recently when i run the commit vip redundancy script, i encountered the following error. This script has never failed in the past. Upon checking the backup CSS, i did notice that my most recent changes were actually synced. The following is the debug i have captured while running the script.

I have a application where I have to redirect a specific URL to another. The point is that the primary URL, have some information that I want to preserv after redirection, for example: url...
The default CSS11501 behavior is to redirect the primary URL to http://xyz.com. Just that.
I have CSS CSS11501 which is working fine in single arm deployment. Now I want to have redudency so that in case the switch 1 where CSS is currenlty connected is down.I can reach the CSS through the second switch 2.Both the switch are trunk with each other and CSS has one port connected with Switch 2.
We have several pairs of CSS11501 and 11503 in our network.This issue affects only one pair of CSS11503 in one of our data centres. [code] We use vrrp in one-armed mode for load balancing and they units have performed great for a number of years. We're obviously going to be migrating to ACE ... but not just yet.We have started to experience a problem with replicating the configurations between two CSS11503 in a pair.When running the commit-VipRedundConfig, it starts off happily enough, though slowly.Ending with "working" and the spinning cursor, even after 1 hour the script hasn't completed.We noted on the backup CSS that the APP configuration disappears during the process and I can't remember if this is normal behaviour.
Re-adding the app session configuration seems to interrupt the process, and when checking the configuration on the backup CSS approximately half of it is missing. Everything after the first owner is gone.
1. Configuration is too large, or just large enough to make the commit script take too long for realistic service. 2. Software bug? 3. Combination of both. 4. From now on manually add config to both CSS's and maintain it by process management.
I require to connect a "css11501" two core switches to provide redundancy to the load balancing service and would like to verify this possible (Does the spanning-tree protocol officer for load balancing?)
how to capture the incoming and outgoing packets on the balancer?The load balancer is connected in between the customer DCN and cisco switches 2960.The reason of capturing both incoming and outgoing packets on the balancer is to prove to our customer that there is no packet loss issue on the balancer, and it could be some issue on their DCN network.Since it is a production server, I will need to ensure that there is no impact to the incoming and outgoing traffic on the balancer and other networking equipments as well.
Is it possible to deploy the CSS11501 in one arm design to loadbalance the authentication traffic Radius across CSACS servers which is on UDP 1645 or 1812 port, is it required to configure the NAT or not, if yes how can define the shared secret in the CSS. also tell me how to configure the keepalive for udp traffic in this scenario other then default icmp keep alive

what is that mean-"Redundancy is not supported between an ACE module and an ACE appliance operating as peers" I'm designing network in which I plan to use ACE-4710-0.5F-K9 appliances.
Since the ACE supports only static routing, when pointing a default route from the ACE what is your preferred method when using multiple 6500s with an ACE in each in a failover scenario to prevent just pointing at one 6500? Static route to an HSRP address? Multiple static routes on the ACE, etc?
I'm using the Cisco ANM 5.2 version and I'm trying to import the configurations from ACE modules of Cisco switches. The first step is to import the configuration from Cisco switch and the second one is to import the ACE module in the ANM software. I'm getting an authentication problem to import the configuration from Cisco switch and of course I cannot import the ACE as well. The switches and the ACE are using AAA authentication and I have created a specific username to authenticate and import the configurations in the ANM. If I remove the AAA configurations from the switches and ACE modules it works fine.
Is there some problem with the AAA configurations in the switches or ACE module?
I have Ace 4710 version A4.1.1 and I am experiencing interesting problem with GUI and SSH reachability. I am unable to connect to management vlan3000. Interesting is that I can ping from ACE to network but unable to ping or SSH or HTTPS to ACE. Everything seems good. ARP is ok, switch is OK, line is up, protocol is up. Management is enabled for icmp, https, ssh to any.
When I do show interface I noticed line Config download failures : 9.

I have a ACE4710 setup to load balance a couple of web servers. The real servers all show as inservice as do the propbes and serverfarms/virtual servers. If I ping the Virtuual server ip address I get a reply but it I try to access VIP via telnet or web browser. I get a connection could not be open error on the client.The question is how do i determine where the error is comming from so far I can not tell if the client is getting through the acl or not.I have used the trouble shooting guide and nothing has worked to determine the cause so far. show service-policy int479 detail does not show an increase in the hit count when I try to connect.show stats conn does not show an increase in failed or timed out connections when i try to connect.

We're using a CSS501 to load balance http requests over three servers running windows server 2003 and IIS 6. On Saturday I attempted to switch over to three new servers running the app on Server 2008 and IIS 7.5, I mirrored the used the existing setup to create the new environment (pwgecashwww01,02,03 Owner ACMENewServers and group NewServer).
Everytime I make a config change to one of the contexts on our ACE20, I get this message: Config Application in Progress. This command is queued to the system

I have a customer who is looking to add some redundancy to their internet connections. Currently we have an ASA 5510 for their firewall. I know that the Sonicwalls are capable of terminating multiple internet connections simultaneously for load balancing, redundancy, and for pushing different types of traffic out different connections. Traditionally the ASAs have not had that capability. But does anyone know if the newer revs (8.3 and I think 8.4 may be out?) will do that or anything similar? Not looking for a full BGP-style solution where the same address space is available via multiple links, but more just a solution where the internet for basic web browsing could fail over and load balance between two internet connections, each assigned to a different outside interface on the ASA.
I'm shortly going to move our stuff to a new data centre, where we have two network feeds - so there'll be two lengths of CAT 5 coming into the rack, for "first hop redundancy".I have something similar at our existing DC, but I'm simplifying the equation somewhat at the new DC, and using a simpler configuration that just uses two switches, rather than two switches and two routers. All of the servers will have public IP addresses.Now - the network guy at the new DC has confirmed that a simpler two switch configuration will work.
We have cisco 1841 router with two ISP . But we facing the problem whenever our secondary ISP Link goes down the Primary has also went down.We have only one default route for primary Link
I have a question with regards to 6500 Redundancy. We currently have only one in our DC, it has 2 SUP 720s, two FWSMS, and multiple switchport blades. My question is is this fully redundant? and if not what is it that can fail, so I can look into adding that extra layer of redundancy.
I have a 4510R+E switch that won't change to the SSO redundancy mode. After entering the 'mode SSO' command, the switch reboots the peer supervisor (as it says it will), but after it comes back up it remains in RPR mode. I've tried rebooting the peer supervisor manually, rebooting the entire chassis, manually power cycling the entire chassis, and reseating the sups, but the switch remains in RPR mode. The issue started when I swapped the switch's supervisor with the supervisor of another 4500. The same issue was observed on the other 4500 as well, but after several reboots, I got it to change to SSO mode. Prior to the swap, both switches were running in SSO mode just fine.Since we're running IOS version 15.0 with the 'spare sup' license, I suspect the issue arose because of licensing complications (with relation to the chassis serial number and the like) when I swapped the sups....although this doesn't explain why the other switch changed to SSO after some troubleshooting.
I have problems with the RV042 router. Currently I have two Internet service is the first DSL service and the other is through cable. The problem is because the router is not doing the redundancy process. For example if DSL service fails, the cable internet service does not come automatically. You have to disconnect and connect manually to maintain the connection to the Internet. Should not the router do this automatically without intervention?

I would like to add a redundant supervisor blade to the 6509 that is in production. Can this be done plug and play and require no reload. Are all WS-SUP720-3B the same as far as memory etc... or can I buy any used WS-SUP720-3B and it will work properly.
Can the above be used to provide redundancy. However there is only one ISP side connected? Of course we can set up both with exact same rules and use a Manual power on/off if?
First and foremost, what I have are 2 x 7204VXR (Gateways), 1 x 4507R-E (Coreswitch), and our ISP have 7609.Got some issues with redundancy with our ISP.
7609 I I I I 7204-A 7204-B | | | vrrp | | | -4507R-E- | | internal network
Both outside interfaces of 7204 gateways are connecting to 7609 with different public ip block. I used VRRP for my internal nework and failover have been tested working.
Even tried to remove link of 7204-A and 7609, the failover works perfect. If I shutdown/ remove the link between my 4507R-E and 7204-A (primary gw_higher vrrp priority), vrrp redundancy/failover still works, but pings from internal network to internet is only 50% success....alternate 4 ping reply and 4 time out.
i have a 6509 connected via layer 2 (VLAN1) to a 3750 (e.g. VLAN1 10.1.1.1)then to the HQ via Metroethernet(L3). Is it possible to connect the 6509 to an ASA that already has VPN connectivity to the HQ using HSRP? Also need to mention, the VPN connection is supposed to be the redundant connection if Metroethernet link fails.
We will be getting a circuit from the same ISP at two of our sites and will be doing eBGP. Couple of notes. 1. We are fully aware of the risks associated with depending on a single ISP and have mitigated them as much as possible with the ISP. 2. We will be getting assistance on the eBGP setup from the ISP, so I’m not as concerned with that config at this point.
Site Summary
Site A:Cisco 2900 Series (RtrA) connected to single Ethernet based ISP circuit (ISP-1-A)eBGP will run between RtrA and ISP-1-A, default routes from provider onlyLayer 2 Switch (SwA) connected to LAN of RtrA and uplinks to SwB
Site B:Cisco 2900 Series (RtrB) connected to single Ethernet based ISP circuit (ISP-1-B)eBGP will run between RtrB and ISP-1-B, default routes from provider onlyLayer 2 Switch (SwB) connected to LAN of RtrB and uplinks to SwA
I need advise on the LAN side redundancy. Our goal is redundancy; load balancing is not a concern (If load balancing ever becomes a concern I will look at GLBP). We have several devices on the LAN side of the routers that can only use a single gateway. Given that I’ve surmised I need to use HSRP in some way for LAN gateway redundancy.
1. HSRP with Object Tracking, No IGP.HSRP handles LAN gateway failover if a router dies. Object tracking ensures LAN gateway failover if an interface fails or if an interface is up, but there is an upstream traffic issue. ie. track the physical WAN interface and use an IP SLA icmp to track a specific upstream IP incase of an upstream traffic issue.
2. HSRP with OSPFHSRP handles LAN gateway failover if a router dies. OSPF redistributes eBGP default routes to RtrA and RtrB so that each router should have a route to the ISP even if they loose their local ISP circuit. i.e if ISP-1-A on Router A goes down, Router A knows to send traffic out ISP-1-B via RtrB. In other words, traffic enters RtrA LAN, but exits on RtrB WAN.
3. HSRP with iBGP HSRP handles LAN gateway failover if a router dies. I have no experience with BGP, but assuming this would work similar to the OSPF solution above except for the required iBGP config and possible route reflectors?
I'm new to firewall using ASA 5510. How can I have a redundancy over two ASA 5510. Hardware load balancing and IP Load balancing, just like HSRP or GLBP. Below is my diagram.
Two internet links from different SP using different routers an firewalls connected to a 6513. I need to use these two links as primary and secondary (the secondary will be used just if the primary fails) for just two specific machines and 6513 have to be responsible for jusing between primary and secondary link. The rest of the network have to use just the primary link.
[URL]I ran across this on the cisco site and I wondering if it was possiable with two 2851's? The part that is most interesting to me is this part of the config (this looks like what allows the use of the y-cable)
actually im using a cisco asa 5520 as a default gateway to acessin/ publishing in the wan. i have a cisco 2811 configured to replace the cisco asa in a case of problem, but the switch is made manually. my lan switch is a 2 3560e configured with hsrp, so it is possible to make redendancy( failover) between the cisco ASA 5520 and the cisco 2811 using a hsrp or other technic.
