High Reliability - HP JG640A Quickspecs

QuickSpecs
Overview
transitions customers from IPv4 to IPv6, supporting connectivity for both protocols
MLD snooping
directs IPv6 multicast traffic to the appropriate interface, preventing traffic flooding
IPv6 ACL/QoS
supports ACL and QoS for IPv6 network traffic
NAT support
NAT traversal
helps ensure that communication between a branch office AP and HP 830 is supported when the branch uses NAT.
Integrated NAT support
replaces the private source IP address with a public address; enables multiple internal addresses to be mapped to the
same public IP address; permits only certain internal IP addresses to be NAT'ed, and provides an Application Layer
Gateway that supports specific application protocols without requiring the NAT platform to be modified.
IEEE 802.3ad Link Aggregation Control Protocol (LACP)
supports a total of 12 (24-port) or 4 trunk groups (8-port) with each group supporting 8 active ports. Ports must be of the
same type (that is, all 100/1000 ports or 10GbE ports).
Performance
Flexible forwarding modes
supports both distributed and centralized forwarding mode; in a wireless network using centralized forwarding, all wireless
traffic is sent to the HP 830 Unified Wired-WLAN Switch for processing; if the distributed mode is configured, authenticated
clients can continue to access local resources in the event that connectivity to the HP 830 Unified Wired-WLAN Switch is lost
Fast roaming
supports Layer 3 roaming and fast roaming, satisfying the most demanding voice service requirements
Flexible forwarding modes
enable distributed and centralized traffic forwarding
centralized forwarding, wireless traffic is sent to the HP 830 for processing. With distributed mode wireless traffic is
dropped off locally. In the event that connectivity to the HP 830 is lost, authenticated clients can continue to access local
resources.
support local drop off or centralization of data traffic
after an HTML authentication using the built-in portal server or IMC portal authentication.
Resiliency and high availability

High reliability

supports N+1 and N+N backup
Layer 2 switching
VLAN support and tagging
supports IEEE 802.1Q with 4,094 simultaneous VLAN IDs
Spanning Tree Protocol (STP)
supports standard IEEE 802.1D STP, IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) for faster convergence, and IEEE 802.1s
Multiple Spanning Tree Protocol (MSTP)
Port mirroring
duplicates port traffic (ingress and egress) to a local or remote monitoring port
Jumbo packet support
supports frame sizes up to 9K byte (switch) and up to 4K byte (controller) to improve the performance of large data transfers
Layer 3 routing
