Chapter 6 Interfaces

 

 

Table 26 interface Commands: PPPoE/PPTP Interfaces (continued)

COMMAND

DESCRIPTION

[no] mss <536..1452>

Specifies the maximum segment size (MSS) the interface can 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 ZyWALL use its default

 

MSS setting.

 

 

mtu <576..1492>

Sets the Maximum Transmission Unit in bytes.

[no] ipv6 enable

Turns on the IPv6 interface. The no command turns it off.

[no] ipv6 nd ra accept

Sets the IPv6 interface to accept IPv6 neighbor discovery router advertisement

 

messages. The no command sets the IPv6 interface to discard IPv6 neighbor

 

discovery router advertisement messages.

[no] ipv6 metric <0..15>

Sets the interface’s metric for IPv6 traffic. The no command clears it.

[no] ipv6 address

Has the ZyWALL obtain an IPv6 prefix from the ISP or a connected uplink router

dhcp6_profile dhcp6_suffix_128

for an internal network, such as the LAN or DMZ. The no command removes the

 

specified setting for using a delegated prefix as the beginning part of the

 

network prefix.

 

dhcp6_profile: Specify the DHCPv6 request object to use.

 

dhcp6_suffix_128: Specify the ending part of the IPv6 address, a slash (/),

 

and the prefix length. The ZyWALL appends it to the delegated prefix.

 

For example, you got a delegated prefix of 2003:1234:5678/48. You want to

 

configure an IP address of 2003:1234:5678:1111::1/128 for this interface,

 

then enter ::1111:0:0:0:1/128 for the dhcp6_suffix_128.

 

 

ipv6 dhcp6 [client]

Sets the IPv6 interface to be a DHCPv6 client.

[no] ipv6 dhcp6 rapid-commit

Shortens the DHCPv6 message exchange process from four to two steps to help

 

reduce network traffic. The no command sets the full four-step DHCPv6

 

message exchange process.

 

 

[no] ipv6 dhcp6 address-

Get this interface’s IPv6 address from the DHCPv6 server. The no command has

request

the ZyWALL not get this interface’s IPv6 address from the DHCPv6 server.

ipv6 dhcp6 duid { duid mac }

Specify the DHCP Unique IDentifier (DUID) of the interface or have it generated

 

from the interface’s default MAC address.

 

 

[no] ipv6 dhcp6-request-object

For a DHCPv6 client interface, specify the profile of DHCPv6 request settings

dhcp6_profile

that determine what additional information to get from the DHCPv6 server. The

 

no command removes the DHCPv6 request settings profile.

show interface ppp system-default

Displays system default PPP interfaces (non-deletable) that come with the

 

ZyWALL.

 

 

show interface ppp user-define

Displays all PPP interfaces that were manually configured on the ZyWALL.
