I'm considering using SNMP v3 for management of multiple devices. I'd like to standardise the configuration string used, as long as the encrypted password. As the encrypted password is computed from the engineID, this would mean a single engineID for all devices. Are there any problems in doing this? We are not currently using SNMP v3, so I'm not worried about breaking existing user accounts.
The SNMP Engine ID is automatically generated on each router and they do not need to match. You set the encryption passwords, the Engine ID does not.
Hope that helps.
