network administrator can manage, control and monitor the switch from the console program.

The VH-8G-L3 contains a CPU, memory for data storage, flash memory for configuration data, operational programs, and SNMP agent firmware. These components allow the switch to be actively managed and monitored from either the console port or the network itself (out-of-band, or in-band).

SNMP Management

The Simple Network Management Protocol (SNMP) is an OSI layer 7 (the application layer) protocol for remotely monitoring and configuring network devices. SNMP enables network management stations to read and modify the settings of gateways, routers, switches, and other network devices. SNMP can be used to perform many of the same functions as a directly connected console, or can be used within an integrated network management software package such as NetSight.

Flow Control

The VH-8G-L3 supports flow control (back pressure handling) on a per-port basis. The limit at which flow control is applied to a port is based on the amount of memory used by the packets on an input port.

• 802.3x Flow Control – if the port is configured in full duplex mode, a MAC PAUSE packet is sent to inhibit the flow of packets to the port for a short amount of time.

 

Spanning Tree Protocol

 

The VH-8G-L3 switch complies with the IEEE 802.1D

 

Spanning Tree Protocol standard and allows for the blocking

 

of links between switches that form loops within the network.

 

When multiple links between switches are detected, a

 

primary link is established. Duplicated links are blocked from

 

use and become standby links. The protocol allows for the

15

duplicate links to be used in the event of a failure of the
