Recently I was investigating alerts that were being generated for inbound interface discards on multiple interfaces and multiple Vyatta 5400 devices. There were not any noticeable performance issues on traffic passing through the devices. The discards would report in SNMP, show interface ethernet ethX, and ifconfig outputs. An example show interface ethernet ethX output I was reviewing is below. vyatta@FW01:~$ sh int ethernet eth0 eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000 link/ether 00:50:56:0x:0x:0x brd ff:ff:ff:ff:ff:ff inet 172.
