CHAPTER 6: ACCESS CONSIDERATIONS

ACCESS CONSIDERATIONS

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

ML1200# access

ML1200(access)## allow ip=3.94.245.10 mask=255.255.255.0 service=t

Service(s) allowed for specified address

ML1200(access)## allow ip=3.94.245.25 mask=255.255.255.255 service

Service(s) allowed for specified address

ML1200(access)## remove ip=3.94.245.15 mask=255.255.255.255

Access entry removed

ML1200(access)## exit

ML1200# show ip-access
