Data sheet | HP 10500 Switch Series

• 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
