Dell S4048T User Manual

NOTE: Even after you disable ip-local-proxy-arp (no ip-local-proxy-arp) in a secondary
VLAN, Layer 3 communication may happen between some secondary VLAN hosts, until the address
resolution protocol (ARP) timeout happens on those secondary VLAN hosts.

NOTE: Secondary VLANs are Layer 2 VLANs, so even if they are operationally down while primary VLANs
are operationally up, Layer 3 traffic is still transmitted across secondary VLANs.
NOTE: The outputs of the show arp and show vlan commands provide PVLAN data. For more
information, refer to the Dell Networking OS Command Line Reference Guide.
