your network. By default, the Cayman 2E-W uses 192.168.1.254 as its
LAN IP address.
set ip ethernet [ A | B ] broadcast broadcast_address
Specifies the broadcast address for the TCP/IP network connected to
the designated Ethernet port. IP hosts use the broadcast address to
send messages to every host on your network simultaneously.
The broadcast address for most networks is the network number
followed by 255. For example, the broadcast address for the
192.168.1.0 network would be 192.168.1.255.
set ip ethernet [ A | B ] netmask netmask
Specifies the subnet mask for the TCP/IP network connected to the
Ethernet port. The subnet mask specifies which bits of the 32-bit
binary IP address represent network information. The default subnet
mask for most networks is 255.255.255.0 (Class C subnet mask).
set ip ethernet A restrictions { none | admin-disabled }
set ip ethernet B restrictions { none | admin-disabled |
admin-only }
Specifies whether an administrator can open a Telnet connection to
the Cayman 2E-W over the designated Ethernet interface to monitor
and configure the Cayman 2E-W. On the Cayman 2E-W LAN port, you
can enable or disable administrator access. On the WAN port, you
can enable or disable administrator access or specify that the WAN
port can only be used for administrative traffic. By default,
administrative restrictions are turned off on both Ethernet ports,
meaning an administrator can open a Telnet connection through
either port.
If you specify admin-only access for the Cayman 2E-W
WAN port, you will turn off routing services through that
port. Do not turn on admin-only access without consulting
with your network administrator.
