Configuring ARP-Inspection
Introduction
The ARP Inspection function is dedicated to defense against attacks which use ARP (for instance, ARP-
spoofing – ARP traffic interception). ARP Inspection is implemented on the basis of static correspondence
between IP and MAC addresses defined for VLAN.
20.1
Configuring ARP-Inspection
Step 1.
Move to view in switch configuration by using
switch
and
configure
commands.
LTP-8X# switch
LTP-8X(switch)# configure
LTP-8X(switch)(config)#
Step 2.
Activate
arp inspection
and add static entries
LTP-8X(switch)(config)# ip arp-inspection
LTP-8X(switch)(config)# ip arp inspection static-table 1.1.1.1 A8:F9:4B:11:11:01
LTP-8X(switch)(config)# ip arp inspection static-table 1.1.1.2 A8:F9:4B:11:11:10 vlan 10
Step 3.
Configure trusted and untrusted interfaces
LTP-8X(switch)(config)# interface front-port 7
LTP-8X(switch)(config-if)# no ip arp inspection trusted
LTP-8X(switch)(config)# interface front-port 0 – 6
LTP-8X(switch)(config-if)# ip arp inspection trusted
Step 4.
Apply the configuration by using
commit
command.
LTP-8X(switch)(config)# commit
20.2
QoS configuration
Configuring QoS rules
The traffic prioritization and allocation by hardware queues (IEEE 802.1p/DSCP) are implemented on the
basis of set rules in the system.
