18. Congure in-band management or out-of-band management:
• With in-band management, you can congure a network port interface as the management
interface and connect it to the management device. In this scenario, you can do either of the
following:
• Use the automacally created VLAN named default for management of all data interfaces as
members of the default VLAN. Specify the management IP address and the default gateway.
• Create a new management VLAN. Specify the VLAN name, VLAN ID, management IP
address, and default gateway. Select the ports that must be part of this VLAN.
• With out-of-band management, you use a dedicated management channel (MGMT, C0, or C1
port) to connect to the management device. Specify the IP address and gateway of the
management interface. Use this IP address to connect to the switch.
19. (Oponal) Specify the SNMP read community, locaon, and contact to congure SNMP parameters.
20. (Oponal) Specify the system date and me. Select the me zone from the list. The congured
parameters are displayed.
21. Enter yes to commit the conguraon. The conguraon is commied as the acve conguraon
for the switch.
22. (Oponal) Congure addional properes by adding the necessary conguraon statements.
23. Commit the conguraon to acvate it on the switch.
