Cisco Application :: Cannot Telnet To ACE 4710 After Upgrade To A4(2.3)
Jun 29, 2012
I have a pair of ACE 4710s with 12 contexts sharing the load, running A4(2.1). esterday I upgraded one of them to A4(2.3) now I cannot telnet to the Admin context.Pings ok. I can telnet to other contexts on the box and everything seems to be working ok when i do a " sh telnet" comes back with
No Session Information is available
sh telnet maxsessions
telnet maxsessions 16
I have a pair of ACE 4710's that I am deploying within a datacenter. The primary and secondary ACE appliances have identical configurations except for the IP addressing and priorities for FT. The FT peer is going into a TL error state.
On the primary ACE appliance, I am able to ping and telnet from/to it without any issues. All of the routing works as it should and everything is seen in the ARP table as it should. The secondary appliance is able to ping everywhere, but telnet out of or into that appliance does not work.
I am able to see the IP addresses in the arp table and can successfully ping end to end from the secondary device, just unable to telnet into or out of it. When I try to telnet out of the secondary device, it reports that there is no route, even though the IP's I am trying to telnet to are directly connected and those interfaces are up and working (otherwise ping would fail). The exact same filters (access-lists, service-policies) are configured in the exact same format and applied to the exact same interfaces.
I tried removing all of the fault tolerance configurations and just created a Layer 3 vlan interface for management and I am still unable to telnet into or out of the appliance. This is not a complicated setup and I have to think there is something obvious that I'm missing, but I'm hung up on the fact that the config's are almost identical while one works exactly as intended and the other reports no route to host for a directly connected interface.
I am in the process of upgrading from v3.2.5 to v4.2.1, i have been follwing the upgrade/downgrade guide forv4(2.0) for my redunanant pair of ACE 4710.everything ok, following procedure after the standby is reloaded and comes up to standby-warm, Iget the license incompatabilty message on the primary.but I cannot telnet back into the standby, i can ping it ok though.I am loathe to go any further, and do the 'ft Switchover all' and reload the primary incase I cannot telnet back into the primary when it comes back up.
We are having issues with our Cisco ACE 4710, it suddenly stopped to telnet admin context.We are able to telnet another context from the same appliance, but unable to telnet the admin context. Is possible to pings the gateways from the other contexts, but we are not able to ping the gateway from the admin context.Actual we have 5 context with the minimum allocation is 10%.ACL and policy map allowing telnet and etc are enable and configured on the interface.
I am currently running A3(2.6) and evaluate the possibility of upgrading to A4(2.1). The Instal & Upgrade Guide A4(2.0) mentions that A4(2.0) does not include all features of A4(1.1). Does this apply to A4(2.1)? The Release Notes mentions a list of features merged from A4(1.1) to A4(2.1) but does not clarify if there any features not merged.
Upgrading a 4710. This is a brand new ACE out of the box and I have tried to upgrade a couple of times but get the same error... Here are the details:

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.
implementation of the cisco CSS 11501 boxes available as spare on our site into production for an application evry thing worked as expected. i was able to telnet the active/master box and was able to console both master and backup box from the console port.however a week post the activity im faced with this weird problem where im not able to take console or the telnet access of my primary/active box.The boxes are working in BOX-to-BOX redundancy and now im not able to telnet or console my active/master box. The telnet and console window prompts me for username and password and after entering the credentials nothing happens. no prompt or no error message is displayed.
The telnet primary authentication is via tacacs and secondary is via local. however for console im not using any method for primay authentication and local for secondary authentication. however i can successfully console my backup box. below are my obsrvations 1. the left and right status LED on the active CSS box is OFF.- it means my CSS 11501 failed and has no power. 2. upon firing the rcmd command with show line command on backup box i see that the telnet sessions and console session is established with the master box3. the redundancy state of the active box says it is master and has not changed state since my last activity, no application issue reported, all the services are active on the active box and also i can ping the active box ip address from my backup box over which box to box redundancy is established. This confirms the active box is functioning well 4. i initially thought the telnet sessions are not getting cleared, however the show line cmd with the rcmd cmd on the backup box confirms this is not happening. now im stuck as the active box cannot be accessed at all via console or telnet. i was thinking of below steps to be carried out.1. to failover the boxes and make the backup as master2. then try to take the faulty box off the network and troubleshoot (are there any other commands that i should use to troubleshoot)3. if nothing works try rebooting the box and check
NOTE: the software running is version 220.127.116.11 with standard feature set. we are not using cvdm or the CSS GUI. we could access the css initially on CSS gui and that is also not working now.
i'm looking for a recommendation for a setup guide including ft i've had a quick look a wiki and i can get basics but i'm not sure about if i need to setup additional contexts etc when i'm the only one using the appliance?
I have an issue with a customer that wants to update a server behind the ACE. The problem is that when the application wants to update the server it does it with the name.Doing some research I found that you can rewrite the record DNS based on the static NAT you set up on the ACE. The feature is called DNS inspection. Is the same feature as the ASA (DNS doctoring).I apply it to the outside interface and it did not work.
With the current (A5) ACE 4710 lic setup, does the "X gigabit per second appliance throughput" that is licensed affect: -
A) Only "appliance" i.e. load balancing traffic, any other normal routed traffic is not included in the limit
B) Is it an overall throughput limit on the interfaces i.e. includes all traffic not only load balancing traffic but also normal routed traffic crossing the appliance
Looking at a scenario where the lic size I need for HTTP load balanacing would be one size if A) but would need to be much larger is B) to accomodate out of hours routed backup traffic crossing the ACE 4710
I've got a web app that the owners want to run over port 80, but also using SSL to secure private data in transit. The architecture is an ACE 4710 in SSL termination mode->Apache (port 2000)->Back-End app server.
I've got two VIPs set up already - one on port 443 and one on 2000 - both of which do the SSL termination quite nicely, but using the 3rd VIP set up on port 80, the connection steadfastly refuses to be HTTPS (i.e. doesn't show the padlock).
I've done all the set-up through the web interface so far, can this be done? If so, how?
we configued An ACE 4710 with SSL termination on Oracle Aplication Server 10g (10.1.2.0.2) ,so that SSL termination is done on the ACE and HTTP reaches the Oracle Aplication Server 10g (10.1.2.0.2) then we configure the ACE to enabled client authentication with Pkcs#11 smart card token certificate and this don succfully my problem need do this client certificate authentication for only the [URL] not for all SSL proxy service how can do that.
We have recently transitioned one of our Ecommerce products to a new data center, at which we now use a one-armed load balancing approach rather then the routed load balancing approach we used previously. This is casuing us some issues as we generally log the source IP address a user comes in on when he fills out an application. Now the logs only show the natted ip address recieved by the load balancer, which does us no good. Any way to log the source IP address when a new connection is created to a particular vip?
If we use an ACE4710 to load balance two real servers, obviously it will use health checks to determine if a server is down.When it detects a server is down, it will not send it any more traffic.But can we also have it take any other action? For example maybe email an admin, or send an SNMP trap? Or better yet, can we use a custom TCL script to do other things, like launch some custom activities?
I am new to the 4710 appliance.Apart from the 4 GE 'data' ports, there are 2 Ethernet 'management' ("console") ports. I find the description in the "quick start guide"somewhat confusing. URL, Is a first-time serial connection (at least to run the initial config. script) mandatory? Or can you obtain the same result via one of the 2 Ethernet management ports and using a default ip address (192.168.1.10 ? When running the initial config. script (only possible from the serially connected console i suppose), you have to select your management port. Why does the system in step 5 proposes you 4 ports, and not just 2? I suppose the intended port for management is one of the 2 management ports, not one of the 4 data ports?
ACE# sh script code NORDICID_PROBE.Error: Called API is invalid or non-existant.Hardware is ACE-4710-K9 and software A3(2.7)The probe itself is functioning ok according to show probe detail.However show script script_name probe_name -counters all remain at zero for some reason. This wasn't the case on the previously use ACE software.To my recollection the command show script code has worked successfully before on the same ACE software. Not 100% sure though, but it definitely worked on the previous software we ran on the ACE.
We have two pairs of ACE 4710s, one pair running A3(2.4) and the other pair A3(2.0). We plan to upgarde the second pair so that they are running the same image as the first pair (we know they are not the latest, but this is the first step in a larger rollout plan, and to aid some troublshooting for a major issue we are seeing.)
I have details of the upgrade steps, but my question is with regards to the licenses which are now enforced after (2.0). We currently have the following on the first pair, but are these part of the default licenses for (2.4) or would we need to purchase these as well?
I need to use the Ace 4710 to distribute a Proxy PAC file, e.g. [URL] which will be configured in client browser using an AD group policy. Is it possible for the ACE to host and serve a file in this way?
Can the Nat Pool be on a different network that the load balanced vip? My current design uses nat pool on the same network, but the archatect wants the NATs on seperate VLAN.I will be developing on ACE MOD20, but the final configuration will be on 4710.
I configured ACE 4710 for HTTP traffic. All applications are running through real server. But when I run the same applications from virtual IP i.e through ACE. some applications are not running. Particularly applications having XML.
Is it ACE issue or Application issue. If it is ACE issue then how to troubleshot.
