Smart Session Table Adjustment
Based on research Radware performed, more than 99% of the Alteon platforms in the field use less than 10% of their session table capacity.
Alteon allocates static memory for the entire session table in advance even if Alteon uses only a few thousand entries.
In order to increase Alteon free memory, the session table has been reduced to 50% of its capacity.
The session table will not be changed automatically in the following cases:
The user changes the default value (100%) of the session table.The session table peak is above 35% since the last reboot. Platform | RAM Size | 100% Session Table | 50% Session Table | Free Memory Saving (free memory improvement) * |

The session table size can also be changed manually with the following CLI command:
/c/slb/adv/sesscap
Enter capacity (400 , 200 , 100 , 75 , 50 , 25 , 12) of entries sessions table: <Session table capacity>
