Unified Communications and
Collaboration
Mainstream Unified Communications and
Collaboration applications such as IP telephony and
Voice over IP are providing businesses with more
cost-effective ways to serve end users and enhance
IT productivity. With advanced high-availability
features like Nonstop Switching, the 8200zl switch
series helps ensure that converged traffic flows are
delivered with the highest levels of availability. Built
on this foundation, the 8200zl series provides a wide
range of Unified Communications and Collaboration
protocols and tools:
•Multicast support via data-driven IGMP, PIM Dense,
and PIM Sparse
•Advanced QoS, including eight hardware priority
queues and selectable queue configuration; set
and enforce prioritization based on multiple match
criteria such as Layer 2 (IEEE 802.1p, VLAN ID),
Layer 3 (DSCP, IP address), and Layer 4 (TCP/UDP
port) markings
•Bandwidth shaping by enforcing ingress/egress
maximum and egress guaranteed minimum
bandwidths
•Support for IP telephony through interoperability
with industry-leading IP telephony vendor products;
LLDP-MED, which enables automatic configuration
of QoS and VLAN; RADIUS VLAN, which uses a
standard RADIUS attribute to automatically configure
VLAN for IP phones; and IEEE 802.3af PoE, 802.3at
PoE+, and prestandard PoE support
•PoE management tools for intelligent power
allocation and redundancy for efficient power usage
and enhanced availability
Mobility
In the context of a highly scaled wireless network
topology, the 8200zl switch series provides the
foundation of robust, reliable core switching to meet
end-user requirements for anytime, anywhere access:
•Support for highly scalable, centralized core or
distribution-layer wireless access management and
security with the HP ProCurve MSM765zl Mobility
Controller
•Support for WLAN access points as well as IEEE
802.3af and prestandard PoE/PoE+ support
•PoE or PoE+ standard on all Gigabit copper ports
to provide deployment flexibility and allow for
selective integration of wireless access points without
additional cost or overhead
•Unified wired/wireless client and network
management to provide both end users and network
administrators with a consistent user experience
no matter where and over what infrastructure
connections are made
•Web Auth to provide flexible authentication
for mobile workers to connect securely to
network resources
