What is the reason for the following error "ACL Maximum rule reached" on the C-Series
When trying to add a permit to an ACL on a C3 - the following error is seen: Maximum Rule Reached Message.
C3(su)->router(Config)#access-list 150 permit ip 172.16.0.0 0.0.255.255 126.96.36.199 0.0.0.31
Maximum rule reached.
The SecureStack ACL limitations are:
9 rules per ACL;
100 rules per Stack;
1 Input ACL per Interface.
Although 9 rules per ACL is the officially recognized maximum, you are allowed to configure 10 rules on an ACL, but it then cannot be applied to an interface. It is not allowed to construct an 11-rule ACL.
