HP 5200zl Layer 2 switching, Bridging protocols, Routing protocols, IPv6, Multicast protocols

Layer 2 switching

•HP ProCurve switch meshing: dynamically load-balances across multiple active redundant links to increase available aggregate bandwidth

•VLAN support and tagging: support for complete 802.1Q standard and 2,048 VLANs simultaneously

•802.1v protocol VLANs: isolate select non-IPv4 protocols automatically into their own VLANs

•GVRP: Group VLAN Registration Protocol allows automatic learning and dynamic assignment of VLANs

•Q-in-Q: increases the scalability of Ethernet network by providing a hierarchical structure; connects multiple LANs on high-speed campus or metro Ethernet network

Bridging protocols

•MSTP: provides high link availability in multiple VLAN environments by allowing multiple spanning trees; encompasses 802.1D STP and 802.1w RSTP

Routing protocols

•RIP (v1, v2, and v1-compatible v2)

•OSPF with host-based ECMP (Equal Cost Multi-Path) and NSSA

•Static IP route: to manually add routes directly to the routing table; includes ECMP

•10,000 network address routes, 65,536 L3 host address routes

•UDP helper function: UDP broadcasts can be directed across router interfaces to specific IP unicast or subnet broadcast addresses and prevent server spoofing for UDP services such as DHCP

•Loopback interface address: defines an interface in RIP and OSPF that can always be reachable, improving diagnostic capability

•IPv4 routing

IPv6

•IPv6 host: switches can be deployed and managed at the edge of IPv6 LAN

•IPv4/IPv6 Dual Stack: provides transition mechanism for IPv4 and IPv6

•IPv6 ACL: provides control and security in an IPv6 network

•IPv6 QoS: prioritizes network traffic and enhance performance of applications on the network

•MLD Snooping: prevents multicast traffic from flooding the network

Multicast protocols

•IGMP data-driven

•PIM-SM, PIM-DM

High availability and redundancy

•VRRP: Virtual Router Redundancy Protocol (requires Premium License) allows groups of two routers to dynamically back each other up to create highly available routed environments

•802.3ad LACP: Link Aggregation Control Protocol and HP ProCurve trunking support up to 36 trunks, each with up to 8 links (ports) per trunk

•Port trunks, or link aggregation groups, can operate across multiple modules to increase redundancy.

•Supports various redundant power supply configurations:

–The 5406zl switch provides slots for two internal supplies. This can provide 1+1 redundancy for both PoE and system power needs.

–The 5412zl switch provides slots for four internal supplies. This can provide 1+1 redundancy similar to the 5406zl switch. You can use the internal supplies for 1+1 backup; two backing up two for both PoE and system power needs.

•Hot-swappable/Hot-insertable line interface modules, so as not to interrupt network operation

•Management module is removable/upgradable: The switch does not have to be powered off to remove a management module from a 5400zl series. However, when the management module is removed, all ports will lose communication and the system will be powered down.
