CLI Guide

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)#
