For security hardening change the default SNMP v2c communities of public (read only) and private (read write).
Under global configuration mode:
no snmp-server community public
no snmp-server community private
snmp-server community NewRead group readgrp index first secname readview
snmp-server community NewWrite group v1v2grp index second secname initialview
Type show snmp-server community and see the list of indexes in the Community Table (first, second etc…) as there may be others as well created for VRFs.
Generate a license .XML file on the support portal using a valid voucher ID and match against the switch base MAC address and serial number (type show sys-info command).
Copy .XML file to /intflash and then type load-license command from configuration mode. This will install the premier license. Type show license command to confirm license is in place and type save config.
On the portal the license files can be seen against the customer and switch type under assets. In the event of a replacement switch the license file can be edited with a new base MAC and serial number.
