CHAPTER 6: ACCESS CONSIDERATIONS

CONFIGURING PORT SECURITY THROUGH THE COMMAND LINE INTERFACE

MULTILINK ML1600 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL

6–11

Note

It is assumed here that the user is familiar with IP addressing schemes (e.g. class A, B, C,
etc.), subnet masking and masking issues such as how many stations are allowed for a
given subnet mask.

In Example 6-7, any computer on 3.94.245.10 network is allowed (note how the subnet
mask indicates this). Also, a specific station with IP address 3.94.245.25 is allowed (again
note how the subnet mask is used). An older station with IP address 3.94.245.15 is
removed.

Example 6-7: Allowing/blocking specific IP addresses

ML1600#

ML1600(access)##

allow ip=3.94.245.10 mask=255.255.255.0 service=telne
