3.9 SNMP communication failures
3.9.1 MIBs cannot be obtained from the SNMP manager
Make sure the configuration has been registered correctly.
When using SNMPv1 or SNMPv2c
Execute the
show running-config operation command, and check whether the
community name and access list have been registered correctly. If IP addresses for
the SNMP manager to which access is permitted are not restricted, an access list
need not be set.
If the community name and access list have not been registered, execute the
snmp-server community configuration command to set information about the
SNMP manager.
# show running-config
:
:
ip access-list standard SNMPMNG
permit host 128.1.1.2
snmp-server community "NETWORK" ro SNMPMNG
#
3.9.2 Traps cannot be received by the SNMP manager
Make sure the configuration has been registered correctly.
When using SNMPv1 or SNMPv2c
Execute the
show running-config operation command, and check whether the
information about the SNMP manager and traps has been registered in the
configuration for the Switch.
If the information has not been registered, execute the
snmp-server host
configuration command to set the information about the SNMP manager and traps.
# show running-config
