First/Second/Third DNS
Server
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 a system DNS server (in the
order you specify here) to resolve domain names for content filtering, the
time server, etc.
If you have the IP address(es) of the DNS server(s), enter the DNS server's
If you have the IP address(es) of the DNS server(s), enter the DNS server's

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
The lower the numeric value you assign, the higher the priority for this
bridge.

Time, Max Age and Forward Delay.
Bridge Hello Time
Enter an
interval (between 1 and 10) in seconds that the root bridge
waits before sending a hello packet.
Bridge Max Age
Enter an interval
(between 6 and 40) in seconds
that a bridge waits to
get a Hello BPDU from the root bridge.
Forward Delay
Enter the length of time
(between 4 and 30) in seconds
that a bridge
remains in the listening and learning port states. The default is 15 seconds.
Bridge Port
This is the bridge port type.
RSTP Active
Select the check box to enable RSTP on the corresponding port.
RSTP Priority
0(Highest)~240(Lowest)
Enter a number between 0 and 240 as RSTP priority for the corresponding
port. 0 is the highest.
RSTP Path Cost
1(Lowest)~65535(Highe
