wccp configuration for SSL Orchestrator
Web Cache Communication Protocol (WCCP) is a Cisco-developed content-routing protocol that provides a mechanism to redirect traffic flows in real-time. It has built-in load balancing, scaling, fault tolerance, and service-assurance (failsafe) mechanisms. Cisco IOS Release 12.1 and later releases allow using either Version 1 (WCCPv1) or Version 2 (WCCPv2) of the protocol. Well that's a mouthful; to say basically that WCCP is a Cisco developed protocol designed to load balance traffic among proxy web cache servers. The beauty of it is it’s really easy to set up on a router (and Cisco Firepower) and can intercept outbound traffic and redirect it to the proxies. The proxies do not need to be in the network path. It’s basically a form of policy based routing. And if the proxy servers are down, the router will just continue to forward the traffic down the default route. This makes it relatively easy for SSL Orchestrator to receive traffic. But I can say there’s not exactly the greatest documentation from either organization. But it's really pretty simple. The fun fact is, once your device is registered with the WCCP group on the router, it just works. As in, it just starts sending any traffic that matches the ACL off to the router. Now as for HA. WCCP was designed to handle the HA. Right? I have a pool of web caches and I’m distributing the traffic among them. But if I set up the BIG-IP using its standard Active/Standby HA and configuration sync, there’s some additional thought that comes in to play. With a configuration where both devices in the BIG-IP HA pair and each designates its local self-ip as the local tunnel address. There can be a delay while the newly active device registers with the WCCP group on the router. It’s a short blip. But a blip nonetheless. But what about using the floating IP address? Isn't that used to provide a movable HA address? Yes. Yes, it is on a normal network segment. Similar to VRRP. 01070734:3: Configuration error: In wccp /Common/wccpsg service tunnel local address (192.168.8.222) cannot be a floating self IP So you’re denied from configuring the floating self-ip from being the target. The reason is, these are treated as tunnel interfaces and in the case of using the GRE configuration for WCCP, it is a tunnel! So, peering is done between each device individually in the HA group. That means, though, that only the active device will register. What that means for failover then is that the active device registers and the standby does not. When a failover event happens, the newly active device registers and the inactive device drops out. modify net wccp wccpsg { services add {90{ hash-fields {src-ip} port-type dest ports add { 443 } redirection-method l2 return-method l2 routers add { 192.168.8.128 } tunnel-local-address 192.168.8.105 tunnel-remote-addresses add { 192.168.8.128 } } } } The most important thing is that the service group number matches.

What is F5 ACI ServiceCenter? F5 ACI ServiceCenter is an application that runs natively on Cisco Application Policy Infrastructure Controller (APIC), which provides administrators a unified way to manage both L2-L3 and L4-L7 infrastructure in F5 BIG-IP and Cisco ACI deployments. Once day-0 activities are performed and BIG-IP is deployed within the ACI fabric, F5 ACI ServiceCenter can then be used to handle day-1 and day-2 operations. F5 ACI ServiceCenter is well suited for both greenfield and brownfield deployments. F5 ACI ServiceCenter is a successful and popular integration between F5 BIG-IP and Cisco Application Centric Infrastructure (ACI). This integration is loosely coupled and can be installed and uninstalled at anytime without any disruption to the APIC and the BIG-IP. F5 ACI ServiceCenter supports REST API and can be easily integrated into your automation workflow: F5 ACI ServiceCenter Supported REST APIs. Where can we download F5 ACI ServiceCenter? F5 ACI ServiceCenter is completely Free of charge and it is available to download from Cisco DC App Center. F5 ACI ServiceCenter is fully supported by F5. If you run into any issues and/or would like to see a new feature or an enhancement integrated into future F5 ACI ServiceCenter releases, you can open a support ticket here. Why should we use F5 ACI ServiceCenter? F5 ACI ServiceCenter has three main independent use cases and you have the flexibility to use them all or to pick and choose to use whichever ones that fit your requirements: Visibility F5 ACI ServiceCenter provides enhanced visibility into your F5 BIG-IP and Cisco ACI deployment. It has the capability to correlate BIG-IP and APIC information. For example, you can easily find out the correlated APIC Endpoint information for a BIG-IP VIP, and you can also easily determine the APIC Virtual Routing and Forwarding (VRF) to BIG-IP Route Domain (RD) mapping from F5 ACI ServiceCenter as well. You can efficiently gather the correlated information from both the APIC and the BIG-IP on F5 ACI ServiceCenter without the need to hop between BIG-IP and APIC. Besides, you can also gather the health status, the logs, statistics etc. on F5 ACI ServiceCenter as well. L2-L3 Network Configuration After BIG-IP is inserted into ACI fabric using APIC service graph, F5 ACI ServiceCenter has the capability to extract the APIC service graph VLANs from the APIC and then deployed the VLANs on the BIG-IP. This capability allows you to always have the single source of truth for network configuration between BIG-IP and APIC. L4-L7 Application Services F5 ACI ServiceCenter leverages F5 Automation Toolchain for application services: Advanced mode, which uses AS3 (Application Services 3 Extension) Basic mode, which uses FAST (F5 Application Services Templates) F5 ACI ServiceCenter also has the ability to dynamically add or remove pool members from a pool on the BIG-IP based on the endpoints discovered by the APIC, which helps to reduce configuration overhead. Other Features F5 ACI ServiceCenter can manage multiple BIG-IPs - physical as well as virtual BIG-IPs. If Link Layer Discovery Protocol (LLDP) is enabled on the interfaces between Cisco ACI and F5 BIG-IP, F5 ACI ServiceCenter can discover the BIG-IP and add it to the device list as well. F5 ACI Service can also categorize the BIG-IP accordingly, for example, if it is a standalone or in a high availability (HA) cluster. Starting from version 2.11, F5 ACI ServiceCenter supports multi-tenant design too. These are just some of the features and to find out more, check out F5 ACI ServiceCenter User and Deployment Guide.

F5 and Cisco ACI Essentials - Design guide for a Single Pod APIC cluster
Deployment considerations It is usually an easy decision to have BIG-IP as part of your ACI deployment as BIG-IP is a mature feature rich ADC solution. Where time is spent is nailing down the design and the deployment options for the BIG-IP in the environment. Below we will discuss a few of the most commonly asked questions: SNAT or no SNAT There are various options you can use to insert the BIG-IP into the ACI environment. One way is to use the BIG-IP as a gateway for servers or as a routing next hop for routing instances. Another option is to use Source Network Address Translation (SNAT) on the BIG-IP, however with enabling SNAT the visibility into the real source IP address is lost. If preserving the source IP is a requirement then ACI's Policy-Based Redirect (PBR) can be used to make sure the return traffic goes back to the BIG-IP. BIG-IP redundancy F5 BIG-IP can be deployed in different high-availability modes. The two common BIG-IP deployment modes: active-active and active-standby. Various design considerations, such as endpoint movement during fail-overs, MAC masquerade, source MAC-based forwarding, Link Layer Discovery Protocol (LLDP), and IP aging should also be taken into account for each of the deployment modes. Multi-tenancy Multi-tenancy is supported by both Cisco ACI and F5 BIG-IP in different ways. There are a few ways that multi-tenancy constructs on ACI can be mapped to multi-tenancy on BIG-IP. The constructs revolve around tenants, virtual routing and forwarding (VRF), route domains, and partitions. Multi-tenancy can also be based on the BIG-IP form factor (appliance, virtual edition and/or virtual clustered multiprocessor (vCMP)). Tighter integration Once a design option is selected there are questions around what more can be done from an operational or automation perspective now that we have a BIG-IP and ACI deployment? The F5 ACI ServiceCenter is an application developed on the Cisco ACI App Center platform built for exactly that purpose. It is an integration point between the F5 BIG-IP and Cisco ACI. The application provides an APIC administrator a unified way to manage both L2-L3 and L4-L7 infrastructure. Once day-0 activities are performed and BIG-IP is deployed within the ACI fabric using any of the design options selected for your environment, then the F5 ACI ServiceCenter can be used to handle day-1 and day-2 operations. The day-1 and day-2 operations provided by the application are well suited for both new/greenfield and existing/brownfield deployments of BIG-IP and ACI deployments. The integration is loosely coupled, which allows the F5 ACI ServiceCenter to be installed or uninstalled with no disruption to traffic flow, as well as no effect on the F5 BIG-IP and Cisco ACI configuration. Check here to find out more. All of the above topics and more are discussed in detail here in the single pod white paper.F5 & Cisco ACI Essentials - Dynamic pool sizing using the F5 ACI ServiceCenter
APIC EndPoints and EndPoint Groups When dealing with the Cisco ACI environment you may have wondered about using an Application-Centric Design or a Network-Centric Design. Regardless of the strategy, the ultimate goal is to have an accessible and secure application/workload in the ACI environment. An application is comprised of several servers; each one performing a function for the application (web server, DB server, app server etc.). Each of these servers may be physical or virtual and are treated as endpoints on the ACI fabric. Endpoints are devices connected to the network directly or indirectly. They have an address, attributes and can be physical or virtual. Endpoint examples include servers, virtual machines, network-attached storage, or clients on the Internet. An EPG (EndPoint Group) is an object that contains a collection of endpoints, which can be added to an EPG either dynamically or statically. Take a look at the relationship between different objects on the APIC. Click here for more details. Relationship between Endpoints and Pool members If an application is being served by web servers with IPs having address's in the range 192.168.56.*, for example, then these IP addresses will be presented as an endpoint in an endpoint group (EPG) on the APIC. From the perspective of BIG-IP, these web servers are pool members of a particular pool. The F5 ACI ServiceCenter is an application developed on the Cisco ACI App Center platform designed to run on the APIC controller. It has access to both APIC and BIG-IP and can correlate existing information from both devices to provide a mapping as follows: BIG-IP | APIC ________________________________________________________________________ VIP: Pool: Pool Member(s): Route Domain (RD) | Tenant: Application Profile: End Point group: Virtual Routing and Forwarding (VRF) This gives an administrator a view of how the APIC workload is associated with the BIG-IP and what all applications and virtual IP's are tied to a tenant. Click here for more details on this visibility dashboard and learn more on how and under what situations the dashboard can be helpful. In this article we are going to see how the F5 ACI ServiceCenter can take advantage of the endpoints learned by the ACI fabric to dynamically grow/shrink pool members. Dynamic EndPoint Attach and Detach Let's think back to our application which is say being hosted on 100's of servers, these servers could be added to an APIC EPG statically by a network admin or they could be added dynamically through a vCenter or openstack APIC integration. In either case, these endpoints ALSO need to be added to the BIG-IP where the endpoints can be protected by malicious attacks and/or load-balanced. This can be a very tedious task for a APIC or a BIG-IP administrator. Using the dynamic EndPoint attach and detach feature on the F5 ACI ServiceCenter, this burden can be reduced. The application has the ability to adjust the pool members on the BIG-IP based on the server farm on the APIC. On APIC when an endpoint is attached, it is learned by the fabric and added to a particular tenant, application profile and EPG on the APIC. The F5 ACI ServiceCenter provides the capability to map an EPG on the APIC to a pool on the BIG-IP. The application relies on the attach/detach notifications from the APIC to add/delete the BIG-IP pool-members. There are different ways in which the dynamic mapping can be leveraged using the F5 ACI ServiceCenter based on the L4-L7 configuration: Scenario 1: Declare L4-L7 configuration using F5 ACI ServiceCenter Scenario 2: L4-L7 configuration already exists on the BIG-IP Scenario 3: Use dynamic mapping but do not declare the L4-L7 configuration using the F5 ACI ServiceCenter Scenario 4: Use the F5 ACI ServiceCenter API's to define the mapping along with the L4-L7 configuration Let's take a look at each one of them in detail. Scenario 1: Declare L4-L7 configuration using F5 ACI ServiceCenter Let's assume there is no existing configuration on the BIG-IP, a new application needs to be deployed which is front ended by a VIP/Pool/Pool members. The F5 ACI ServiceCenter provides a UI that can be used to deploy the L4-L7 configuration and create a mapping between Pool <-> EPG. There are two options: Basic mode uses FAST and Advanced mode uses AS3. Basic mode: Leverage dynamic endpoint attach and detach feature by using the pre-built Service-Discovery template Advanced mode: Leverage dynamic endpoint attach and detach feature by using Manage Endpoint Mappings Scenario 2: L4-L7 configuration already exists on the BIG-IP If L4-L7 configuration using AS3 already exists on the BIG-IP, the F5 ACI ServiceCenter will detect all partitions and application that in compatible with AS3. Configuration for a particular partition/application on BIG-IP can then be updated to create a Pool <-> EPG mapping. However, there is one condition that is the pool can either have static or dynamic members. Thus, if the pool already has existing members, those members will have to be deleted before a dynamic mapping can be created. To maintain the dynamic mapping, any future changes to the L4-L7 configuration on the BIG-IP should be done via the F5 ACI ServiceCenter. Scenario 3: Use dynamic mapping but do not declare the L4-L7 configuration using the F5 ACI ServiceCenter The F5 ACI ServiceCenter can be used just for the dynamic mapping and pool sizing and not for defining the L4-L7 configuration. For this method, the entire AS3 declaration along with the mapping will be directly send to the BIG-IP using AS3. Since the declaration is AS3, the F5 ACI ServiceCenter will automatically detect a Pool <-> EPG mapping which can be viewable from the inventory tab. Step 1: AS3 declaration with Pool <-> EPG mapping posted directly to the BIG-IP (see below for a sample declaration) Step 2: Sync Endpoints Step 3: View Endpoints Scenario 4: Use the F5 ACI ServiceCenter API's to define the mapping along with the L4-L7 configuration Finally, if the UI is not appealing and automation all the way is the goal, then the F5 ACI ServiceCenter has an API call where the mapping as well as the L4-L7 configuration (which was done in Scenario 1) can be completely automated: URI: https://<apic_controller_ip>>/appcenter/F5Networks/F5ACIServiceCenter/updateas3data.json In this scenario, the declaration is being passed to the F5 ACI ServiceCenter through the APIC controller and NOT directly to the BIG-IP. A sample API call Summary Having knowledge on how AS3 works is essential since it is a declarative API, and using it incorrectly can result in incorrect configuration. Any method mentioned above would work, and the decision on which method to use is based on the operational model that works the best in your environment.

LTM 11.4.1 - Trying to Identify equivalent features to cisco ACE
We have a legacy application which uses the following features in Cisco ACE parameter-map type http PARAMETERS case-insensitive persistence-rebalance set header-maxparse-length 65535 set content-maxparse-length 65535 length-exceed continue parsing non-strict I am looking to find equivalents for these in F5 LTM as once we migrated the application to LTM we see a lot of intermittent issues accessing the application and a lot of 'Resets' from the clients to the Virtual Server IP in tcpdump. The application has multiple pools and we are using the following irule to switch between pools based on a cookie that the application sends to the browser, when CLIENT_ACCEPTED { set default_pool [LB::server pool] } when HTTP_REQUEST { ONECONNECT::reuse disable if { [HTTP::cookie exists "Pool-cookie"] } { switch [HTTP::cookie value "Pool-cookie"] { "Pool1" { pool Pool1 } "Pool2" { pool Pool2 } default { pool $default_pool } } } else { pool $default_pool } } For the persitence-rebalance in ACE we are using Onceconnect, so the LTM can do L7 load-balancing decision for every HTTP request inside the same TCP connection (content switching feature of oneconnect). Just to ensure that the 'server-connection-resuse' is not causing any issues, it has been disabled inside the iRule. Effectively trying to use oneconnect only for the content switching requirement. the http header size has been set tp 65535 in the http_profile. the 'length-exceed continue' option ACE makes it still process the request even if the http header size is more that 65535, but i could not find a similar option to this in LTM. LTM sends a RST if the header size exceeds. Is there any option available in LTM similar to the 'length-exceed continue' feature in ACE??? the 'parsing non-strict' in ACE, ignores malformed cookies in a request and continues parsing the remaining cookies. The application seems to have 'non-compliant RFC2396 characters' in its http responses, which the LTM might not like if it processes only RFC2396 compliant http requests. Is there any feature in LTM similar to the 'parsing non-strict' in ACE so it can continue process other cookies eventhough there are few malformed cookies from the application???How to onboard F5 BIG-IP VE in Cisco CSP 2100/5000 for NFV solutions deployment

To check BIG-IP MAC address, go to "Network" -> "Interfaces" To check on the CSP, click on the service deployed, scroll to the bottom, expand the VNIC information tab Configure VLAN consistent with the CSP 2100 VLAN tag configuration, make sure VLANs are untagged at the BIG-IP level After BIG-IP VE connectivity is established in the network rest of the configurations, such as Self-IP, default gateway, virtual servers are consistent with any BIG-IP VE configuration.
