Crypto Map config commands

Usage Guidelines
RFController(config-crypto-map)#set peer name
If no peer IP address is configured, the manual crypto map is not valid and not complete. A peer IP
address is required for manual crypto maps. To change the peer IP address, the no set peer
command must be issued first; then the new peer IP address can be configured.
RFController(config-crypto-map)#set pfs
If left at the default setting, no perfect forward secrecy (PFS) is used during IPSec SA key
generation. If PFS is specified, the specified Diffie-Hellman Group exchange is used for the initial
(and all subsequent) key generations. This means no data linkage between prior keys and future
keys.
RFController(config-crypto-map)#set security-association lifetime
(kilobytes|seconds)
Values can be entered in both kilobytes and seconds. Whichever limit is reached first, ends the
security association.
RFController(config-crypto-map)#set session-key [inbound|outbound]{ah|esp}
RFController(config-crypto-map)#set session-key [inbound|outbound] ah <hexkey
data>
RFController(config-crypto-map)#set session-key [inbound|outbound] esp <SPI>
cipher <hexdata key> authenticator <hexkey data>
The inbound local SPI (security parameter index) must equal the outbound remote SPI. The
outbound local SPI must equal the inbound remote SPI. The key values are the hexadecimal
representations of the keys.
They are not true ASCII strings. Therefore, a key of 3031323334353637 represents “01234567”.
RFController(config-crypto-map)#set transformset name
session-key
[inbound|outbound]
{ah|esp}
<256-4294967295>
cipher
Use the set session-key command to define the encryption and
authentication keys for this crypto map
inbound [ah|esp] – Defines encryption keys for inbound
traffic
outbound [ah|esp] Defines encryption keys for outbound
traffic
For information on how to create a key for authentication and
encryption, refer Usage Guideline in Global Configuration
commands under crypto on page 233.
ah <256-4294967295> Authentication header protocol
<256-4294967295> – Security Parameter Index (SPI)
for the security association
esp <256-4294967295>Encapsulating security payload
protocol
<256-4294967295> cipher – Defines the security
parameter index
cipher – Specify encryption/decryption key
authenticator <hex key data> Specify an authentication key
transformset <name> Use the set transform-set command to assign a transform-set to a
crypto map
