Appendix 5 - Tuning Parameters for a Large Number of
subnet-ranged Limits, Pools, & Masks
Tuning for a Large Number of subnet-ranged (>=32 subnet ranges)
Connection Limits, Hard Limits, Masks, Pools, and VLANs
The NetEqualizer currently simplifies your configuration set-up by enabling you to enter
Hard Limits, Connection Limits, Masks, and Pools as “subnet ranges” (i.e. HARD x.x.x.x/24
or /16), instead of as individual rules.
In
Software Update 5.4
we added a tuning parameter that offers you further flexibility in
your use of subnet-ranged Connection Limits, Hard Limits, Masks, and Pools. This
parameter is used to increase the number of subnet-ranged definitions possible, from the
default of 32 up to a maximum of 128.
This parameter does not need to be changed if you use a combined <=32 subnet ranges in
total across Pools, Hard Limits, Masks, and Connection Limits.
Note: You also need to consider the number of VLANs that you have set up in your total. If
you have >32 VLANs, or your number of VLANs + subnet-ranged items > 32, you should
set this parameter.
Set_Max_Table_Size Parameter
The tuning parameter,
set_max_table_size
, is used to increase the number of subnet-
range definitions possible, from the default of 32 up to a maximum of 128.
To set this parameter, go to the Maintenance and Reference Menu,
Click on ->
Maintenance
->
[
Run a Command
]
.
Type in:
/sbin/brctl set_max_table_size my XX
Replace "XX" with the number of subnet-ranged entities that you want to support, such as
'/sbin/brctl set_max_table_size my 45' to support 45.
When you save your changes, in order for them to take effect upon your configuration, you
must stop and then restart equalizing.
Click on ->
Maintenance
->
[
Start/Stop
Equalizing
]
->
[
Stop Equalizing
].
Then restart equalizing by
Clicking on ->
[
Start/Stop
Equalizing
]
->
[
Start Equalizing
].
To persist Set_Max_Table_Size upon reboot
From the Maintenance and Reference menu,
Click on ->
Maintenance
->
[
Edit Autostart
File
]
and add the following to the end of the Autostart file:
Type in:
/sbin/brctl set_max_table_size my XX
You also need the following commands ONCE at the end of the Autostart file:
/etc/init.d/arbitrate stop
sleep 10
/etc/init.d/arbitrate start
Note: NetEqualizer can support a maximum of 128 subnet-ranged entities. All subnet-
ranged Connection Hard Masks + Pools + number of VLANs must be
<=128.
As always, the NetEqualizer continues to support an UNLIMITED number of
individual
Connection Limits, Hard Limits, Masks, and Pools (i.e. x.x.x.x/32).
