DESCRIPTION
DNS (Domain Name System) is for mapping a domain name to its
corresponding IP address and vice versa. The DNS server is extremely
important because without it, you must know the IP address of a machine
before you can access it. The ZyWALL uses the DNS server (in the order
you specify here) to resolve domain names for things like the time server.
Enter the DNS server IP address(es) in the field(s) to the right.
Select the check box to activate RSTP on the ZyWALL.
Enter a number between 0 and 61440 as bridge priority of the ZyWALL.
Bridge priority is used in determining the root switch, root port and
designated port. The switch with the highest priority (lowest numeric value)
becomes the root. If multiple devices have the lowest priority, the device
with the lowest MAC address becomes the root.
The lower the numeric value you assign, the higher the priority for this
bridge.
Bridge Priority determines the root bridge, which in turn determines Hello
