ZyWALL (ZLD) CLI Reference Guide

show interface send statistics interval

Displays the interval for how often the ZyWALL refreshes the sent 
packet statistics for the interfaces.

show interface summary all 

Displays basic information about the interfaces.

show interface summary all status

Displays the connection status of the interfaces.

[no] interface interface_name

Creates the specified interface if necessary and enters sub-command 
mode. The 

no

 command deletes the specified interface.

[no] description description

Specifies the description for the specified interface. The 

no

 command 

clears the description.

: You can use alphanumeric and 

()+/:=?!*#@$_%-

 

characters, and it can be up to 60 characters long.

[no] downstream <0..1048576>

This is reserved for future use.

Specifies the downstream bandwidth for the specified interface. The 

no

 

command sets the downstream bandwidth to 1048576.

exit

Leaves the sub-command mode.

[no] ip address dhcp

Makes the specified interface a DHCP client; the DHCP server gives the 
specified interface its IP address, subnet mask, and gateway. The 

no

 

command makes the IP address static IP address for the specified 
interface. (See the next command to set this IP address.)

[no] ip address ip subnet_mask

Assigns the specified IP address and subnet mask to the specified 
interface. The 

no

 command clears the IP address and the subnet mask.

[no] ip gateway ip

Adds the specified gateway using the specified interface. The 

no

 

command removes the gateway.

ip gateway ip metric <0..15>

Sets the priority (relative to every gateway on every interface) for the 
specified gateway. The lower the number, the higher the priority.

[no] metric <0..15>

Sets the tunnel, PPPoE/PPTP, or cellular interface’s priority relative to 
other interfaces. The lower the number, the higher the priority.

[no] mss <536..1460>

Specifies the maximum segment size (MSS) the interface is to use. MSS 
is the largest amount of data, specified in bytes, that the interface can 
handle in a single, unfragmented piece. The 

no

 command has the 

interface use its default MSS.

[no] mtu <576..1500>

Specifies the Maximum Transmission Unit, which is the maximum 
number of bytes in each packet moving through this interface. The 
ZyWALL divides larger packets into smaller fragments. The 

no

 

command resets the MTU to 1500.

[no] shutdown

Deactivates the specified interface. The 

no

 command activates it.

traffic-prioritize {tcp-ack|content-

filter|dns|ipsec-vpn|ssl-vpn} 

bandwidth <0..1048576> priority 

<1..7> [maximize-bandwidth-usage];

Applies traffic priority when the interface sends TCP-ACK traffic, traffic 
for querying the content filter, traffic for resolving domain names, or 
encrypted traffic for an IPSec or SSL VPN tunnel. It also sets how much 
bandwidth the traffic can use and can turn on maximize bandwidth 
usage.  

traffic-prioritize {tcp-ack|content-

filter|dns|ipsec-vpn|ssl-vpn} 

deactivate

Turns off traffic priority settings for when the interface sends the 
specified type of traffic. 

[no] upstream <0..1048576>

Specifies the upstream bandwidth for the specified interface. The 

no

 

command sets the upstream bandwidth to 1048576.

interface interface_name ipv6

Creates the specified IPv6 interface if necessary and enters sub-
command mode. 

address ipv6_addr_prefix

Sets an IPv6 address with prefix for the interface.

gateway ipv6_addr metric <0..15>

Sets the specified IPv6 address’s metric.
