Mediatrix 4100

SNMP Configuration

No DHCP value is available, you can define SNMP information with only static values.

The Mediatrix 4100 uses the SNMP protocol for software configuration. Set the following SNMP-related

variable to properly use the protocol.

You can query the SNMP information assigned by the DHCP server in the following variables (in the

ipAddressStatus folder):

 localHostSnmpPort

 msTrapPort

Static DNS

By default, the Mediatrix 4100 receives DNS IP addresses according to the configuration source you have

defined in the localHostSelectConfigSource variable. In general, these addresses are provided by an ISP

(Internet Service Provider) via DHCP.

However, you can set static values for the primary and secondary DNS IP addresses, even when the Mediatrix

4100 is set by DHCP. These static values can thus override DHCP provisioning

The Mediatrix 4100 may receive DNS addresses from two sources:

 from an ISP via DHCP

 from the static local host DNS IP addresses

Table 30

explains how DNS addresses are attributed to the Mediatrix 4100.

Variable Description

localHostStaticSnmpPort Default SNMP agent port, which is the port number to use to reach the local

host via SNMP protocol. Restart the unit to update this parameter.

Default Value: 161

Note: If you change the SNMP agent port, change the port used in the

management server or MIB Browser. Not doing so will prevent you from

contacting the unit.

The Management Server could be the Media5 Unit Manager Network. See

“

Unit Manager Network – Element Management System” on page xvii for more
