Commands for Security Function Chapter 6 Commands for TACACS+
13.4 anti-arpscan trust
Command:
anti-arpscan trust [port | supertrust-port]
no anti-arpscan trust [port | supertrust-port]
Function:
Configure a port as a trusted port or a super trusted port;” no anti-arpscan trust <port |
supertrust-port>”command will reset the port as an untrusted port.
Parameters:
None.
Default Settings:
By default all the ports are non- trustful.
Command Mode:
Port configuration mode
User Guide:
If a port is configured as a trusted port, then the ARP scanning prevention function will not deal with
this port, even if the rate of received ARP messages exceeds the set threshold, this port will not be
closed, but the non- trustful IP of this port will still be checked. If a port is set as a super non- trustful
port, then neither the port nor the IP of the port will be dealt with. If the port is already closed by ARP
scanning prevention, it will be opened right after being set as a trusted port.
When remotely managing a switch with a method like telnet, users should set the uplink port as a
Super Trust port before enabling anti-ARP-scan function, preventing the port from being shutdown
because of receiving too many ARP messages. After the anti-ARP-scan function is disabled, this
port will be reset to its default attribute, that is, Untrust port.
Example:
Set port ethernet 4/5 of the switch as a trusted port.
Switch(config)#in e4/5
Switch(Config-If-Ethernet4/5)# anti-arpscan trust port
13.5 anti-arpscan trust ip
Command:
anti-arpscan trust ip <ip-address> [<netmask>]
no anti-arpscan trust ip <ip-address> [<netmask>]
Function:
Configure trusted IP;” no anti-arpscan trust ip <ip-address> [<netmask>]”command reset the IP
