Switch 8800 Family series switches can be managed remotely through network 
management software (NMS). Administrators can use SNMP to access an Switch 
8800 Family series switch. Proper ACL configuration can prevent unauthorized 
network management users from logging onto the switch.

You have correctly configured log into the switch using SNMP.
