Overview

and GMRP handle frames under GARP, and how to configure the switch ports to take advantage of this operation, refer to Local Management User’s Guide .

1.1.10 Flow Control

Flow control is a method of managing the flow of frames between two devices. It ensures that a transmitting device does not overwhelm a receiving device with data. This enables the receiving device to communicate with the transmitting device, and to have it pause its transmission while the receiving device processes the frames already received. Both devices must support the

IEEE 802.3x standard for flow control to work.

The SmartSwitch modules support the following two types of flow control:

•frame based 802.3x

•back pressure

Frame based 802.3x flow control is supported on all Ethernet ports operating in the full duplex mode. Flow control can be enabled or disabled on a port-by-port basis.

Back pressure flow control is supported on all Ethernet ports operating in the standard mode of operation. Flow control can be enabled or disabled on a port-by-port basis.

1.1.11 802.1 Port Priority

IEEE 802.1 port priority is incorporated in the IEEE 802.1D standard. It is used to assign a default priority to the frames received without priority information in their tag header, to map prioritized frames to the appropriate transmit queues, and to prioritize frames according to protocol type.

1.1.12 Management

Management of the SmartSwitch modules and 6C105 chassis is accomplished using the Local Management application or remote SNMP management stations. Local Management is accessible through the RS232 COM port on the front panel using a local VT100 terminal, or a remote VT100 terminal via a modem connection, and in-band via a Telnet connection. In-band remote management is possible through any SNMP compliant Network Management Software.

Local Management, as described in your Local Management User’s Guide , provides the ability to manage the SmartSwitches and offers information for Ethernet HSIMs or VHSIMs. Local Management information for non-Ethernet HSIMs or VHSIMs is included in their respective user’s guide. For details on how to get manuals, refer to the Related Manuals section in the About This Guide section.
