SNMP Access Limitation

The SNMP access to the Mediatrix 4104 can be limited to only one of its interface or all interfaces. 

To limit the access to the SNMP interface:

snmpAgentMIB

, select the interface where the Mediatrix 4104 can be accessed via SNMP in 

the

In the 

snmpAgentMIB

, define the SNMP service agent status in the 

snmpAgentEnable

 variable.

The SNMP service agent controls whether the Mediatrix 4104 may be accessed via SNMP or not. 

•

enable: SNMP connections are allowed.

•

disable: SNMP connections are forbidden.

If you are exclusively using the web page to configure the Mediatrix 4104, you could disable the 

SNMP service agent and forbid any SNMP connection to the unit. 

If the SNMP agent is disabled and the unit enters into recovery mode, SNMP connections are 

allowed during that time. Once the unit returns to its normal state, the SNMP service agent will revert 

to the configuration you have set.

In the 

sysMgmtMIB

variable.
