Routing Features
Address Resolution Protocol (ARP) Table Management
Static ARP entries can be created, and many settings for the dynamic ARP
table can be managed, such as age time for entries, retries, and cache size.
The ARP table supports routing by caching MAC addresses corresponding to
the IP addresses of attached stations.
For information about managing the ARP table, see "IP Routing" on
page 1113.
VLAN Routing
Dell EMC Networking N-Series switches support VLAN routing. A VLAN-
routed packet is routed based on a longest prefix match lookup of the
destination IP address in the routing table and is forwarded on a different
VLAN by rewriting the destination MAC address obtained from the ARP
table, decrementing the TTL, recalculating the frame CRC, and transmitting
the frame on the VLAN.
For information about configuring VLAN routing interfaces, see "Routing
Interfaces" on page 1139.
IP Configuration
The switch IP configuration settings allow the configuration of network
information for VLAN routing interfaces, such as the IP address and subnet
mask. Global IP configuration settings for the switch allow enabling or
disabling the generation of several types of ICMP messages, setting a default
gateway, and enabling or disabling inter-VLAN routing of packets.
For information about managing global IP settings, see "IP Routing" on
page 1113.
NOTE: The N1100-ON Series switches do not support routing.
