What Is ASCEND-ATMP-MIB?

ASCEND-ATMP-MIB is an Ascend Communications (later Lucent) proprietary MIB implementing ATMP (Ascend Tunnel Management Protocol, a mobile-IP-style precursor), which tunnels traffic between a Foreign Agent (FA) and Home Agent (HA) for roaming users. Its objects cover agent mode/type, UDP port, GRE MTU, forced-fragmentation flag, HA idle limit, last-error tracking (sent-to/received-from addresses), trap enable, FA/HA/local tunnel counts and high-water mark, and a tunnel table (ID, HA/FA IP address, tunneled protocol, type, state, mobile-node IP address). As a configuration/status MIB it lets an administrator confirm ATMP tunnel counts and state, and diagnose the last reported ATMP error. It is deployed on Ascend (Lucent) MAX/TNT remote-access equipment using ATMP. Engineers can download the ASCEND-ATMP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ASCEND-ATMP-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Ascend (Lucent) MAX/TNT remote-access equipment (ATMP)

Monitoring Examples

An administrator checks atmpTunnelState and atmpLastErrorGenerated to diagnose a mobile-node ATMP tunnel that failed to establish on an Ascend MAX access server.

What Can Be Monitored

ATMP tunnel state, count, and last error

OIDs

OID symbolic	OID numeric	Type	Access	Description
INT atmpAgentMode	1.3.6.1.4.1.529.24.1	INTEGER	read-only	The type of ATMP Agent.
INT atmpAgentType	1.3.6.1.4.1.529.24.2	INTEGER	read-only	The type of ATMP HA Agent. ha-router means the HA will route the tunneled data to other networks. ha-gateway means the HA delivers tunneled data to other networks without routing anything. A ha-notapp will be returned for FA and if ATMP is disabled.
INT atmpAgentUDPPort	1.3.6.1.4.1.529.24.3	INTEGER	read-only	UDP port number to be used for ATMP.
INT atmpAgentGreMtu	1.3.6.1.4.1.529.24.4	INTEGER	read-only	The maximum IP packet size that can be transmitted to a peer agent without performing fragmentation. The value 0 means this feature is disabled.
INT atmpAgentForceFragmentation	1.3.6.1.4.1.529.24.5	INTEGER	read-only	To force fragmentation of large IP frames before they are sent to the peer agent even if the packet has the DF bit set. NOTE: this behavior is not standard and prevents MTU discovery mechanisms. This works in conjunction with atmpAgentGreMtu.
INT atmpAgentHAIdleLimit	1.3.6.1.4.1.529.24.6	INTEGER	read-only	Time in minutes that the HA will allow a tunnel to have no traffic before tearing it down. The value 0 means this option is disabled.
INT atmpLastErrorGenerated	1.3.6.1.4.1.529.24.7	INTEGER	read-write	This is the last error at the Agent level or Tunnel creation that was generated by the Agent. To clear the field and atmpAgentSentErrorTo do a set with the value no-error(1)
IP atmpAgentSentErrorTo	1.3.6.1.4.1.529.24.8	IpAddress	read-only	The IP Address of the agent that the generated was sent to. Clearing atmpLastErrorGenerated also clears this field.
INT atmpLastErrorRecv	1.3.6.1.4.1.529.24.9	INTEGER	read-write	This is the last error at the Agent level or Tunnel creation that was received from the Peer Agent. To clear the field and atmpAgentRecvErrorFrom do a set with the value no-error(1)
IP atmpAgentRecvErrorFrom	1.3.6.1.4.1.529.24.10	IpAddress	read-only	The IP Address of the agent that the last error received was from. Clearing atmpLastErrorRecv also clears this field.
INT atmpEnableAtmpTraps	1.3.6.1.4.1.529.24.11	INTEGER	read-write	Enable the atmp traps.
INT atmpAgentNumberFATunnels	1.3.6.1.4.1.529.24.12	INTEGER	read-only	The number of FA tunnels.

INT atmpTunnelId	1.3.6.1.4.1.529.24.16.1.2	INTEGER	read-only	The tunnel ID assigned to this tunnel. This number is assigned by the HA. NOTE: this number does not uniquely identify a tunnel.
IP atmpHAIpAddress	1.3.6.1.4.1.529.24.16.1.3	IpAddress	read-only	The IP Address of this tunnel's HA.
