The HP A-MSR20-1x Series is a set of full-featured, economical routers designed for converged WAN, wired, and wireless LAN traffic at enterprise branch locations and small to medium-sized businesses. They deliver high performance while reducing complexity, simplifying management, and increasing control. These routers enable an agile and flexible network infrastructure that can quickly adapt to changing business requirements, while delivering integrated, concurrent services on a single, easy-to-manage platform.
- Traffic policing: supports Committed Access Rate (CAR) and line rate
- Congestion management: supports FIFO, PQ, CQ, WFQ, CBQ, and RTPQ
- Congestion avoidance: weighted Random Early Detection (WRED)/RED
- Other QoS technologies: support traffic shaping, FR QoS, MPLS QoS, and MP QoS/LFI
- Industry-standard CLI with a hierarchical structure: reduces training time and expenses, and increases productivity in multivendor installations
- Management security: multiple privilege levels, with password protection, restrict access to critical configuration commands; ACLs provide telnet and SNMP access; local and remote syslog capability allow logging of all access
- SNMPv1, v2, and v3: provides complete support of SNMP; SNMPv3 supports increased security using encryption; provides full support of industry-standard MIBs plus private MIB extensions
- Remote Monitoring (RMON): uses standard SNMP to monitor essential network functions; supports events, alarm, history, and statistics group plus a private alarm extension group
- FTP, TFTP, and SFTP support: File Transfer Protocol allows bi-directional transfers over a TCP/IP network and is used for configuration updates; Trivial FTP is a simpler method using UDP
- Packet storm protection: protects against broadcast, multicast, or unicast storms with user-defined thresholds
- Loopback: supports internal loopback testing for maintenance purposes and an increase in availability; loopback detection protects against incorrect cabling or network configurations and can be enabled on a per-port or per-VLAN basis for added flexibility
- 3G access support: allows use of SIC 3G module for high reliability; supports popular USB 3G modem
- Flexible port selection: provides combination of fiber and copper interface modules, 100/1000Base-X auto-speed selection, and 10/100/1000Base-T auto-speed detection plus auto duplex and MDI/MDI-X
- Multiple WAN interfaces: provide a traditional link with Serial, E1/T1, ADSL, and ISDN/AM backup; provide high-density Ethernet access with WAN Fast Ethernet/Gigabit Ethernet and LAN 4- and 9-port Fast Ethernet; provide mobility access with 11g/n Wi-Fi and 3G
- Powerful encryption capacity: includes embedded hardware encryption accelerator to improve encryption performance
- Flexible chassis selection: offers a choice 12 routers; meets different requirements on enterprise branches
- Excellent forwarding performance: provides forwarding performance up to 160 Kpps; meets today's and future demand for an enterprise organization's bandwidth-intensive applications
- Virtual Router Redundancy Protocol (VRRP): allows a group of routers to dynamically back each other up to create highly available routed environments
- Backup Centre: functions as a part of the management and backup function to provide backup for interfaces on your device; delivers reliability by switching traffic over to a backup interface when the primary one fails
- Spanning Tree: fully supports standard IEEE 802.1D Spanning Tree Protocol, IEEE 802.1w Rapid Spanning Tree Protocol for faster convergence, and IEEE 802.1s Multiple Spanning Tree Protocol
- IGMP and MLD snooping: effectively controls and manages the flooding of multicast packets in a Layer 2 network
- Port mirroring: duplicates port traffic (ingress and egress) to a local or remote monitoring port
- VLANs: support IEEE 802.1Q-based VLANs
- Address Resolution Protocol (ARP): determines the MAC address of another IP host in the same subnet; supports static ARPs; gratuitous ARP allows detection of duplicate IP addresses; proxy ARP allows normal ARP operation between subnets or when subnets are separated by a Layer 2 network
- User Datagram Protocol (UDP) helper: redirects UDP broadcasts to specific IP subnets to prevent server spoofing
- Dynamic Host Configuration Protocol (DHCP): simplifies the management of large IP networks and supports client and server; DHCP Relay enables DHCP operation across subnets
