show nac-policy through show ospf virtual-links Commands

show nac-policy

To show the NAC policy usage statistics and the assignment of NAC policies to group policies, use the show nac-policy command in privileged EXEC mode.

show nac-policy [ nac-policy-name ]

 
Syntax Description

nac-policy-name

(Optional) Name of the NAC policy for which to display usage statistics.

 
Defaults

If you do not specify a name, the CLI lists all NAC policy names along with their respective statistics.

 
Command Modes

This command was added.

Examples

The following example shows the data for the NAC policies named framework1 and framework2:

ciscoasa(config)# show nac-policy
nac-policy framework1 nac-framework
applied session count = 0
applied group-policy count = 2
group-policy list: GroupPolicy2 GroupPolicy1
nac-policy framework2 nac-framework is not in use.
 

The first line of each NAC policy indicates its name and type (nac-framework). The CLI shows the text “is not in use” next to the policy type if the policy is not assigned to any group policies. Otherwise, the CLI displays the usage data for the group policy. Table 10-1 explains the fields in the show nac-policy command.

 

Table 10-1 show nac-policy Command Fields
Field
Description

applied session count

Cumulative number of VPN sessions to which this ASA applied the NAC policy.

applied group-policy count

Cumulative number of group polices to which this ASA applied the NAC policy.

group-policy list

List of group policies to which this NAC policy is assigned. In this case, the usage of a group policy does not determine whether it appears in this list; if the NAC policy is assigned to a group policy in the running configuration, then the group policy appears in this list.

 
Related Commands

clear nac-policy

Resets the NAC policy usage statistics.

show vpn-session.db

Displays information about VPN sessions, including NAC results.

show vpn-session_summary.db

Displays the number IPSec, Cisco WebVPN, and NAC sessions.

show nameif

To view the interface name set using the nameif command, use the show nameif command in privileged EXEC mode.

show nameif [ physical_interface [. subinterface ] | mapped_name | zone ]

 
Syntax Description

mapped_name

(Optional) In multiple context mode, identifies the mapped name if it was assigned using the allocate-interface command.

physical_interface

(Optional) Identifies the interface ID, such as gigabit ethernet0/1. See the interface command for accepted values.

subinterface

(Optional) Identifies an integer between 1 and 4294967293 designating a logical subinterface.

zone

(Optional) Shows the zone names.

 
Defaults

If you do not specify an interface, the ASA shows all interface names.

Usage Guidelines

In multiple context mode, if you mapped the interface ID in the allocate-interface command, you can only specify the mapped name in a context. The output for this command shows only the mapped name in the Interface column.

Examples

The following is sample output from the show nameif command:

ciscoasa# show nameif
Interface Name Security
GigabitEthernet0/0 outside 0
GigabitEthernet0/1 inside 100
GigabitEthernet0/2 test2 50
 

See the following output for the show nameif zone command:

ciscoasa# show nameif zone
Interface Name zone-name Security
GigabitEthernet0/0 inside-1 inside-zone 100
GigabitEthernet0/1.21 inside inside-zone 100
GigabitEthernet0/1.31 4 0
GigabitEthernet0/2 outside outside-zone 0
Management0/0 lan 0

Command
Description

clear nat counters

Clears NAT policy counters.

nat

Identifies addresses on one interface that are translated to mapped addresses on another interface.

show nat

Displays runtime representation of the NAT policies.

show nat pool

To display statistics of NAT pool usage, use the show nat pool command in privileged EXEC mode.

show nat pool [ cluster ]

Modification

8.3(1)

This command was added.

8.4(3)

The output was modified to show the destination address for extended PAT. The PAT range was also modified depending on the use of the flat and include-reserve keywords.

9.0(1)

Support for IPv6 traffic and the cluster keyword to show the current assignment of a PAT address to the owner unit and backup unit were added.

 
Usage Guidelines

A NAT pool is created for each mapped protocol/IP address/port range, where the port ranges are 1-511, 512-1023, and 1024-65535 by default. If you use the flat keyword for a PAT pool in the nat command, you will see fewer, larger ranges.

Each NAT pool exists for at least 10 minutes after the last usage. The 10 minute hold-down timer is canceled if you clear the translations with clear xlate.

Examples

The following is sample output for the NAT pools created by a dynamic PAT rule shown by the show running-config object network command.

ciscoasa(config)# show running-config object network
object network myhost
host 10.10.10.10
nat (pppoe2,inside) dynamic 10.76.11.25
 
ciscoasa# show nat pool
TCP inside, address 10.76.11.25, range 1-511, allocated 0
TCP inside, address 10.76.11.25, range 512-1023, allocated 0
TCP inside, address 10.76.11.25, range 1024-65535, allocated 1
 

The following is sample output from the show nat pool command showing use of the PAT pool flat option. Without the include-reserve keyword, two ranges are shown; the lower range is used when a source port below 1024 is mapped to the same port.

ciscoasa# show nat pool
 
ICMP PAT pool dynamic-pat, address 172.16.2.200, range 1-65535, allocated 2
TCP PAT pool dynamic-pat, address 172.16.2.200, range 1-1024, allocated 0
TCP PAT pool dynamic-pat, address 172.16.2.200, range 1024-65535, allocated 2
UDP PAT pool dynamic-pat, address 172.16.2.200, range 1-1024, allocated 0
UDP PAT pool dynamic-pat, address 172.16.2.200, range 1024-65535, allocated 2
 

The following is sample output from the show nat pool command showing use of the PAT pool flat include-reserve options.

ciscoasa# show nat pool
 
ICMP PAT pool dynamic-pat, address 172.16.2.200, range 1-65535, allocated 2
TCP PAT pool dynamic-pat, address 172.16.2.200, range 1-65535, allocated 2
UDP PAT pool dynamic-pat, address 172.16.2.200, range 1-65535, allocated 2
 

The following is sample output from the show nat pool command showing use of the PAT pool extended flat include-reserve options. The important items are the parenthetical addresses. These are the destination addresses used to extend PAT.

ICMP PAT pool dynamic-pat, address 172.16.2.200, range 1-65535, allocated 0
ICMP PAT pool dynamic-pat, address 172.16.2.200(172.16.2.99), range 1-65535, allocated 2
