See Global Service Command Reference for information on encryption key groups for an SDP and VPRN Services Command Reference for information on encryption key groups for a VPRN service.
Refer to the “IP Router Command Reference” section in the 7705 SAR Router Configuration Guide for information on router interface encryption commands.
Refer to the “Configuration Command Reference” section in the 7705 SAR Interface Configuration Guide for information on Ethernet port encryption commands.
This command is used to add a description to the key group being referenced.
The no form of the command reverts to the default value.
n/a
This command enables the context to configure group encryption parameters.
This command is used to create a key group. Once the key group is created, use the command to enter the key group context or delete a key group.
The no form of the command removes the key group. Before using the no form, the key group association must be deleted from all services that are using this key group.
n/a
This command specifies the Security Association, referenced by the Security Parameter Index (SPI), to use when performing encryption and authentication on NGE packets egressing the node for all services configured using this key group.
The no form of the command returns the parameter to its default value and is the same as removing this key group from all outbound direction key groups in all services configured with this key group (that is, all packets of services using this key group will egress the node in without being encrypted).
n/a
This command specifies the hashing algorithm used to perform authentication on the Encapsulating Security Payload (ESP) within NGE packets for services configured using this key group. All SPI entries must be deleted before the no form of the command may be entered or the esp-auth-algorithm value changed from its current value.
The no form of the command reverts to the default value.
sha256
This command specifies the encryption algorithm used to perform encryption on the Encapsulating Security Payload (ESP) within NGE packets for services configured using this key group. All SPI entries must be deleted before the no form of the command may be entered or the esp-encryption-algorithm value changed from its current value.
The no form of the command resets the parameter to the default value.
aes128
This command is used to name the key group. The key group name can be used to reference a key group when configuring services or displaying information.
The no form of the command reverts to the default value.
n/a
This command is used to create a security association for a specific SPI value in a key group. The command is also used to enter the authentication and encryption key values for the security association, or to delete a security association.
The SPI value used for the security association is a node-wide unique value, meaning that no two security associations in any key group on the node may share the same SPI value.
Keys are entered in clear text. Once configured, they are never displayed in their original, clear text form. Keys are displayed in a 7705 SAR-encrypted form, which is indicated by the system-appended crypto keyword when an info or an admin>save command is run. For security reasons, keys encrypted on one node are not usable on other nodes (that is, keys are not exchangeable between nodes).
The no form of the command removes the security association and related key values from the list of security associations for the key group. If the no form of the command is attempted using the same SPI value that is configured for active-outbound-sa, then a warning is issued and the command is blocked. If the no form of the command is attempted on the last SPI in the key group and the key group is configured on a service, then the command is blocked.
n/a
This command configures the group encryption label used to identify when an MPLS payload is encrypted. This label must be unique network-wide and must be configured consistently on all nodes participating in a network group encryption domain. The label cannot be changed or deleted when there are any key groups configured on the node.
The no form of the command reverts to the default setting.
n/a
This command accesses the show>group encryption context.
This command displays NGE information for a key group.
