Step 7: Configuring Access Control Lists (ACLs)
The SCE 2000 can be configured with Access Control Lists (ACLs), which are used to permit or
deny incoming connections on any of the management interfaces.
Note
ACL #0 is a pre-defined list that permits access to all IP addresses.
Configuration of access control lists is done in two stages:
Step 1 Create the access control lists.
You may create 99 ACLs with a maximum of 20 entries per list. Each entry consists of an IP address, and
an indication of whether access is permitted or denied to this IP address.
Step 2
Assign the ACLs to the appropriate management interface. (See Step 9: Configuring the
Topology-Dependent Parameters.)
The dialog permits you to skip the creation/editing of the ACLs and go directly to assigning ACLs to the
management interfaces.
Entry Formats
Each ACL may permit/deny access to any IP address, one or more ranges of IP addresses, or one
or more individual IP address. Three entry formats are available to support these options:
• Any IP address: Type the word “any”. Any IP address will be permitted or denied access.
• Range of IP addresses: Type the beginning IP address in the desired range, then enter the
wildcard bits that define the range.
This wildcard functions like a reverse mask, in that all “1” bits in the wildcard indicate the
corresponding bit in the IP address should be ignored. All other bits must match the
corresponding bit in the specified IP address. Refer to the table below for examples.
Each range of IP addresses can be configured to be permitted or denied access.
• Individual IP address: Type the desired IP address, then enter the wildcard bits 0.0.0.0.
Each individual IP address can be configured to be permitted or denied access.
