DXS-3600 Series Layer 3 Managed 10Gigabit Ethernet Switch CLI Reference Guide
Usage Guideline
Use the command to configure the maximum entry number of the log buffer. The ARP inspection log
buffer keeps tracks the information of ARP packet. The first packet that is given by check will be sent to
syslog module and recorded in the inspection log buffer. The subsequent packets belonging to the same
session will not be sent to log module unless its record in the log buffer is cleared. If the log buffer is full
but more logging events, the event will not be logged. If the user specifies a buffer size less than the
current entry number, then the log buffer will be automatically cleared.
Example
This example shows how to change the maximum buffer number to 64.
Switch# configure terminal
Switch(config)# ip arp inspection log-buffer entries 64
Switch(config)#
33-7 ip arp inspection trust
This command is used to trust an interface for dynamic ARP inspection. Use the no form of the command
to disable the trust state.
ip arp inspection trust
no ip arp inspection trust
Parameters
None.
Default
By default, this option is disabled.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
When an interface is in the trust state, the ARP packets arriving at the interface will not be inspected.
When an interface is in the untrusted state, ARP packets arriving at the port and belongs to the VLAN that
is enabled for inspection will be inspected.
Example
This example shows how to configure port 3/0/3 to be trusted for DAI.
Switch# configure terminal
Switch(config)# interface eth3/0/3
Switch(config-if)# ip arp inspection trust
Switch(config-if)#
33-8 ip arp inspection validate
