Tip To ensure a successful configuration of your VPN using the VSPA, read all of the configuration summaries and guidelines before you perform any configuration tasks.


Overview of Monitoring and Accounting for the VSPA

This chapter describes some IPsec features that can be used to monitor and manage the VSPA. These features include:

The IPsec VPN monitoring feature, which provides VPN session monitoring enhancements that will allow you to troubleshoot the VPN and monitor the end-user interface.

The IPsec VPN accounting feature, which enables session accounting records to be generated by indicating when the session starts and when it stops.

The IPsec and IKE MIB support for Cisco VRF-aware IPsec feature, which provides manageability of VPN routing and forwarding- (VRF-) aware IPsec using MIBs.

Monitoring and Managing IPsec VPN Sessions

The IPsec VPN monitoring feature provides VPN session monitoring enhancements that will allow you to troubleshoot the Virtual Private Network (VPN) and monitor the end-user interface. A crypto session is a set of IPsec connections (flows) between two crypto endpoints. If the two crypto endpoints use IKE as the keying protocol, they are IKE peers to each other. Typically, a crypto session consists of one IKE security association (for control traffic) and at least two IPsec security associations (for data traffic, one per each direction). There may be duplicated IKE security associations (SAs) and IPsec SAs or duplicated IKE SAs or IPsec SAs for the same session in the duration of rekeying or because of simultaneous setup requests from both sides.

Session monitoring enhancements include the following:

Ability to specify an Internet Key Exchange (IKE) peer description in the configuration file

Summary listing of crypto session status

Syslog notification for crypto session up or down status

Ability to clear both IKE and IP Security (IPsec) security associations (SAs) using one command-line interface (CLI)

Adding the Description of an IKE Peer

To add the description of an IKE peer to an IPsec VPN session, perform this task beginning in global configuration mode:

 
Command
Purpose

Step 1 

Router(config)# crypto isakmp peer {ip-address ip-address}

Enables an IPsec peer for IKE querying of authentication, authorization, and accounting (AAA) for tunnel attributes in aggressive mode and enters ISAKMP peer configuration mode.

ip-address—IP address of the peer.

Step 2 

Router(config-isakmp-peer)# description description

Adds a description for an IKE peer.

description—Description identifying the peer.

This example shows how to add a description of an IKE peer:

Router(config)# show crypto isakmp peer 10.2.2.9 
Router(config-isakmp-peer)# description connection from site A 

Verifying Peer Descriptions

To verify peer descriptions, enter the show crypto isakmp peer command:

Router# show crypto isakmp peer 

Peer: 10.2.2.9 Port: 500 
Description: connection from site A 
flags: PEER_POLICY 

When the peer at address 10.2.2.9 connects and the session comes up, the syslog status will be shown as follows:

%CRYPTO-5-SESSION_STATUS: Crypto tunnel is UP. Peer 10.2.2.9:500 Description: connection 
from site A Id: ezvpn

Getting a Summary Listing of Crypto Session Status

You can get a list of all the active VPN sessions by entering the show crypto session command. The listing will include the following:

Interface

IKE peer description, if available

IKE SAs that are associated with the peer by which the IPsec SAs are created

IPsec SAs serving the flows of a session

Multiple IKE or IPsec SAs may be established for the same peer, in which case IKE peer descriptions will be repeated with different values for the IKE SAs that are associated with the peer and for the IPsec SAs that are serving the flows of the session.

You can also use the show crypto session detail variant of this command to obtain more detailed information about the sessions.

The following is sample output for the show crypto session command without the detail keyword:

Router# show crypto session 

Crypto session current status 

Interface: FastEthernet0/1 
Session status: UP-ACTIVE 
Peer: 172.0.0.2/500 
IKE SA: local 172.0.0.1/500 remote 172.0.0.2/500 Active 
IPSEC FLOW: permit ip 10.10.10.0/255.255.255.0 10.30.30.0/255.255.255.0 
Active SAs: 2, origin: crypto map

The following is sample output using the show crypto session command with the detail keyword:

Router# show crypto session detail 

Interface: Tunnel0 
Session status: UP-ACTIVE 
Peer: 10.1.1.3 port 500 fvrf: (none) ivrf: (none) 
Desc: this is my peer at 10.1.1.3:500 Green 
Phase1_id: 10.1.1.3 
IKE SA: local 10.1.1.4/500 remote 10.1.1.3/500 Active 
Capabilities:(none) connid:3 lifetime:22:03:24 
IPSEC FLOW: permit 47 host 10.1.1.4 host 10.1.1.3 
Active SAs: 0, origin: crypto map 
Inbound: #pkts dec'ed 0 drop 0 life (KB/Sec) 0/0 
Outbound: #pkts enc'ed 0 drop 0 life (KB/Sec) 0/0 
IPSEC FLOW: permit ip host 10.1.1.4 host 10.1.1.3 
Active SAs: 4, origin: crypto map 
Inbound: #pkts dec'ed 4 drop 0 life (KB/Sec) 4605665/2949 
Outbound: #pkts enc'ed 4 drop 1 life (KB/Sec) 4605665/2949 

Syslog Notification for Crypto Session Up or Down Status

The syslog notification for crypto session up or down status function provides syslog notification every time the crypto session comes up or goes down. To enable syslog logging of the session status, enter the crypto logging session and crypto logging ezvpn commands in configuration mode.

The following is a sample syslog notification showing that a crypto session is up:

%CRYPTO-5-SESSION_STATUS: Crypto session is UP. Peer 10.6.6.1:500 fvrf=name10 ivrf=name20 
Description: SJC24-2-VPN-Gateway Id: 10.5.5.2 

The following is a sample syslog notification showing that a crypto session is down:

%CRYPTO-5-SESSION_STATUS: Crypto session is DOWN. Peer 10.6.6.1:500 fvrf=name10 
ivrf=name20 Description: SJC24-2-VPN-Gateway Id: 10.5.5.2

Clearing a Crypto Session

In previous Cisco IOS software releases, there was no single command to clear both IKE and IPsec security associations (SAs). Instead, you entered the clear crypto isakmp command to clear IKE and the clear crypto ipsec command to clear IPsec. The clear crypto session command allows you to clear both IKE and IPsec with a single command. To clear a specific crypto session or a subset of all the sessions (for example, a single tunnel to one remote site), you must provide session-specific parameters, such as a local or remote IP address, a local or remote port, a front-door VPN routing and forwarding (FVRF) name, or an inside VRF (IVRF) name. Typically, the remote IP address will be used to specify a single tunnel to be deleted.

If a local IP address is provided as a parameter when you enter the clear crypto session command, all the sessions (and their IKE SAs and IPsec SAs) that share the IP address as a local crypto endpoint (IKE local address) will be cleared. If you do not provide a parameter when you enter the clear crypto session command, all IPsec SAs and IKE SAs in the switch will be deleted.

To clear a crypto session, enter the clear crypto session command in privileged EXEC mode from the switch command line. No configuration statements are required in the configuration file to use this command:

Router# clear crypto session

For complete configuration information for IPsec VPN Monitoring, refer to this URL:

http://www.cisco.com/en/US/docs/ios/12_3t/12_3t4/feature/guide/gt_ipsvm.html

For IPsec VPN monitoring configuration examples, see the "IPsec VPN Monitoring Configuration Example" section.

Configuring SPAN Monitoring for the VSPA

You can monitor VSPA port traffic using the local Switched Port Analyzer (SPAN) or remote SPAN (RSPAN). By configuring two SPAN sessions, one on the inside port and one on the outside port, you can monitor clear traffic and encrypted traffic simultaneously.

For detailed information on using SPAN, see the "Configuring Local SPAN, RSPAN, and ERSPAN" chapter of the Catalyst 6500 Release 12.2SXH and Later Software Configuration Guide at this URL:

http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/configuration/guide/span.html


Note Do not configure one VSPA port as a source for more than one SPAN session.


Configuring a SPAN Session

To configure a local SPAN session using a VSPA port as a source, perform this task beginning in global configuration mode:

 
Command
Purpose

Step 1 

Router(config)# monitor session session_number source [interface type slot/subslot/port | vlan vlan_number] rx

Associates the local SPAN source session number with the source port or VLAN and selects the traffic direction to be monitored.

session_number—A user-defined identifying number for the session. Range is 1 to 66.

Step 2 

Router(config)# monitor session session_number destination interface type slot/port

Specifies the destination for local SPAN session traffic.

This example shows how to configure a local SPAN session to capture inbound traffic before decryption from a VSPA in subslot 0 of module 2 and send the captured traffic to port 16 of module 5:

Router(config)# monitor session 1 source interface gi2/0/2 tx 
Router(config)# monitor session 1 destination interface gi5/16 

This example shows how to capture inbound traffic after decryption:

Router(config)# monitor session 1 source interface gi2/0/1 rx 

This example shows how to capture outbound traffic before encryption:

Router(config)# monitor session 1 source interface gi2/0/1 tx 

This example shows how to capture outbound traffic after encryption:

Router(config)# monitor session 1 source interface gi2/0/2 rx 

Configuring IPsec VPN Accounting

The IPsec VPN accounting feature enables session accounting records to be generated by indicating when the session starts and when it stops.

A VPN session is defined as an Internet Key Exchange (IKE) security association (SA) and the one or more SA pairs that are created by the IKE SA. The session starts when the first IP Security (IPsec) pair is created and stops when all IPsec SAs are deleted. If IPsec accounting is configured, after IKE phases are complete, an accounting start record is generated for the session. New accounting records are not generated during a rekeying.

Session-identifying information and session-usage information is passed to the Remote Authentication Dial-In User Service (RADIUS) server by standard RADIUS attributes and vendor-specific attributes (VSAs).

To enable IPsec VPN accounting, perform this task beginning in global configuration mode:

 
Command
Purpose

Step 1 

Router(config)# aaa new-model

Enables periodic interim accounting records to be sent to the accounting server.

Step 2 

Router(config)# aaa authentication login list-name group radius

Sets authentication, authorization, and accounting (AAA) authentication at login using RADIUS servers.

list-name—Character string used to name the list of authentication methods activated when a user logs in.

group radius—Uses the list of all RADIUS servers for authentication.

Step 3 

Router(config)# aaa authorization network list-name group radius

Runs authorization for all network-related service requests, including Serial Line Internet Protocol (SLIP), PPP, PPP Network Control Programs (NCPs), and AppleTalk Remote Access (ARA).

list-name—Character string used to name the list of authorization methods activated when a user logs in.

group radius—Uses the list of all RADIUS servers for authentication.

Step 4 

Router(config)# aaa accounting network list-name start-stop [broadcast] group radius

Enables AAA accounting of network-related requested services for billing or security purposes when you use RADIUS.

list-name—Character string used to name the list of the accounting methods.

start-stop—Sends a start accounting notice at the beginning of a process and a stop accounting notice at the end of a process. The start accounting record is sent in the background. The requested user process begins regardless of whether the start accounting notice was received by the accounting server.

broadcast—(Optional) Enables sending accounting records to multiple AAA servers. Simultaneously sends accounting records to the first server in each group. If the first server is unavailable, failover occurs using the backup servers defined within that group.

group radius—Uses the list of all RADIUS servers for authentication as defined by the aaa group server radius command.

Step 5 

Router(config)# aaa accounting update periodic minutes

(Optional) Sends accounting updates to the accounting server while a session is up.

minutes — Specifies the interval (in number of minutes) at which accounting records are to be sent to the accounting server.

Step 6 

Router(config)# aaa session-id common

Specifies whether the same session ID will be used for each AAA accounting service type within a call or whether a different session ID will be assigned to each accounting service type.

common—Ensures that all session identification (ID) information that is sent out for a given call will be made identical. The default behavior is common.

Step 7 

Router(config)# crypto isakmp profile profile-name

Audits IP security (IPsec) user sessions and enters isakmp-profile configuration mode.

profile-name—Name of the user profile. To associate a user profile with the RADIUS server, the user profile name must be identified.

Step 8 

Router(conf-isa-prof)# vrf ivrf

Associates the on-demand address pool with a Virtual Private Network (VPN) routing and forwarding (VRF) instance name.

ivrf—VRF to which the IPsec tunnel will be mapped.

Step 9 

Router(conf-isa-prof)# match identity group group-name

Matches an identity from a peer in an ISAKMP profile.

group-name—A unity group that matches identification (ID) type ID_KEY_ID. If unity and main mode Rivest, Shamir, and Adelman (RSA) signatures are used, the group-name argument matches the Organizational Unit (OU) field of the Distinguished Name (DN).

Step 10 

Router(conf-isa-prof)# client authentication list list-name

Configures Internet Key Exchange (IKE) extended authentication (XAUTH) in an Internet Security Association and Key Management Protocol (ISAKMP) profile.

list-name—Character string used to name the list of authentication methods activated when a user logs in. The list name must match the list name that was defined during the authentication, authorization, and accounting (AAA) configuration.

Step 11 

Router(conf-isa-prof)# isakmp authorization list list-name

Configures an IKE shared secret and other parameters using the AAA server in an ISAKMP profile. The shared secret and other parameters are generally pushed to the remote peer via mode configuration (MODECFG).

list-name—AAA authorization list used for configuration mode attributes or preshared keys for aggressive mode.

Step 12 

Router(conf-isa-prof)# client configuration address [initiate | respond]

Configures IKE mode configuration (MODECFG) in the ISAKMP profile.

initiate—(Optional) Switch will attempt to set IP addresses for each peer.

respond—(Optional) Switch will accept requests for IP addresses from any requesting peer.

Step 13 

Router(conf-isa-prof)# accounting list-name

Enables AAA accounting services for all peers that connect via this ISAKMP profile.

list-name— Name of a client accounting list.

Step 14 

Router(conf-isa-prof)# exit

Exits isakmp profile configuration mode and returns to global configuration mode.

Step 15 

Router(config)# crypto dynamic-map dynamic-map-name dynamic-seq-num

Creates a dynamic crypto map template and enters the crypto map configuration command mode.

dynamic-map-name—Name of the dynamic crypto map set that should be used as the policy template.

dynamic-seq-num—Sequence number you assign to the dynamic crypto map entry.

Step 16 

Router(config-crypto-map)# set transform-set transform-set-name

Specifies which transform sets can be used with the crypto map template. A transform set defines IPsec security protocols and algorithms. Transform sets and their accepted values are described in the Cisco IOS Security Command Reference.

transform-set-name—Name of the transform set.

Step 17 

Router(config-crypto-map)# set isakmp-profile profile-name

Sets the ISAKMP profile name.

profile-name—Name of the ISAKMP profile.

Step 18 

Router(config-crypto-map)# reverse-route [remote-peer]

Allows routes (IP addresses) to be injected for destinations behind the VPN remote tunnel endpoint and may include a route to the tunnel endpoint itself (using the remote-peer keyword for the crypto map).

remote-peer—(Optional) Routes of public IP addresses and IP security (IPsec) tunnel destination addresses are inserted into the routing table.

Step 19 

Router(config-crypto-map)# exit

Exits crypto map configuration mode and returns to global configuration mode.

Step 20 

Router(config)# crypto map map-name ipsec-isakmp dynamic dynamic-map-name

Creates a crypto profile that provides a template for configuration of dynamically created crypto maps.

map-name—Name that identifies the crypto map set.

dynamic-map-name—Name of the dynamic crypto map set that should be used as the policy template.

Step 21 

Router(config)# radius-server host ip-address [auth-port auth-port-number] [acct-port acct-port-number]

Specifies a RADIUS server host.

ip-address —IP address of the RADIUS server host.

auth-port-number—(Optional) UDP destination port number for authentication requests; the host is not used for authentication if set to 0. If unspecified, the port number defaults to 1645.

acct-port-number—(Optional) UDP destination port number for accounting requests; the host is not used for accounting if set to 0. If unspecified, the port number defaults to 1646.

Step 22 

Router(config)# radius-server key string

Sets the authentication and encryption key for all RADIUS communications between the switch and the RADIUS daemon.

string—The unencrypted (cleartext) shared key.

Step 23 

Router(config)# interface type slot/[subslot]/port

Configures an interface type and enters interface configuration mode.

slot/[subslot]/ port—Number of the slot, subslot (optional), and port to be configured.

Step 24 

Router(config-if)# crypto map map-name

Applies a previously defined crypto map set to an interface.

map-name—Name that identifies the crypto map set.
