ACE 4710 Setup

Dear All,
I have task to add two servers to work with ACE 4710 , the client is coming from internal network and the end host (our servers).
I don,t know how to connect it physically and do the configuration.
Thanks a lot in advance .

Hi,
Below is basic configuration example with three real servers and Source NAT.
Let's say you have three servers:
rserver host SERVER_01
ip address 192.168.1.11
inservice
rserver host SERVER_02
ip address 192.168.1.12
inservice
rserver host SERVER_03
ip address 192.168.1.13
inservice
You add them in serverfarm
serverfarm host REAL_SERVERS
rserver SERVER_01
    inservice
rserver SERVER_02
    inservice
rserver SERVER_03
    inservice
After that you configure the VIP and condition. Here any means any protocol and port
class-map match-all VIP-30
2 match virtual-address 172.16.51.30 any
YOu define the L7 policy map
policy-map type loadbalance first-match SLB_LOGIC
class class-default
    serverfarm REAL_SERVERS--------->Serverfarm to which traffic would be loadbalanced.
policy-map multi-match CLIENT_VIPS---->L3 policy map.
class VIP-30
    loadbalance vip inservice
    loadbalance policy SLB_LOGIC
    nat dynamic 1 vlan 451----------------->You need to apply the NAT when your client is in same subnet as server so that return traffic comes back to ACE and not to client directly or when your servers default GW is not ACE.
interface vlan 251
description Client vlan------------------->VIP is in this subnet
ip address 172.16.51.11 255.255.255.0
access-group input ANYONE
service-policy input REMOTE_MGT
service-policy input CLIENT_VIPS
no shutdown
interface vlan 451--------------->Server side subnet
description Servers vlan
ip address 192.168.1.1 255.255.255.0
nat-pool 1 192.168.1.100 192.168.1.110 netmask 255.255.255.0 pat---->Nat pool defined. It should always be on server side vlan.
no shutdown
ip route 0.0.0.0 0.0.0.0 172.16.51.1
I would also suggest going through the below for basic troubleshooting and understanding.

FT VLAN / Trunk or L3 Interface? ACE 4710 setup

Hello, Is it possible to use 1 or 2 of the 4 gigabit ethernet ports from one ACE straight into the other ACE for redundancy?
So ACE_01 gig0/4 to ACE_02 gig0/4
If so, is it a case of just having the layer 3 config instead of trunking etc..
Also - is it possible to create a context within the same vlan as the Admin context?
Thank you
Please rate useful posts and remember to mark any solved questions as answered. Thank you.

Hello Kanwal, thank you for this. This is my first pair of ACE's configuring from scratch.
I've dedicated int gi1/4 for the ft 'transit' traffic if you like - its dedicated on a separate vlan. So both ACE's are connected directly on this port.
I have two VLANs - 724 & 725
And 3 contexts. Admin, NPE, DEV
The Admin Context lives in VLAN 724 I created another context (NPE) in the same VLAN. Do I have to use a different address for the interface in this context or can I use the same as the Admin context?
SQP-ACE4710-NPE01/FOS_NPE# conf t
Enter configuration commands, one per line. End with CNTL/Z.

ACE 4710 blocking FTP WLSD directory listing

Hello
I have a ACE 4710 setup in a test environment(and context) with 2 filezilla FTP servers on the back end and a Win7 laptop on the front end with a FTP client(s). The ACE is setup to load balance by source(the requirement for our project).
When the laptop tries to FTP to the Filezilla FTP servers it connects, enters passive mode, and sends a WLSD command to get a directory listing, but never gets it. If the Win7 laptop is put on the same vlan as the Filezilla FTP servers, behind the ACE, everything works fine.
As far as I can tell the ACE configs doesn’t have any sort of deny acl acting on this traffic. *attached* The FTP client always connects, its just the directory listing that doesn't seem to work.. and we need it to work for the app this is targeting.
Any help is greatly appreciated.
e-

Yeah me too!
So after much packet capturing and hair pulling and general dismay, we(me, another admin, and a local var ccie) think this is a app layer issue. We added the inspect command but it wouldnt take without a nat pool in place, so we added that.
We found a packet in the FTP client that tells the server the real IP of client to the server. This is the only oddity that we can locate. Of course I admit we arent using a ACE in the normal way an ACE would be used, we LB by source not destination.
I put telnet servers on my targets and they also communicate directly to the clients IP, but they layer 2 back to the ace first, whereas the FTP server doesnt. We are still working on it to try and find a way to make FTP happy.

Need help to Configure Cisco ACE 4710 Cluster Deployment

Dear Experts,
I'm newbie for Cisco ACE 4710, and still I'm in learning stage. Meanwhile I got chance at my work place to deploy a Cisco ACE 4710 cluster which should load balance the traffic between two Application Servers based on HTTP and HTTPS traffic. So I was looking for good deployment guide in Cisco SBA knowledge base then finall found this guide.
http://www.cisco.com/en/US/docs/solutions/SBA/February2013/Cisco_SBA_DC_AdvancedServer-LoadBalancingDeploymentGuide-Feb2013.pdf
This guide totally fine with my required deployment model. I have same deployment environment as this guide contains with ACE cluster that connects to two Cisco 3750X (Stack) switches. But I have some confusion places in this guide
This guide follow the "One-armed mode" as a deployment method. But when I go through it further I have noticed that they have configured server VLAN as a 10.4.49.0/24 (all servers reside in it) and Client side VIP also in same VLAN which is 10.4.49.100/24 (even NAT pool also).
My confusion is, as I have learned about Cisco ACE 4710 one-armed mode deployment method, it should has two VLAN segments, one for Client side which client request come and hit the VIP and then second one for Server side. which means besically two VLANs. So please be kind enough to go through above document then tell me where is wrong, what shoud I need to do for the best. Please this is an urgent, so need your help quickly.
Thanks....!

Dear Kanwal,
I need quick help for you. Following are the Application LB requirements which I received from my clinet side.
Following detail required for configuring Oracle EBS Apps tier on HA:
LBR IP and Name required to configure EBS APPS Tier (i.e, ap1ebs & ap2ebs nodes)
Suggested IP and Name for LBR:
IP : 172.25.45.x [should be on same 172.25.45 subnet of ap1ebs & ap2ebs nodes]
ebiz.xxxx.lk [on port 80 for http protocol accessibility]
This LBR IP & name must be resolve and respond on DNS network
Server Farm detail for LBR Setup
Following detail will be use for configuring the LBR:
LBR IP and Name :
IP : 172.25.45.x [should be on same 172.25.45 subnet of ap1ebs & ap2ebs nodes]
ebiz.xxxx.lk [on port 80 for http protocol accessibility]
This LBR IP & name must be resolve and respond on DNS network
Server Farm Detail for LBR setup:
Server 1 (EBS App1 Node, ap1ebs):
IP : 172.25.45.19
Server Name: ap1ebs.xxxx.lk [ap1ebs hostname is an example, actual hostname will be use]
Protocol: http
Port: 8000
Server 2 (EBS App2 Node, ap2ebs):
IP : 172.25.45.20
Server Name: ap2ebs.xxxx.lk [ap2ebs hostname is an example, actual hostname will be use]
Protocol: http
Port: 8000
Since my client needs to access URL ebiz.xxxx.lk which should be resolved by IP 172.25.45.21 (virtual IP) via http (80) before they deploy the app on the two servers I just ran web service on both servers (Linux) and was trying to access http://172.25.45.21 it was working fine and gave me index.html page. Now after my client has deployed the application then when he tries to access the page http://172.25.45.21 he cannot see his main login page. But still my testing web servers are there on both servers when I type http://172.25.45.21 it will get index.html page, but not my client web login page. What can I do for this ?
Following are my latest config :

ACE 4710: Possible to allow a user to clear counters but nothing else?

Hello all,
Using an ACE 4710 we have a user setup with the Network-Monitor role which allows the user to view config, interface status, etc. We would also like to allow this user to clear the interface error counters as well, but nothing else. Is this possible?
Thanks!

Hello Brandon-
Network-Monitor only lets you browse outputs, it is a not a role that allows a user to make any changes including clearing stats. You can create custom roles and domains to get closer to what you want, but you cannot zero in on a single command like that.
i.e.
ACE# conif t
ACE(config)# role MyRole
ACE(config-role)# rule 1 permit modify feature ?
AAA             AAA related commands
access-list     ACL related commands
connection      TCP/UDP related commands
fault-tolerant Fault tolerance related commands
inspect         Appln inspection related commands
interface       Interface related commands
loadbalance     Loadbalancing policy and class commands
pki             PKI related commands
probe           Health probe related commands
rserver         Real server related commands
serverfarm      Serverfarm related commands
ssl             SSL related commands
sticky          Sticky related commands
vip             Virtual server related commands
You can create a permit or deny rule, within that, create/debug/modify/monitor each feature seperately.
Domains allow you to create containers for objects. You can place specific rservers, serverfarms, etc. into it - then apply it to a role so that the user assigned to it can only touch those objects.

Chris Higgins

ACE 4710 in bridge mode not working

I am trying to configure ACE 4710 bridge mode and I am stuck up in physical interface configuration. I have configured gig1/2 of ACE as trunk port and on layer 2 switch I have assigned that interface (gig1/2) to VLAN 11. I tried trunk port also but it got disabled due to BPDU error.

" I tried trunk port also but it got disabled"   <----- if your L2 config is not correct, nothing will work.
What is the setup on the switch ? Trunk or access vlan ?
What is the status of the interface ? up ? down ?
Do you see something in your arp table ?

ACE 4710 Connectivity help?

I'm using an ACE 4710 in a new datacenter, with the following setup:
2/4 physical ethernet interfaces port channeled into port-channel 1
2/4 physical ethernet interfaces port channeled into port-channel 2
I have the following vlans defined:
1001 - admin - interface ip: 10.53.136.70
400 - client side - interface ip: 10.53.136.100
500 - server side - interface ip: 192.168.128.1
999 - fault tolerance - interface ip: 192.168.11.2
My problem is I am trying to nat ssh and web server traffic from the client side, to the server side, but it's never getting to the server. For example, if I ssh to 10.53.136.102, it times out. (10.53.136.102 should get nat'd to 192.168.128.2)
Also, I can connect to the ACE 4710 via telnet using 10.53.136.70, but cannot connect to 10.53.136.100.
I'm thinking there is either something wrong with the port-channels, or the access lists. On the other hand there could be something wrong with the nat'ing, but I had it working before switching over to the port-channels.
Any thoughts?
Thanks,
Brent

I've attached the two contexts which we are using. The admin context is new_lb_config.txt and the second context where the loadbalancing occurs is in the new_lb_config_VC_WBPX.txt file.
From the load balancer, I am able to ping the real server ips in the 192.168. ip range. The 4710 recognizes that they are in service.
I believe the ACL for the VLAN 400 is set to permit all traffic, but I don't know if the service policies are preventing something from happening.
Right now, I have disconnected the two 4710s and I am only working on one of them to see if I can get the basic connectivity going. Once I accomplish that, I will work on high availability. I'll have to check whether it thinks it is in passive mode...not entirely sure how to do that, but I will check it out.
Thanks,
Brent

ACE 4710 HTTP Probes

Using the ACE 4710 for loadbalancing a Sharepoint site.
We currently have a HTTP probe setup to check the port 80 status of the rserver.
Is there anyway to get the HTTP probe to check a DNS entry for each of the application sites? For instance http://info vs http://site are two different web sites running on the same IP. One site could have a problem but the actual port 80 for the IP may be still alive.
Thanks for any information.

Has anyone figure this out? I am tring to get healthchecks/probes setup in this same fashion. I have 2 servers with 1 IP but have many sites. I want to probe each side and ensure I get a 200 code. I also have to provide credentials to the site. It seems that if i open IE I can log in just fine to the site with the credentials. However there is an active x control box that is wanting to be installed. When I set this up on my ACE it seems I am getting a http 401 unauthorized error. I have done a wireshark capture while I was browsing and I see the 401 however it also reports a 200 code after that. Do you think this is a problem because of the active x control wanting to be downloaded? Or is this an issue with the first http code that is recieved by the probe, that being the 401 and then the 200? Below is my config (cleaned of course).

ACE 4710 HTTPS load balance configuration

Have two ACE 4710 in HA setup. We would like to setup HTTPS loadbalance(actually just a primary and standby configuration in the serverfarm). Initially this would be for Exchange OWA connections but may expand to more HTTPS connections later.
I know there are several ways to do SSL with the ACE( client, server, end-to-end). I am just wanting to know the easiest way to deploy this? Is a certificate always needed on the ACE for each connection? In HA mode would a certificate be needed for both or does it replicate in some way to the other ACE?
Any configuration examples would be helpful.
Thanks.

IF you terminate SSL on the ACE you need certificates and key on ace in the context in which you are doing the termination. The certs and keys need to be installed on the active and standby (manually unless using anm to manage).
when speaking of SSL
SSL termination refers to ace terminating SSL and sending to server as clear text
end to end - ACE terminates SSL (to look into payload to make a loadbalance decision or sticky decision) and then re-encrypts to the server, so to the client ACE is an ssl server and to the server the ace is an ssl client.

ACE 4710 - can I dynamically sticky all traffic to 1 server based on URL?

Hello all, I'm new to the ACE 4710 and need to know some details about stickyness.
As background, we are a small company with a SaaS product and a pair of webservers.
I have set up the loadbalancing default L7 Load-balancing rule to sticky based on a Cookie based Stickey Group.
That seems to be working and session traffic is sticking to a server during the user's session.
Based on a request from our outsourced developer they would like the Loadbalancer to not only sticky the users sessions, but also sticky a url to a server.
I would like this to happen dynamically as each of our clients will have their own url based on our standard domain like clientname.fixeddomain.com and I don't want to have to come back to the loadbalancer every time we add a client.
As I said, I'm new to these devices but understand the concepts, and am in the position of having to make it work little to no tranining on this hardware and no budget at this point to pay someone else for configuration and setup.
I just need to know at this point if I can stick all requests for a specific URL to a server to avoid caching issue while those sessions are active and have new connections to other client urls balanced among the webservers.
Hopefully this request makes sense.
Thanks,
Mark Steeves.

Daniel,
Thanks for the reply, but I cannot reach the URL you included. It gives me a 403.
Therfore without reading the article, I wanted to ask if the proper setup would be:
1. Default L7 load-balancing action: Primary action: Sticky: Stickey Group using
Type = HTTP Header: Header name = Host
2. Server Farm: Predictor: Least Connections or Round Robin to distribute the load between the 2 web servers.
Using this setting in testing, it looks like all the traffic keeps going to 1 server only. Granted there is not much traffic t the servers, but I have 2 different url being tested. url1.ourdomain.com & url2.ourdomain.com
If you have another link for the above document, please let me know.
Thanks,
Mark Steeves.

Ace 4710 - same context routed and load-sharing

Hi All
Can an ACE 4710 have , in the same context - servers which are
a. just being routed to
b. a set of load-shared servers
I have been told you may not be able to do this on this version
Does anyone know if this is correct
Thanks
Steve

Hi Boris
I have been on the ACE course and before we install the 4700 box i have been
asked to set up a test setup.
This would involve have a context which would have one ip address range and
a few pcs (pretending to be servers ) and one which would be just routed.
A colleague of mine seemed to think that something had been said on the course
to the effect that if the ACE was deployed in line the you couldnt have some
of your servers in load-sharing and some just routed on the same subnet and
in the same context.

Rservers initiated traffic not sourcing the traffic as VIP in Ace 4710

One of the feature of our application is that our Application Server initiate text message to our devices sourcing from UDP 1120 and device need to see the message come from a specific pubic IP (2.2.2.2) with UDP port 1120 and reply back with the same Public IP (2.2.2.2) with UDP port 1120.The problem is we can make that happen if we have only one server in our ACE Serverfarm when we do a SNAT the real servers with the VIP address (10.1.246.32) but it does not work when we have more than one server in the Serverfarm. Since we have 2 servers, i cannot nat the real servers with the VIP address, if I do a PAT, obviously it is changing the source port of the request.
Note: This setup is working fine with the Cisco Content Switch module running on chasis 6509. When I sniff the traffic initiated from the server coming the CSM load balancer, it is sourcing the traffic as the VIP and the source port remains the same by default but this is not the case with ACE 4710
Traffic flow as follows

I see in CSS, they are able to nat the source ip address with VIP and port-mapping diabled. How do I implement
portmap disable in ACE 4710
Disabling Port Mapping
By default, the CSS NATs source IP addresses and PATs source ports for a configured source group. If you configure the portmap disablecommand in a source group, the CSS performs NAT on the source IP addresses but does not perform PAT on the source ports of UDP traffic that matches on that source group.
For UDP applications with high-numbered assigned ports (for example, SIP and WAP), we recommend that you preserve those port numbers by configuring destination services in source groups instead of using the portmap disable command. Destination services cause the CSS to NAT the client source ports, but not the destination ports. For information about configuring destination services,

ACE 4710 not responding

Hi,
We have to ACE 4710 device in our network and we have facing device hung issue in our Primary ACE. We are not able to get management access or direct console access to the device when the issue is happened and also we are not able to reach the vlan interface IP or/VIP.

ACE 4710 lic'd performance

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
or
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
thanks,
Sez

Hi Sez,
The license applies to the overall throughput, both routed and load-balanced traffic.

ACE 4710 - need help configuring backend server monitoring

Currently running an ACE 4710, which is handling all of our inbound SSL connections and then forwarding requests thru
to backend web servers. This all works fine.
My question is this..Right now we are not load balancing any of the backen web servers. But I now have a requirement that should
a web server crash or become unavailable I need to redirect that backend connection to another web server.
Scenario is more like I have 2 web servers both serving same content, but I want one server to take all the connections unless it fails, at that point
have all the connections forwarded to 2nd server.
Is there a way to setup the load balancing where the 1st server gets all the connections until a failure happens ?
Any help would be appreciated.
Cheers
Dave

Hi Dave,
You can use sorry-server or backup server feature. details can be found at
