pattern with source/destination IP address or MAC address, use the following command.
Command
Mode
Description
ip
{
A.B.C.D
|
A.B.C.D/M
|
any
}
{
A.B.C.D
|
A.B.C.D/M
|
any
} [<0-
255>]
Flow
Classifies an IP address.
A.B.C.D: source/destination IP address
A.B.C.D/M: source/destination IP address with mask
any: any source/destination IP address
0-255: IP protocol number
ip
{
A.B.C.D
