 4006s but I don't really know how to go about it or what's the best way to use them. How would I use them as core switches?
I was hoping someone could point me in the right direction on the best way to connect the switches up, i.e. network design, cabling (fibre uplinks between switches) and some basic configuration advice with the layer 3 routing module.
Any advice will be most appreciated!! It's my first networking job and I'm a bit lost.
Thanks.Peter,
I would do the same - with a twist...
Have 1 4006 as a VTP server, also the spanningtree root for all vlans.
Have a trunk between the two 4006's - and make it an etherchannel 2 or 3 ethernet links (redundancy).
Make the second 4006 also a vtp server (redundancy) and have that 4006 the secondary 4006 for spanningtree (more redundancy!)
That way if you decide to have a distribution layer - you have 2 uplinks into the core 1 into 4006-1 as the primary, and the second 4006-2 as the secondary.
You could then have a trunk (etherchannel) between the distribution switches, then have a access layer into the distribution layer with duel links. This way you could have multiple switch and or link failures and still work!!!
You use the layer 3 module to do the inter-vlan routing - correct. Then have your adsl modem/router as the gateway to the internet - you put a default route in the layer 3 module point to the adsl modem! then you have the routes for the various vlan subnets pointing from the modem back to the layer 3 module......done!
HTH. -
My friend and I have MBPs and want to set up a network so we can play against each other in XP. Can anyone tell me how we do this?
HI Maakr,
First you want to enable the Switch to Layer3 mode as explained below:
Upgrade the firmware to 1.1.2.0.Use the below link to download the firmware.
http://www.cisco.com/cisco/software/release.html?mdfid=283019686&softwareid=282463181&release=1.1.2.0&relind=AVAILABLE&rellifecycle=&reltype=latest
Configure the switch with below commands to change form Layer 2 to 3
The set system mode Privileged EXEC mode command puts the device into
switch mode (Layer 2 mode) or router mode (Layer 3 mode).
Syntax
set system mode {router | switch}
Parameters
• router—Specifies that the device functions as a switch-router.
• switch—Specifies that the device functions as a switch.
Default Configuration
The default configuration is switch mode (Layer 2).
Command Mode
Privileged EXEC mode
User Guidelines
After executing the command, the Startup Configuration file is deleted and the
device is rebooted. It is highly recommended to back up the Startup Configuration
file before executing this command.
Example
The following example configures the device to function as a switch-router (Layer
3), with QoS and Policy based VLANs.
switchxxxxxx# set system mode router
After this
Kindly check the Menu--->IP configuration--->IPV4 interface---->you add the SVI interfaces for multi vlans.

1. Create two Coherence Servers in Weblogic console. These are cache stores using replicated cache scheme.
2. Create tow Coherence servers which acts as proxy. These should not contain any cache.
Can some body tell me how to create the cache config for the step2 i.e proxy servers? when I created the proxy server without giving the cache names I am getting cache not found error.Hi Sri,
There are various options available for this but...
If I was building this application I would probably make your Web Cluster storage-disabled members of the Coherence cluster (assuming they are Java). This will give them quicker access to data than using Extend. You would then not need the proxy servers. I would use distributed caches in your Coherence storage nodes rather than replicated and then configure near-caches in your Web layer. If you wanted to you could use the resource from the servers that you were using for proxy servers as storage nodes as this would give you a little more capacity and make the cluster a little mode durable - i.e. less prone to complete failure if you lost a node.
So, your coherence-cachestore-config file would look like this
<cache-config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://xmlns.oracle.com/coherence/coherence-cache-config"
xsi:schemaLocation="http://xmlns.oracle.com/coherence/coherence-cache-config coherence-cache-config.xsd">
<defaults>
<serializer>pof</serializer>
</defaults>
<caching-scheme-mapping>
<cache-mapping>
<cache-name>products</cache-name>
<scheme-name>distributed-scheme</scheme-name>
</cache-mapping>
</caching-scheme-mapping>

<service-name>DistributedCacheScheme</service-name>
<backing-map-scheme>
<local-scheme/>
</backing-map-scheme>
<autostart>true</autostart>
</distributed-scheme>
</caching-schemes>
</cache-config>The cache configuration for the Web layer would be similar but have near caching
<cache-config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://xmlns.oracle.com/coherence/coherence-cache-config"
xsi:schemaLocation="http://xmlns.oracle.com/coherence/coherence-cache-config coherence-cache-config.xsd">

<cache-name>products</cache-name>
<scheme-name>near-scheme</scheme-name>
</cache-mapping>
</caching-scheme-mapping>
<caching-schemes>
<near-scheme>
<scheme-name>near-scheme</scheme-name>
<front-scheme>
<local-scheme>
<high-units>1000</high-units>
</local-scheme>
</front-scheme>
<back-scheme>
<scheme-ref>distributed-scheme</scheme-ref>
</back-scheme>
</near-scheme>
<distributed-scheme>
<scheme-name>distributed-scheme</scheme-name>
<service-name>DistributedCacheScheme</service-name>
<backing-map-scheme>
<local-scheme/>
</backing-map-scheme>
<autostart>true</autostart>
</distributed-scheme>
</caching-schemes>
</cache-config>The above near cache would only hold 1000 entries, and Coherence will manage expiry of this. You could tune this figure, other other expiry setting to optimize the data access for your Web layer - as described in the near cache docs here http://docs.oracle.com/cd/E24290_01/coh.371/e22837/cache_config.htm#BABGFCII Storage disbaled nodes with near caches are not always the best approach, but given you are using them in a long-live Web layer and the data does not change very often, I think they would be good for you to use.
As I said though, as with a lot of things in Coherence, there are a number of options available to you, some good, some not so good; the above option is just the one I would choose. Given the requirements you have mentioned there is actually not much wrong with the solution you have chosen apart from access to data is slower as there are always two network hops involved with the proxy in the middle and it would not scale up so well if you wanted to grow the system.

Hi all,
I have a problem with oracle bi-database connection. Currenty when I try to import from ODBC 3.5 datasource what oraclebi shows me does not exist in ODBC connection, and also when I added a new odbc connection to system dsn I cannot see it from Oracle BI. It is like looking to entirely different machine.
Computer is 64 bit windows. I installed OBISE1, in installation both oracle and obi software were installed succesfully but I had a problem when it was trying to create the sample bise1db database(credential retrieval failed). Then I installed 64 bit oracle software, pachted it to 10.2.0.4 and created the database instance(I received the same error when creating 64 instance but I updated sqlnet.ora and I successfully created instance).
I restated Oracle BI services but now Oracle BI is behaving like it is not in the same computer I am looking at. It is not possible to import from ODBC 3.5 because it is not seeing System DSN connections. I also tried to create new database and connection pool and manually configure in the physical layer but still I get connection errors.
Currenty there are two oracle software in the computer, 32bit 10g and 64 bit 10g and only one instance that is created with 64 bit software.
I am not sure it was a mistake to install OBISE1 software to 64 bit machine.
Any help would be appreciated..I assume that when solaris 10 boots up, it only checks the land line NIC card, not the wireless card. If there is no lan connection, then so be it.
Is that right?No! :-)
nwam only supports one device but the device is selectable. physical should activate all devices regardless. So if your Wifi isn't working then I would use wificonfig to see what it can see. Check the man page for scan and showstatus options. Then you'll know what it's seeing.

Two effects - Reverse and split picture?
I was wondering if anyone could explain to me how to do both or either of these effects. For all I know they may be simple to do, however I cannot figure it out.
1. Reverse - How do you take a video and reverse it. Ex: A car driving forward and then switch to it going backwards the way it came.
2. Split picture/video - How do you take a video and split it vertically into say 4 or 5 different segments? For this, I need to be able to show only 1 segment at a time and also all of them at once, so a little black line between each segment would be great if anyone could help with these.
Thanks in advance!1. Highlight the clip, right-click on it and select SPEED. When the Speed window opens, check the reverse box.
2. The easiest way is to create a matte in Photoshop in the configuration you need then layer the matte over the clip.
