By default, the user cannot remotely log in and manage the switch through an L3 VLAN interface or a loopback interface. You need to enable the in-band management function by using the following commands to perform the SSH, TELNET, SNMP and HTTP services through any one of the L3 VLAN interfaces or the loopback interface in the default VRF:
set system inband vlan-interface <vlan-interface>
set system inband loopback <ip-address>
- Set the L3 VLAN interface VLAN400 in the default VRF as the in-band management port.
- Set the loopback interface IP in the default VRF as the in-band management IP.
In-band management provides a method of access to the switch even if the Ethernet0/1 interface is down.
