Features and benefits
Quality of Service (QoS)
•
Traffic prioritization (IEEE 802.1p): allows
real-time traffic classification into eight priority levels
mapped to eight queues
•
Class of Service (CoS): sets the IEEE 802.1p
priority tag based on IP address, IP Type of Service
(ToS), Layer 3 protocol, TCP/UDP port number,
source port, and DiffServ
•
Rate limiting: sets per-port ingress enforced
maximums and per-port, per-queue guaranteed
minimums
•
Bandwidth shaping:
– Rate limiting: provides per-port, ingress-based
enforced bandwidth maximums
– Guaranteed minimums: provides per-port,
per-queue egress-based guaranteed bandwidth
minimums
Management
•
Secure Web GUI: provides a secure, easy-to-use
graphical interface for configuring the module via
HTTPS
•
Command-line interface (CLI): provides a
secure, easy-to-use command-line interface for
configuring the module via SSH or a switch console;
provides direct real-time session visibility
•
SNMPv1, v2c, and v3: facilitate centralized
discovery, monitoring, and secure management of
networking devices
•
3Com-heritage Comware V3 Operating
System: CLI and Web user interface in common
with HP E4XXX and E55XX series switches
•
Port mirroring: enables traffic on a port to be
simultaneously sent to a network analyzer for
monitoring
Connectivity
•
Auto-MDIX: automatically adjusts for
straight-through or crossover cables on all 10/100
ports
•
IEEE 802.3af Power over Ethernet (PoE):
provides up to 15.4 W per port to IEEE
802.3af-compliant PoE-powered devices such as IP
phones, wireless access points, and security
cameras
•
Gigabit uplinks: dual-personality ports for either
10/100/1000 or mini-GBIC SFP connectivity for
increased connectivity flexibility
Manageability
•
RMON (remote monitoring): provides
advanced monitoring and reporting capabilities for
statistics, history, alarms, and events
•
Dual flash images: provides independent
primary and secondary operating system files for
backup while upgrading
•
Full-featured console: provides complete control
of the switch with a familiar command-line interface
(CLI)
•
Web interface: allows configuration of the switch
from any Web browser on the network
•
Multiple configuration files: allow multiple
configuration files to be stored to flash image
•
Software updates: free downloads from the
Web
•
Advanced stacking: locally connect up to eight
E5500 switches using Gigabit ports and manage as
a single entity; improves resiliency by spreading
aggregated links across multiple stacked units
•
Virtual stacking capability: single IP address
management for a virtual stack of up to 255
Comware-based 3Com legacy devices, including
HP E4XXX and E55XX series switches
Layer 2 switching
•
VLAN support and tagging: support IEEE
802.1Q, with 4094 simultaneous VLAN IDs
•
GARP VLAN Registration Protocol (GVRP):
allows automatic learning and dynamic assignment
of VLANs
•
Jumbo packet support: supports up to
9220-byte frame size to improve performance of
large data transfers
•
IEEE 802.1ad QinQ: increases the scalability of
an Ethernet network by providing a hierarchical
structure; connects multiple LANs on a high-speed
campus or metro network
Layer 3 routing
•
Layer 3 IP routing: provides routing of IP at
media speed; supports static routes, RIP, RIPv2, and
OSPF
•
OSPF-ECMP (Equal-Cost Multipath): enables
multiple equal-cost links in OSPF environment to
increase link redundancy and scale bandwidth
