• The switch does not support tunnel interfaces for unicast routed traffic. • The number of routed ports and SVIs that you can configure is 2000. Exceeding the recommended number and volume of features being implemented might impact CPU utilization because of hardware limitations. • Subnetwork Access Protocol (SNAP) address resolution is not supported on this device. Information About IP Unicast Routing This module describes how to configure IP Version 4 (IPv4) unicast routing on the switch.
Note In addition to IPv4 traffic, you can also enable IP Version 6 (IPv6) unicast routing and configure interfaces to forward IPv6 traffic if the switch or switch stack is running the Network Essentials or Network Advantage license. Configuring IP Unicast Routing 1
