4

Resiliency and high availability
• Backup center

Acts as a part of the management and backup function to provide backup for device
interfaces; delivers reliability by switching traffic over to a backup interface when the primary
one fails

• External redundant power supply

Provides high reliability

• Virtual Router Redundancy Protocol (VRRP)

Allows groups of two routers to back each other up dynamically to create highly available
routed environments; supports VRRP load balancing

Layer 2 switching
• 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)

• Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) protocol

snooping

Control and manage 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 up to 4,094 port or IEEE 802.1Q-based VLANs

• sFlow

Allows traffic sampling

Layer 3 services
• 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

Layer 3 routing
• Static IPv4 routing

Provides simple manually configured IPv4 routing

• Routing Information Protocol (RIP)

Uses a distance vector algorithm with UDP packets for route determination; supports RIPv1
and RIPv2 routing; includes loop protection

• Border Gateway Protocol 4 (BGP-4)

Delivers an implementation of the Exterior Gateway Protocol (EGP) utilizing path vectors; uses
TCP for enhanced reliability for the route discovery process; reduces bandwidth consumption
by advertising only incremental updates; supports extensive policies for increased flexibility;
scales to very large networks
