[no] description description Specifies the description for the specified interface.
The
no command clears the description.
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 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.
