Q: How to find the Free ace entries on the controller and What is mean by Free ACE entries at the bottom ?
A: Total ACE entries in use = 762
Total free ACE entries = 6918
Free ACE entries at the bottom = 6218
Next ACE entry to use = 1462 (table 1)
(Aruba-7240) #show acl acl-table | include bottom
Free ACE entries at the bottom = 6218
This means that the contiguous ace entries that are free, usually ACE table gets fragmented as and when ACL is created and deleted.We dont need to much worry about this column.
