Configuration Guide
For existing ACL rule, if edit is performed with specified ACL rule number, the rest part
will not be affected. For example:
First configure an ACL rule:
rule 1 deny ip source 1.1.1.1 0
Then edit the ACL rule:
rule 1 deny ip destination 2.2.2.1 0
And then, the ACL rule becomes:
rule 1 deny ip source 1.1.1.1 0 destination 2.2.2.1 0
The following command can be used to delete an advanced ACL rule:
undo rule rule-id [ comment text ] [ source ] [ destination ] [ source-port ]
[ destination-port ] [ icmp-type ] [ dscp ] [ precedence ] [ tos ] [ time-range ]
[ logging ] [ fragment ] [ vpn-instance vpn-instance-name ]
