Cisco ACE with ACS5.0

Guys,
Is there a way that I can configure authentication using ACS 5.0 to access a certain server farm group only for a specific user?
Sent from Cisco Technical Support iPad App

Yes you could using roles & domains. you would initially have to configure a domain on the ACE and add the relevant serverfarm to it.
Then in ACS configure the policy for authentication & authorization and under the Shell Profile / Custom Attributes section add an attribute of shell: with Value of , similar to what I have below for my environment (I just have a role of Admin and the default domain in mine). Then you can test by logging in and issuing the 'show users' command to verify (or check ACS Tacacs/Radius logs)

CISCO ACE issue with MIBs

Dear All,
I know this might have discussed here million times.. but still i am behind this to get this done due to BU pressure to do the capacity management.
I am trying to get the following using SNMP
1) Real Server
2) Real Server Current Connection
3) Real Server IP address
I tried it with following MIBs and OIDs
CISCO-SLB-MIB
slbRealServerFarmName               .1.3.6.1.4.1.9.9.161.1.3.1.1.1
slbRealIpAddress                          .1.3.6.1.4.1.9.9.161.1.3.1.1.2
slbRealNumberOfConnections         .1.3.6.1.4.1.9.9.161.1.3.1.1.5
CISCO-ENHANCED-SLB-MIB
cesRserverName                         .1.3.6.1.4.1.9.9.470.1.1.1.1.1
cesRserverIpAddress                    .1.3.6.1.4.1.9.9.470.1.1.1.1.4
cesRserverCurrConns                   .1.3.6.1.4.1.9.9.470.1.1.1.1.19
Either of these MIBs /OIDs return any value.
When i raise a TAC case i got the information saying these cannot be retrieved.
Is there any way i can get these values from ACE MODULE , because this is very much required for the BU and they are behind us since long time.
Apppreciate support from all.
thanks,
Parvees

Hi Parvees,
I wasn't looking for values you're interested in, but everything you can get with show command you can get via HTTP(s) request in XML using .
For example, here's a "sh serverfarm ServerFarm1" query:
$ curl --user USER:PASSWD -d "xml_cmd=CONTEXT\">xml-show on%0A show serverfarm ServerFarm1" http://ACE_IP_ADDRESS/bin/xml_agent
I'm running curl on linux box, but I think it is available on other platforms. The code above is a one-line command, but you can write scripts/lists of commands and send them to your ACE with curl.
Here's a link provided in a neighbour discussion that gives more information: https://supportforums.cisco.com/docs/DOC-17849
Hope this help,
Alex

Monitoring the Cisco ACE module with SNMP

We use 2 redundant Cisco ACE loadbalancer in our datacenter
The models are ACE20-MOD-K9 with software A2(2.0)
Does anybod know how to monitor the environment (cpu, memory) of such a module with snmp?
We were not able to find an applicable MIB for that module.
The CISCO-PROCESS-MIB.oid (ftp://ftp.cisco.com/pub/mibs/oid/CISCO-PROCESS-MIB.oid) seems not to reflect the correct oid's.
What are the correct oid's for cpu and memory?
Where can I find a detailed documentation for snmp-monitoring the cisco ace module?
thanks

Hi Patrik,
to monitor the ACE I use these two MIB's:

Cisco ACE compatiblity with F5 GTM

Hi,
We have cisco ace 30 modules installed in cisco 6500 switches. For application availability purpose from the internet, we need to have some global site selector/3rd party devices with similar feature set that of cisco gss.
My question is: whether cisco ace is compatible to ge tintegrated with other 3rd party devices like F5 GTM?
kindly sugegst..

Good afternoon,
I'm not familiar with the GTM solution, but, as long as it's DNS-based like the GSS, it should be perfectly compatible. Bear in mind that the ACE is not aware on how clients are getting the IP address, it just replies to whatever connections it gets.

Daniel

Cisco ACE Module with Bluecoat Cache Proxy, Transparent and spoofing client IP

Hello Dears,
I'm trying to implement Cache loadbalancing through Cisco ACE Module.
I have 2 Bluecoat cache proxies, when i do configure transparent proxy without spoofing client IP, everything work properly, but when I enable spoofing client IP (reflect client IP address), clients are not able to access internet, although they are going to cache servers, I can see their sessions.
I'm afraid that I have a problem in the returned traffic PBR.
can anyone help please.
Thanks

Hi Ibrahim
I ahve reviewed the config. The ACE config is all god but I do see some issue with the switch side. If you are doing ip spoofing, then "match ip address" in pbr should be the client ip address. However, what you did is ip address between the ACE and MSFC. Try to configure the test client ip address into the below access-list.
msfc---vlan 265---ACE--vlan 264----CE farm

TCP SYNSEEN with load balancing Cisco ACE 4710

I have a Cisco ACE 4710 load balancing the traffic to two proxy servers, the configuration is the same since December 2012, but yesterday it stated to show SYNSEEN in the show conn command, and the hosts cannot browse. I think that means that the three-way-handshake is not complete.
If I bypass the ACE the hosts can browse without problems.
I have tested with another ACE appliance and the same configuration but the behaviour is the same.
I need help as soon as possible,
thanks,
I've attached the Show conn, show conn detail and show run.

Hi Cesar,
Thank you for your answer,
The issue was solved,
We were running an A3 software version, it seems to have a Bug so it doesn't show the NAT commands in the "show run", so when we made the configuration backup we didn't noticed it.
The ACE reloaded because an electrical failure so it losted the NAT config.
We just upgraded to an A4 version and also added a NAT/PAT to enable the communication between the Clients and the Proxy.
Regards,

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 ?

Urgent!!! Cisco ACE and asymetric routing assistance needed

I am wondering if someone can give me pointers on the cisco ACE
and asymetric routes. I've attached the diagram:
-Cisco IOS IP address is 192.168.15.4/24 and 4.1.1.4/24
-Firewall External interface is 192.168.15.1/24,
-Firewall Internal interface is 192.168.192.1/24,
-F5_BigIP External interface is 192.168.192.4/24,
-F5_BigIP Internal interface is 192.168.196.1/24 and 192.168.197.1/24,
-host_y has IP addresses of 192.168.196.10/24 and 192.168.197.10/24,
-Checkpoint has static route for 192.168.196.0/24 and 192.168.197.0/24
pointing to the F5_BigIP,
-host_y is dual-home to both VLAN_A and VLAN_B with the default
gateway on host_y pointing to VLAN_A which is 192.168.196.1,
-host_x CAN ssh/telnet/http/https to both of host_y IP addresses
of 192.168.196.10 and 192.168.197.10.
In other words, from host_x, when I try to connect to host_y
via IP address of 192.168.197.10, the traffics will go through VLAN_B
but the return traffics will go through VLAN_A. Everything
is working perfectly for me so far.
Now customer just replaces the F5_BigIP with Cisco ACE. Now,
I could not get it to work with Asymetric route with Cisco ACE. In
other words, from host_x, I can no longer ssh or telnet to host_y
via IP address of 192.168.197.10.
Anyone knows how to get asymetric route to work on Cisco ACE?
Thanks in advance.

That won't work because ACE uses the vlan id to distinguish between flows.
So when the response comes back on a different vlan, ACE can't find the flow it belongs to and it drops it.
Even if we could force it to accept the packet, ACE would then try to create a new flow for this packet and it will collide with the flow already existing on the frontend.
You would need to force your host to respond on the same vlan the traffic came in.
This could be done with client nat on ACE using different nat pool.
Gilles.

Cisco ACE loadbalancing matching more than one header in L7 class map

Dear All,
This is regarding Cisco ACE loadbalancing matching more than one header in L7 class map. I have a small setup with ACE 30 module in Cisco6500. I have got three webservers. Presently I have following configuration where I am mathing one url header.
class-map type http loadbalance match-all L7_WEB_HEADER_MATCH
description MATCH THE HOST HEADER OF HTTP REQUEST
2 match http header Host header-value ".*abhisar.com*"
So for above configuration, when traffic is coming for abhisar.com, it is working fine.
Now, I have following headers and DNS entry is pointing to same virtual IP for all http url header same as abhisar.com
abhisarindia.com
indiaabhi.com
So new configuration will be
class-map type http loadbalance match-any L7_WEB_HEADER_MATCH
description MATCH THE HOST HEADER OF HTTP REQUEST
2 match http header Host header-value ".*abhisar.com*"
4 match http header Host header-value ".*abhisarindia.com*"
6 match http header Host header-value ".*indiaabhi.com*"
So just want to confirm if this is fine.
Thank You,
Abhisar.

Dear Rajesh,
Thank you for reply. I will let you know once I carry out this activity.
Thank You,
Abhisar.

Slow connection in one server if accessing through Cisco ACE

Hi Earsdale,
All the three servers are using the same configuration, so, I'm afraid it's not possible to give you a simple answer. You will need more troubleshooting.
I would recommend you to start by checking the differences between the servers because one of those differences is certainly causing the failure.
Also, it would be helpful to get traffic captures on the TenGig interface of the ACE to compare the behavior of the connection when going to the different servers, as well as the differences when being load-balanced vs accessing the server directly.
If you need help with this troubleshooting, you can always open a TAC service request

Cisco ACE dynamic rerouting (dc to dc failover)

Good day,
We currtenly have two dc's (site A and site B)
We are using netapps as our SAN and we ar booting our server directly from the SAN
SAN A and SAN B are insync and the network between site A and site B is routed.
The challange:
When a server is failover from site A to B it still has an ip adress that is routed to site A.(due to the SAN boot)
We have a cold - hot design in regards to the servers (so no clustering of ESX)
I have been reading about cisoc ACE and i think that it would solve the challange by dynamily updateing OSPF.
Can any one please confirm that cisco ACE will solve this challlange (whitout the need for any other additional hardware)
Thanks a lot,
Regards,

It's more related to disaster recovery planning than ACE configuration
The cleanest way is to use L2 extension.
Otherwise you can use VMWare SRM to change the ip addresses of your VMs, or run an OSPF process and replicate all the subnets and put it in the "shutdown state" (or announcing it with a very high cost, proximity routing will do the rest - ACE module can do this for the VIPs with OSPF route health injection, ACE4710 doesn't support RHI but on the upstream router you can define an IP SLA probe and perform conditionnal redistribution), or use a dummy VRF with all your subnets and when enabling DRP, perform route leaking... use NAT with DNS-based failover etc...
There is no generic answer to your problem.

Cisco ACE - "show conn" command queries

Hi all,
i have some queries regarding the "show conn" command in Cisco ACE.
Working Scenario:
VIP : 10.10.10.1
Server 1 : 10.10.20.1
Server 2 : 10.10.20.2
Client: 30.30.30.1
When a client 30.30.30.1 initiates a connection to the VIP on 10.10.10.1, the ACE load balances it to Server 1, 10.10.20.1. Looking at the "show conn" table, it shows that Server 1 is replying back to the Client 30.30.30.1 through the ACE.
Now, my question is when the ACE returns the traffic to the Client, should the Client be seeing the source IP coming from the VIP or Server 1? My understanding is that the Client should be seeing traffic returning from the VIP. But the show conn table does not seem to suggest so.
show conn table
conn-id    np dir proto vlan source                destination           state
----------+--+---+-----+----+---------------------+---------------------+------+
1768       1 in TCP   10   30.30.30.1:9221   10.10.10.1:80       ESTAB
41         1 out TCP   52    10.10.20.1:80    30.30.30.1:9221   CLOSED

Daniel,
The client is expecting a response from the VIP otherwise there would be an asymmetrical routing problem and conns will never complete.
The fact that you're seeing 30.30.30.1 as the destination address is just that the server is able to see client's IP address on the request, when your backend servers sends the reply back to the client this response is forced to go through the ACE, when the ACE looks at the packet it matches with a previously conn created on the flow table so it "NATs" the reply so now the source of the packet is the VIP and destination is 30.30.30.1.
This is a expected behavior as you're not using S-NAT on your network.
HTH.

How to monitor memory on Cisco ACE Appliance 4710?

I'm trying to monitor the memory usage in balancers Cisco ACE Appliance 4710 with version A3 (2.2), but the OIDs cpmCPUMemoryUsed (.1.3.6.1.4.1.9.9.109.1.1.1.1.12) and cpmCPUMemoryFree (.1.3.6.1.4.1.9.9. 109.1.1.1.1.13) not work.
What the right OID to monitor memory usage in balancers Cisco ACE 4710 Appliance?

HI,
You need to use CISCO-ENHANCED-SLB-MIB .
cpmProcExtMemAllocatedRev .1.3.6.1.4.1.9.9.109.1.2.3.1.1 (this gives the memory allocated to each process)
You can also read up on the mib
Hope this helps

Cisco ACE appliance backend Requests

Hi,
I have a question about the Cisco ACE 4700x appliances.
I hope that someone can help me out with the next question please, which is:
does the appliance support backend server selection based on URL, hostnames or IP?
if yes, where can i find more details about it ?
Thank you

Here it is.

VPC / Cisco ACE and the Nexus 2K and 5K

Hi all,
So we have a test environment that looks like the following. We have 2 5K's switch 1 and switch 2. Switch 1 has two 10gb connections downstream to a 2K and switch 2 has two 10Gb connections downstream to the other 2K. We have a few servers that are multi-homed with LACP and VPC via the 2Ks and it works a treat.
We have our Cisco ACE 01, ports 1 and 2 going to one of the 2K's and we have ports 3 and 4 going to the other 2K, ACE02 ports 1 and 2 going to one of the 2K's and we have ports 3 and 4 going to the other 2K. If i enable VPC and none LACP based etherchannel i cannot get the ACE's talking to each other, but looking at the VPC status its all healthy and up.
Has anyone managed to multi-home the ACE between two 2K's with VPC successfully?
If I disable the links so each ACE only has links upstream in a traditional port-channel and not cross connected, the ACE's can see each other with no issues.
Cheers

Doh.. so we had a cable patching issue in the end. Let this be a lesson to all networking chaps - always check the basics first! Now we have patched the cables as per design the VPC has been established and works.
Now we have VPC is working we are simulating link failures. When we restore a shutdown physical port within the port-channel/VPC that sits between the 2K and ACE (simulating a port failure) the ACE's lose sight of each other for about 10 seconds and causes an short outage until the port is up and up. The logs on the ACE show 'the Peer x.x.x.x is not reachable. Error: Heartbeat stopped. No alternate interface configured' but the VLAN for the FT interface is carried over all four ACE NIC's that are multi-homed to two 2K's... very strange, i would not expect this, it's like the MAC addresses for the FT interface are waiting to be timed out on the 2K until they are switched on another interface within the port-channel and VPC.
Anyone seen this before?
