Usage Information

The following example configures a community named public that is mapped to the security named guestuser with Read Only ( ro) permissions.

The security-name parameter maps the community string to an SNMPv3 user/security name as defined by the community MIB.

If a community string is configured without a security-name (for example, snmp-server community public ro), the community is mapped to a default security-name/group:

v1v2creadu / v1v2creadg — maps to a community with ro (read-only) permissions.
v1v2cwriteu/ v1v2cwriteg — maps to a community with rw (read-write) permissions.

The community-name parameter indexes this command.

If you do not configure the snmp-server community command, you cannot query SNMP data. Only Standard IPv4 ACL and IPv6 ACL is supported in the optional access-list-name.

The command options ipv6, security-name, and access-list-name are recursive. In other words, each option can, in turn, accept any of the three options as a sub-option, and each of those sub-options can accept any of the three sub-options as a sub-option, and so forth. The second Example shows the creation of a standard IPv4 ACL called snmp-ro-acl and then assigning it to the SNMP community guest.

NOTE: For IPv6 ACLs, only IPv6 and UDP types are valid for SNMP; TCP and ICMP rules are not valid for SNMP. In IPv6 ACLs, port rules are not valid for SNMP.

Example

Dell#config
                                             Dell(conf)# snmp-server community public ro
                                             Dell(conf)# snmp-server community guest ro security-name guestuser
                                             Dell(conf)#

Example

Dell(conf)# ip access-list standard snmp-ro-acl
                                             Dell(config-std-nacl)#seq 5 permit host 10.10.10.224
                                             Dell(config-std-nacl)#seq 10 deny any count
                                             !
                                             
                                             Dell(conf)#snmp-server community guest ro snmp-ro-acl
                                             Dell(conf)#
