Now I am testing WAE in my lab with the following environment.
Windows 2003 Server
Cisco 2821 with NME-WAE-502-K9 as WAE Core
NIST Net WAN Emulation Software
Cisco 2821 with NME-WAE-502-K9 as WAE Edge
enabled CEF, WCCP v2 with TCP promiscuous mode service (WCCP services 61 and 62)
enabled WCCP v2
NIST Net parameters:
Packet loss: 0.5%
Test Tools/Methods on PC:
Cisco WAFS Benchmark Tool for Microsoft Office Application downloaded from CCO
for CIFS/SMB application
TCP Replay utility downloaded from CCO for HTTP application
FTP for FTP application
In this environment, I can get good result for HTTP (by using TCP Reply utility) and FTP, that is,
speed for downloading file by HTTP and FTP is improved over WAN (NIST Net).
However I can not see the effectiveness of WAE for CIFS/SMB traffic by using WAFS Benchmark Tool.
I do not configure WAFS (Wide Area File Services), because I can not configure it due to lack of
DRAM on WAE Core.
2GB DRAM is needed to get WAE Core to be worked as WAFS core cluster but both WAE have
just 1GB DRAM.
So I am testing how WAE efficiently work for WAFS Benchmark Tool without WAFS.
However the result of testing is not indicating WAE efficiency for WAFS Benchmark Tool.
That is, Speed is not different, in other words Speed does not change so much in the following
Remove WCCP v2 configuration from Cisco 2821
Then PC accesses Windows 2003 server by using WAFS Benchmark Tool
Enable WCCP v2 with TCP promiscuous mode service (WCCP services 61 and 62) on Cisco
2821 and WAE and restart WAE to clear any cache information
Then PC accesses Windows 2003 server (it is a first time) by using WAFS Benchmark Tool
In the case of PC has been accesses Windows server in the past
PC accesses Windows 2003 server (it is a second time) by using WAFS Benchmark Tool
And unfortunately, when "wccp cifs-cache" command is configured or not on both WAE,
the result is the same, that is, Speed does not change so much.
I am confusing about optimization for CIFS/SMB traffic.
According to "Default Application Policies" in the Cisco Wide Area Application
Services Configuration Guide,
WAAS, by default, handles CIFS/SMB traffic with LZ, TFO and DRE.
WAAS Action: LZ+TFO+DRE
Destination Ports: 139, 445
So I was thinking WAE optimize CIFS/SMB traffic even if no WAFS configured...
Do I need to configure WAFS in other words WAFS must be configured to achieve
the effect of WAE for CIFS/SMB traffic ?
Do I need to configure additional command to get WAE work fine for CIFS/SMB traffic
without WAFS ?
Is my idea wrong ? that is, WAFS Benchmark Tool is not appropriate tool in this
environment (no WAFS) ?
Your assistance would be appreciated.
Configs are good and with F's you have an optimized session. So, you should be getting good optimization. Do a clear dre cache and answer yes. Then reboot the PC and restart the connection to the server. Instead of using the benchmark tool, try to cut & paste from the server. After the first cut & paste, issue a show dre statistic dre and make sure the DRE is not zero percentage. Is this really a server or is it just a PC that is sharing a drive?
