NOTE: If both data
and time limits are
configured, an SA will
expire at whichever
comes first, potentially
when Lifetime still
shows time remaining.
Inbound SPI and Outbound SPI- the 32-bit Security
Parameter Index included in an IPsec packet, together with
the destination IP address and IPsec protocol, uniquely
identifies the SA. SPIs are pseudorandomly derived during
IKE transactions.
crypto suite - the cryptographic algorithm suite in
use by the SA
Peer - the remote IPsec peer participating in the SA by IP
address
local - the subnet of local IP addresses defined in the
SPD entry used by the SA (the outbound source subnet
or inbound destination subnet).
remote - the subnet of remote IP addresses defined in
the SPD entry used by the SA (the inbound source
subnet or outbound destination subnet).
Lifetime - the bottom number in the ratio is lifetime
minutes, which is the global SA time limit specified for the
SA. The top number is the remaining time (a countdown
from the global SA lifetime limit), also in minutes. The last
value is the limit on the amount of data an SA can pass
before being deleted, in kilobytes. The default global setting
configures no data limit for SAs as
unlimited KB.
Use the
-counter switch to show the number of IPsec SAs
currently registered.
# show ipsec -sa -counter
99 SAs registered
You can also delete any or all SAs:
# del ipsec-sa -all|-spi
<spi>
To delete a specific SA, first run show ipsec -sa to obtain the
Security Parameter Index (SPI) of the SA.
6.4.1 IPsec ISAKMP Security Associations
You can view the ISAKMP (Internet Security Association and
Key Management Protocol) Security Associations established
between the Mesh Point and its IPsec peers with
show ipsec:
# show ipsec -isakmp-sa

Use the -counter switch to show the number of ISAKMP SAs
currently registered.
