• Information center
Provides a central repository for system and network information; aggregates all logs, traps,
and debugging information generated by the system and maintains them in the order of
severity; and sends out the network information to multiple channels, based on user-defined
rules
• IEEE 802.1ab link-layer discovery protocol (LLDP)
Advertises and receives management information from adjacent devices on a network,
facilitating easy mapping by network management applications
• Dual flash images
Provides independent primary and secondary operating system files for backup while
upgrading
• Multiple configuration files
Are easily stored with a flash image
L2 switching
• VLAN
Supports up to 4,096 port-based or IEEE 802.1Q-based VLANs; and supports MAC-based
VLANs, protocol-based VLANs, and IP-subnet-based VLANs for added flexibility (Comware v7
only supports port-based VLANs)
• Bridge protocol data unit (BPDU) tunneling
Transmits STP BPDUs transparently, allowing correct tree calculations across service
providers, WANs, or MANs
• GARP VLAN registration protocol
Allows automatic learning and dynamic assignment of VLANs (Comware v5 only)
• Port mirroring
Duplicates port traffic (ingress and egress) to a local or remote monitoring port; and supports
four mirroring groups, with an unlimited number of ports per group
• STP
Supports the standard IEEE 802.1D STP, IEEE 802.1w rapid STP for faster convergence, and
IEEE 802.1s multiple STP
• Internet-group-management protocol (IGMP) and multicast-listener-discovery (MLD) protocol
snooping
Controls and manages the flooding of multicast packets in an L2 network
• IEEE 802.1ad Q-in-Q and selective Q-in-Q
Increase the scalability of an Ethernet network by providing a hierarchical structure; and
connect multiple LANs on a high-speed campus or metro network
• Per-VLAN spanning tree plus
Allows each VLAN to build a separate spanning tree to improve link bandwidth usage in
network environments with multiple VLANs (Comware v5 only)
• Isolation at data-link layer with private VLANs
Provides—through a two-tier VLAN structure—an additional layer of protection, simplifying
network configuration while saving VLAN resources
