{
ipv4
}
address/mask length
• Type 2:
match source-address
{
ipv4
}
address/mask length
• Type 3:
match protocol
{

-
max-value
}
• Type 4: Create two class-maps: one with source-port
and another with destination-port:
•
match source-port
{
source-port-value
|
min-value
-
max-value
}
•
match destination-port
{
destination-port-value
|
min-value
-
max-value
}
These are applicable only for TCP and
UDP protocols.
