Chapter 5 Connecting the Management Interfaces and Performing Initial System Configuration

Initial System Configuration

Step 6 If you entered a specific IP address, enter the wildcard bits to define a range of IP addresses and press Enter. (See Entry Formats (on page 5-12).)

To define an individual IP address, type 0.0.0.0 and press Enter. There is no default for this parameter.

Enter wildcard bits:

Step 7 The maximum number of entries in an ACL is 20.

If the “any” option was used, no other IP addresses may be added to the list.

•To add more entries, type y and press Enter

Would you like to add another entry to this list? [no]:y

Enter up to 20 entries as described in step 5 and step 6.

•When all entries have been added, press Enter

Would you like to add another entry to this list? [no]:

Step 8 When all entries are added to one list, you are asked whether you would like to create another ACL. You may define up to 99 ACLs.

•To create another ACL, type y and press Enter

Would you like to configure another list? [no]: y

Enter up to 20 IP addresses in this new ACL, as described in step 5 and step 6.

•When all ACLs have been created, press Enter.

Would you like to configure another list? [no]:

You are now prompted to assign the desired ACLs to restrict IP and Telnet access. Step 9 Restrict IP access to the SCE 1000 by assigning the appropriate ACL.

Type the number of the ACL to be assigned to IP access and press Enter. To accept the default ACL, press Enter.

Enter IP access-class [0]:

Step 10 Restrict Telnet access to the SCE 1000 by assigning the appropriate ACL.

Type the number of the ACL to be assigned to the Telnet interface and press Enter.

To accept the default ACL, press Enter. Enter Telnet access-class [0]: 2

EXAMPLE:

This example illustrates a common access control scenario. Let us assume the following:

•We want to permit every station to access the SCE on the management port (e.g. ping, SNMP polling etc.).

•We want to restrict Telnet access to only a few permitted stations.

We therefore need to create two access control lists:

•For general IP access — permit access to all IP addresses.

•For Telnet — permit access to the specified IP address, and deny to all others.
