immediately terminated as the management interface loses its IP address.

In-Band Management

In-band management is a management path passing through the data ports. In-band management
can be created over one of the VLANs in the systems.
The in-band management feature does not require any license. However, it works only for system
profiles VPI and Ethernet. It cannot be enabled with IP Routing or IP Proxy-ARP.

Create a VLAN. Run:
Step 1.
switch (config) # vlan 10
