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
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
