Hello all,

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.

please help me thanks!

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.

Glad to help you! Any further questions, let us know.
