In-band Management Interface
By default, the user cannot remotely log in and manage the switch through an L3 VLAN interface. PICOS provides in-band management in default VRF. In-band management provides a method of access to the switch even if the Ethernet0 interface is down. You can enable in-band management function by setting set system inband enable true or setting set system inband vlan-interface <vlan-interface> to perform the SSH, TELNET, SNMP and HTTP services through any one of the VLAN interfaces in the default VRF.
For example,
Set VLAN interface VLAN400 in the default VRF as the in-band management port.
