For example, the Address Filters Default Action may be to discard all frames des-

tined for addresses not matched in the configuration database. Therefore if the

address type field is not matched, the frame will be discarded. But if an address type

field is matched in the database, the frame will be forwarded for that address.

Conversely, if the default action is to forward all frames destined for addresses

not matched in the configuration database, those frames will be passed on for

those addresses, but frames for an address type field matched in the database will

be discarded.

Protocol Filters Enabled

The checkbox in this parameter enables or disables the Protocol Filters function. If

filtering is enabled (

√ ), frames are filtered and either forwarded or discarded,

depending on the rest of the settings in this configuration. If filtering is disabled, no

filtering will be done based on protocol frames.

Protocol Default Action

This parameter determines which Protocol Default Action (discard or forward) will

be performed when the Protocol Filters Enabled parameter is checked (

√). Each

Protocol Filter (see page 83) also has a forward/discard action associated with it. If a

frame does not match any of the filters set in the Protocol Filters configuration, then

it will take the Protocol Default Action selected in this parameter.

For example, the Protocol Default Action may be to discard all frames. If a type

field is matched in the configuration database, and the Filters action is forward, the

frame will be passed on. If the field is not matched, then the frame will be dis-

carded. Therefore if you want only IP frames forwarded, after selecting the appro-

priate IP Type in the Ethernet II Filters (see page 86) the discard setting here will

drop all frames containing other protocol types.

Important: If Protocol Filters Enabled is checked, and the Protocol Default

Action is discard, an HTTP browser will not be able to access the

9150’s configuration pages unless an ARP filter is defined to

forward ARP packets. To do this, configure Ethernet II Filters to

forward protocol type 0x0806 (ARP) packets (see page 86). Alterna-

tively, you can create a static entry in the ARP table on the compu-

ter that is running the browser.
