Version Description
9.9(0.0) Introduced on the FN IOM.
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information The following example congures 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 dened by
the community MIB.
If a community string is congured 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 congure 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.
