The table below describes the significant fields in the display.

Table 1 show aaa servers Field Descriptions
Field	Description
id	A unique identifier for all AAA servers defined on the router.
priority	Order of use for servers within a group.
host	IP address of the private RADIUS server host.
auth-port	UDP destination port on the AAA server that is used for authentication and authorization requests. The default value is 1645.
acct-port	UDP destination port on the AAA server that is used for accounting requests. The default value is 1646.
State	Describes the current state of the AAA server; the duration, in seconds, that the server has been in that state; and the duration, in seconds, that the server was in the previous state. The following states are possible: DEAD--Indicates that the server is currently down and, in the case of failovers, this server will be omitted unless it is the last server in the group. duration--Indicates the amount of time the server is assumed to be in the current state, either UP or DEAD. previous duration--Indicates the amount of time the server was considered to be in the previous state. UP--Indicates that the server is currently considered alive and attempts will be made to communicate with it.
Dead	Indicates the number of times that this server has been marked dead, and the cumulative amount of time, in seconds, that it spent in that state.
Authen	Provides information about authentication packets that were sent to and received from the server, and authentication transactions that were successful or that failed. The following information may be reported in this field: request--Number of authentication requests that were sent to the AAA server. timeouts--Number of timeouts (no responses) that were observed when a transmission was sent to this server. Response--Provides statistics about responses that were observed from this server and includes the following reports: unexpected--Number of unexpected responses. A response is considered unexpected when it is received after the timeout period for the packet has expired. This may happen if the link to the server is severely congested, for example. An unexpected response can also be produced when a server generates a response for no apparent reason. server error--Number of server errors. This category is a “catchall” for error packets that do not fall into one of the previous categories. incorrect--Number of incorrect responses. A response is considered incorrect if it is of the wrong format than the one expected by the protocol. This frequently happens when an incorrect server key is configured on the router. time--Time (in milliseconds) taken to respond to an authentication packets. Transaction: These fields provide information about authentication, authorization, and accounting transactions related to the server. A transaction is defined as a request for authentication, authorization, or accounting information that is sent by the AAA module, or by an AAA client (such as PPP) to an AAA protocol (RADIUS or TACACS+), which may involve multiple packet transmissions and retransmissions. Transactions may require packet retransmissions to one or more servers in a single server group, to verify success or failure. Success or failure is reported to AAA by the RADIUS and TACACS+ protocols as follows success--Incremented when a transaction is successful. failure--Incremented when a transaction fails; for example, packet retransmissions to another server in the server group failed or did not succeed. A negative response to an Access-Request, such as Access-Reject, is considered to be a successful transaction.
Author	The fields in this category are similar to those in the Authen: fields. An important difference, however, is that because authorization information is carried in authentication packets for the RADIUS protocol, these fields are not incremented when using RADIUS.
Account	The fields in this category are similar to those in the Authen: fields, but provide accounting transaction and packet statistics.
Elapsed time since counters last cleared	Displays the time in days, hours, and minutes that have passed since the counters were last cleared.

Note

In case of Intelligent Services Gateway (ISG), the estimated outstanding accounting transactions will take some time to become zero. This is because there is a constant churn in the interim accounting requests.

The fields in the output of the show aaa serverscommand are mapped to Simple Network Management Protocol (SNMP) objects in the Cisco AAA-SERVER-MIB and are used in SNMP reporting. The first line of the sample output of the show aaa serverscommand (RADIUS: id 24, priority 1, host 172.31.164.120, auth-port 1645, acct-port 1646) is mapped to the Cisco AAA-SERVER-MIB as follows:

id maps to casIndex
priority maps to casPriority
host maps to casAddress
auth-port maps to casAuthenPort
acct-port maps to casAcctPort

Mapping the following set of objects listed in the Cisco AAA-SERVER-MIB map to fields displayed by the show aaa servers command is more straightforward. For example, the casAuthenRequests field corresponds to the Authen: request portion of the report, casAuthenRequestTimeouts corresponds to the Authen: timeouts portion of the report, and so on.

casAuthenRequests
casAuthenRequestTimeouts
casAuthenUnexpectedResponses
casAuthenServerErrorResponses
casAuthenIncorrectResponses
casAuthenResponseTime
casAuthenTransactionSuccesses
casAuthenTransactionFailures
casAuthorRequests
casAuthorRequestTimeouts
casAuthorUnexpectedResponses
casAuthorServerErrorResponses
casAuthorIncorrectResponses
casAuthorResponseTime
casAuthorTransactionSuccesses
casAuthorTransactionFailures
casAcctRequests
casAcctRequestTimeouts
casAcctUnexpectedResponses

12.2SX	This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.

Usage Guidelines

The show access-lists command is used to display the current ACLs operating in the router. Each access list is flagged using the Compiled indication if it is operating as an accelerated ACL.

The display also shows how many packets have been matched against each entry in the ACLs, enabling the user to monitor the particular packets that have been permitted or denied. This command also indicates whether the access list is running as a compiled access list.

Examples

The following is sample output from the show access-lists command when access list 101 is specified:

Router# show access-lists 101
Extended IP access list 101
    permit tcp host 198.92.32.130 any established (4304 matches) check=5
    permit udp host 198.92.32.130 any eq domain (129 matches)

    permit tcp host 198.92.32.130 host 171.69.2.135 eq smtp (2 matches)
    permit tcp host 198.92.32.130 host 198.92.30.32 eq smtp
    permit tcp host 198.92.32.130 host 171.69.108.33 eq smtp

    deny   ip 172.24.24.0 0.0.1.255 224.0.0.0 15.255.255.255
    deny   ip 192.82.152.0 0.0.0.255 224.0.0.0 15.255.255.255
    deny   ip 192.122.173.0 0.0.0.255 224.0.0.0 15.255.255.255
    deny   ip 192.122.174.0 0.0.0.255 224.0.0.0 15.255.255.255

    deny   ip 192.135.240.0 0.0.7.255 224.0.0.0 15.255.255.255
    deny   ip 192.135.248.0 0.0.3.255 224.0.0.0 15.255.255.255

An access list counter counts how many packets are allowed by each line of the access list. This number is displayed as the number of matches. Check denotes how many times a packet was compared to the access list but did not match.

The following is sample output from the show access-lists command when the Turbo Access Control List (ACL) feature is configured on all of the following access lists.

Note

The permit and deny information displayed by the show access-lists command may not be in the same order as that entered using the access-list command.

Router# show access-lists
Standard IP access list 1 (Compiled)
    deny   any
Standard IP access list 2 (Compiled)
    deny   192.168.0.0, wildcard bits 0.0.0.255
    permit any
Standard IP access list 3 (Compiled)
    deny   0.0.0.0
    deny   192.168.0.1, wildcard bits 0.0.0.255
    permit any
Standard IP access list 4 (Compiled)
    permit 0.0.0.0
    permit 192.168.0.2, wildcard bits 0.0.0.255

The following is sample output from the show access-lists command that shows information for IPv6 access lists when IPv6 is configured on the network:

Router# show access-lists
