Service set

Name of the service set for which the IPSec security associations are defined. If appropriate, includes the outside service interface VRF name.

All levels

Rule

Name of the rule set applied to the security association.

detail extensive

Term

Name of the IPSec term applied to the security association.

detail extensive

Tunnel index

Numeric identifier of the specific IPSec tunnel for the security association.

detail extensive

Local gateway

Gateway address of the local system.

All levels

Remote gateway

Gateway address of the remote system.

All levels

IPSec inside interface

Name of the logical interface hosting the IPSec tunnels.

All levels

Local identity

Prefix and port number of the local end

All levels

Remote identity

Prefix and port number of the remote end.

All levels

Primary remote gateway

IP address of the configured primary remote peer.

All levels

Backup remote gateway

IP address of the configured backup remote peer.

All levels

State

State of the primary or backup interface: Active, Offline, or Standby. Both ES PICs are initialized to Offline. For primary and backup peers, State can be Active or Standby. If both peers are in a state of Standby, no connection exists yet between the two peers.

All levels

Failover counter

Number of times a PIC switched between primary and backup interfaces, or the number of times the tunnel switched between the primary and remote peers since the software has been activated.

All levels

Direction

Direction of the security association: inbound or outbound.

All levels

SPI

Value of the security parameter index.

All levels

AUX-SPI

Value of the auxiliary security parameter index.

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

All levels

Mode

Mode of the security association:

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

detail extensive

Type

Type of 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.

detail extensive

State

Status of the security association:

• Installed—The security association is installed in the security association database. (For transport mode security associations, the value of State must always be Installed)
• Not installed—The security association is not installed in the security association database.

detail extensive

Protocol

Protocol supported:

• transport mode supports Encapsulation Security Protocol (ESP) or Authentication Header (AH).
• tunnel mode supports ESP or AH+ESP.

All levels

Authentication

Type of authentication used: hmac-md5-96, hmac-sha1-96, or none.

detail extensive

Encryption

Type of encryption algorithm used: can be aes-cbc (128 bits), aes-cbc (192 bits), aes-cbc (256 bits), des-cbc, 3des-cbc, or None.

detail

Soft lifetime

Hard lifetime

Each lifetime of a security association has two display options, hard and soft, one of which must be present for a dynamic security association. The hard lifetime specifies the lifetime of the SA. The soft lifetime, which is derived from the hard lifetime, informs the IPSec key management system that the SA is about to expire. This information allows the key management system to negotiate a new SA before the hard lifetime expires.

• Expires in seconds seconds—Number of seconds left until the security association expires.
• Expires in kilobytes  kilobytes—Number of kilobytes left until the security association expires.

detail extensive

Anti-replay service

State of the service that prevents packets from being replayed: Enabled or Disabled.

detail extensive

Replay window size

Configured size, in packets, of the antireplay service window: 32 or 64. The antireplay window size protects the receiver against replay attacks by rejecting old or duplicate packets. If the replay window size is 0, antireplay service is disabled.
