3-4-5. Misc. Feature Configuration

Miscellaneous Feature Configuration gathers many functions, including MAC

Address Aging Time Setting, Broadcast Storm Filter Limit, Priority Queue Service,

Max. bridge transmit delay bound control and QoS Policy in a page, which cannot

be categorized to some function type. They are described below.

Function Name:

MAC Address Aging Time Setting

Function Description:

This function is used to set the MAC Address Age-out Time applied to the

whole MAC address table except some static MAC address. The range of

MAC table address entry age-out time is from 30, 33, 36,…765 seconds.

If a source node has not visited the converter for a time longer than the Age-

out Time, its responded MAC address information in the converter’s MAC table

will be marked invalid by the converter’s aging function. This age-out rule will

not be applied to the static MAC addresses.

The default age-out time is 300 seconds.

Function Name:

Broadcast Storm Filter Limit

Function Description:

Broadcast Storm Filter Limit is applied to filter the converter’s broadcast traffic.

If you choose an upper threshold, it is enabled. It is a global function. The

setting will be applied to all ports of the converter.

The threshold is the percentage of the port's total bandwidth used by

broadcast traffic. When broadcast traffic for a port rises above the threshold

you set, broadcast storm filter discards the extra broadcast traffic. This keeps

the total broadcast traffic less than the threshold able to be forwarded and

limits too many broadcast packet running over the network. Signamax 065-

1600 series supports five threshold values, including 5%, 10%, 15%, 20%, and

25%.

Default is OFF.
