• Use the
ARP Inspe c tio n VLAN Sta tus
screen (
Section 26.8 on page 249
) to look at various statistics
about ARP packets in each VLAN.
• Use the
ARP Inspe c tio n Lo g Sta tus
screen (
Section 26.9 on page 249
) to look at log messages that
were generated by ARP packets and that have not been sent to the syslog server yet.
• Use the
ARP Inspe c tio n C o nfig ure
screen (
Section 26.10 on page 251
) to enable ARP inspection on
the Switch. You can also configure the length of time the Switch stores records of discarded ARP
packets and global settings for the ARP inspection log.
• Use the
ARP Inspe c tio n Po rt C o nfig ure
screen (
Section 26.10.1 on page 252
) to specify whether ports
are trusted or untrusted ports for ARP inspection.
• Use the
ARP Inspe c tio n VLAN C o nfig ure

inspection on each VLAN and to specify when the Switch generates log messages for receiving ARP
packets from each VLAN.
26.1.2 Wha t Yo u Ne e d to Kno w
The Switch builds the binding table by snooping DHCP packets (dynamic bindings) and from information
provided manually by administrators (static bindings).
IP source guard consists of the following features:
• Static bindings. Use this to create static bindings in the binding table.
• DHCP snooping. Use this to filter unauthorized DHCP packets on the network and to build the binding
table dynamically.
• ARP inspection. Use this to filter unauthorized ARP packets on the network.
If you want to use dynamic bindings to filter unauthorized ARP packets (typical implementation), you
have to enable DHCP snooping before you enable ARP inspection.
