About Auto Security
Prior to Release IOS XE 3.6.0E and IOS 15.2(2)E, the Catalyst 4500 series switch offered IPv4 baseline
security features (like Port Security), which must be enabled globally and on per port basis. Moreover,
the baseline security feature CLIs for uplink ports differ from those for downlink CLIs.
Beginning with Release IOS XE 3.6.0E and IOS 15.2(2)E, the Catalyst 4500 series switch supports Auto
Security (AS), which provides a single line CLI, to enable base line security features.
AS supports the IPv4 baseline security features: DHCP Snooping, Dynamic ARP Inspection, and Port
Security.
Feature Interaction
Auto security interacts with Port Security, DHCP snooping, DAI modules.
DHCP Snooping
Auto Security (AS) enables DHCP Snooping globally (with the ip dhcp snooping command) and also
on VLANs 2-1005 (with the ip dhcp snooping vlan vlanid command).
