To configure downloadable policies, perform this task:
Command Purpose
Step 1 Switch# configure terminal Enters global configuration mode.
Step 2 Switch(config)# access-list
access-list-number {deny | permit}
source [source-wildcard] [log]
Defines the default port ACL through a source address and wildcard.
The access-list-number is a decimal from 1 to 99 or 1300 to 1999.
Enter deny or permit to specify whether to deny or permit access if
conditions match.
source is the address of the network or host from which the packet is sent,
specified as follows:
• The 32-bit quantity in dotted-decimal format
• The keyword any as an abbreviation for source and source-wildcard
value of 0.0.0.0 255.255.255.255
You do not need a source-wildcard value.
• The keyword host as an abbreviation for source and source-wildcard
of source 0.0.0.0.
(Optional) Applies the source-wildcard wildcard bits to the source.
(Optional) Enters log to cause an informational logging message about the
packet that matches the entry to be sent to the console.
Step 3 Switch(config-if)# interface
interface-id Enters interface configuration mode.
Step 4 Switch(config-if)# ip access-group
{access-list-number | name} in Controls access to the specified interface.
This step is mandatory for a functioning downloaded policy.
Step 5 Switch(config)# exit Returns to global configuration mode.
Step 6 Switch(config)# aaa new-model Enables AAA.
Step 7 Switch(config)# aaa authorization
network default local Sets the authorization method to local. To remove the authorization
method, use the no aaa authorization network default local command.
Step 8 Switch(config)# ip device tracking Enables the IP device tracking table.
To disable the IP device tracking table, use the no ip device tracking
global configuration commands.
Step 9 Switch(config)# ip device tracking
[probe {count count | interval
interval}]
(Optional) Configures these parameters for the IP device tracking table:
• count—Number of times that the switch sends the ARP probe. The
range is 1 to 5. The default is 3.
• interval—Number of seconds that the switch waits for a response
before resending the ARP probe. The range is 30 to 300 seconds. The
default is 30 seconds.
Step 10 Switch(config)# ip device tracking
[probe {delay interval}] (Optional) Configures the optional probe delay parameter for the IP
device tracking table:
• interval—Number of seconds that the switch delays sending an ARP
probe, triggered by link-up and ARP probe generation by the tracked
device. The range is 1 to 120 seconds. The default is 0 seconds.
