Displaying Port Information
The Netvisor ONE CLI features multiple commands that display relevant switch port information including transceiver information, physical-to-logical port mappings, Layer 2 configuration of physical ports.
Use the port-show command to display a host of parameters for all the ports with active links. Information displayed for each port includes the IP addresses and MAC addresses of hosts connected to that port. There can be more than one host per port if a network device such as an external switch is connected to it.
The port-show command also displays port status, VLAN ID, VXLAN ID, and configuration details.

Displaying Port Numbering
Bezel interface numbers are the labels for ports on the face plate of a switch. As Netvisor ONE supports flexing of ports (breaking a high speed port to lower speed ports) the logical port numbers in the software may not match the bezel interface numbers. The bezel interface numbers may deviate from the logical port numbers in order to represent each logical port uniquely. To display the mapping of logical ports to bezel interface numbers on Netvisor ONE platforms, use the command:
CLI (network-admin@switch) > bezel-portmap-show
|
bezel-portmap-show |
Display the mapping of logical ports to bezel interface numbers. |
|
port port-number |
Logical port number. |
|
bezel-intf bezel-intf-string |
Bezel interface number. |
CLI (network-admin@switch) > bezel-portmap-show
switch port bezel-intf
------ ---- ----------
switch 1 1
switch 2 1.2
switch 3 1.3
switch 4 1.4
switch 5 2
switch 6 3
switch 7 3.2
switch 8 3.3
switch 9 3.4
switch 10 4
switch 11 4.2
switch 12 4.3
switch 13 4.4
As seen from the above output, the bezel interface numbers 1, 1.2, 1.3, and 1.4 represent a physical port's receptacle connected to a breakout cable with four transceivers. Such transceivers are mapped to logical ports 1, 2, 3 and 4 respectively. For example, it can be a 40 GbE QSFP+ receptacle that is divided into four 10 GbE SFP+ ports or a 100 GbE QSFP28 receptacle that is divided into four 25 GbE SFP28 ports. Also, you can infer from the output that bezel interface 2 is not connected to a breakout cable as there is only a single corresponding logical interface.
Displaying Physical Port Information
You can display physical port information by using the port-phy-show command.
The command displays port state and mode, speed and auto-negotiation settings, Ethernet mode, default VLAN, maximum frame size, and status information.
