HP ProCurve Switch 8212zl

• IEEE 802.3ad Link Aggregation Control Protocol (LACP) and

ProCurve trunking: support up to 60 trunks, each with up to 8

links (ports) per trunk; trunking across modules is supported

• Hot-swappable modules: interface, management, and fabric

modules as well as mini-GBIC optics and power supplies can be

removed, swapped, or added to the system without interrupting

ongoing switch operations

• Redundant, scalable power design: add/deploy redundant

power supplies to expand power capacity and provide redundancy

to ensure network productivity

• Redundant switch fabric: dual, performance load-sharing fabric

modules provide enhanced system availability and seamless

system resiliency

• Redundant switch management: dual management modules

provide active/standby operation to enhance system availability

• Redundant, hot-swappable cooling: redundant fan design and

hot-swappable fan tray ensure continuity of operation in case of a

single fan failure

• Passive system design: passive chassis backplane (no

traffic-forwarding active componentry) ensures system reliability

and reduces impact of component failure

Layer 2 switching

IEEE 802.1ad Q-in-Q: increases the scalability of Ethernet

NEW

network by providing a hierarchical structure; connects multiple

LANs on high-speed campus or metro network

• ProCurve switch meshing: dynamically load-balances across

multiple active redundant links to increase available aggregate

bandwidth

• VLAN support and tagging: supports the IEEE 802.1Q

standard and 2,048 VLANs simultaneously

• IEEE 802.1v protocol VLANs: isolate select non-IPv4 protocols

automatically into their own VLANs

• GARP VLAN Registration Protocol: allows automatic learning

and dynamic assignment of VLANs

Layer 3 services

• 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 address in RIP and

OSPF that can always be reachable, improving diagnostic

capability

Layer 3 routing

• Static IP routing: provides manually configured routing; includes

ECMP capability

• RIP: provides RIPv1 and RIPv2 routing

• OSPF: includes host-based ECMP to provide link

redundancy/scalable bandwidth and NSSA

Security

• Switch CPU protection: provides automatic protection against

malicious network traffic trying to shut down the switch

• Virus throttling: detects traffic patterns typical of WORM-type

viruses and either throttles or entirely prevents the ability of the

virus to spread across the routed VLANs or bridged interfaces,

without requiring external appliances

• ICMP throttling: defeats ICMP denial-of-service attacks by

enabling any switch port to automatically throttle ICMP traffic

• Multiple user authentication methods:

- IEEE 802.1X: industry-standard way of user authentication using

an IEEE 802.1X supplicant on the client in conjunction with a

RADIUS server

- Web-based authentication: authenticates from Web browser

for clients that do not support 802.1X supplicant; customized

remediation can be processed on an external Web server

- MAC-based authentication: client is authenticated with the

RADIUS server based on client's MAC address

• Authentication flexibility:

- Multiple IEEE 802.1X users per port: provides authentication of

multiple IEEE 802.1X users per port; prevents user "piggybacking"

on another user's IEEE 802.1X authentication

- Concurrent IEEE 802.1X, Web, and MAC authentication

schemes per port: switch port will accept up to 32 sessions of

IEEE 802.1X, Web, and MAC authentications

• Access control lists (ACLs): provide filtering based on the IP

field, source/destination IP address/subnet, and source/destination

TCP/UDP port number on a per-VLAN or per-port basis

• Identity-driven ACL: enables implementation of a highly

granular and flexible access security policy and VLAN assignment

specific to each authenticated network user

• DHCP protection: blocks DHCP packets from unauthorized

DHCP servers, preventing denial-of-service attacks

• STP BPDU port protection: blocks Bridge Protocol Data Units

(BPDUs) on ports that do not require BPDUs, preventing forged

BPDU attacks

• Dynamic IP lockdown: works with DHCP protection to block

traffic from unauthorized hosts, preventing IP source address

spoofing
