Aging
OSMs/ESMs automatically learn the source addresses of the nodes connected to
them. This information is used on the OSM/ESM to pass packets to the intended
recipients. This reduces the network load for the other nodes.
If the OSM/ESM does not receive a packet with a source address that matches a
learned address within the aging time, it deletes the address from the database.
This prevents packets being passed on incorrectly if, for example, a DTE is
connected to a different OSM/ESM port. The default for the aging time is 40
seconds. By setting aging to disabled, addresses are no longer automatically
deleted.
Flow Control
Using flow control, the OSM/ESM can slow down the reception of further packets
at the ports if the network is overloaded. Flow control must be activated separately
for the individual ports in the port mask. If the Flow Control Enable check box is
deactivated in the Switch window, the flow control mechanism is deactivated for all
ports regardless of the settings made in the port masks.
Set New Value
Follow the steps outlined below to change settings in the Switch window:
1. First, enable the check box for the individual parameters by clicking them or
select the mirrored port or monitor port from the list boxes.
2. Then click the Set New Values button to enter the values.
