Parameter Description
Policy Name
Enter the policy name used here. This name can be up to 32 characters long.
Device Role Select the device role here. Options to choose from are Host and Router. By
default, the device's role is set as host and inspection for NS and NA messages
are performed. If the device role is set as router, the NS and NA inspection is not
performed. When performing NS/NA inspection, the message will be verified
against the dynamic binding table learned from the ND protocol or from the DHCP.
Mode
Select the mode of ND inspection here. Options to choose from are:
• Precise - Specifies to use the precise mode. ND inspection checks if the
target address is the same as the source address in DANA/NA packets.
• Fuzzy - Specifies to use the fuzzy mode. ND inspection checks if both the
target and the source addresses exist in the binding table.
Validate Source-MAC
Select to enable or disable the validation of the source MAC address option here.
When the Switch receives an ND message that contains a link-layer address, the
source MAC address is checked against the link-layer address. The packet will be
dropped if the link-layer address and the MAC addresses are different from each
other.
Target Port
Tick this option to specify the target port.
Unit
Select the Switch unit that will be used for this configuration here.
From Port - To Port
Select the appropriate port range used for the configuration here.
Click the Apply button to accept the changes made.
