Command Manual – ACL
H3C S7500E Series Ethernet Switches
Note that:
You will fail to create or modify a rule if its permit/deny statement is exactly the
same as another rule. In addition, if the ACL match order is set to auto rather than
config, you cannot modify ACL rules.
When defining ACL rules, you need not assign them IDs. The system can
automatically assign rule IDs, starting with 0 and increasing in certain rule
numbering steps. A rule ID thus assigned is greater than the current highest rule
ID. For example, if the rule numbering step is five and the current highest rule ID is
28, the next rule will be numbered 30.
You may use the display acl command to verify rules configured in an ACL. If the
match order for this ACL is auto, rules are displayed in the depth-first order rather
than by rule number.
Note:
For an Ethernet frame header ACL to be referenced by a QoS policy for traffic
classification, the lsap keyword is not supported.
