Multi-Layer switching & cef

Does anybody have some usefull links or information regarding CEF/Multi-layer switching? How are these features interacting with each other? Key differences?
Thank's a lot.
Florian

Hi Florian,
Basically in MLS the first packet to reach the destination rill need to be processed by router as it just maintain the caches and so for second packet it gets wr writed in hardware.
But in CEF even the first packet is hardware switches as it builds the adjacency table and FIB table. Which not only maintains the routing entried but also the arp entried like binding the mac with ip so that even first packet can be hardware switches.
Have a look at this white paper for CEF

Multi-layer/layer3 switch VS. Router

Multi-Layer Switch or Layer3 switch vs. router; How they are different?
1.7

In a router the route calculation and packet processing take place in the software on layer 3. This means that packets need to be moved from the layer 2 hardware interface to layer three and so it takes some time. In a layer 3 Switch Routing calculations takes place at layer 3 in hardware or software, while the actual packet processing takes place at layer 2. The speed gain is accomplished by reducing the amount of features supported and moving as much logic as possible into hardware.

Is it recommended to use HSRP or multiple default between Core Layer Switch and Customer Edge Router?

My client is asking me for following
Client is using Router as edge device. 2 WAN links from different service provider ( each 20 Mbps) are getting terminated on the router. There are internal servers present in the network. Client want to make setup such that even if one wan link fails internet users should be able to access web server. Moreover if the edge router fails there should be secondary edge device so that there is device redundancy ?
As per my understanding, in this scenario we need to do static one - to - one natting(belonging to WAN interface subnet). If we use two routers as Customer edge ans if we connect core layer switch to these two router, is it recommended to use HSRP/VRRP/GLBP or two default route on core switch pointing to two routers with equal ad value. we will also track the wan link with help of ip sla.
which is recommended solution Router redundancy protocol or Default routes.?

Just had another read of this post and some other points have come up.
1) I assumed your secondary link was for redundancy but you talk about terminating both SP links on the same router in your first paragraph.
Did you mean this or are you going to be terminating a link per router ?
2) are you using the second router purely for backup ?
3) something you didn't ask about but is relevant is the IP addressing. Are you using provider independent addressing or does each SP provide you with an address block.
If it is the second then you are going to have an issue with the web server. The problem is which provider's IP do you use for the web server ie.
if you use the primary provider IP then that will be the DNS record on the internet. If the primary router fails then the IP address will change on the secondary router but DNS will still be handing out the primary IP.
If you enter both IPs (primary and secondary) into DNS then you would get load balancing but this means both links will be used and the secondary would not just be backup.
In addition if one of the links fails then DNS does not know this so it will still be handing out the failed address as well as the address that is still up which means some connections will work and some won't.

Creating Vlans at Core layer switches ?

Is there a need to create vlans at core layer switches ? If yes what are the pros and cons for this practice ?
Actually i have seen some networks doing that!

Well this is the topology that i'm working on.
we have implemented the 3 layer approach.
1. At access layer: Switches are all L2 (for sure :) )
2. At distribution layer: All switches are L3 are routes for incoming data.
3. At core we have 2 6500 switches. One is configured as L3 and all vlans are created in it. Second is just as regular L2 device.
and ofcourse there are some switch blocks for server farms and the likes.
My issue is
1. why don't we create vlans at distribution layer switches.
2. Why one core switch is acting as L2 and other is acting as L3. What will happen in case of failure to the one acting as L3.
Ps: the second issue just came up in my mind.

IPad - view multi-layer PDF?

On an iPad, how can I view just the text layer of a multi-layer PDF?
I have a PDF which has 4 layers. They are all visible at the same time through the Adobe reader app.
This is un-readable. How can I select just one layer to view at a time?

I found a post that Fuji Xerox Docuworks Viewer Light reads PDF layers but I could not verify as it's not sold in the USA App Store.

Multi-layer filter

It's possible to make a multi-layer filter plugin? The idea is: the user has open a multi-layer document, then execute the plugin and selects N layers of the document in the filter UI, and when clics "OK", the plugin create a new layer adding every selected layer pixel by pixel.
LAYER A             LAYER B                      RESULT LAYER
0 0 5 5 5                1 1 2 1 1                           1 1 7 6 6
0 0 0 5 5       +       1 1 3 1 1            =             1 1 3 6 6
0 0 0 0 5                1 2 3 2 1                           1 2 3 1 6
Any advice?
Thanks!

A filter plug-in can read from any layer using the channel ports suite. See the Poor Mans Type Tool example. A filter plug-in can only write to the active layer. You cannot add a layer from a filter plug-in. You would need the auto/filter combo as Chris talks about. See the autofilter/hidden combo example or the format/auto for importing text files example.

Core layer switches IP address for routing

For routing process I add a IP address of each Vlans subnet that active on each Access and Distribution switches (Have a port with that Vlan on the switch) to the corresponding Vlan Interface of them.
Which IP address should I add to the Core switch for routing?
Should I add a IP of each vlan that in the LAN to each vlan interface of Core layer switch?
I want run OSPF routing protocol on the LAN.

Hello Reza,
>> Which IP address should I add to the Core switch for routing?
if you want to implement a L3 routed core every link betweeen core device and a distribution device is a L3 link with its own IP subnet.
For example if you have 16 distribution pairs and two core switches:
10.10.10.0/30 dis11 to core1
10.10.10.4/30 di12 to core2
10.10.10.8/30 dis21 to core1
10.10.10.12/30 di22 to core2
10.10.10.128/30 disF1 to core1
10.10.10.132/30 disF2 to core2
this under the idea to have not a full mesh between core routers and distribution devices
then you need also a L3 link between the two cores (at least one)
Each L3 device should also have a loopback interface to be used as OSPF router-id and for management purposes (telnet and so on)
you can use /32 loopbacks taken from same block for example
10.255.254.1/32 core1
10.255.254.2/32 core2
10.255.254.3/32 dis11
10.255.254.4/32 dis12
to make the routing function the core switches have to talk OSPF on all links to distribution nodes
router ospf 10
router-id 10.255.254.1
network 10.10.10.0 0.0.0.255 area 0
network 10.255.254.1 0.0.0.0 area 0
network area commands work like ACL statements and first statement starts OSPF on each interface whose ip address belongs to 10.10.10/24 space
Second command is used to advertise its own loopback.
router-id command allows to define the OSPF router-id.
Distribution nodes have to advertise client Vlans and to take part in OSPF communication on point to point link.
if you use a L2 access layer design client vlans are served by distribution nodes.
if you use a L3 access layer design the access layer switches take part in OSPF and have to advertise their own client vlans.
Hope to help

HT4211 I would like clarification on the official intended usage of the multi-tasking switcher. Specifically, should apps be regularly closed (minus bubble) out of this list, or is the close feature closer to OS X's force quit.

I would like clarification on the official intended usage of the multi-tasking switcher. Specifically, should apps be regularly closed (minus bubble) out of this list, or is the close feature closer to OS X's force quit.

It is not really necessary to close apps from there. It is more like a recently used apps list. You can close them from there if a problem occurs with the app, and there are only a few apps that will remain running when you close them with the Home button. You can see information about the multi-tasking bar in the User Guide. http://manuals.info.apple.com/en_US/iphone_user_guide.pdf

MSTP on Access Layer Switches

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,
Terence

Hi,
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).

Why access switch has flapping lead another distribution layer switch has root guard blocking and unblocking log

is it misconfiguration in Access Point's access switch or hacker attack from this switch?
many MATM-4-MACFLAP_NOTIF Host 0015.5dc1XXX VLAN 1 is flapping between port 1 and port 2
many MATM-4-MACFLAP_NOTIF Host 0015.5dc2XXX VLAN 1 is flapping between port 1 and port 2
many MATM-4-MACFLAP_NOTIF Host 0015.5dc3XXX VLAN 50 is flapping between port 1 and port 2
many MATM-4-MACFLAP_NOTIF Host 0015.5dc4XXX VLAN 50 is flapping between port 1 and port 2
last time we do not have these switch also meet the same issue about distribution layer switch have many ports down
last time someone mention a switch lost config, but today, i remember that the switch has reloaded and can be login again with radius,
today i do not connect any notebook with this switch and just have configured radius setting for window NPS radius server and then reload, then
i have dinner and come back and after a while, last time's issue happen again.
it seems port channel easy to have problem when abnormal traffic coming from access switch result in down port in distribution layer switch
i wonder whether someone can hack through the switchport access mode port and send some broadcast message

From that output and your description it looks like you have an STP issue as a result of misconfiguration somewhere.
Are your access points connected to switches with ports in access mode or trunk mode?

__Is there a way to make a multi-layer Ai file into a multi-page PDF? (1 layer per page)

__Is there a way to make a multi-layer Ai file into a multi-page PDF? (1 layer per page)
thanks

Definitely can be done.
In CS 4 you create an artboard for each page and the position the art for the corresponding page on the corresponding artboard and make a layer for that art. This way it does not even matter if the layer s are properly layered when saving the pdf. Just as long as the artboards are.
CS 3 and earlier back a larger document that can be divided into whole pages by turning on tiling and using the page tool position that art.
Position the art for each page over the designated artboard make a layer for each pages art now when you export the with tiling on and you wll get a multi page pdf.

Do I make more then one diagram in Multi layer design Diagrams?

Do you make more then one Diagrams for Multi layer diagrams?
develop the multi layer design. ?
So I had to make a SSD or sequence Diagram now we have to make a multi design diagram?
for the multi design. will we just be creating one big diagram of the assignment for this part?
or is it going to be a collection of a bunch of separate diagrams. as books shows a few of them? regarding layers?
For example create a diagram to cover all different layers/steps
So should be a collection of 3 or more diagrams for Part 3 of TMA3
do I have this correct?

Just click on "Buy" one at a time. If you do them all in one sitting, they will be grouped as a single charge on your credit card.

Multi-Layer Cache Servers

Is there any other way to configure multi-layer cache server client select other than with IP addresses?

It might lead to replication conflicts if people in the branch offices
do administrative changes to AD. But unless replication resumes within
the tombstone lifetime, this is not a critical issue.
The only point in fact is tombstone lifetime (and of course, Sysvol
replication -> DFSR maxage).

Packets dropped to Access layer switch???

We have a 6509 running in Native IOS that has 2gb port channels connecting to our 7 access layer switches. About a week ago we were working with Remote span vlans and added a remote span from the 6509 to our other core (6513) which is connected via a 20Gbps portchannel. We began to notice that a lot of people were calling in reporting devices as being slow and we noticed that from the 6509 (Which was the root bridge) we were disgarding millions of packets on the transmit side of our access layer switches. We took out the remote span but it appears that we are still disgarding packets. There are no input or output errors on either side. The Remote span VLAN does not exist on the access layer switch's VLAN database. Does anybody have any idea what we should be looking for?

you can use an acl to match the number of packets that come into / out of each of the devices. Simply use two lines in each acl where on the first line you match the packet in question and on the second line you have "permit ip any any" so you don't block any packets. Then simply apply the acl either inbound or outbound on the interface in question. If you want more than one acl on a given device, such as inbound one interfaceand outbound another, be sure to use two different acl numbers.
create the acl's and apply them
ensure there isn't an active call
clear access-list counters on all devices where you configured the acl's so we ensure all of them are set to 0

PS CC 2014 Slow Layer Switch

I am running PS CC 2014 on a 27 inch iMac. My version of PS is up to date. But I've been having problems with sluggish performance for three to four days.
I try to switch between layers using the shortcuts and it's really slow. Even when I switch to an adjustment layer, the properties tab takes almost a second to load. I even re-installed a clean copy of OS X 10.9.4. But I still have the same issues.
I am totally going insane now. I really hope to fix this issue.
My System :
Processor 3.2 GHz Intel Core i5
Memory 24 GB 1600 MHz DDR3
Graphics NVIDIA GeForce GTX 675MX 1024 MB
Has the current versiona of Photoshop, Lightroom and Bridge.

Here's the thing. I don't have any other extra plugin installed. To eliminate any OS issues, I installed a clean copy and then used photoshop without installing any other softwares. Just my OS X and Photoshop without any modifications.
But still, I have the same problem. The other thing is that, when I use alt +[ or ] to cycle layers, it's slow. If I save the same thing as an action and run the action, I'm able to switch to another layer instantly.
