Chapter 1 Configuring File Services
Configuring File Services
Note Certain combinations of operating systems and file systems on a file server can result in the server
responding with different timestamp precision for different SMB commands. In this situation, you may
not get the highest possible CIFS optimization if the CIFS application accelerator avoids using cached
files with mismatched timestamps in favor of preserving data coherency.
Using File Services on the NME-WAE
If you are running WAAS on a network module that is installed in a Cisco access router, there are specific
memory requirements for supporting file services. The NME-WAE must contain at least 1 GB of RAM
to support file services:
If you try to enable file services and the device does not contain enough memory, the WAAS Central
Manager will display an error message.
You can check the amount of memory that a device contains in the Device Dashboard window. For
details, see the “Device Dashboard Window” section on page 1-8.
Configuring File Services
To accelerate CIFS traffic, you can enable and configure either the CIFS or the SMB accelerators, as
described in the following topics:
• Configuring the CIFS Accelerator, page 1-8
• Configuring the SMB Accelerator, page 1-19
Configuring the CIFS Accelerator
The CIFS accelerator relies on automatic discovery and transparently accelerates CIFS traffic with no
configuration needed.

1. With Windows 7 and Vista clients, the CIFS accelerator transparently uses the SMB1 protocol.
2. WAAS supports Novell 6.5 for CIFS optimization, server consolidation, and generic network acceleration for NCP,
eDirectory/NDS, and iPrint. If your Novell file server uses the NFAP option, WAAS can optimize your Novell traffic
at the transport layer as well as at the protocol layer using the WAAS CIFS adapter. NFAP is Novell's Native File Access
Pack that uses the CIFS protocol on top of Novell's NCP (Novell Core Protocol).
