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:
1. In the snmpAgentMIB , select the interface where the Mediatrix 4104 can be accessed via SNMP in
the snmpAgentAccess variable.
You have the following choices:
SNMP Service Agent
You can define whether the unit can be configured via SNMP or exclusively via its web interface.
1. 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.
Current MIB Version
You can find out the version of the MIB currently in the Mediatrix 4104.
1. In the sysMgmtMIB , locate the sysMibVersion variable.
This variable displays the current version of the MIB.
