J8772B - HP ProCurve Switch 4204vl-72

Description

Dual flash images

Provides independent primary and secondary operating system files for backup while upgrading.

Multiple configuration files

Allows a configuration file to be stored to flash image.

Friendly port names

Allow assignment of descriptive names to ports.

Find-fix-inform

Finds and fixes common network problems automatically, then informs administrator.

Troubleshooting

Ingress and egress port monitoring enable network problem solving.

RMON and XRMON

Provide advanced monitoring and reporting capabilities for statistics, history, alarms, and events.

Traffic prioritization (IEEE 802.1p)

Allows real-time traffic classification into eight priority levels mapped to eight queues.

Class of Service (CoS)

Sets the IEEE 802.1p priority tag based on IP address, IP Type of Service (ToS), Layer 3 protocol, TCP/UDP port number, source port, and DiffServ.

Uni-Directional Link Detection (UDLD)

Monitors cable between two switches and shuts down the ports on both ends if the cable is broken, turning the bi-directional link into uni-directional; this prevents network problems such as loops.

Architecture

Up to 76.8 Gbps crossbar switching fabric provides wire-speed intra- and inter-module switching with up to 48 million pps throughput built on HPE custom-designed ASIC technology.

IEEE 802.1s multiple spanning tree protocol

Provides high link availability in multiple VLAN environments by allowing multiple spanning trees; encompasses IEEE 802.1D spanning tree protocol and IEEE 802.1w rapid spanning tree protocol.

Hot-swappable modules

Permit modules and mini-GBICs to be added or swapped without interrupting the network.

Multiple IEEE 802.1X users per port

Provides authentication of up to eight IEEE 802.1X users per port; prevents user "piggybacking" on another user's IEEE 802.1X authentication.

Dynamic ARP protection

Blocks ARP broadcasts from unauthorized hosts, preventing eavesdropping or theft of network data.

Secure File Transfer Protocol (FTP)

Allows secure file transfer to and from the switch; protects against unwanted file downloads or unauthorized copying of switch configuration file.

Source-port filtering

Aallows only specified ports to communicate with each other.

Secure Shell (SSHv2)

Encrypts all transmitted data for secure, remote command-line interface (CLI) access over IP networks.

Secure Sockets Layer (SSL)

Encrypts all HTTP traffic, allowing secure access to the browser-based management GUI in the switch.

Switch management logon security

Can require either RADIUS or TACACS+ authentication for secure switch CLI logon.

Custom banner

Displays security policy when users log in to the switch.

STP BPDU port protection

Blocks Bridge Protocol Data Units (BPDUs) on ports that do not require BPDUs, preventing forged BPDU attacks.

IP multicast (data-driven IGMPv3)

Automatically prevents flooding of IP multicast traffic.

LLDP-MED (Media Endpoint Discovery)

It is a standard extension of LLDP that stores values for parameters such as QoS and VLAN to automatically configure network devices such as IP phones.
