Remarks
3.
(Optional.) Configure a
description for the IPsec
profile.
description
text
By default, no description is
configured.
4.
Reference an IPsec
transform set for the IPsec
profile.
transform-set
transform-set-name
By default, no IPsec transform set is
referenced for an IPsec profile.
The referenced IPsec transform set
must use the transport mode.
5.
Configure an SPI for an
SA.
sa
spi
{
inbound
|
outbound
} {
ah
|
esp
}
spi-number
By default, no SPI is configured for
an SA.
6.
Configure keys for the
IPsec SA.
•
Configure an authentication key in
hexadecimal format for AH:
sa hex-key authentication
{
inbound
|
outbound
}
ah
{
cipher
|
simple
}
key-value
•
Configure an authentication key in
character format for AH:
sa string-key
{
inbound
|
outbound
}
ah
{
cipher
|
simple
}
key-value
•
Configure a key in character
format for ESP:
sa
string-key
{
inbound
|
outbound
}
esp
[
cipher
|
simple
]
key-value
•
Configure an authentication key in
hexadecimal format for ESP:
sa hex-key authentication
{
inbound
|
outbound
}
esp
{
cipher
|
simple
}
key-value
•
Configure an encryption key in
hexadecimal format for ESP:
sa hex-key encryption
{
inbound
|
outbound
}
esp
{
cipher
|
simple
}
key-value
By default, no keys are configured
for the IPsec SA.
Configure a key for the security
protocol (AH, ESP, or both) you
have specified.
If you configure a key in character
format for ESP, the device
automatically generates an
authentication key and an
encryption key for ESP.
If you configure a key in both the
character and hexadecimal
formats, only the most recent
configuration takes effect.
Configuring SNMP notifications for IPsec
After you enable SNMP notifications for IPsec, the IPsec module notifies the NMS of important module
events. The notifications are sent to the device's SNMP module. You can configure the notification
transmission parameters for the SNMP module to specify how the SNMP module displays notifications.
For more information about SNMP notifications, see
Network Management and Monitoring
Configuration Guide
.
To generate and output SNMP notifications for a specific IPsec failure or event type, perform the following
tasks:
1.
Enable SNMP notifications for IPsec globally.
2.
Enable SNMP notifications for the failure or event type.
