Configuring ACL Bindings with CLI Commands
The following table summarizes the equivalent CLI commands for configuring ACL Bindings.
The following is an example of some of the CLI commands:
Configuring DHCP Snooping
DHCP Snooping expands network security by providing firewall security between untrusted interfaces
and DHCP servers. By enabling DHCP Snooping network administrators can differentiate between
trusted interfaces connected to end-users or DHCP Servers and untrusted interfaces located beyond the
network firewall.
DHCP Snooping filters untrusted messages. DHCP Snooping creates and maintains a DHCP Snooping
Table which contains information received from untrusted packets. Interfaces are untrusted if the packet
is received from an interface outside the network or from an interface beyond the network firewall.
Trusted interfaces receive packets only from within the network or the network firewall.
The DHCP Snooping Table contains the untrusted interfaces’ MAC address, IP address, Lease Time,
VLAN ID, and interface information.
The DHCP section contains the following topics:
• Defining DHCP Snooping Properties
• Defining DHCP Snooping on VLANs
• Defining Trusted Interfaces
• Adding Interfaces to the DHCP Snooping Database
