EDSC(4) 						   BSD Kernel Interfaces Manual 						   EDSC(4)

NAME

     edsc -- Ethernet discard network interface

SYNOPSIS

     device edsc

DESCRIPTION

     The edsc interface is a software discard mechanism which may be used for performance analysis and software testing.  It imitates an Ethernet
     device, which allows for its use in conjunction with such drivers as if_bridge(4) and vlan(4).

     As with other network interfaces, an edsc interface must have network addresses assigned for each address family with which it is to be used.
     These addresses may be set or changed with the SIOCSIFADDR ioctl(2) or ifconfig(8) utility.

     Each edsc interface is created at runtime using interface cloning.  This is most easily done with the ifconfig(8) create command or using the
     cloned_interfaces variable in rc.conf(5).

SEE ALSO

     ioctl(2), arp(4), if_bridge(4), inet(4), intro(4), vlan(4), rc.conf(5), arp(8), ifconfig(8)

HISTORY

     The edsc device was derived from the disc(4) device and first appeared in FreeBSD 6.3.  This manpage was adapted from disc(4).

CAVEATS

     Since outgoing packets are just discarded by edsc, ARP requests stay unreplied.  Consequently, an IP packet cannot be sent via edsc until a
     static arp(4) entry is created for its next hop using arp(8).

     Initially an edsc interface has a zero link level address.  It can be changed with ifconfig(8) lladdr if needed.
