SMC88xxM Jumbo Frame
In order to use the Jumbo frame in SMC88xxM, the firmware must be at least v2.2.0.11. Please also use the following sequence to enable the jumbo frame.
The know-how is to set up "Jumbo frame mtu" first, before you enable "Jumbo frame" on global mode.The same setting sequence as per interfaces.
For example, If you want to enable Jumbo frame on Port 1.
Following is the procedure for your reference.
Step 1. Set MTU
Console#
Console#conf
Console(config)#jumbo frame mtu 9216
Step 2. Enable Jumbo Frame
Console(config)#jumbo frame
Step 3. Set MTU on Interface
Console(config)#int eth 1/1
Console(config-if-e1/1)#jumbo frame mtu 9216
Step4. Enable Jumbo Frame
Console(config-if-e1/1)#jumbo frame

SMC289X Turbo Mode
According to RD, in order to use the Turbo mode it must using the high band frequency.
That's why it only can use 5 channels when choosing the turbo mode in 11a frequency.
Besides, if using outdoor antenna in the antenna selection, it will only use 3 channels due to the frequency. Else, if using indoor antenna it will show 5 channels.

PoE Calculation
Below is the formula to calculate the max PoE port that can support by single switch
1. Max power consumption = 225W (For example: SMC6128PL2)
2. Switch consumption = 45W
3. PoE consumption = 180W (225W-45W)
4. PoE standard is 15.4W per port
5. 180W/15.4W = 11.8xx
Thus, the maximum port can support is 11 ports.

How to use MRTG with IIS (Windows Version)
Pre-requisite: MRTG Version 2.16.2, ActivePerl 5.8.8, Window XP Machine with IIS Installed and information of the switch/router
Steps for configuring the MRTG:
1. Download the MRTG from here
2. Download the ActivePerl 5.8.8 from here
3. Install the ActivePerl into the computer
4. Unzip the MRTG files into C:\ (For example: C:\MRTG)
5. Please make sure that the Perl Binary directory is listed in the system path:
C:\Perl\bin;%SystemRoot%\system32;%SystemRoot%;...
6. Go to Run --> Cmd into the Dos Prompt
7. CD\ to the C:\
8. Cd MRTG
9. Cd Bin
10. Command: perl cfgmaker [snmp string]@[ip address of the device] --gloabl "WorkDir: c:\Inetpub\wwwroot\mrtg" --output [filename].cfg
11. To generate the index file: perl indexmaker [filename].cfg > c:\Inetpub\wwwroot\mrtg\index.html
12. Run the mrtg by type in: perl mrtg [filename].cfg
13. You can using the schedule task to run it by every 5 minutes
14. You need to create a batch file like below:
cd\mrtg\bin
perl mrtg [filename].cfg
