Dynamic Ipsg Bindings; Ipsg Configuration Task List - HP FlexNetwork 10500 Series Security Configuration Manual

Dynamic IPSG bindings

IPSG automatically obtains user information from other modules to generate dynamic bindings. The
source modules include 802.1X, DHCP relay, DHCP snooping, DHCPv6 snooping, and DHCP
server.
DHCP-based IPSG bindings are suitable for scenarios where hosts on a LAN obtain IP addresses
through DHCP. IPSG is configured on the DHCP snooping device or the DHCP relay agent. It
generates dynamic bindings based on the DHCP snooping entries or DHCP relay entries. IPSG
allows only packets from the DHCP clients to pass through.
Dynamic IPv4SG
Dynamic bindings generated based on different source modules are for different usages:
Interface types
Layer 2 Ethernet port
Layer 3 Ethernet
interface/VLAN interface
For more information about 802.1X, see
snooping, DHCP relay, and DHCP server see Layer 3—IP Services Configuration Guide.
Dynamic IPv6SG
IPv6SG on an interface obtains information from DHCPv6 snooping entries to generate bindings for
packet filtering.
For more information about DHCPv6 snooping, see Layer 3—IP Services Configuration Guide.
