Our customer is trying to find a way to be able to access the switch via IP without plugging into the management port.

Can't access the switch via IP without plugging into the management port.

In-band management interface: In in-band management, you configure a network interface as a management interface and connect it to the management device.

configure

Define VLAN: Define the VLAN by assigning it a VLAN ID and optionally, a name.

set vlans management-vlan vlan-id <vlan-id>

Assign Interface to VLAN: Assign an interface to the management VLAN.

set interfaces <interface-name> unit 0 family ethernet-switching vlan members management-vlan

Replace <interface-name> with the name of the interface you want to assign to the management VLAN.

Create IRB Interface: Create an IRB interface for the management VLAN.

set interfaces irb unit 0 family inet address <management-ip-address>/<subnet-mask>

Replace <management-ip-address> and <subnet-mask> with the IP address and subnet mask you want to assign to the IRB interface.

Configure Gateway: If necessary, configure the default gateway for the management interface.

set routing-options static route 0.0.0.0/0 next-hop <gateway-ip-address>

Replace <gateway-ip-address> with the IP address of your default gateway.
