Port Configuration


This command is used to modify port settings on the switch.

Syntax   port-config-modify

port port-list

Specify a single port or a list of ports.

Note: If more than one port is specified, the list must be comma-separated without spaces.

Specify any of the following options:

intf intf-number

Specify a physical interface for the port.

speed disable|10m|100m|1g|

Specify the port speed. Ports configured for speeds of 1G must be equipped with SFP transceivers. Ports configured for 10G or higher must be equipped with SFP+ or QSFP+ transceivers.

bw-bps bw-bps-number 

Specify the bandwidth bps for the port.

egress-rate-limit unlimited

Specify an egress rate limit for the port.

eth-mode 1000base-x|sgmii

Specify the Ethernet mode as 1000 base or Serial Gigabit Media Independent Interface (SGMII).


Specify if the port auto-negotiates the port speed with a peer.


Specify if the port forwards jumbo frames. Jumbo frames are Ethernet frames with more than 1500 bytes of payload.


Specify if the port is enabled and forwards or drops frames.

lacp-priority integer

Specify the LACP priority for the port. If you specify a low value for the priority, the port has a higher priority. This is a value between 1 and 65535.


Specify if the port reflects frames received for loopback testing.


Specify if the port connects to another Pluribus Networks device or is an uplink to a third-party switch or host.


Specify if you want to pause traffic on the port.

description description-string

Specify a description for the port.


Specify to use loopback or no loopback.


Specify if a VXLAN terminates on a port.


Specify if the port receives mirrored traffic only.

port-mac-address mac-address 

Specify the MAC address for the physical port.

loop-vlans vlan-list

Specifies VLANs that are looping on the network.

send-port send-port-number

Specify the port to send traffic.


Specify if the port is participating in routing on the switch.


Specify if you want host-facing ports enabled or disabled.


Specify if you want CRC checking performed by the port. This is applicable to a switch in Virtual Wire mode. The default value is crc-check-disable.

dscp-map dscp-map name | none

Specify a DSCP map name to enable on port.


Specify if local switching is allowed on the port.

allowed-tpid q-in-q|q-in-q-old

Specify the allowed TPID in addition to 0x8100 on VLAN header


Specify if you want loop detection enabled on the port.


Defaults   The default port speed is 10G per second. Autonegotiation and jumbo frames are disabled by default. The port is enabled by default.

Usage   Server-switches are equipped with network data ports for host or inter-switch communication. This command configures the settings of a specific network data port of all data ports on the local switch.

Examples  To configure port 17 on a switch to operate at 1 Gbps without jumbo frames, use the following command:

CLI network-admin@switch > port-config-modify port 17 speed 1G autoneg off jumbo off
