Switch Redundancy - HP 445860-B21 - 10Gb Ethernet BL-c Switch User Manual

•
Support for Telnet, SNMP, SCP, FTP, and TFTP file transfer, human read/write configuration file,
XModem, and an extensive list of MIB objects further enhance the management capabilities
•
Fully redundant end-to-end architecture maximizing server availability from the network
•
Support for IGMP snooping for multicasting
•
Support for UFD for network path resiliency. It works in conjunction with NIC teaming functionality
that is supported on the blade servers. This feature tracks the link state on uplink ports. When an
uplink port goes down or is in STP blocking state, this feature will enable the switch to auto disable
the downlinks which are connected to the blade server NICs. This enables NIC teaming software to
detect link failure on the primary NIC port and fail over to the secondary NIC in the team. As a
result, the secondary path is enabled for continued blade server access.
When used in conjunction with UFD, NIC teams on the blade server must be configured for switch
redundancy. That is, the team will span ports on both Switch 1 and Switch 2. See the HP network
adapter teaming: load balancing in ProLiant servers running Microsoft Windows operating systems
white paper for additional information. To locate this white paper:
Go to the HP website (http://www.hp.com/support).

•
RMON feature, which allows network devices to exchange network monitoring data. RMON
performs these major functions:
Gathers cumulative statistics for Ethernet interfaces
o
Tracks a history of statistics for Ethernet interfaces
o
Creates and triggers alarms for user-defined events
o
•
An administrator can define end user accounts that permit limited access to the switch. The switch
requires username/password authentication for end users.
•
Fast Uplink Convergence that enables the switch to quickly recover from the failure of the primary
link or trunk group in a Layer 2 network using Spanning Tree Protocol.
•
Support for SSH version 2. SSH is a protocol that enables remote administrators to log securely into
the switch over a network to execute management commands.
•
Switch software provides SNMP support for access through any network management software, such
as HP OpenView.
•
Support for HTTP software upgrade using the BBI. FTP or TFTP server is not required to perform a
software upgrade.
•
Port Fast Forwarding that allows a port that participates in Spanning Tree to bypass the Listening and
Learning states and enter directly into the Forwarding state.
•
Allows secure browser access (HTTPS) to management functions

Switch redundancy

In a dual switch configuration, the switches offer several redundancy and failover features. With these
features, the network configuration is designed to allow for continued network access to each server
blade in case of a component or link failure. The switch redundancy and failover features include:
