LABEL DESCRIPTION
Interface Properties
Interface Name This field is read-only. It displays the name of the virtual interface, which is
automatically derived from the underlying Ethernet interface, VLAN interface, or bridge
interface.
Description Enter a description of this interface. It is not used elsewhere. You can use alphanumeric
and
()+/:=?!*#@$_%- characters, and it can be up to 60 characters long.
IP Address
Assignment
IP Address Enter the IP address for this interface.
Subnet Mask Enter the subnet mask of this interface in dot decimal notation. The subnet mask
indicates what part of the IP address is the same for all computers in the network.
Gateway Enter the IP address of the gateway. The ISG50 sends packets to the gateway when it
does not know how to route the packet to its destination. The gateway should be on the
same network as the interface.
Metric Enter the priority of the gateway (if any) on this interface. The ISG50 decides which
gateway to use based on this priority. The lower the number, the higher the priority. If
two or more gateways have the same priority, the ISG50 uses the one that was
configured first.
Interface
Parameters
Egress
Bandwidth
Enter the maximum amount of traffic, in kilobits per second, the ISG50 can send
through the interface to the network. Allowed values are 0 - 1048576.
