Introduction 7 • 9K jumbo frames that improve performance by in creasing application throughput and decreasing server processor utilization • Robust configuration and management from any sw itch port using the inc luded b rowser-based and scriptable command line user interfaces. • Support for Telnet, SNMP, SCP, FTP, and TFTP fi le transfer, h[...]

Introduction 8 Switch redundancy In a dual switch configuration, th e switch es offer several redundancy and failover features. Wit h these features, the networ k configuration is desi gned to allow for continued network access to each server blade in case of a component or link failure. The switch redundanc y and failover features incl ude: • Up[...]

Introduction 9 • A text-based, human read/write configuration fi le provides viewing, printing, and editing capabilities. • A DNS client supports primary and secondary DNS servers. • Any port can be enabled or disabled as desired. • Any switch port can be used to perform switch management and PXE. Diagnostic tools The hardware, software, an[...]

Introduction 10 ten Gigabit external Ethernet ports and sixteen internal Gigabit Ethernet ports providing connectivity to the blade servers within the enclosure. Redundant crosslinks In a dual switch configuration, the two switches are connected through a single te n gigabit crosslink. This crosslink prov ides throughput of ten Gb/s for traffic bet[...]

Introduction 11 • High availability VRRP Layer 3 switching provides more powe r, flexibility, and security capabi lities to network administrators. Network traffic is managed much mo re efficiently and broadcast traffi c between servers remains within the enclosure. Security features provide added protection for switch configuration data, while p[...]

Introduction 12 are members of a specific IP networ k. This is achieved by configurin g the address/mask of that specific network as a restricted mana gement network address/mask. Port mirroring The switch allows mirroring of one or multiple ports (source ports) to another port (destination port) for network monitoring and troublesh ooting purposes[...]

Introduction 13 RADIUS The switch supports the RADIUS method to authentica te and authorize remote administrators for managing the switch. This method is based on a client/server mo del. The RAS, the switch, is a client to the bac k-end database server. A remote user (the remote administrator) interacts only with the RAS, not the back-end server an[...]

Introduction 14 • The accounting attrib utes of pr otocol, start_time, stop_time, an d elapsed_time. For BBI users, accounting stop reco rds are only sent if the user presses the QUIT button. SSH and SCP SSH and SCP use secure tunnels to enc rypt and secu re messages between a rem o te administrator and the switch. Telnet does not prov ide this l[...]

Introduction 15 through a procedure called auto-negotiation. Auto-neg otiation involves probing the capability of the network using low-level sign aling tech niques to select compatible Ethe rnet speeds . Auto-negotiation was originally developed to make the migration from traditional Ethernet to Fast Ethernet products easier. Redundant images in f[...]
