DGS-1510 Series Gigabit Ethernet SmartPro 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)# 26-7 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)# 236
