I'm configuring ACL on CE6855,there are some questions about this.

Q1. In the ACL, settings like implicit deny any are not included by default. Is this correct?

Q2. If source-port or destination-port is not specified on the rule, it is "any". Is this correct?

Q3.When testing by verification, I conducted a confirmation test of Ping communication consistent with the permit rule.However, even with the display acl command, the target rule remained "0 times matched".

Is there a method or command etc. to count? In addition, adding "logging" at the end in ACL rule did not change.

Hello!

Q1: For the control of user access rights (including Telnet, STelnet, FTP, SFTP, HTTP, SNMP), outer Policy, Filter Policy, igmp-snooping ssm-policy, the default ACL action is denied.

For the other service modules, the default ACL action is permit.

Q2: Correct.

Q3: Because these ACL rules are matched in the chip engine, the statistics with the command 'display acl' is 0. When we want to know the statistics, we can configure a traffic policy to run the statistics and then use the command 'display acl hardware statistics' to get this matched statistics value.
