900-48
| Enhanced Fast Ethernet Layer 3+ Switch
Key Features
Performance
•
Layer 2 and 3 IPv4 switching and routing all
at wire-speed
•
37.6Gbps switch fabric yielding 13.1 Million
packets per second performance
•
Provides up to 256K Layer 3 address table
entries
•
Supports full 4096 VLANS with VLAN
double tagging
•
Private VLANs, providing security and port
isolation of multiple customers using the
same VLAN
•
Supports 4096 Layer 3 interfaces
•
Gigabit SFP ports will support any
combination of 1000BASE-T, 1000BASE-SX,
1000BASE-LX or 1000BASE-ZX SFPs
•
Extensive wire-speed traffic classification for
ACLs and QoS
•
Advanced routing protocols OSPF, BGP4,
RIP and RIPv2, DVMRP, PIM-SM, PIM-DM
•
Full IPv4 and IPv6 routing
•
Wire-speed multicasting
•
Supports equal cost multi path (ECMP)
routing in hardware
Availability
•
1RU form factor, high port density and front
to back cooling, ideal for high density rack
and wiring closet installations
•
Internal dual hot-swappable AC or DC load-
sharing power supplies remove the need for
an expensive and rack space wasting
redundant power supply (RPS)
•
Full environmental monitoring of PSUs, fans,
temperature and internal voltages, with
SNMP traps to alert network managers in
case of any failure
Quality of Service (QoS)
•
Policy based QoS features
•
Highly configurable traffic classification
•
Extensive remarking capabilities, to fit in
with any network's QoS scheme
•
Control plane traffic prioritization
•
Mixed scheduling, to support complex traffic
queuing requirements
•
8 QoS queues per port
•
Two-rate three-color (green, yellow, red)
bandwidth metering, with burst sizes for
improved TCP-IP bandwidth limiting
performance and bandwidth resolution
down to 1Kbps
•
Low switching latency essential for Voice
over IP (VoIP) and real-time streaming
media applications
Resiliency
•
MSTP (802.1s)
•
SNMP MIB to monitor QoS traffic counters
•
DHCP Snooping
•
DHCP Option 82
•
Management stacking
•
EPSR
•
Port trunking (802.3ad LACP)
Management
•
Asynchronous management port on the
front panel for ease of access
•
A CompactFlash port, accessible via the
front panel, enables configurations and other
files to be saved or transferred between
switches
•
Port mirroring
•
SSH and SNMPv3 for secure management
•
SNMPv3 with extensive MIB support
•
802.1x support
•
