NETGEAR 8800 Chassis Switch CLI Manual • System location (optional)-Using the system location field, you can find the location of the switch. Note: If you specify volatile storage when configuring SNMP parameters, that configuration is not saved across a switch reboot. Telnet Telnet allows you to access the switch remotely using TCP/IP through one of the switch ports or a workstation with a Telnet facility. If you access the switch via Telnet, you will use the command line interface (CLI) to manage the switch and modify switch configurations. TFTP NETGEAR 8800 supports the Trivial File Transfer Protocol (TFTP) based on RFC 1350. TFTP is a method used to transfer files from one network device to another. The NETGEAR 8800 TFTP client is a command line application used to contact an external TFTP server on the network. For example, the NETGEAR 8800 uses TFTP to download software image files, switch configuration files, and access control lists (ACLs) from a server on the network to the switch. System Redundancy with Dual Management Modules Installed If you install two MSMs/MMs, one assumes the role of primary and the other assumes the role of backup. The primary MSM/MM provides all of the switch management functions including bringing up and programming the I/O modules, running the bridging and routing protocols, and configuring the switch. The primary also keeps synchronized with the backup MSM/MM in case the backup MSM/MM needs to take over the management functions if the primary MSM/MM fails. Power Supply Management On the NETGEAR 8800, the 8800 OS monitors and manages power consumption on the switch by periodically checking the power supply units (PSUs) and testing them for failures. To determine the health of the PSU, the 8800 OS checks the voltage, current, and temperature of the PSU. The power management capability of the NETGEAR 8800 OS: • Protects the system from overload conditions. 58 | Chapter 3. Commands for Managing the Switch
