Virtual sensors for IPS
8.0(2)
The AIP SSM running IPS software Version 6.0 and above
can run multiple virtual sensors, which means you can
configure multiple security policies on the AIP SSM. You
can assign each context or single mode ASA to one or more
virtual sensors, or you can assign multiple security contexts
to the same virtual sensor.
We introduced the following command: allocate-ips.
Automatic MAC address assignment
enhancements
8.0(5)/8.2(2)
The MAC address format was changed to use a prefix, to use
a fixed starting value (A2), and to use a different scheme for
the primary and secondary unit MAC addresses in a failover
pair. The MAC addresses are also now persistent across
reloads. The command parser now checks if auto-generation
is enabled; if you want to also manually assign a MAC
address, you cannot start the manual MAC address with A2.
We modified the following command: mac-address auto
prefix.
