Port {#SNMPINDEX}: Speed Duplex

MIB: ZYXEL-PORT-MIB

Select The speed and the duplex mode of the Ethernet connection on this port. Selecting Auto

(auto-negotiation) allows one port to negotiate with a peer port automatically to obtain the

connection speed and duplex mode that both ends support. When auto-negotiation is turned on,

a port on the Switch negotiates with the peer automatically to determine the connection speed

and duplex mode. If the peer port does not support auto-negotiation or turns off this feature,

the Switch determines the connection speed by detecting the signal on the cable and using half

duplex mode. Thus requiring you to make sure that the settings of the peer port are the same in

order to connect.

ZYXEL: Port {#SNMPINDEX}: Link down

This trigger expression works as follows:
1. It can be triggered if the operations status is down.
2. {$IFCONTROL:"{#IFNAME}"}=1 - a user can redefine context macro to value - 0. That marks this interface as not important. No new trigger will be fired if this interface is down.
3. {TEMPLATE_NAME:METRIC.diff()}=1 - the trigger fires only if the operational status was up to (1) sometime before (so, do not fire for the 'eternal off' interfaces.)

WARNING: if closed manually - it will not fire again on the next poll, because of .diff.
