I've been having some issues with my BT Broadband for a while, so decided to switch to a new router, a TP TD-W8960N, however setting up QOS isn't as easy as I had anticipated (I'm fairly new to this!).
My main issue is that we have a fairly limited broadband connection, but I need to backup work using backblaze. This is a pain because as soon as it starts to backup it eats what bandwidth we have. What I want to know is can I just limit the range of ip-addresses which they use for their backup?Is there a simpler auto-QOS approach I could use? The router is currently running the latest firmware that isn't in beta. Also - do these routers auto-update firmware?
I periodically have my ISP's DNS go out. I actually prefer to use the default DNS they provide (and not hard-code it), but still, it occasionally goes-out for an hour from time-to-time.Is there a way on the DIR-825 to add a "backup" DNS (3rd DNS), that is fed to the PeeCees via DHCP, in addition to the 2 my ISP provides?
View 3 Replies View RelatedBasically we are having a Multicast setup. both A and B offices are being connected with STM-4 (622 Mbps) with IGP as OSPF. As of now everything is working well with this setup and no complaint .
Now since Primary link bandwidth is touching upto 622 Mbps we are planning to send some traffic to backup STM-4 link .
1) To send some unimportant (Traffic) Source IPs ( say 10.20.1.1 to 25 ) to backup link what would be best way to achieve it. Is it possible policy based routing ? does multicast support pbr?
2) When primary STM gets down and entire traffic shift to backup STM these IPs ( 10.20.1.1 to 25) should be given low priority on the backup link or traffic from these ips can be terminated.
We have 6 sites which are connected through E1 links.All sites connected from HQs.
Site A is HQs.
Sited B, C, D, E, and F are Branches.
Site A is directly connected with site B, C, D and E.
Site D is connected with Site F.
Now we have another redundant E1 link for site C and Site F.we are using Static Routes.i have configured Qualified-next-hope on Juniper Router but i am unable to configure IP SLA on Site C Cisco 2951 with IOS 15.0 router.is there another solution for my scenario plz share with me for Redundant Link.
I'm working on setting up a backup link for our ASA 5505 and I've followed these directions: [URL]
The backup ISP gives us a dynamic address, however, when I enable the backup ISP's interface on the ASA, my vpn tunnels drop. As soon as I disable the backup interface, the tunnels come back up. I'm attempting to configure this across one of these tunnels, so obviously this is an issue, as is the fact that other people need the tunnels as well. I'm not sure what I did to make this happen, but I've been over the config many times and can't see anything different from the instructions in the link above.
I thought it might be trying to route traffic across the backup interface, but my primary interface is tracked and has SLA running on it, so I would assume it wouldn't roll over onto the backup interface.

View 2 Replies View Relatedi have two internet links each of which from different ISP and different real ip addresses.Want to make the second backup internet work for Internal and external (AnyConnect) users.
my question: is that applicable to register single A record with different real ip addresses? and also is the AnyConnect method the best solution for them?
note: i have single firewall 5520 behind the cable modems.
My requirment is to drop the Internet traffic once the Cisco HWIC 3G backup link will become active(attached) .Because I should allow only Business Critical Data allow through that and others should drop. Here are the config I used. In here I used a standard access list to generate intersting traffic which allow all the traffic traverse through the backup link.Can I drop the packets to the proxy (192.168.1.100) using this access list and allow other traffic.access-list 1 deny 192.168.1.100access-list 1 permit anydialer-list 1 protocol ip list 1.Is this the proper way I should follow ? Is there any other good method to achieve my requirement ? [code]

We have 2 dsl lines coming in and the modem is in bridge mode while the router handles the pppoe information. Each line is 6mb down and .5 mb up. It's ****, yes I know, but this is pretty decent for a small town in the country. To double our bandwidth, I put it in load balance mode. When load balance, I get anywhere from 9-12 down and .8 up. Here's where it gets tricky.
When anything is uploaded, the speed drops from 9-12 down and .8 up to about .2-.7 down and .2 up. I realize that we will lose some down and up speed but I wouldn't think it would be this drastic. Is this normal?When they upload to a specific https site (file is about 50mb), it never initiates the upload. If I switch it to Link Backup, it will upload fine. I still lose the speed but at least it does something. I've read that some https sites have issues with grabbing data from multiple IP's so I figured this is the case since it's a medical site that was probably developed in house. Is this true?Does protocol binding work in Load Balance mode? I binded all http and https traffic through WAN 2 interface however, when I do a speed test or check my external IP, it is not indicating the WAN 2 IP address. Is this a common issue in rv042's or is there a firmware update that solves all these issues?

View 1 Replies View RelatedCurrently we have 20 remote sites, each with 2-5 AP's each. They all connect back to our Main Data Site in the US and register on a single WLC5508.
We do not have a backup WLC, but are looking to purchase one. What I would like to know is, are there any problems with the secondary WLC being installed in our Main Data Site in Europe? These two main sites are connected via a 10M MPLS WAN.
So all the remote sites could still connect to the WLC in the US, but in the event of a WLC failure in the US, they would need to fail over to the site in Europe

View 2 Replies View RelatedHere's the list of equipments:
Pool of oeap 600 aps
1x 2504WLC as OEAP WLC (@DMZ)
1x ASA 5515
Scenario:
My OEAP WLC located at ASA - DMZ is NATted to a public ip (primary internet ISP), then my pool of OEAP-600 were configured to communicate with this OEAP WLC.
My question is:
I want to automate the failover of OEAP-600 (I don't know if this is possible) to the secondary internet ISP whenever the primary internet ISP fails. The secondary ISP is terminated on the same ASA 5515-X doing PBR and IP SLA stuff.
I know that OEAP 600 can only be pointed to one WLC ip address I know that the WLC can only be NATted to one public IP address.
What would be the best solution to perform the OEAP backup connectivity? Or just buy another set of WLC/ASA then just manually configure the OEAP-600 APs to point to the secondary ISP.
My customer has a 4402-25-K9 and need a backup (failover) controller to avoid data transmision break when primary controller goes down.4402 are end of sale so I have a question can I use 5508 to get Controller Failover Protection with 4402 ?

How do I tell it how far back I want to keep logs, or how many log files to keep before deleting the older ones? Seems like it will just keep on saving the config backups with a date stamp until the TFTP server runs out of disk space.

I have a facility, where all the access points almost 250 of them are connected to two WisM's (One in each core switch ) . They are running in 6.0.199 firmware . These two WisM's are managed by WCS , which is running 6.0.188.
As i need to add more access points and to make fully redundant , 5500 controller was ordered and it has with firmware 7.0 installed. Couple of queries related with it .
1. Can 5500 be added in the WLC group, so that existing Access Points can be configured to use primary controller as 5500 and secondary / tertiary controller as WISM ?
2. Will 5500 be able to be detected by WCS , as the version of 5500 is 7.0 and WCS version is 6.0.188 ?
3. As WCS was already deployed and live, is it possible to upgrade, if the client has support contract like SUSA ?

Since WLC5508 MGMT interface is configured a AP-Mgr at the same time, can I set a Backup Port to WLC5508 MGMT interface? Refer to WLC configuration Guide:
In the Backup Port text box, enter the number of the backup port assigned to the management interface. If the primary port for the management interface fails, the interface automatically moves to the backup port.
Note Do not define a backup port for an AP-manager interface. Port redundancy is not supported for AP-manager interfaces. If the AP-manager interface fails, all of the access points connected to the controller through that interface are evenly distributed among the other configured AP-manager interfaces
if I need to configure the backup port for MGMT interface, i need to remove the AP-manager on MGMT interface and create a network dynamic interface for AP-Manager ?

View 1 Replies View RelatedI have a E1550 with a corrupt config that is acting very wonky lately (shows wrong info in some of the settings and doesn't always save changes). Since it may be the config that is at issue, I don't want to do a backup/resote, rather I plan to do a full factory reset and manully type everything back in.What would be nice is, creating a text based, human readable printout of the config for reference so that I don't have to manually type it all twice (once to save it, once for reentry). PS3 ports, MAC filters, etc. have several entries, and they way the pages are designed it doesn't allow for easy, whole entry, cut and paste.
View 5 Replies View Related I have a 1.5 TB USB hard drive attached to me E4200. Configuring it so that multiple computers have access and can read and write their files is quite simple. I've followed the instructions and had no difficulty.
My problem is this, after about a week's time has passed any file that has been on the hard drive for more than a week become undeletable. Any attempt to modify it or remove it pops up a message saying I need permission from a specific user (always the user that I am currently logged in as!) to perform the operation on the file.
When this starts to happen, the device is, otherwise, perfectly functional. I will still be able to create new files and delete any newly created files from the drive without difficulty even when those files are in the same directory as the files that the device will no longer let me edit. Examination of the file properties dialog shows that the files that the device refuses to allow me to delete are identical in every way to any new file that I create. Yet newly created files are removable but these older files ... are not.
I'm quickly coming to the conclusion that the HDD mounting feature of the device just doesn't actually work as advertised.
FWIW: all my computers are using Windows 7 with the latest build. I do access the device from these computers wirelessly.
why Windows Backup in Windows 7 pro 64 would not backup over the network to a drive I have connected to the 4200s USB port? Everytime I run it I get a Access Denied error at the end, even though data has been transfered. After about 5 hours of searching both here and Microsoft's website, I just get lots of people with the same issue that hasnt been resolved anywhere consistantly.

Why does Cisco recommend a configuration of originate-only on the ASA with multiple peers configured and the answer-only to the other end? Shouldn't it work as Bi-Directional ?

The only scenario I see which could break is if both peers try to establish a VPN at the same time to the ASA. Is there any other reason ?
