WAAS Express is NOT part of Cisco IWAN. PfR and WAAS Express do not interoperate. As Finn suggested you should use the ISR-4K with ISR-WAAS if you want a full integrated solution. Or install an UCS-E and vWAAS. Reach out to your Cisco account team and I'm sure they could help you come up with a proper BoM / design.

Your understanding is correct. Also in WAAS 5.x this is the default configuration l2-redirect, l2-return, egress-method l2, mask assignment.

No this is not possible. WAAS policy engine does not intercept non-TCP traffic. Hence you can not classify / report on it.

Jan, There is a bug with the Google Chrome and the Google plugin but this has been worked around / fixed in WAAS 5.3.3 http://www.cisco.com/en/US/docs/app_ntwk_services/waas/waas/v533/ws533xrn.html#wp216145 CSCui82284 CM page loading issues in Chrome browser version- 29 If you can't upgrade then try using Firefox.

WAAS does not perform any actions on non-TCP traffic. If you are trying to apply some DSCP marking I'd suggest doing this on the switch or router before / after the WAAS device.

When you do prepositioning the Branch WAE acts as the client and goes direct to the server. As such the Branch WAE IP must be allowed through your Firewall, AND it must get redirected to the Core WAAS accelerator. Thus, if you are using WCCP to redirect to the Core WAAS device and if you're using a redirect list, make sure to permit the IP of the WAE. Also you'll want to make sure the server you are trying to preposition from does not have any security restrictions that would prevent the WAE from browsing the directories / copying the files. Hints to the problem could be found in the errorlog/cifsao-errorlog.current file. I'd suggest opening a TAC case if the above does not help.

A central manager is required to managed all of your accelerators properly / be in a supported configuration. You don't necessarily need a physical appliance though. We do have a virtual form factor (vWAAS and vCM) that can run on a ESXi hypervisor. vWAAS is the accelerator version and vCM is the manager version. http://www.cisco.com/en/US/docs/app_ntwk_services/waas/waas/vwaas/guide/vwaasguide.html#wp69212

WCCP router 10.10.10.10 unusable for service id: 62 reason: Assignment method mismatch with router That indicates your WAAS device is sending an assignment method (probably HASH) that is not supported by this 4500. In the 4500 scenario WAAS must be L2 adjacent, and configured for L2-redirect and MASK assignment, and L2-return (if your version of WAAS supports it). http://www.cisco.com/en/US/partner/docs/switches/lan/catalyst4500/12.2/15.02SG/configuration/guide/wccp.html#wp1000978 I'm not sure what version of WAAS you are running. If running WAAS 5.x your config will look like this (since the defaults are l2-redirct, mask, and l2 return). wccp router-list 1 10.10.10.10 wccp tcp-promiscuous service-pair 61 62 router-list-num 1 enable exit http://www.cisco.com/en/US/docs/app_ntwk_services/waas/waas/v531/command/reference/glob_cfg.html#wp2067854 If running WAAS 4.x your config will look like this: wccp version 2 wccp router-list 1 10.10.10.10 wccp tcp-promiscuous service-pair 61 62 failure-detection 30 wccp tcp-promiscuous service-pair 61 62 router-list-num 1 wccp tcp-promiscuous service-pari 61 62 l2-redirect mask-assign l2-return http://www.cisco.com/en/US/docs/app_ntwk_services/waas/waas/v441/command/reference/glob_cfg.html#wp2067854

Are you referring to WCCP for WAAS? If so you are correct two service groups are defined one which hashes on source ip and the other hashes on destination ip. The default WAAS config for WAAS would be: wccp router-list 1 14.110.3.129 wccp tcp-promiscuous service-pair 61 62 router-list-num 1 enable exit ! This means you have to globally define 61 and 62 on your router and then specific which interfaces you want to redirect on and in which direction: pdi-2821-rtp#sh run Building configuration... ! hostname pdi-2821-rtp ! ip wccp 61 ip wccp 62 ! ! interface GigabitEthernet0/0.1 description Client-LAN encapsulation dot1Q 500 ip address 14.110.3.113 255.255.255.240 ip wccp 61 redirect in ip flow ingress ! interface GigabitEthernet0/0.2 description WAVE-574 encapsulation dot1Q 600 ip address 14.110.3.129 255.255.255.240 ip helper-address 10.86.77.7 ip flow ingress ! interface GigabitEthernet0/1 description WAN Link ip address 14.110.3.62 255.255.255.252 ip wccp 62 redirect in ip flow ingress ip flow egress duplex full speed auto Note, that WCCP services for WAAS are TCP only (see keyword tcp-promiscuous). When WCCP services are negotiated between the router and WAAS device it signals that it's interersted in TCP packets only (all TCP packets). Thus, UDP traffic will never be redirected to WAAS (and you would not want to since it does not optimize UDP). You can also configure any service-pair numbers if 61/ 62 happen to be in use by another WCCP service. For example: wccp router-list 1 14.110.3.129 wccp tcp-promiscuous service-pair 41 42 router-list-num 1 enable exit ! Just then make sure you configure this service pair and redirect interfaces appropriately on your WCCP router (14.110.3.129 in this case).

Tammy, What is preventing you from configuing WAAS on SRE with L2 WCCP / Mask assignment via the internal interface? This is totally feasible. If you are trying to decrease CPU utilization on your router, don't expect switching from GRE to L2 to make a drastic difference. The ISR G2 is a software based platform, as such WCCP (whether L2 or GRE) is processed by the CPU with CEF assistance. True removing the GRE encapsulation will save some processing overhead, but in the end it's the PPS (packets per second) your router is handling that's driving the CPU. Remember when you add WCCP / WAAS to the flow it's no longer packet in/ packet out on the router. Compressed data in on WAN, out to WAAS, uncompressed from WAAS back to Router, out on the LAN, then the reverse... uncompressed data on the LAN in to the router, out to WAAS, compressed from WAAS out to the router, then out on the WAN. So depending on the compression observed you will see > 2x the amount of traffic being processed by the router.

In the context of WAAS using WCCP services 61 and 62... Generally speaking at the branch 61 is placed on the LAN and 62 is placed on the WAN facing interfaces. In the Core / DC it is reversed 62 on LAN and 61 on the WAN. 61 hashes on source IP and 62 hashes on destination. Hence in typical branch to DC / hub and spoke type deployments this is the most common placement of WCCP services. Both are redirect in statements as well (e.g. ip wccp 61 redirect in). Now, you may have other WCCP services or a specific configuration reason to use redirect out (e.g. maybe you have DMVPN deployment). For a good guide see this validated design document: http://www.cisco.com/en/US/docs/solutions/SBA/February2013/Cisco_SBA_BN_ApplicationOptimizationDeploymentGuide-Feb2013.pdf

Both 694-16G and 24G versions are targeted to the 200Mbps WAN link. However, there is nothing in the system to limit this, and this WAN BW number serves as a guideline. Cisco WAAS devices are not limited to a specific WAN link capacity by a license. The numbers specified are based on average typical load assumptions. Limitations are based on static system resource limitations and dynamic load factors. Dynamic load factors are based on specific use case scenarios; therefore capacity may be higher or lower depending on actual use. Additionally, Cisco WAAS will continue to optimize connections up to the rated connection capacity. Beyond this capacity, existing active connections will continue to be optimized, and new connections will be handled as pass-through with no optimization until the load applied to the device falls below the rated capacity.
