Olicom 8600, 8605 manual Operation Mode, Forwarding Mode, Priority Threshold

107

Operation Mode

The port operation mode. Possible values are as follows:

•

•

•

•

•

•

Auto (default. Only HDX and FDX modes can be automatically detected.)

HDX port

HDX station

FDX port

FDX station

RI/RO

(on CrossFire 8600 only on ports 19 and 20 and on fiber expansion modules, on CrossFire 8605 on all 20 fiber ports and on fiber expansion modules)

•Passive

(this value is not user-selectable, and will be displayed if the port has been selected as a passive monitoring port on the Switched Port Analyzer screen).

➽Note: Connecting to other Non IEEE 802.5j compliant fiber devices:

When connecting ports on the CrossFire 8605 or on a fiber module (CrossFire 8611) to non IEEE 802.5j compliant devices (typically older fiber equipment such as the Olicom OC-3610 CAU), the switch fiber ports should manually be configured to RI/RO mode in order to make sure, that a connection can be established. If the other fiber equipment supports FDX connections (such as the CrossFire 8100 Token-Ring Switch), the switch fiber ports should manually be set to FDX port mode in order to make an FDX fiber connection.

➽Note: When connecting one switch to another switch using the CrossFire 8611 UEM, one end of the fiber connection must be manually configured as ADAPTER, and the other end as PORT in the Port Configuration menu.

Forwarding Mode

Forwarding mode that will be used to transmit frames. Possible values are auto, cut- through, and store & forward. The default is auto. If the forwarding mode is set to auto, the actual mode will depend on the number of errors that occur during the sampling interval. If the error rate is below the error low threshold, then cut-throughmode is used. If the error rate is above the error high threshold, then store & forward is used. The store & forward mode is always used for ports with a media speed of 4 Mbps.

Priority Threshold

The highest Token-Ring frame priority that will go to the low priority transmit queue. Possible values are 0– 7. The default value is 3).
