This includes the detection of full duplex for
servers and other switches and half-duplex legacy
systems and hubs.
• Security: BaySecure prevents unauthorised access
to the switches and the network infrastructure.
Features and Benefits
• Scalability - BayStack 450 stacks up to 8 units
providing up to 224 10/100 ports and the entire
stack can be managed as a single entity via a
single IP address providing ease of network
management. Also when stacked with BPS, it can
be managed via the Web, thus giving network
administrators the flexibility of management
interfaces.
• Distributed Multi Link Trunking - MultiLink
Trunking across different switches in a stack is
another key differentiation for the BayStack 450
Switches by providing high bandwidth and fault
tolerance. Aggregating ports from more than one
switch in a stack with Distributed MultiLink
Trunking can provide fail-over protection to
important network devices and servers.
LinkSafe redundant PHYs (physical connectors)
offer another way to stay connected to the
network centre, even if a cable or connector
should fail. Note how these features are
paralleled with Passport Routing Switches
features, making for an integrated
switching solution.
• FailSafe Stackability - A key differentiation for the
BayStack 450 Switches is their fail-safe stacking
feature. BayStack 450 Switches can stack up to 8
units with a cascade stacking design,
guaranteeing uptime even if any switch in the
stack should fail. Cascade cables loop stacking
signals back at point of failure, thus maintaining
the integrity of the stack, even in the unlikely
event of a switch unit failure.

• Line-rate IP Multicast Pruning
(IGMP Snooping)
• Distributed MultiLink Trunking across
the stack
• Broadcast/Multicast Rate Limiting
• 16,000 MAC addresses
• 64 port-based VLANs
• Protocol-based VLANs
• Port Mirroring
• 4 RMON groups per port
• Recovery configuration file support
• Supports 802.3x flow control on Gigabit ports
• Web-based management and security features*
• Full integration into Optivity
*Baystack 450 can be managed via the web when stacked
with the Business Policy Switch
Advanced software features of the BayStack 450
switch make it an ideal solution for the enterprise
looking for performance, guaranteed 24/7 network
availability, a range of uplink options and
redundancy for mission critical applications.
