2n+1 redundancy with 2x5500's + 1x4402

Is it possible to have AP's on a 5500 controller failover to a 4402 if they're running the same software version? Will the AP's try to update their code upon failover?
(this isn't my design, but I might be forced to implement it if it's possible).
TIA

Yes, you can have AP's failover from the 5500 to a 440x, and if the controllers are running different codes, then the AP will pull the correct code for the WLC that it is attached to.
There is no difference between how the controllers support the AP, just the number they can support, platform features aside, i.e OEAP, guest anchoring etc.
Now, if you are working to have redundancy, you should have the controllers on the same code, and if you are using AP groups, the group settings need to match across the controllers as well.

N+1 redundancy with 2504-HA

Hello,
I have question regarding N+1 redundancy with 2504-HA WLC.
Can I use 2504-HA unit for H+1 redundancy? SSO is not needed
I have two wireless network:
1. With WLC 5508 with about 40 AP(1262), all them are A regulatory domain
2. With WLC 2504, with about 30 Mesh AP(1552), all of them are E regulatory domain
I plan to use two 2504-HA units for backups, one for network with WLC5508 and second for network with WLC2504.
In case N+1 redundancy is management with Prime mandatory ?

Hi,
Better to use same model and same software.
Case1: You have 5508WLC
Solution from my side: You must buy a another WLC with HA SKU license(Zero AP license). This wlc can work as N+1 and AP SSO as well as Client SSO but with higher version of code(7.5 or higher).
Case2: You have 2504 WLC
Solution: You must buy a another 2504 HA WLC: AIR-CT2504-HA-K9, that only supports N+1(No AP SSO and NO Client SSO)

Nexus 7000 Switch Fabric Redundancy with Fab-2 ?

Hi all,
I know that N7K did not have N+1 Switch Fabric redundancy. It is required to have all five SF modules to provide full throughput. Does this change with FAB-2 modules ? I mean with new modules, does N7K have N+1 SF redundancy ?
Thanks in advance.
Dumlu

The N+1 fabric redundancy will depend on the type of module.
If you are using M132 (80G) per slot and you have 3x FAB-1 (46G each), it will provide N+1.
The same story applies to FAB-2. If you are using the F1 series, and have 4x FAB-2, you have N+1. Of course, if you are using F2 series linecard and have all FAB-2 populated, you don't have N+1 because F2 is 480G and all 5 FAB-2 will give you 550G.

Redundancy with GWIA

We currently have the following environment:
1. Groupwise 2012 server #1 on one server, with GWIA, MTA, POA,
WebAccess on that server. Primary MX record points to this server. On
our dsl internet connection
2. Groupwise 2012 server #2, GWIA, MTA, on that server. Secondary MX
record points to this server. On our cable internet connection.
Currently, For incoming purposes, email normally comes in via the
primary MX record to server #1. If it is not responding, email incoming
traffic goes via the secondary MX record to server #2. m This is automatic.
However, I am not certain that the outgoing emails have automatic
redundancy. If the GWIA on server #1 cannot process outgoing mail
simply because the dsl internet connection it uses is down, does the
outgoing emails automatically get routed to server #2 to go out that
GWIA. Or does that automatic rerouting occur only if the GWIA on server
#1 is actually down.
I had read that the redundancy routing of the GWIA to server #2 did not
work on GW6, but did work on GW7. Is that the case and does it work
automatically for GW2012 in the instance where the GWIA on server #1 is
still up but is not able to connect to the internet because the internet
connection is down.
We want to have automatic outgoing GWIA redundancy in addition to the
incoming GWIA redundancy.

What would be the proper configuration to provide for this outbound
redundancy if the GWIA itself is actually down?

Redundancy with dual nic servers

Hi I have 2 11500's configured with box-to-box redundancy. I have a number of app servers each with dual nic's (which are Teamed) and which are connected directly to the CSS's. Nic 1 in each goes to the master CSS1 and is therefore live. Nic2 goes to standby CSS2.The CSS's are connected two 4500 switches to the public.I am monitoring the links to the 4500's,if i switch off the master CCS1,we fail over and the servers all connect via nic2 to the new master CCS2. But when the link to the 4500 from the CSS1 Master goes down the CSS'S failover but the nic2's do not connect to the CCS2 because Nic 1 in each server has not failed ie they still see CSS1 as up. Is there a workaround to this problem ?
Thanks
J

I know of no way to link CSS interfaces so that if the uplink goes down, the the other ports are shutdown. There may be another way to configure the adapter teaming or failover on the server side. I know some OS's send out test frames from one adapter to the other to verify network integrity.
What I'd recommend is that you setup a VLAN on your 4500's for the server's physical connections, and uplink that to a "backend" interface on the CSS. This can be done with the CSS in either a router or bridge configuration, but I'd recommend router mode.

How to implement redundancy with RT cFP?

Hi all!
I have a setup with a cFP-2020 controling a pump and multiple switch valves. The controller runs a PID that regulates the flow.
It also communicates with a pc through TCP/IP. A user can drive all the setup manualy ( opening/closing valves, change flow
setpoint, reading pressure sensors values,etc) and also launch an automatic mode that folows a recipe created by the user.
I would like to implement a redundancy at various levels:
1) Power : It is solved by the cFP itself since you can feed 2 power supplies.
2) Controller : I would like to add a second controller that would monitor the primary controller and takes over the control if
                       primary controller crashes. I know there is a hardware watchdog that would help a lot in the task.
                       I would know when the primary controller crashes through that watchdog. But how to know the final state where
                       the controller crashed so that the secondary controller would start from there? If it is in manual mode, it would be
                       easy, I could initiate the secondary controller with the last state on the host (pc). But what about automatic mode?
                       I could store the variables at any time but isn't it a bit too much? Is there a way to retrieve those data, other than
                       sending it to the host computer?
                       Does anybody has a good idea / structure in mind for this application?
3) Fieldpoint I/O: I would like the same as for the controller: have a second set of DI, DO, AI and AO that would secure the system.
                           There is also a watchdog there that could be used.
The main goal is, in fact: Let's say you remove physicaly the controller or any Fieldpoint I/O and the system would seemlessly go
                                         on his task.
Anybody already did that before?
Thanks for any help!

LV 7.1 - WIN XP - RT - FP

Hi and thanks for the reply!
In fact, for the moment, when the connection to the pc is lost, the controller goes into "safe mode". It is a state where I am sure
there is no security issue for the person running the process ( avoid over-pressure in different tanks, etc).
I did not described the current process using the cFP because this one is less critical in terms of redundancy. If the process
is stopped because the connection is lost for example, it is not so important. The process can still be restarted from the very start.
It is because the process (chemical) allows it. It is like filtering. If half the filtering is done, you can still filter again to get the proper
result.
I am thinking about another process much more critical. If the process is stopped, it is lost. And it means a lot of money tens of 1000 euros at once.
For the moment, those processes are regulated and operated from a DeltaV DCS system (Emmerson). It is reliable but expensive and the programming environment is poor. I really like Labview. It is really powerfull !!!
In the future, if possible, I would like to replace the old systems of our plant with NI ones. I think it is much better when you have
a homogenuous system. Having a network with pc's, mac's and linux's is much more difficult to set up and maintain. The same
for the field, it is much more complicated when you use at the same time: labview, deltaV, profibus, foundation fieldbus, CAN, etc.
Of course sometimes, you cannot avoid it. The systems are different and have their pro's and con's... Of course, it is just my opinion!
If it would be possible, I'd buy only NI stuff... Now, I just replace if possible.
About the the Outputs being redundant, I was thinking about a polling system: use 3 outs and poll. The majority wins. It think it is used on space applications.
So, I should have asked at the first time : Do you think it is possible to replace a DeltaV system with a NI one?
I think it is possible. But is the effort worth it? If I have to code all that? If there was something built in, it would be a dream
Okay, thanks anyway. Maybe I need to think about it a bit more.

How to implement redundant with 1 CE router to 2 MPLS service providers

Dear all,
Our head-office are currently have 1 Cisco CPE 3825 router with 2 WAN connections to our branches. We are now using static routing protocol in our network infrastructure, we consider how to implement the redundancy for networks by the redundant circuits connection to 2 MPLS providers, only when the primary connection to the primary MPLS L3 provider fail, the backup link to the second MPLS Layer 2 provider automatically active. Anybody knows where can I find information, tips or examples, how we'd handle the routing for that?
We are now have:
1 G0/1 interface connect to primary MPLS L3 Provider (the 2nd G0/2 interface is a leased-line connection to our partner, and we not consider here)
1 HWIC (layer 2) card, with 4 ports, which has interface F0/2/3 connected to the backup MPLS Layer 2 provider.
Thanks in advance.

Hi Mr jianqu,
Because of our customer now has 2 main central offices, and all other sub branches are now connected to each of these main central office via one primary full-meshed MPLS VPN of 1st Service Provider, so If I use the float static routes, and when there is a failure at one link at a CENTRAL CE Router to primary link to primary MPLS VPN Service Provider, but still there is no failure at the other site from a router CE sub branch with the the PE of the primary full-meshed MPLS VPN Layer 3 Service Provider,so It cannot cause a failover to a second redundant link of the 2nd Service Provider?
So with our system, do we only have one solution like this:
-Configure BGP as the routing protocol between the CE and the PE routers.
-Use local preference and Multi Exit Discriminator (MED) when running BGP inside a our customer VPN to select the primary and backup links.
-Use AS-override feature to support overlapping AS numbers between customer sites

WLC redundancy with prime

Hi all,
We are going to implement high availabilty in 5508 WLC with version of 7.3.101 . We will be using Prime infrastructure 1.2 for monitoring purpose.
With Prime , whether we can monitor and manage redundant WLC also or only active WLC?...
Thanks for your help.......

I just know from experience. You can only GUI/ssh into the primary WLC when you enable AP-SSO. So once the pairs are in HA, that is it.... You have only the primary WLC IP address available. You learn things the hard way sometimes because there are things not documented.

Redundancy with 2 vWLC

Hi Forum,
is it possible to operate 2 vWLC (with version 8.0) and configure them to work redundant (in any mode A/A, A/P or cold stand-by) as you could with a 5500 WLC?
TIA
Alexander

Hi Alexander,
Yes that is possible, but not in an hitless fashion like SSO with the 5500 controllers. The access-points need to determine that their primary controller is down which will take at least 10~15 seconds (if you are going to use fast AP heartbeats). And all the clients need to re-authenticate. To answer your question; just configure an primary and secondary WLC on the access-point.
With the virtual WLC your access-points have to run in FlexConnect mode which has some drawbacks (just like the virtual WLC itself, comparing it to an physical WLC). But depending on your deployment, the virtual controller can be much cheaper and lift on the HA infrastructure in the already existing hypervisor layer in your datacenter.
It is also possible to do "local authentication" on FlexConnect AP's when the connection to the controller has been lost, which can be handy when the WAN link is instable. Maybe this feature is an better solution that just add an second WLC in the datacenter far away.

Redundancy with dual WLC

Hi, I will implement a WLAN network with AP1130AG and WLC 2125. If I understand right the whole traffic to/from the APs (data + management) will be first encapsulated in a LWAPP tunnel to/from the WLC ? Then, the WLC will forward the different traffic VLANs via a 802.1Q trunk to the network. Is it correct ? If so, the WLC is a true single point of failure ! What will happen if the WLC get out-of-service ? What is the impact on existing client sessions and new ones ? How will a redundant WLC 2125 work with the primary (active/standby with HSRP, load balancing)? What are the best practices in such a network ?
Thanks

Hi Jean-Pascal,
In the WLC world this is how an AP is covered in case one WLC fails. It is not without some "downtime" in case of failure but both Controllers are active. You have to keep in mind that an AP can only be registered to one WLC at a time so this is the best that you can do :) When one WLC fails the AP then has to re-register with the backup, this is not a completly seemless process.
This has some really good info;

Ace redundancy with different software licences

Hi,
We have 4710 with ACE-4710-1F-K9.
1G Bundle: Includes ACE 4710 Hardware, 1 Gbps Throughput, 5,000 SSL TPS, 500 Mbps Compression, 5 Virtual Devices, 50 Application Acceleration Connection License, Embedded Device Manager
We have another 4710 with ACE-4710-2F-K9.
2G Bundle: Includes ACE 4710 Hardware, 2 Gbps Throughput, 7,500 SSL TPS, 1Gbps Compression, 5 Virtual Devices, 50 Application Acceleration Connection License, Embedded Device Manager
Is that possible to make redundancy (FT GROUP) with 2 devices has different software bundles?

Hello-
When you initially setup the ACE's in an FT pair, they initially figure out who is master based on priority, then they check if the licenses that they each have installed are the same. If there is a mismatch, FT will continue to check the configuration and will eventually go into a "standby warm" state. It will not config-sync the startup or running configurations until you install the correct license and toggle config sync.
This is what yo uwould see:
ACE-A/Admin# show ft group 1 status
FT Group                     : 1
Configured Status            : in-service
Maintenance mode             : MAINT_MODE_OFF
My State                     : FSM_FT_STATE_ACTIVE
Peer State                   : FSM_FT_STATE_STANDBY_WARM
Peer Id                      : 1
No. of Contexts              : 1
Running cfg sync status      : Detected license mismatch with peer, disabling running-config auto sync
Startup cfg sync status      : Detected license mismatch with peer, disabling running-config auto sync
If you disable config sync, it will still stay in a warm state and ignore the license mismatch:
ACE-A/Admin# show ft group 1 status
FT Group                     : 1
Configured Status            : in-service
Maintenance mode             : MAINT_MODE_OFF
My State                     : FSM_FT_STATE_ACTIVE
Peer State                   : FSM_FT_STATE_STANDBY_WARM
Peer Id                      : 1
No. of Contexts              : 1
Running cfg sync status      : Sync disabled by CLI.
Startup cfg sync status      : Sync disabled by CLI.
It is not recommended to run with 2 different licenses because it is possible that you failover and don't have enough resources to carry the traffic that the active was running - however - if you disable configuration sync, it will allow you to do such.

Chris Higgins

VPN Redundancy With Same Peer

I have 1 ISP-A line in SiteA
Peer : 10.10.10.10
I have many S2S Tunnels between my SiteA - RemoteSites, i have redundancy when there is a hardware failure in SiteA, but if the ISP link fails there
there is no backup.
If i take another ISP-B i will get diffrerent IP Adress than ISP-A, but my RemoteSites are not agreening on configuring Second Peer as backup.
So what is the way where the VPN tunnel should work with ISP-B with same Peer(ISP-A:10.10.10.10) if the ISP-A is donw.

Hi,
I see sorry. I haven't read through this article properly so apologies if it doesn't cover what I say it does.
But I believe you can also (again IOS version dependant) track ICMP availability. E.g. can I ping www.cisco.com? If yes its up if not fail over. You can configure timers etc. Obviously this adds a slight overhead in terms of traffic.
http://www.cisco.com/en/US/docs/ios/12_3t/12_3t4/feature/guide/gtfhrp.html
The other way I believe you could go about it is configuring the two routers with IPsec High availability and detect the dead peers with DPD. I don't have any config etc to hand I am afraid but a search on IPsec High Availability may turn something up.
Thanks

[ios pw redundancy with xr mc-lag termination]

hi, all:
first of all, thanks in advance and please take a look at the attached diagram.
i'm trying to setup a pseudowire redundancy setup between an ME3800 and two ASR9000s that build a mlacp etherchannel towards a cat4500, 4500-2. when primary pseudowire is up, everything works as expected. the problem is that, when you cause a switchover scenario from the primary asr9k-1 (say by shutting down the link to the 4500-2) to the secondary asr9k-2, traffic does not pass from one end of the pw to the other. if we bring up the failed link back up, primary pw works.
all 'show' commands checkout and pw switches over as expected. as a test, i have a 3rd asr9k connected in parallel to the ME3800 and we have no problem with that. when we cause the exact same failure scenario, the primary pw switches over to the secondary and everything works exactly like i would expect. traffic passes in both pri and stby pws when using the parallel asr9k.
as you will be able to see from attached-configs, the pw's from ME3800 and asr9k are a little different. ME3800 pw is port-based and asr9k pw is vlan-based, but since both primary pws work i see no obvious problem with that.
now, i know both ends of the mc-lag work, because the asr9k pw redundancy setup works.
if i build a single pw (no redundancy) from ME3800 to asr9k-1 connecivity works AND if i build a single pw from me3800 to asr9k-2 on same exact vlan, connecivity works also.
hopefully, one of you will take the time to look at configs and let me know if you see something wrong (i think with the ME3800 config). please keep in mind that everything works perfectly when working with asr9k pw redundancy (xr on both ends of pw)

hard to tell where and why the traffic gets dropped if I were to guess the me might send traff still down the wrong PW
due to mac learning so it might need to get flushed.
I thought however that as part of the pw switchover the mac flush is instantiated.
either case you want to set up a stream of say 1000 pps so it is easy to verify and check the np counters to see where and why these paks are getting dropped and if it is the 9k or the me in that regard.
suspect a pw signaling and mac flushing issue here.

Hi,I've an iBook G4 bought in 2005, didn't even know it was going to be download redundant with the changeover, all I want to do is change from Safari to a Firefox compatible as browser..is that possible? I'm not techno, so go easy! Anna..

It was recommended that I try Firefox as it's more user friendly to accessing a variety of our sites of interest that aren't being facilitated by Safari. But your info says that the latest Firefox isn't compatible with my iBook..is there an older version that is, as, of course, I can't install any new software from intel onto this product ? I'm stuck with it as a browser & office work it seems, so I want to get the best out of that much!

Firefox 4 requires at least OS X 10.5 and an Intel Mac. There is a third party version of Firefox 4 that runs on OS X 10.4/10.5 and PPC Macs, for details see http://www.floodgap.com/software/tenfourfox
If you prefer, you can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html
