LACP or Link State Tracking over VPLS?

Hi all!
I have 2 sites connected with VPLS. Both sites are now having a 2nd VPLS circuit installed (with a different carrier) for redundancy/failover. I've got a Catalyst 3750 at each end to work with.
My question: what's the best way to configure the 3750's? I was thinking either LACP with 2 physical interfaces (one for each VPLS line) - in which case traffic would be balanced across them, which is fine.
OR I could use Link State Tracking, such that if 1 link fails it would failover. Though I'm new to Link State Tracking so I don't know if this would actually work over VPLS.
Your thoughts are very appreciated.

Link state tracking, also known as trunk failover, provides Layer 2 redundancy in the network when used in conjunction with server network interface card (NIC) adapter teaming. Link-state tracking is used to mirror the state of the ports that carry upstream traffic from connected hosts and servers, and to allow the failover of the server traffic to an operational link on another Cisco Ethernet switch. Check out the following link for more information on link state tracking :

Link State Tracking in Cisco ASA

Dear ASA Guru,
Is there any feature like Link State Tracking in Catalyst for Cisco ASA. I want to shutdown another interface if one interface is down in Cisco ASA.
Best Regards,

Link-State Tracking?

Attached is a diagram of my fabric I will be deploying (data center environment). The access switches are 2960G (24port), and the distribution switches are 2960G (48port). A total of 18 access switches will be used.
I will be using Rapid PVST+ throughout the fabric. With that in mind, is it necessary to implement link-state tracking on the access switches as well? I am having difficulty finding out if Cisco recommends link-state tracking for performance improvment, or if it is absolutely necessary in my environment.
What exactly are the pros/cons of enabling link-state tracking on my access switches?
Thanks,

Link-state tracking on 3550

Hi,
I would like to know if the link-state tracking is supported on the 3550. If yes then please let me know on which IOS version. I was not able to check this on the IOS features.
Second question:
Can I trak on sub-interface (VLAN) instead of the full interface?

Hi Amin
I checked out for the same and it says its supported in Cisco 3550 but regarding the exact ios code you better can choose the required version from the feature navigator.

Link-state protocol on blade switches

Hi,
Can anyone confirm is after an uplink is reestablished the down stream interfaces are automatically restored when using link-state protocol?
The documentation states the downstream ports in a group are put in error disable state but doesn't say if they are automatcally made up when the upstream interface comes back up. This refers to Cisco blade 3020 switches running 12.2.25

REP common link over VPLS

Hi,
I'm looking for some guidance on how to configure a REP common link over VPLS. I've read a bunch of docs that more or less elude to the fact that it should be supported, but no combination of documents thus far have clearly outlined what the prerequisites are in terms of software, ES vs. ES+ hardware or relevant configuration glue to make this work.
http://www.cisco.com/en/US/docs/ios/lanswitch/configuration/guide/lsw_cfg_rep.html#wp1316104

Cisco Live 2010 session BRKSPG-2205 (Deploying and Designing with Resilient Ethernet Protocol) page 79
I've got two 7600/SUP720/SRE5 boxes with a chain of ME3400s connecting the two over 6724 LAN based linecard ports. I've also got an ES port between each 7600 to carry the SVI based EoMPLS foo between the two, and this is where I'd like to establish the VPLS common link (hopefully the below ASCII diagram will show up OK):
[ 7600-1 ]--(6724-GE)--[ ME3400-1 ]--[ ME3400-2 ]--(6724-GE)--[ 7600-2 ]
   |                                                               |

   +---------------------------(ES20-GE)-------------------------- +
In terms of config, I've got the 6724 chain side configured as a REP segment and the REP admin VLAN is 1/default. I haven't been able to find the configuration glue needed to make REP aware that the common link for the segment is the VPLS pseudowire between the two 7600s:

However in a REP segment failure, the pseudowire seems to be pretty much useless acting as a common link for the failed segment.
Is anyone running a config like this? Am I missing something obvious (or not so obvious?)?
Thanks in advance.

Is there a way to link state buttons?

Hi, I'd like to know if there's a way to link state buttons to activate their hover state together. For instance, when the link 'Pioneers of Design' is hovered over it turns red and links to another page. The yellow image loses the 25% white opaque screen on it when it's in hover state and also links to the same page. Both are in separate state buttons. Is there a way to link the two so that when I hover over the image the screen disappears but also turns the pioneers link red at the same time and vice versa when hovering over the pioneers link? I know both can be put into a state button together but that means that the massive space in between the image and text would create the hover state as apposed to only occurring when hovering over one or the other. Also, I don't know what would happen to this because the text links stay fixed when scrolling and the image links do not. Is there a way to do what I'm talking about? Thanks.

There's no built-in way to do disjointed rollovers, but if you look it up on the web, you should be able to understand how the respective CSS rules work and implement them as custom HTML or after publishing the site.

VIF link state down

Hi
When I configured service profile to a blade then deploy ESXi, It works correctly for a time then I found the following error " VIF 716 link state is down" as in the attached and the server management IP is pingable also the ESXi IP is pingable during the error
I did the Same to another blade but no problem

Hi Amr
This has been discussed many times before
see eg. https://communities.vmware.com/message/2183957
But about the HW failover configuration I really do not know why not recommended to use the HW failover I think it's better than failover of VMware VSS
Agreed that it should work, but I'd prefer to enable and configure failover behavior in ESXi rather than UCS. In my research on this issue, I found a thread over on the Cisco UCS forum that has a clear statement regarding this configuration: https://supportforums.cisco.com/thread/2187653.
"Never use fabric failover with a hypervisor vswitch. Let the failover mechanism of the vSwitch handle the network outage."
So while it may be a valid design, it looks like the consensus is to let your vSwitch handle the failover.
Cheers

STP over VPLS

Hi Everyone!
I have a scenario of 3 PE routers with full mesh VPLS Pseudo-wires configured over it. If you look into the design, I have connected two switches Sw1 and Sw2 with the PEs R2 and R3 respectively. Considering that the VPLS cloud is operating correctly, I have connected a CE switch [Sw3] with Sw1 and Sw2. Now, the issue is STP over VPLS. Without having STP running inside the VPLS cloud, it's causing loop all over the ring.
In order to avoid loop, I have run PVST+ on all the three switches but the PEs are not running STP as I believe that the BPDUs are to be transparently forwarded through the VPLS pseudo wires. But, i'm not really sure why i'm getting PVST_Inc error on both Sw1 and Sw2 for the links that are connected with their respective PEs. Any response regarding this will be highly appreciated.
For your reference, network diagram is attached below:
Thanks!

What kind of PE routers do you have? Are they ASR9k running EVC/EFP on switch facing interfaces?

Physical statement tracking. Is it possible?

Hello list
Does anyone know if is it possibile to set up physical sql statement tracking using connection scripts (in OBI 10.3.3.1) ? I can use usage tracking but actually I'd like to know what sql query is executing in database and link it with usage tracking. Maybe OBI sets some variables that can be used in connection sripts.
Thank you in advance
prom

I would like to insert sql physical statements automaticly in a table (just before execution). Then join them with usage tracking to see them on dashboard. Actually in OBI 10.3.3.1 you can write your own connection scripts, I've found that I can access some variables in tihs scripts (eg: :USER, :PASS :), yes you can set password logging :) (even from LDAP - I think It's big security hole)). It's not documented well, so I only suppose that there exsists variable that holds physical statement. If anyone can give me any clarifcation or point any link to the documentation.
Merry Christmas

Routing loop avoidance in Link State

"The link state method is not susceptible to routing loops which is an advantage over the distance vector method" Why? How it avoid routing loop?

Link-state protocols like OSPF use reliable flooding mechanisms to ensure that all routers are acting on the basis of the same information. Loops occur when routers act on the basis of inaccurate or old information. That is what link-state protocols avoid. All routers in a link-state database have the same view of the network.

More than one style for a single link state?

RH 8 outputting CHM
Hello,
Is it possible to define more than one style for a single link state?
For example, I would like a link in the footer of my master page to be smaller than the links that appear in the body of my topics. I want to retain behavior, and simply change the point size.
I can't simply hand format in Design mode, because my link is within a script. Or, am I missing something easy here?
Thanks much.

I'm pleased to say I figured out how to change the formatting of a hyperlink embedded within a script.
Within the script, I used a var string to reproduce the text in my link. Then I used another var to change the string size.
So, here's the part of my script that produces what I'm after:
var mailDisplay = 'Was this information helpful? ';
var str = 'Was this information helpful?';
var mailDisplay = str.fontsize("1");
Upon generation of the CHM, the script trumps the CSS. It's a beautiful thing.

How to link 3 tracks or more ?

Hi there,
I have a new problem.
I used 2 different camcorder to film the same scene but each from different angle. I also record the voice separately.
I placed the 2 videos on V1 and V2 and the sound on A1 and A2.
I managed to sync the video V1 and video V2 with the sound A1 and A2. To to make sure they are at the correct location, I want to link all of them up
But I cannot linked all these 3 tracks [V1, V2 and (A1 & A2)] together. I can only link either V1 with (A1 & A2) or V2 with (A1 & V2).
Any ideas ?
Thanks

Thanks David,
I need to link them because I am worried I might move them accidentally. After all the hardwork of synching the audio & video, the last thing I want is to move the track ...
Is there no way to link 3 tracks ?

How to restore visited link state to unvisited

Hi all -
I have a pseudoclass which nicely shows a gray background
after being
visited.
After clicking in ie6 browser, the links remain gray forever!
I am unable to view in the pre-visited state to show a client
sitting next
to me.
I am viewing on my local machine
There are no cookies being set
Flushing cache doesn't do it
Closing browser doesn't do it
Even rebooting the machine doesn't do it
I guess my question is, "where is my WinXP machine
remembering the visited
state?"
Anybody know this one? Many thanks
CSS follows
a.inactive
{border: 1px solid #000000;color: #000000;text-decoration:

I accidentally eliminated my "Linked Selection" button over the timeline. How do I get it back?

I'm finding it difficult to understand what you eliminated. Are you saying you no longer see your clips at the upper left of the screen ... the ones you placed in the timeline? Or are you saying you see the clips from the events but not the event names on the left most border of the upper left of the screen? There is a little arrow that points to the left with a bar to the left of it midway down the left border of the screen. Clicking on this little arrow hides or reveals the event names you have. (see below). Can you give us a little more info? Best wishes.
