- MD5 Password—Users must enter a password that is encrypted using
the MD5 authentication method.
- SHA Password—Users must enter a password that is encrypted by
using the SHA (Secure Hash Algorithm) authentication method.
- MD5 Key—Users are authenticated by using a valid MD5 key.

password, enter the local user password. Local user passwords are
compared to the local database and can contain up to 32 ASCII characters.

key, enter the MD5 or SHA authentication key. If the MD5 key is selected, 16
bytes are required. If the SHA key is selected, 20 bytes are required.

Defining SNMP Communities
Access rights in SNMPv1 and SNMPv2 are managed by defining communities in
the
Communities Page
. The community name is a type of shared password
between the SNMP management station and the device. It is used to authenticate
the SNMP management station.
Communities are only defined in SNMPv1 and v2 because SNMP v3 works with
users instead of communities. The users belong to groups that have access rights
assigned to them.
