MP-1xx SIP User’s Manual 11. SNMP-Based Management SNMP-Based Management Simple Network Management Protocol (SNMP) is a standard-based network control protocol used to manage elements in a network. The SNMP Manager (usually implemented by a Network Manager (NM) or an Element Manager (EM)) connects to an SNMP Agent (embedded on a remote Network Element (NE)) to perform network element Operation, Administration and Maintenance (OAM).
MP-1xx SIP • Trap Message - The SNMP standard furnishes a mechanism by which devices can ‘reach out’ to a Network Manager on their own (via a ‘trap’ message) to notify or alert the manager of a problem with the device. This typically requires each device on the network to be configured to issue SNMP traps to one or more network devices that are awaiting these traps.
MP-1xx SIP User’s Manual 11. SNMP-Based Management 11.2 Carrier Grade Alarm System The basic alarm system has been extended to a carrier-grade alarm system.

A carrier-grade alarm system is characterized by the following: •...
ALARM-MIB - This is an IETF proposed MIB also supported as part of our implementation of carrier grade alarms. This MIB is still not standard and is therefore under the audioCodes.acExperimental branch. • SNMP-TARGET-MIB - This MIB is partially supported (RFC 2273). It allows for the configuration of trap destinations and trusted managers only.

MP-1xx SIP User’s Manual B. The BootP/TFTP Configuration Utility BootP/TFTP Application User Interface Figure B-1 shows the main application screen for the BootP/TFTP utility. Figure B-1: Main Screen Log Window Function Buttons on the Main Screen Pause: Click this button to pause the BootP Tool so that no replies are sent to BootP requests.
MP-1xx SIP When a gateway resets, it first sends a BootRequest. Therefore, Reset can be used to force a BootP session with a gateway without needing to power cycle the gateway. As with any BootP session, the computer running the BootP Tool must be located on the same subnet as the controlled VoIP gateway.
MP-1xx SIP User’s Manual B. The BootP/TFTP Configuration Utility B.10 Setting the Preferences The Preferences window, Figure B-3, is used to configure the BootP Tool parameters. Figure B-3: Preferences Screen B.10.1 BootP Preferences ARP is a common acronym for Address Resolution Protocol, and is the method used by all Internet devices to determine the link layer address, such as the Ethernet MAC address, in order to route Datagrams to devices that are on the same subnet.
MP-1xx SIP • ARP Type: The type of entry made into the ARP cache on the computer, once ARP Manipulation is enabled, can be either Dynamic or Static. Dynamic entries expire after a period of time, keeping the cache clean so that stale entries do not consume computer resources.
MP-1xx SIP User’s Manual B.

MP-1xx SIP To add a client to the list using a template, take these 5 steps: Click on the Add New Client Icon; a client with blank parameters is displayed. In the field Template, located on the right side of the Client Configuration Window, click on the down arrow to the right of the entry field and select the template that you want to use.
MP-1xx SIP User’s Manual B. The BootP/TFTP Configuration Utility B.11.5 Setting Client Parameters Client parameters are listed on the right side of the Client Configuration Window. • Client MAC: The Client MAC is used by BootP to identify the VoIP gateway. The MAC address for the VoIP gateway is printed on a label located on the VoIP gateway hardware.
MP-1xx SIP B.11.6 Using Command Line Switches You can add command line switches in the field Boot File. To use a Command Line Switch, take these 4 steps: In the field Boot File, leave the file name defined in the field as it is (e.g., ramxxx.cmp). Place your cursor after cmp.
