Mirror Setting

Port Mirroring is a method of monitoring network traffic that forwards a copy of each incoming and/or outgoing packet from one port of a network switch to

another port where the packet can be studied. It enables the manager to keep close track of switch performance and alter it if necessary.

Configuring the port mirroring by assigning a source port from which to copy all packets and a sniffer port where those packets will be sent.

The selection of the sniffer mode is as follows:

TX (transmit) mode: This mode will duplicate the data transmitted from the source port and forward it to the sniffer port.

SNMP enables network management stations to read and modify the settings of gateways, routers, switches, and other network devices. Use SNMP to

configure system features for proper operation, monitor performance and detect potential problems in the Switch, switch group or network.

Managed devices that support SNMP include software (referred to as an agent), which runs locally on the device. A defined set of variables (managed

objects) is maintained by the SNMP agent and used to manage the device. These objects are defined in a Management Information Base (MIB), which

the protocol used to access this information over the network.

The Switch supports the SNMP versions 1. In SNMP v.1, user authentication is accomplished using 'community strings', which function like passwords. The

remote user SNMP application and the Switch SNMP must use the same community string. SNMP packets from any station that has not been authenticated

are ignored (dropped).

addition to the standard MIB-II, the Switch also supports its own proprietary enterprise MIB as an extended Management Information Base. The proprietary

MIB may also be retrieved by specifying the MIB Object Identifier. MIB values can be either read-only or read-write.
