Aging Time
The 604/608MFX monitors the age of the addresses it has learnt, and
addresses that exceed a certain age (aging time, default setting = 40 sec), are
deleted again by the switch. If a packet with a source address matching the
address entry is received before the aging time elapses, the address entry is
retained, and the age is reset. If a packet is received and there is no address
entry for the source address, it is learnt. If a packet is received and there is
no address entry for the destination address, it is sent to all ports.
IEEE 802.1Q, VLAN
The 600 Series switches do not support VLAN tags according to IEEE
802.1Q. Users must configure their networks so that no VLAN packets are
sent.
IEEE 802.1P, QOS
The 600 Series does support QOS. Users should configure their networks
such that no packets with a priority tag higher than 3 are transmitted since
these packets can influence redundancy functions (for example, longer
switchover times if a fault develops, or false fault detection).
Two-Pin Dip Switch Setting
With the two-pin DIP switch on the upper casing of the 604/608MFX, you
can do the following:
With the Stby button, you can activate the standby function of the
device (608 only). This switch is not connected in the 604MFX.
With the RM switch, you can activate the redundancy manager
function of the device.
Note: The switch must be restarted after changing the DIP switch
Settings. The switch settings are only adopted when the device powers
Up.
