PARAMETERS
These parameters are displayed:
◆ Type – Selects the type of ACLs to show in the Name list.
◆ Name – Shows the names of ACLs matching the selected type.
◆ Action – An ACL can contain any combination of permit or deny rules.
◆ Address Type – Specifies the source IP address. Use “Any” to include
all possible addresses, “Host” to specify a specific host address in the
Address field, or “IP” to specify a range of addresses with the Address
and Subnet Mask fields. (Options: Any, Host, IP; Default: Any)
◆ Source IP Address – Source IP address.
◆ Source Subnet Mask – A subnet mask containing four integers from 0
to 255, each separated by a period. The mask uses 1 bits to indicate
“match” and 0 bits to indicate “ignore.” The mask is bitwise ANDed with
the specified source IP address, and compared with the address for
each IP packet entering the port(s) to which this ACL has been
assigned.
