ACE 4710 deployment model. We'll be doing an eval later in the year, but I'm just looking to understand the architecture.We have a stack of 3750 switches with a single VLAN (10.1.1.0/24). Connected to that stack is a pair of web servers (10.1.1.5 and 6) that we want to provide load balancing/failover for. Some of the clients are located right there on that same VLAN. Other clients may be coming from other spots in the infrastructure.It sounds like I could put a pair of 4710s connected to that stack of switches, in a single arm deployment? And then the virtual IP and the real servers would all be 10.1.1.0/24. Maybe use an etherchanel to connect each 4710 to two 3750s?
I have a problem, recently I can not telnet to the ACE 4710, the ACE version is A4(2.0). I can enter by web and console but not for telnet. I try to give more resource to the admin context but it doesnt work.
We have a rather strange issue, and I'm not sure it's really a problem with the ACE or not. We created an HTTP parameter map called "TCPreuse" and applied it to a virtual server. A show conn detail displays "[ conn in reuse pool : FALSE]" for all connections pertaining to this virtual server. The rserver in question is Linux(Ubuntu) + Apache.Next we applied the HTTP parameter map to another virtual server - this time IIS7 + Windows Server 2008. There are plenty of entries "[ conn in reuse pool : TRUE ]" when I do a "show conn detail".What could the web servers be doing differently that would cause the connection reuse to work on one virtual server and not the other?
I need to upgrade 2 active-standby cisco ACE4710, the issue is I cannot access FTP/TFTP/SFTP server via Admin context but can be accessible via other contexts.
Can I copy the ACE system software file from FTP/SFTP/TFTP server to image: directory durectly or need some other way around ? I could see the option is available to copy ftp: to image: via other context.
My customer they do not want change their real server IPs. So I need setup one interace (one armed) for them on ACE4710. Who had this sample configuration? (CSS has this but it seems to be not compitable with ACE)
I am attempting to configure an ACE4710 to perform SSL end-to-end confguration. i.e. SSL termination - load balance - SSL initiate to backend server.The configuration appears to work fine in a test lab using any old web server, however when I peform the same configuration in the production environment it does not work. It appeatrs from a capture run on the ace that the ace is reseting the tcp connections after communicating with the back end server. The main difference I can think of in this environment is that the cert and key pair the ace is using where exported from the backend server, i.e. both the ace and the backend server have the same certificates and keys. Is this allowed? how to troubleshoot why the ace resets the connection.
All clients point to unique VIP and Port configured, I need to know if I can apply any filter or rule that allows me to distinguish when a customer goes to the URL1 or URL2.If any client try to access to URL-2, your traffic must be deny.In summary, from Internet I should be able to go only to URL-1.
I have to deploy the Cisco GSS in our 2 dataceters globally seprate IP ranges to loadbalance the exchange 2010 environment with Cisco ACE 4710 series SLBs. The scenario is to deploy one GSS + ACE on each datacenters and our nameserver will point to both GSS's IP addresses to get through. Incase primary site "site A" goes down name server will point the client's request to "site B".
What will be the physical setup of the GSS here and what configuration should on SLB ACE will make it work? Do GSS and ACE need to be in the same vlan? is this necessary to use Both interface of the GSS to get things working? How the GSS will check the health check on ACE if they both are on different vlans/ip range? Our ACE will be in routed mode do we need to assign the Real server default gateway as ACE inside interface with the server farm or just do the SNAT of the client IPs so the request can come back to ACE?
I have HA configuration for two ACE4710. FT between Ace's is configured as L2 (V LAN). Active ACE is sending heartbeats, but switch shows lot of 'input errors' on ingress and this is a major problem. FT is logically not working (there is no connection between these two Ace's over V LAN). There is only L2 configuration, with speed and duplex auto, no other special configuration. When I connect Ace's directly, FT is working without problem.
I can see lot of errors on input direction (from ACE) to switch port, that means, L1, or L2 problem, but direct connection (using the same Ethernet cable) is working. I tried 'shut/no shut' on both sides, set duplex/speed,... without success.
Do you know if it is possible in ACE 4710 appliance to configure a SIP TLS ?The SIP probe we have in the configuration guide it is only for clear text. for Lync 2013 we need to establish first a TLS session and then within it, send an SIP request..IS it possible in any version? I tried also to configure a HTTPS probe but it fails as it sends a GET which the Lync SIP server doesn't understand.
I'm implementing and found out some issues are unresolvable on ACE4710. This network have been running on a server without LB. Now the second server comes up. We choosed to implement with Routed Mode.This network Peak @ 300Mbps. Now on we're doing the first context which is function as content web-farm. In near future, 2nd context which takes care of indexing web-farm when they buy more server.
From following diagrams.I browsed from internet into this service. "show service-policy" shown as '0' (counter was not running). I guessed that there is something wrong in FW configuration. So I isolated out FW. Then I plugged-in my PC into network 30 (192.168.30.X) in front of this LB, then browsed into LB's VIP (192.168.30.1). LB "show service-policy" came up BUT there is nothing return to my PC (client). "show conn" on LB as "SYNSEEN". What's SYNSEEN?! Some meaningful.
Then I tried to figure out with a PC running 'apache' and took the place of real server. "It works!" returned from LB/Server. "show conn" became 'Establish' Programmer guy said if I browse into web-farm (i.e. content web-farm) directly pkt will be redirected to indexing server. But they said it will be L7 redirection. Not LB/Network level.
We recently configured a setup to loadbalance 2 application server using ACE4710. Initially the configuration was to link two app servers directly to ACE4710 without connecting to a Switch, but later, it was advised that ACE4710 is not able to work without connecting to a switch.
1. ACE4710 is not able to link directly to APP/WEB server, but it must go through a network Switch.
2. If item-1 above is true. We used to have a older Cisco Loadbalancer which is able to link directly to WEB/APP servers. What is the reason or advantage of removing this feature?
On my ACE4710s I'm using least-loaded predictors monitoring Microsoft Windows CPU usage. There are times when the MS Windows CPU OIDs can change between reboots. Any way for the ACE to automatically adjust to the new CPU OIDs and continue to get accurate CPU usage values?
one of our 2 ACE boxes in FT group suddenly reboot-ed from active state and now it continuously reboots with the following error:
insmod: error inserting '/isan/bin/klm_octeon_device.klm': -1 No such deviceerror inserting /isan/bin/klm_octeon_device.klmDaughter Card Not Found. Rebooting..INIT: Sending all processes the TERM signal...
We have a CSS11503 that is currently being used to accept incoming HTTPS and SSH connections on a specific VIP and then PAT those client connections. I understand that it also PATs the server initiated connections. [code]
For server load balancing, does the ACE4710 support custom protocols? We'll be using HTTP for server health monitoring, and to determine if a server is up or down. But the client/server application is custom, and includes a lot of non-standard ports. Can the server VIP handle generic TCP connections? For example client1 connects to the VIP on http, but then later client1 switches to using tcp842 (a custom protocol, not http).
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. [code]
My customer wants each ACE4710 (of a highly available cluster) to have its own, dedicated port for management purposes.
According to documentation, IP addressing can be applied to VLAN interfaces, so in order to satisfy the requirement, I should make one port belong to an "access VLAN X", and then apply IP addressing to the corresponding "interface VLAN X". This should satisfy my customer´s requirement in an indirect way.
But... ¿ Can´t I just configure IP address on one of the 4 ethernet ports in order to save the work of building the aforementioned VLAN? I am asking this since I do not have access to a real box in order to verify.
Current topology in network is such: web servers with content needing to be load balanced are in vlan 35 and these servers are directly connected to Core switch (two 6509 VSS) via 20 Gb EtherChannel. Vlan 35 also spans some other switches with other servers residing in this vlan. Additionally, there are dozens of another vlans (including external users) that need to communicate with web servers. IP addresses of these two web servers are: 192.168.35.1/24 and 192.168.35.2/24 accordingly with default gateway 192.168.35.254/24 (SVI on Core switch). Currently these ip addresses are used by management and other purposes and need to be reachable for same purposes after configuring load balancing with ACEs - it is needed to have direct access to servers behind ACE. How I can do that using ACE in routed mode?
Physically, it's like this. The RED line denotes a boundary, and pretty much anything North of that is not accessible to us, we simply have a L3 trunk between our switches and "their" switches (S3/S4) and talk using EIGRP.
There are other servers in the top tier, some that also require load balancing, some that don’t. Typically, I want to load balance HTTPS requests from the internet, to one of the 3 servers in the top half.
I’m not sure what mode to select, routed, one arm? What about placement of the ACE? At the moment, I’ve just configured 1/1 on it and made it part of the MG MT VLAN, it's S VI exists on the S1/S2 switches, so I’m open to change as it's still all in the lab.
I was trying to implement stickiness based on cookie. Server inserts a cookie and sends it to the browser. I learned from app team that this cookie is changing dynamically during the session, so stickiness based on server’s cookie doesn’t work.
Now I want to investigate into possibility of ACE to insert a cookie. My question is: ACE feature of “cookie insert”: does it add additional cookie into http header without removing server cookies or it deletes the cookie(s) that server put into http header and replaces them with its own cookie?
We have an ACE Appliance in a DMZ and the ACE Appliance's Admin Context IP is translated between ACE and ANM. The ANM Server does not get translated. It is just the opposite then in another Community discussion.
Our Problem: When adding the ACE4710 Appliance to the ANM imported Device List, we use the ACE's NATed Admin Context IP. Import works well, but ANM reflects the Admin Context IP with it's real configured IP. Polling the ACE Appliance does not work therefore.
Is there a possibility of telling the ANM, that the ACE has to be polled through a NATed IP? I could not find a field to set a NATed Mgmt IP.
Configured IP on ACE Admin Context: 192.168.0.10 NATed ACE Admin Context IP: 172.16.0.10
Imported ACE with IP 172.16.0.10 into ANM, but ANM polls for Rserver, Vserver, Probes, etc. via 192.168.0.10 - which is not reachable from the ANM.
When two Routers Models 1941 (Main Router) and 1841 work connected with HSRP, and a second LAN card is added to each one of them If i connect the GE 0/1 and Fe 0/1 of each of one of them To FireWall1 (in cluster with FireWall2) AND i connect the second LAN (Added) of each one To FireWall2 (in cluster with FireWall1) If FireWall1 will failure , How can Router 1941 know, to move traffic from GE 0/1 to the second LAN card connected to FireWall2 (which is in charge now, by cluster definition)
We are considering order the AP541N for our network. A few questions...
1). Are there multiple models of the AP541N? or just one cisco part number?
2). I am assuming the basic antenna comes with it. If this is something that I need to buy seperate.
3). Are there part numbers for the POE injector? Need to know part numbers on the AP541N and the poe injectors?
4). We would buy a couple of these and run them in cluster mode. My understanding is that I won't need a controller. Do I need to buy a certain model to use the clustering or is that available on all the AP541N?
5). Can I have this talk to active directory to authenticate users? Is that tough to do? Do I need install some kind of agent on a domain controller? I have configured the ASA to use Active Directory for authentications. Should it be any more difficult that that?
I have setup a few other Cisco APs before and am generally familair with wireless. But, I am not a "wireless expert" and don't have any experience with this particular product.
We are looking at doing some switch replacement. These switches will be in for ~7 years.We need POE for a VOIP phone system, and 10gb uplinks back to the core. We want to have the ability to go POE+ in the future.
We were quoted from our vendor for:WS-C3850-48P-S with 2x715w Power supplies. It looks like the data sheet says that to get POE+ you need 2x1100w or 1x1100w & 1x715w. Do we need to step up to the WS-C3850-48PF-S?
(eth ports routing only) and a layer 2 switch into a cluster of two layer 3 switch clustered. I have looked at Cisco 3550 EMIs with HSRP but I would like to implement based on newer models of Cisco switches.
We have acquired few AIR-BR1410A-A-K9 AP's that are for US only. I am in Pakistan. For our market, Cisco proposed AIR-BR1410A-E-K9. This is fine as it is listed on their website as well.However, since we also have the "A" model and now the "E" model, can we place an A model on one end and an E model on the other and make them communicate with each other?
I am planning to build a site to site vpn tunnel, connecting 2-3 satellite office to the main office.After searching the product, I really don't understand the difference between models like the ASA5505 and RV042.Can I need to use ASA5505 in the main office while RV042 in the stallite offices? Or can I use RV042 (or upper) in all the office and it is enough for vpn tunnel?If it is the case, what is the benefit of ASA series over the RV series?
are there any AP models which support 5500 series and dont support 4400 series. Actually we are looking to get some new AP with higher bandwidth and External Antenna How to differentiate between AP models with clean air feature supported and not
I have one AP541N and need to extend the wireless network with a second wireless AP. Which models of AP can I use with the AP541N to achieve a 'cluster', please? Is it just with a second AP541N or can I use other Cisco APs to achieve the cluster?
Am I correct in thinking that doing this will allow wireless clients to 'roam' seamlessly between the two APs?
