Cisco ACE Inspecting RTSP Wowza Service?

Did somebody knows if Cisco ACE in some of their HW and SW versions support Inspect for RTSP of Wowza Service running in the serverfarm? We intend to setup the service in routing mode and without a Firewall or a Web APP Firewall avoiding BW consumption in ASA/FWSM.

Hi Samuel,
ACE does support RTSP inspection but specific server support is not mentioned. Please see more details about RTSP inspection at below:

How can ftp service on non-standard port be load balanced using Cisco ACE.

How can ftp service on non-standard port be load balanced using Cisco ACE.For example ftp service required on tcp 2000 port

Hi Samarjit,
you can do this by specifying the port number in the class map that you create . Please find the below mentioend config guide where you can specify the tcp/udp port , range or ports or even the wild card to match the port.

ACE and RTSP over UDP

I have a VIP that is not able to stream RTSP over UDP. TCP streaming works fine, but when I configure UDP on the Real client no UDP packets are even processed by the ACE.
When I configure 'inspect rtsp' on the class, then TCP streaming also breaks. I am using A2.10.
Anyone got any hints on where I am going wrong ?

I have never got a chance to play with ACE + RTSP over UDP but
As per
http://www.cisco.com/en/US/docs/interfaces_modules/services_modules/ace/v3.00_A2/configuration/slb/guide/classlb.html#wp1165238
ACE supports RTSP over TCP Loadbalanacing only.
Similarly for RTSP Inspection its clearly stated at
http://www.cisco.com/en/US/docs/interfaces_modules/services_modules/ace/v3.00_A2/configuration/security/guide/appinsp.html#wp1318637
For RTSP inspection
The ACE supports TCP only in conformity with RFC 2326.

DNS Inspection Denial of Service Vulnerability check

Hi Everyone,
I am checking this cisco link ---http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20131009-asa for
DNS Inspection Denial of Service Vulnerability
Cisco ASA Software is affected by this vulnerability if the DNS Application Layer Protocol Inspection (ALPI) engine is configured to inspect DNS packets over TCP.
To verify if the DNS ALPI engine is inspecting DNS packets over TCP, use the
show running-config access-list <acl_name>
command where
acl_name
is the name of the access-list used in the
class-map
to which the DNS inspection is applied.
This can be found by using the
show running-config class-map

Hi,
The post says this
Cisco ASA Software is affected by this vulnerability if the DNS Application Layer Protocol Inspection (ALPI) engine is configured to inspect DNS packets over TCP.
So it says that if the ASA is configured to inspect DNS over TCP then its vulnerable.
It also says
Note:Cisco ASA Software will not inspect DNS packets over TCP by default.
And it seems you have not made any special configurations related to DNS inspection therefore your ASA should not be inspecting DNS that is using TCP therefore it should not be vulnerable. Atleast that is how it seems to me.

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 ?

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

Daniel

Logging user commands in Cisco ACE appliance

Good afternoon gentlemen
I need to configure the same as shown below in Cisco ACE Appliance. The requirement is logging all user access login (whether failed or succeeded) and also logging all commands that users issue.
#IOS commands
no logging console
logging buffered 307200 informational
service timestamps log datetime localtime show-timezone
logging trap debugging
login on-failure log
login on-success log

If you guys have an idea please answear
Regards
Christian

Hello Arun,
we saw before the message you report, it's probably a symptom of:
CSCtx03563
or
CSCue38032
I would suggest opening a TAC case to get this properly investigated.

DNS Inspection Denial of Service Vulnerability

Advisory ID: cisco-sa-20131009-asa
http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20131009-asa
I have a Pix running version 8.0.4 with the following configuration:
inside interface:      192.168.231.254/255.255.255.0
outside interface:     10.100.2.254/255.255.255.0
no nat-control
access-list test permit ip any any log
access-group test in interface outside
access-group test in interface inside
I have a window 2008R2 residing on the Internal interface of the firewall. The domain controller resides on the outside interface of the firewall.
I went ahead and implement the change recommended by Cisco
access-list DNS_INSPECT extended permit udp any any
class-map DNS_INSPECT_CP
   match access-list DNS_INSPECT
policy-map global_policy
   class DNS_INSPECT_CP
     inspect dns preset_dns_map
However, after implement the workaround, my windows 2008R2 machine on the inside network can NOT join with AD on the outside network.
on the log of the firewall I see this:
Oct 31 14:34:09 192.168.231.254 %PIX-4-410001: Dropped UDP DNS request from inside:192.168.231.180/61780 to outside:10.100.2.128/389; label length 132 bytes exceeds protocol limit of 63 bytes
Oct 31 14:34:17 192.168.231.254 %PIX-4-410001: Dropped UDP DNS request from inside:192.168.231.180/61780 to outside:10.100.2.128/389; label length 132 bytes exceeds protocol limit of 63 bytes
I even change the DNS maximum length to 8192 but it still does not work.
I remove the recommendation from the configuration, everything works fine after that.
Anyone knows why?
Thanks in advance

How to test a cisco ACE loadbalancer.

Hello guys, I am new on this site. I have deployed a Cisco ACE 4710 loadbalancer, and it is loadbalancing 2 real servers. Is there any way or commands I can use to see if it is loadbalancing properly.

"show serverfarm" will show you the load-balanced connections to each real. Also try "show service-policy <> class-map <> detailed" and check client and server hits counts.
"show connection" also.

QoS Cisco SCE8000, Caching Cisco IronPort WSA, Loadbalancing Cisco ACE solution

Hi all,
Our customer is a mobile operator. They need a integrated solution for caching, QoS and Loadbalancing in a combination. From my understanding of their goals, they need to providing stable and speedy broadband access as well as good user experience by the differentiation service offering. They need to classify IP traffic and prioritize and control of content-based services for a given subscriber while transparently and dynamically redirect and load balance the application level classified of IP traffic to a proxy caching server regardless of protocols such as http, https, ssl, ftp, flv, mms and rstp, sip, p2p....
Attached pls find the RFP and technical specification for Caching and QoS.
I appreciate your expertise to consult me whether I can propose for them the Cisco ACE standalone appliance or ACE engine module for 7600/6500 for loadbalancing, Cisco IronPort WSA for caching and dual Cisco SCE8000 for QoS as an integrated solution. Is this solution feasible/workable and where could I find the same reference or solution design or technical guidance on this?
Thanks a lot and would like to hear from you at the soonest!
Best regards,

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
interface vlan 265
description Interface_With_MSFC_SUBS_2_INTERNET
ip address 168.168.1.52 255.255.255.248
access-group input PERMIT_ALL

T3 Oracle´s proprietary tunneling protocol and Cisco ACE

Does anybody know if it is possible to load balance the T3 Oracle´s proprietary tunneling protocol supported by Oracle Weblogic with Cisco ACE?
TIA,
Claudio Uemura

HI Claudio,
I don't know much about T3 protocol, in short you can load balance almost anything really, the issue becomes to how granular and if you can do any intelligent inspection besides source and dest ip and if there are multiple different connections on different ports. These last points sort of decide whether it's worth it.
- If you find the specifics about the connection ( port, type of protocol and type of connection ( long-lived or short lived) you should be able to setup a basic rule to test. A sniffer trace will give you the most information if oracle website does not explain T3 in detail.
- From a quick search there also looks to be a method to encapsulate T3 inside a http packet on weblogic servers, if this were the case then you could do some deep packet inspection with regex etc to get more granular load balancing
http://forums.oracle.com/forums/thread.jspa?threadID=706909
I would think it's defintely worth looking at both options
cheers,
Chris

FAQ

Is there a Cisco lab available for ASR 9000
we have "XR4U" stations coming available soon when XR 511 comes alive. The plan is for a downloadable play image like that. In the interim we have 2 demo systems available, and they can be booked via your account manager representative.
How will MOD160 perform with multiple 9000NVS?
very well. the mod 160 has 4 NPU's, 2 per bay. So if you have a 4x10 MPA to serve a satellite, you effectively have a single NPU per 20 1Gigs from the satellite. The pps performance will be stellar. However it might be price technically more ideal to connect satellite with a 36x10. Since the MOD-x has native MPA's with 1G also.
2. Is there a shortcut for a Bundle-EthernetX interface, such as port-channel interface (poX), in Cisco IOS® ?.
usability enhancement is there, we are trying to push this into a new reasonable release. follow CSCuh04526
3. What is the revolutions per minute (RPM) on these hard disk drives (HDDs) compared to the solid state drives (SDDs)? Will the spinning drives be slow?
depends on the type we had avaialble at time of production, you will see different sizes and disks on the RSP2. the rpm of the HD is not so much an issue as much as the buffered writing we used to do in XR. This is fixed up with XR43 where the disk writing performance is much better. the HD/SDD is used for logging storage only (and maybe your pictures) but other then that we're not that concerned with write perf of the HD.

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.
