ZyWALL 2 Plus User’s Guide

Use the Port Roles screen to set ports as part of the LAN, DMZ and/or WLAN interface. 
Ports 1~4 on the ZyWALL can be part of the LAN, DMZ or WLAN interface. 
To change your ZyWALL’s port role settings, click NETWORK > BRIDGE > Port Roles. 
The screen appears as shown.
The radio buttons correspond to Ethernet ports on the front panel of the ZyWALL. On the 
ZyWALL, ports 1 to 4 are all LAN ports by default.

Bridge Priority

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 

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

st)

Enter a number between 1 and 65535 as RSTP path cost for the 

corresponding port. 65535 is the highest.
