2.5.2 Switch Setting

2.5.2.1 Advanced

±

Miscellaneous Setting:

MAC Address Age-out Time:

Type the number of seconds that an inactive MAC address remains in the

switch's address table. The valid range is 300~765 seconds. Default is 300 seconds.

Max bridge transit delay bound control:

Limit the packets queuing time in switch. If enable, the

packets queued exceed will be drop. These valid values are 1sec, 2 sec, and 4 sec and off. Default is 1

seconds.

- 21 -

NOTE:

Make sure of “Max bridge transit delay bound control” is enabled before enable Delay Bound,

because Enable Delay Bound must be work under “Max bridge transit delay bound control is enabled”

situation.

Broadcast Storm Filter:

To configure broadcast storm control, enable it and set the upper threshold for

individual ports. 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 control becomes

active. The valid threshold value is 5%, 10%, 15%, 20%, 25% and

off

.

±

Priority Queue Service settings:

First Come, First Serve:

The sequence of packets sent is depending on arrive orders.

All High before Low:

The high priority packets sent before low priority packets.

WRR:

Weighted Round Robin. Select the preference given to packets in the switch's high-priority

queue. These options represent the number of high priority packets sent before one low

priority packet is sent. For example, 5 High

2 Low means that the switch sends 5 high-priority

packets before sending 2 low- priority packets.

Enable Delay Bound:

Limit the low priority packets queuing time in switch. Default Max Delay

Time is 255ms. If the low priority packet stays in switch exceed Max Delay

Time, it will be sent. The valid range is 1-255ms.

Qos Policy: High Priority Levels:

0~7 priority level can map to high or low queue.

2.5.2.2 Misc Config

Collisions Retry Forever:

Disable

– In half duplex, collision-retry maximum is 48 times and packet will be

dropped if collision still happen.

Enable

– In half duplex, if happen collision will retry forever.

Hash Algorithm:

Choose algorithms,

CRC-Hash

or

DirectMap,

to

maintain MAC address table.

IFG Compensation:

Enable or disable inter-frame gap (IFG) compensation.

802.1x Protocol:

Enable or disable 802.1x protocol.

2.5.3 Console Port Information

Console is a standard UART interface to communicate with Serial Port.

User can use windows HyperTerminal program to link the switch. Connect To -> Configure:

Bits per seconds: 9600

Data bits: 8

Parity: none

Stop Bits: 1

Flow control: none

2.5.4 Port Controls

User may modify or change mode operation in this page.

- 24 -

1. State:

User can disable or enable this port control.

2. Auto Negotiation:

User can set auto negotiation mode is Auto, Nway (specify the speed/duplex on

this port and enable auto-negotiation), Force of per port.

3. Speed:

User can set 100Mbps or 10Mbps speed on Port1~Port24.

User can set 1000Mbps, 100Mbps or 10Mbps speed on Port25~Port26 (depend on module card

mode).

4. Duplex:

User can set full-duplex or half-duplex mode of per port.

5. Flows control:

Full:

User can set flow control function is enable or disable in full mode.

Half:

User can set backpressure is enable or disable in half mode.

6. Rate Control:

port1 ~ port 24, supports by-port ingress and egress rate control. For example, assume

port 1 is 10Mbps, users can set its effective egress rate at 1Mbps and ingress rate at 500Kbps. Device

will perform flow control or backpressure to confine the ingress rate to meet the specified rate.

Ingress:

Type the port effective ingress rate. The valid range is 0 ~ 1000. The unit is 100K.

0: disable rate control.

1 ~ 1000: valid rate value

Egress:

Type the port effective egress rate. The valid range is 0~1000. The unit is 100K.

0: disable rate control.

1 ~ 1000: valid rate value.

7. Port Priority:

Enable or disable the port priority function. There are two priorities (high or low)

provided if port priority is enabled.
