Is there a formula to determine the optimal number of has entries? I figured that since the number of connections sometimes exceeds 2048, 4096 would be the best choice...
From the command [email protected]http://www.cisco.com/en/US/docs/ios/security/command/reference/sec_i2.html#wp1061151
"You should increase the hash table size when the total number of sessions running through the context-based access control (CBAC) router is approximately twice the current hash size; decrease the hash table size when the total number of sessions is reduced to approximately half the current hash size. Essentially, try to maintain a 1:1 ratio between the number of sessions and the size of the hash table."
Thanks for the info. Notice how the doc contains the word approximately twice in the same sentence
Thanks for the link! That was very helpful.
