show security ipsec security-associations

Syntax

show security ipsec security-associations<brief | detail><fpc slot-number><index SA-index-number><kmd-instance (all | kmd-instance-name)><pic slot-number>

Release Information

Command introduced in Release 8.5 of Junos OS; fpc, pic, and kmd-instance options added in Release 9.3 of Junos OS.

Description

Display information about the IPsec security associations (SAs).

Options

none—Display information about all SAs.

brief | detail—(Optional) Display the specified level of output.

fpc slot-number—Specific to SRX Series devices. Display information about existing IPsec SAs in this particular Flexible PIC Concentrator (FPC) slot. This option is used to filter the output.

index SA-index-number—(Optional) Display detailed information about the specified security association identified by index number. To obtain a list of all SAs that includes their index numbers, use the command with no options.

kmd-instance—Specific to SRX Series devices. Display information about existing IPsec SAs in the key management process (daemon) (KMD) identified by the FPC slot-number and PIC slot-number. This option is used to filter the output.

pic slot-number—Specific to SRX Series devices. Display information about existing IPsec SAs in this particular PIC slot. This option is used to filter the output.

Table 123: show security ipsec security-associations

Field Name

Field Description

Total active tunnels

Total number of active IPsec tunnels.

ID

Index number of the SA. You can use this number to get additional information about the SA.

Gateway

IP address of the remote gateway.

Port

If Network Address Translation (NAT-T) is used, this value is 4500. Otherwise it is the standard IKE port, 500.

Algorithm

Cryptography used to secure exchanges between peers during the IKE Phase 2 negotiations includes

  • An authentication algorithm used to authenticate exchanges between the peers. Options are hmac-md5-95, hmac-sha1-96, or ESP.
  • An encryption algorithm used to encrypt data traffic. Options are 3des-cbc, aes-128-cbc, aes-192-cbc, aes-256-cbc, or des-cbc.

SPI

Security parameter index (SPI) identifier. An SA is uniquely identified by an SPI. Each entry includes the name of the VPN, the remote gateway address, the SPIs for each direction, the encryption and authentication algorithms, and keys. The peer gateways each have two SAs, one resulting from each of the two phases of negotiation: Phase 1 and Phase 2.

Life: sec/kb

The lifetime of the SA, after which it expires, expressed either in seconds or kilobytes.

Sta

State has two options, Installed and Not Installed.

  • Installed—The security association is installed in the security association database.
  • Not Installed—The security association is not installed in the security association database.

    For transport mode, the value of State is always Installed.

Mon

The Mon refers to VPN monitoring status. If VPN monitoring is enabled, then this will show U (up) or D (down). A hyphen (-) means VPN monitoring is not enabled for this SA.

vsys or Virtual-system

The root system.

Tunnel index

Numeric identifier of the specific IPsec tunnel for the SA.

Local gateway

Gateway address of the local system.

Remote gateway

Gateway address of the remote system.

Local identity

Identity of the local peer so that its partner destination gateway can communicate with it. The value is specified as an IP address, fully qualified domain name, e-mail address, or distinguished name.

Remote identity

IP address of the destination peer gateway.

DF-bit

State of the don't fragment bit: set or cleared.

Policy-name

Name of the applicable policy.

Location

FPC—Flexible PIC Concentrator (FPC) slot number.

PIC—PIC slot number.

KMD-Instance—The name of the kmd-instance running on the SPU, identified by the FPC slot-number and PIC slot-number. Currently, 4 kmd-instances running on each SPU and any particular IPsec negotiation is carried out by a single kmd-instance.

Direction

Direction of the security association; it can be inbound or outbound.

AUX-SPI

Value of the auxiliary security parameter index.

  • When the value is AH or ESP, AUX-SPI is always 0.
  • When the value is AH+ESP, AUX-SPI is always a positive integer.

Mode

Mode of the security association:

  • transport—Protects host-to-host connections.
  • tunnel—Protects connections between security gateways.

Type

Type of the security association:

  • manual—Security parameters require no negotiation. They are static and are configured by the user.
  • dynamic—Security parameters are negotiated by the IKE protocol. Dynamic security associations are not supported in transport mode.

State

State of the security association:

  • Installed—The security association is installed in the security association database.
  • Not Installed—The security association is not installed in the security association database.

    For transport mode, the value of State is always Installed.

Protocol

Protocol supported.

  • Transport mode supports Encapsulation Security Protocol (ESP) and Authentication Header (AH).
  • Tunnel mode supports ESP and AH
    • Authentication—Type of authentication used.
    • Encryption—Type of encryption used.

Soft lifetime

The soft lifetime informs the IPsec key management system that the SA is about to expire.

Each lifetime of a security association has two display options, hard and soft, one of which must be present for a dynamic security association. This allows the key management system to negotiate a new SA before the hard lifetime expires.

  • Expires in seconds—Number of seconds left until the SA expires.

Hard lifetime

The hard lifetime specifies the lifetime of the SA.

  • Expires in seconds—Number of seconds left until the SA expires.

Lifesize Remaining

The lifesize remaining specifies the usage limits in kilobytes. If there is no lifesize specified, it shows unlimited.

  • Expires in kilobytes—Number of kilobytes left until the SA expires.

Anti-replay service

State of the service that prevents packets from being replayed. It can be Enabled or Disabled.

Replay window size

Configured size of the antireplay service window. It can be 32 or 64 packets. If the replay window size is 0, the antireplay service is disabled.

The antireplay window size protects the receiver against replay attacks by rejecting old or duplicate packets.
