NetVisor OS Command Reference 7.0.2

optimize-arps|no-optimize-arps

Enable or disable ARP optimization. This feature is ON by default. When ON, the NetVisor OS sends all ARP requests, and Gratuitous ARP requests to the local CPU of the corresponding switch, and responds to ARP requests on behalf of the intended ARP targets. This feature corresponds to an ARP-proxy function on the corresponding switch. It is assumed that ARP requests, and Gratuitous ARP requests are used by NetVisor OS to learn the MAC address to IPv4 address mapping, as well as Unknown Unicast, and Broadcast traffic when The parameters manage-unknown-unicast or manage-broadcast are ON. When OFF, the NetVisor learns, and bridges ARP requests on the switch ASIC instead of relying on the local CPU.

lldp|no-lldp

Enable or disable LLDP discovery.

policy-based-routing|no-policy-based-routing

Enable or disable policy-based routing.

optimize-nd|no-optimize-nd

Enable or disable Neighbor Discovery optimization. This feature is ON by default. When ON, NetVisor OS sends all Neighbor Solicitations, and Unsolicited Neighbor Advertisements to the local CPU of the corresponding switch, responds to Neighbor Solicitation requests on behalf of the intended ND targets themselves. This feature corresponds to an ND-proxy function on the corresponding switch. Neighbor Solicitations, and Unsolicited Neighbor Advertisements are used by NetVisor OS to learn the MAC address to IPv6 address mapping, as well as Unknown Unicast, and Broadcast traffic when tThe parameters manage-unknown-unicast or manage-broadcast are ON. When OFF, the NetVisor learns, and bridges Neighbor Solicitations on the switch ASIC instead of relying on NetVisor OS.

reactivate-mac|no-reactivate-mac

Enable or disable reactivation of aged out MAC entries. This feature is ON by default. When ON, if a vPort entry is looked up, and found as inactive, the corresponding l2-table entry is re-activated on the switch. When OFF, the traffic is flooded on the corresponding broadcast domain by theNetVisor OS. Please note that l2-table entries are refreshed on the Ethernet switch ASIC every time it is used, otherwise it is removed after a time of inactivity corresponding to configured aging period. Requires unknown-unicast to be enabled.

reactivate-vxlan-tunnel-mac|no-reactivate-vxlan-tunnel-mac

Enable or disable enable reactivation of MAC entries over VXLAN tunnels.

manage-unknown-unicast|no-manage-unknown-unicast

Enable or disable unknown unicast management. This feature is ON by default. NetVisor sends all unknown-unicast traffic to the local CPU of the corresponding switch. NetVisor learns the source of unknown-unicast packets, and floods the packets on the corresponding unknown-unicast domain. When OFF, all unknown-unicast traffic is flooded on the corresponding unknown-unicast domain by the switch instead of relying on NetVisor OS.

manage-broadcast|no-manage-broadcast

Enable or disable broadcast management. This feature is ON by default. NetVisor sends all broadcast traffic to the local CPU of the corresponding switch. NetVisor learns the source of broadcast packets, and floods the packets on the corresponding broadcast domain. When OFF, all unicast traffic is flooded on the corresponding broadcast domain by the switch instead of relying on NetVisor OS.

manage-wake-on-lan|no-manage-wake-on-lan        

Enable wake-on-lan management.

and data traffic.

The default value is all.

cpu-class-enable|no-cpu-class-enable
