system-settings-modify

This command allows you to modify system settings to optimize Netvisor performance.

Syntax   system-settings-modify

optimize-arps|no-optimize-arps

Enable or disable ARP optimization. This feature is ON by default. When ON, the Netvisor 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 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 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 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, theNetvisor learns and bridges Neighbor Solicitations on the switch ASIC instead of relying on Netvisor.

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. 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.

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.

block-loops|no-block-loops

Enable or disable loop blocking.

auto-trunk|no-auto-trunk

Enable or disable auto trunking.

auto-host-bundle|no-auto-host-bundle

Enable or disable host auto bundling.

routing-over-vlags|
no-routing-over-vlags

Enable or disable routing to VLAGs from cluster links.

cluster-active-active-routing|
no-cluster-active-active-routing

Enable or disable active-active cluster routing.

optimize-datapath disable|cluster-only|all

Optimize the datapath on ONVL switches with no rear-facing NIC.

source-mac-miss to-cpu|copy-to-cpu

Control unknown source MAC address learn behavior.

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

Enable or disable CPU class.

use-igmp-snoop-l2|use-igmp-snoop-l3

Use Layer 2 or Layer 3 tables for IGMP snooping.

vle-tracking-timeout seconds

Specify VLE tracking timeout in seconds from 3 to 30 seconds.

usb|no-usb

Enable or disable the USB port on the front of the switch. This is only applicable to switches with ONVL.

cosq-weight-auto|no-cosq-weight-auto

Specify if you want to adjust queue weights automatically.

lossless-mode|no-lossless-mode

Specifies lossless mode.

stagger-queries|
no-stagger-queries

Specify if you want to stagger sending IGMP queries on the network.

host-refresh|no-host-refresh

Specify if you want to enable refreshing host ARP entries to keep L2 entries active.

proxy-conn-retry|no-proxy-conn-retry

Enable or disable proxy connection retry.

proxy-conn-max-retry integer

Specify the maximum number of proxy connection retry attempts from 0 to 20.

proxy-conn-retry-interval mseconds

Specify the number of milliseconds, from 100 to 2000,   to wait between proxy connection retry attempts.

   

Defaults   All parameters enabled by default.

Access   Network Administrator

Usage   Use this command to enable or disable system settings. However, it is recommended that you do not modify the settings without consulting Pluribus Networks.

Examples  To disable auto-trunking, use the following syntax:

CLI network-admin@switch > system-settings-modify no-auto-trunk
