Description
Use this command to change the settings of an existing SNMP server. You must specify either the current name of the server or the ID returned at creation time. Use the lssnmpserver command to obtain this ID.
To switch from an SNMPv3 server to an SNMPv2 server, you must specify the -community parameter.
For syslog servers, SNMP servers, and email users with type set to
local, the valid combinations of notification types are:
- error, warning, and info
- error and warning
Note: The port defaults to 10162 instead of 162 if tls is set to on and
no other port is specified.
