Managing Device Diagnostics Configuring Port and VLAN Mirroring 7 • MGBLH1: 1000BASE-LH SFP transceiver, for single-mode fiber, 1310 nm wavelength, supports up to 40 km. • MGBLX1: 1000BASE-LX SFP transceiver, for single-mode fiber, 1310 nm wavelength, supports up to 10 km. • MGBSX1:1000BASE-SX SFP transceiver, for multimode fiber, 850 nm wavelength, supports up to 550 m. • MGBT1: 1000BASE-T SFP transceiver for category 5 copper wire, supports up to 100 m. To view the results of optical tests, click Administration > Diagnostics > Optical Module Status. The Optical Module Status page opens. This page displays the following fields: • Port-Port number on which the SFP is connected. • Temperature-Temperature (Celsius) at which the SFP is operating. • Voltage-SFP's operating voltage. • Current-SFP's current consumption. • Output Power-Transmitted optical power. • Input Power-Received optical power. • Transmitter Fault-Remote SFP reports signal loss. Values are True, False, and No Signal (N/S). • Loss of Signal-Local SFP reports signal loss. Values are True and False. • Data Ready-SFP is operational. Values are True and False Configuring Port and VLAN Mirroring Port mirroring is used on a network switch to send a copy of network packets seen on one switch port, multiple switch ports, or an entire VLAN to a network monitoring connection on another port on the switch. This is commonly used for network appliances that require monitoring of network traffic, such as an intrusiondetection system. A network analyzer connected to the monitoring port processes the data packets for diagnosing, debugging, and performance monitoring. Up to eight sources can be mirrored. This can be any combination of eight individual ports and/or VLANs. Cisco Small Business 200 Series Smart Switch Administration Guide 65
