Features and benefits
Quality of Service (QoS)
•
Layer 2/3/4 QoS mechanisms: IEEE 802.1p
marking, precedence, and DiffServ priority tagging
based on IP address, IP Type of Service (ToS), L3
protocol, TCP/UDP port number, and source port
•
QoS maps on Ethernet interfaces: map IEEE
802.1p marking to Layer 3 QoS tag based on ACL
settings
•
Scheduling mechanisms: supports Weighted
Fair Queuing (WFQ), FIFO, Low Latency Queuing
(LLQ), and Priority Queuing (PQ)
•
Class-Based Weighted Fair Queuing
(CBWFQ): allows allocation of bandwidth to a
particular class of traffic based on a percentage of
total available bandwidth or maximum kbps
throughput
•
Traffic shaping and QoS support for
Ethernet ports: allow the ability to apply WFQ,
LLQ, and CBWFQ mechanisms to Ethernet ports
based on DiffServ Code Point settings
•
Policy and shaping: support Frame Relay Traffic
Shaping (FRTS) and Frame Relay Fragmentation
(FRF.12) to help reduce insertion delay across
low-speed WAN links
Resiliency and high availability
•
Equal-cost multi-path (ECMP) for BGP,
OSPF, and static routes: provides the ability to
load-balance traffic across multiple WAN
connections
•
Multilink capability: MLFR and MLPPP enable
multiple T1/E1 ports to be aggregated and
dynamically load-balanced across Frame Relay or
PPP links
•
Multi-homing BGP support: supports redundant
WAN connections to multiple service providers
using BGP routing protocol
•
Network monitor: Provides performance testing
and Layer 3 network connectivity monitoring for
integrated IP interfaces and externally connected
ADSL/cable modems; can be used to initiate a
demand routing backup connection based on the
status of IP links
•
Optional redundant power supply: provides
uninterrupted power (provided by HP E600
RPS/EPS)
Layer 2 switching
•
VLAN support and tagging: support complete
IEEE 802.1Q (4,096 VLAN IDs)
Layer 3 services
•
IP multicast: supports PIM SM, IGMPv2, and
multicast stub routing
•
PIM Sparse mode: routes IP multicast traffic using
PIM Sparse mode (PIM-SM)
•
DHCP support: acts as a DHCP server, relay, or
client
•
SNTP Client/Server:
– SNTP client: obtains time settings from NTP
server using SNTP
– SNTP server: device will respond to SNTP client
requests for time settings
Layer 3 routing
•
IP routing protocols: supports static routes, RIP,
RIPv2, OSPF, and BGP4
•
Policy-based routing: allows users to route
based upon both source and destination address
•
Route redistribution: redistributes routes
between BGP, OSPF, RIP, and static routes
•
Concurrent bridging and routing:
simultaneously bridge non-IP traffic and route IP
traffic on the same interface
•
VLAN-aware bridging: ability to preserve IEEE
802.1Q tag across Frame Relay, PPP, and HDLC
WAN circuits
Standards
•
WAN protocols: provides support for PPP, Frame
Relay, IPSec, HDLC, DDR, MLPPP, MLFR, PPPoA,
and PPPoE
•
Dial-on-Demand Routing (DDR): ISDN or
analog modem links activate when interesting traffic
needs to be routed, helping to avoid costs
associated with toll charges
•
Channelized T1/E1 support: enables
connections of up to 24 or 30 locations at 64 kbps,
terminating on a single T1 or E1 WAN port on the
8xT1/E1 module
