EtherWAN’s Layer 3 switches can make routing decisions based on IP addresses, with support for both static routes and RIP v1/v2 protocols. Additionally, these switch support Virtual Router Redundancy Protocol (VRRP), which increases the availability and reliability of routing paths on an IP subnetwork. All lite Layer 3 switches support SNMP, port mirroring, QoS, flow control, VLANs, Link Aggregation, IGMP snooping, DHCP, and DDM. With rugged construction and hardened specifications, they can withstand temperatures from -40 to 75°C (-40 to 167°F). Some lite Layer 3 switches are also PoE enabled, for convenient and economical powering of remote devices.
