2023 Cisco and/or its affiliates. In order to verify whether IKEv1 Phase 2 is up on the ASA, enter the show crypto ipsec sa command. endpoint-dns-name is the DNS name of the endpoint of the tunnel interface. An IKEv1 transform set is a combination of security protocols and algorithms that define the way that the ASA protects data. show vpn-sessiondb summary. WebThe following is sample output from the show vpn-sessiondb detail l2l command, showing detailed information about LAN-to-LAN sessions: The command show vpn-sessiondb detail l2l provide details of vpn tunnel up time, Receiving and transfer Data Cisco-ASA# sh vpn-sessiondb l2l Session Type: LAN-to-LAN Connection : 212.25.140.19 Index : 17527 IP If there is some problems they are probably related to some other configurations on the ASAs. During IPSec Security Association (SA) negotiations, the peers must identify a transform set or proposal that is the same for both of the peers. My concern was the output of "sh crypto isakmp sa" was always showing as "QM_idle". Phase 2 = "show crypto ipsec sa". Establish a policy for the supported ISAKMP encryption, authentication Diffie-Hellman, lifetime, and key parameters. Some of the command formats depend on your ASA software level, Hopefully the above information was helpfull, The field with "Connection: x.x.x.x" lists the remote VPN device IP address, The field with "Login Time" lists the time/date when the L2L VPN was formed, The field with "Duration" shows how long the L2L VPN has been up, Rest of the fields give information on the encryption, data transfered etc. The easiest method to synchronize the clocks on all devices is to use NTP. Note:On the ASA, the packet-tracer tool that matches the traffic of interest can be used in order to initiate the IPSec tunnel (such aspacket-tracer input inside tcp 192.168.1.100 12345 192.168.2.200 80 detailedfor example). If peer ID validation is enabled and if IKEv2 platform debugs are enabled on the ASA, these debugs appear: For this issue, either the IP address of the certificate needs to be included in the peercertificate, or peer ID validation needs to be disabled on the ASA. In order to troubleshoot IPSec IKEv1 tunnel negotiation on an IOS router, you can use these debug commands: Note: If the number of VPN tunnels on the IOS is significant, thedebug crypto condition peer ipv4 A.B.C.D should be used before you enable the debugs in order to limit the debug outputs to include only the specified peer. Details on that command usage are here. In order to go to internet both of the above networks have L2L tunnel from their ASA 5505 to ASA 5520. You must assign a crypto map set to each interface through which IPsec traffic flows. Updated device and software under Components Used. The expected output is to see both the inbound and outbound Security Parameter Index (SPI). 01:20 PM Set Up Site-to-Site VPN. NTP synchronizes the timeamong a set of distributed time servers and clients. I am curious how to check isakmp tunnel up time on router the way we can see on firewall. and try other forms of the connection with "show vpn-sessiondb ?" The tool is designed so that it accepts a show tech or show running-config command from either an ASA or IOS router. By default the router has 3600 seconds as lifetime for ipsec and 86400 seconds for IKE. Set Up Tunnel Monitoring. To see details for a particular tunnel, try: show vpn-sessiondb l2l. It's usually useful to narrow down the debug output first with "debug crypto condition peer " and then turn on debugging level 7 for Ipsec and isakmp: debug cry isa 7 (debug crypto ikev1 or ikev2 on 8.4(1) or later). This section describes the commands that you can use on the ASA or IOS in order to verify the details for both Phases 1 and 2. Hopefully the above information Could you please list down the commands to verify the status and in-depth details of each command output ?. Details 1. This document can be used to verify the status of an IPSEC tunnel, validate tunnel monitoring, clear the tunnel, and restore the tunnel. One way is to display it with the specific peer ip. To permit any packets that come from an IPsec tunnel without checking ACLs for the source and destination interfaces, enter the sysopt connection permit-vpn command in global configuration mode. All of the devices used in this document started with a cleared (default) configuration. ASA#show crypto ipsec sa peer [peer IP add] Display the PSK. Then introduce interesting traffic and watch the output for details. If software versions that do not have the fix for Cisco bug ID CSCul48246 are used on the ASA, then the HTTP-URL-based lookup is not negotiated on the ASA, and Cisco IOS software causes the authorization attempt to fail. Please try to use the following commands. I tried Monitoring-->VPN Statistics--> Session--->Filtered By---> IPSec Site-to-site . ASA#show crypto isakmp sa detail | b [peer IP add] Check Phase 2 Tunnel. If the lifetimes are not identical, then the ASA uses a shorter lifetime. show crypto ipsec client ezvpn should show a state of IPSEC ACTIVE; If the VPN tunnel is not up, issue a ping to AD1 sourced from VLAN 10. To permit any packets that come from an IPsec tunnel without checking ACLs for the source and destination interfaces, enter the sysopt connection permit-vpn command in global configuration mode. You might have to use a drop down menu in the actual VPN page to select Site to Site VPN / L2L VPN show you can list the L2L VPN connections possibly active on the ASA. However, when you use certificate authentication, there are certain caveats to keep in mind. This document describes how to set up a site-to-site Internet Key Exchange version 2 (IKEv2) tunnel between a Cisco Adaptive Security Appliance (ASA) and a router that runs Cisco IOS software. Use these resources to familiarize yourself with the community: The display of Helpful votes has changed click to read more! 1. Tip: Refer to the Most Common L2L and Remote Access IPSec VPN Troubleshooting Solutions Cisco document for more information about how to troubleshoot a site-to-site VPN. BGP Attributes - Path Selection algorithm -BGP Attributes influence inbound and outbound traffic policy. In order to verify whether IKEv1 Phase 2 is up on the IOS, enter theshow crypto ipsec sa command. You should see a status of "mm active" for all active tunnels. EDIT: And yes, there is only 1 Active VPN connection when you issued that command on your firewall. This is the destination on the internet to which the router sends probes to determine the Note: The configuration that is described in this section is optional. These are the peers with which an SA can be established. and it remained the same even when I shut down the WAN interafce of the router. Set Up Tunnel Monitoring. Lets look at the ASA configuration using show run crypto ikev2 command. Could you please list down the commands to verify the status and in-depth details of each command output ?. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Please rate helpful and mark correct answers. An ACL for VPN traffic uses the source and destination IP addresses after Network Address Translation (NAT). The tool is designed so that it accepts a show tech or show running-config command from either an ASA or IOS router. In order to specify the transform sets that can be used with the crypto map entry, enter the, The traffic that should be protected must be defined. For more information, refer to the Information About Resource Management section of the CLI Book 1: Cisco ASA Series General Operations CLI Configuration Guide, 9.8. Data is transmitted securely using the IPSec SAs. In order to configure the Internet Security Association and Key Management Protocol (ISAKMP) policies for the IKEv1 connections, enter the crypto ikev1 policy command: Note:An IKEv1 policy match exists when both of the policies from the two peers contain the same authentication, encryption, hash, and Diffie-Hellman parameter values. And ASA-1 is verifying the operational of status of the Tunnel by Refer to the Certificate to ISAKMP Profile Mapping section of the Internet Key Exchange for IPsec VPNs Configuration Guide, Cisco IOS XE Release 3S Cisco document for information about how to set this up. Thank you in advance. The first thing to validate is that the route for the remote network is correct and pointing to the crypto map interface (typically the outside interface). You can naturally also use ASDM to check the Monitoring section and from there the VPN section. In order to apply this, enter the crypto map interface configuration command: Here is the final IOS router CLI configuration: Before you verify whether the tunnel is up and that it passes the traffic, you must ensure that the traffic of interest is sent towards either the ASA or the IOS router. - edited Regards, Nitin This synchronization allows events to be correlated when system logs are created and when other time-specific events occur. The good thing is that it seems to be working as I can ping the other end (router B) LAN's interface using the source as LAN interface of this router (router A). If your network is live, ensure that you understand the potential impact of any command. In General show running-config command hide encrypted keys and parameters. You might have to use a drop down menu in the actual VPN page to select Site to Site VPN / L2L VPN show you can list the L2L VPN connections possibly active on the ASA. Alternatively, you can make use of the commandshow vpn-sessiondbtoverify the details for both Phases 1 and 2, together. Note:On the ASA, the packet-tracer tool that matches the traffic of interest can be used in order to initiate the IPSec tunnel (such as packet-tracer input inside tcp 10.10.10.10 12345 10.20.10.10 80 detailed for example).

The first thing to validate is that the route for the remote network is correct and pointing to the crypto map interface (typically the outside interface). Please try to use the following commands. I suppose that when I type the commandsh cry sess remote , detailed "uptime" means that the tunnel is established that period of time and there were no downs. You can naturally also use ASDM to check the Monitoring section and from there the VPN section. In order to do this, when you define the trustpoint under the crypto map add the chain keyword as shown here: crypto map outside-map 1 set trustpoint ios-ca chain. The identity NAT rule simply translates an address to the same address. Note: Refer to Important Information on Debug Commands before you use debug commands. Similarly, by default the ASA selects the local ID automatically so, when cert auth is used, it sends the Distinguished Name (DN) as the identity. Check Phase 1 Tunnel. If this is not done, then the the tunnel only gets negotiated as long as the ASA is the responder. One way is to display it with the specific peer ip. If there are multiple VPN tunnels on the ASA, it is recommended to use conditional debugs (. private subnet behind the strongSwan, expressed as network/netmask. 11-01-2017 Phase 1 = "show crypto isakmp sa" or "show crypto ikev1 sa" or "show crypto ikev2 sa". You should see a status of "mm active" for all active tunnels. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. Common places are/var/log/daemon, /var/log/syslog, or /var/log/messages. The expected output is to see both the inbound and outbound Security Parameter Index (SPI). If you change the debug level, the verbosity of the debugs canincrease. This document describes common Cisco ASA commands used to troubleshoot IPsec issue. Configure tracker under the system block. VPNs. View the Status of the Tunnels. Check Phase 1 Tunnel. Is there any other command that I am missing??". ASA-1 and ASA-2 are establishing IPSCE Tunnel.

Some of the command formats depend on your ASA software level. In order to automatically verify whether the IPSec LAN-to-LAN configuration between the ASA and IOS is valid, you can use the IPSec LAN-to-LAN Checker tool. In other words, have you configure the other ASA to tunnel all traffic through the L2L VPN? However, I wanted to know what was the appropriate "Sh" commands i coud use to confirm the same. In your case the above output would mean that L2L VPN type connection has been formed 3 times since the last reboot or clearing of these statistics. Ex. To check if phase 2 ipsec tunnel is up: GUI: Navigate to Network->IPSec Tunnels GREEN indicates up RED indicates down. Is there any similiar command such as "show vpn-sessiondb l2l" on the router? Assigning the crypto map set to an interface instructs the ASA to evaluate all the traffic against the crypto map set and to use the specified policy during connection or SA negotiation. New here? To check if phase 2 ipsec tunnel is up: GUI: Navigate to Network->IPSec Tunnels GREEN indicates up RED indicates down. show vpn-sessiondb summary. Network 1 and 2 are at different locations in same site. At that stage, after retransmitting packets and then we will flush the phase I and the Phase II. Both peers authenticate each other with a Pre-shared-key (PSK). the "QM_idle", will remain idle for until security association expires, after which it will go to "deleted state". Set Up Site-to-Site VPN. If the traffic passes through the tunnel, you must see the encaps/decaps counters increment. In order to troubleshoot IPSec IKEv1 tunnel negotiation on an ASA firewall, you can use these debug commands: Note: If the number of VPN tunnels on the ASA is significant, thedebug crypto condition peer A.B.C.D command should be used before you enable the debugs in order to limit the debug outputs to include only the specified peer.
