1   About Standard SNMP MIBs

Simple Network Management Protocol (SNMP) consists of three key components:

SNMP uses Management Information Base (MIB) to collect system data. A MIB is a collection of information organized hierarchically. There are two types of MIBs objects:

Object Identifiers (OIDs) uniquely identify managed objects in a MIB hierarchy. For Ericsson MIB hierarchy information, see Enterprise MIBs.

Note:  
SNMP examples that are provided in this document use the open source tool, Net-SNMP. Depending on the product you use to monitor your network, the examples may appear different from your system.

1.1   Supported Standard SNMP MIBs

The following list identifies the standard IETF MIBs supported by the SmartEdge router :

Note:  
This document only provides specific details on supported objects for the IEEE8021-CFM-MIB, IF-MIB, IP-MIB, and ENTITY-MIB.

Note:  
If you have a support contract, you can download the Enterprise MIBs after you log on at https://ebusiness.ericsson.net.

2   Understanding Notifications

To enable the linkUp and linkDown notifications on the IF-MIB encapsulation layers, issue the traps CLI command in SNMP server configuration mode. For more information on the notifications in IF-MIB, see SNMP MIB Notifications.

3   Using IEEE8021-CFM-MIB

The IEEE8021-CFM-MIB is the Connectivity Fault Management (CFM) module for managing IEEE 802.1ag.

To access objects in IEEE8021-CFM-MIB, the SNMP configuration might need to be modified. This MIB is located within the IEEE 802 branch of the OID tree. All other supported MIBs are a part of the Internet branch of the OID tree.

The following IEEE8021-CFM-MIB objects are supported:

To add the IEEE8021-CFM-MIB to the SNMP view that was defined when configuring SNMP, do the following:

Set the SNMP all view to include all MIBs from the Internet branch.
[local] Redback(config)#snmp view all internet include
Set the SNMP all view to include all MIBs from the ieee8021CfmMib branch.
[local] Redback(config)#snmp view all ieee8021CfmMib include

To find information about the configured maintenance association endpoints (MEPs), do the following:

  1. Configure a new view name (Everything) using the CLI.
[local] Redback(config)# snmp view Everything internet included
[local] Redback(config)# snmp view Everything ieee8021CfmMib included 
[local] Redback(config)# snmp community public view Everything read-write
[local] Redback(config)# commit 
[local] Redback(config)# end 
[local] Redback#
  1. In your SNMP management tool, perform an SNMP snmpwalk for the Everything view.

4   Using IF-MIB on Ericsson Systems

IF-MIB is a standard MIB as referenced in RFC 2863, The Interfaces Group MIB. Use IF-MIB to display port, IP interface, and selected circuit information.

Use the snmp server CLI command (in global configuration mode) with the enhance ifmib keyword to enable IF-MIB enhancements, such as selected circuit support.

4.1   Related CLI Commands

Use the following CLI commands to configure IF-MIB on the SmartEdge router . More information on individual commands is available in Command List.

4.3.2.2   Understanding ifName and ifDescr

The ifDescr object contains the same value as ifName when IF-MIB is enabled when configuring SNMP.

The ifName object is the interface type in textual format, that is, the port, channel, or subchannel name. If several entries represent a single interface, they should have the same ifName value or a common ifName prefix and unique suffix.

To create an 802.1Q PVC in an 802.1Q tunnel with the CLI, do the following:

[local]Redback(config)#port ethernet 2/3
[local]Redback(config-port)#no shutdown
[local]Redback(config-port)#encapsulation dot1q
[local]Redback(config-port)#dot1q pvc 1 encapsulation lqtunnel
[local]Redback(config-port)#dot1q pvc 1 encapsulation 1qtunnel
[local]Redback(config-dot1q-pvc)#dot1q pvc 1:100
[local]Redback(config-dot1q-pvc)#dot1q pvc 1:200
[local]Redback(config-dot1q-pvc)#dot1q pvc 1:300
[local]Redback(config)#port ethernet 2/4
[local]Redback(config-port)#no shutdown
[local]Redback(config-port)#encapsulation dot1q
[local]Redback(config-port)#dot1q pvc 2
[local]Redback(config-port)#dot1q pvc 3 encapsulation 1qtunnel
[local]Redback(config-dot1q-pvc)#dot1q pvc 3:100
[local]Redback(config-dot1q-pvc)#dot1q pvc 3:200

When using snmpwalk, the system adds the prefix port to each ifName object and a suffix of numbers that provides more information about the location of the port.

To view the SNMP configuration, do the following:

test 91: snmpwalk -v2c test.lab public ifName
ifName.1 = port ethernet 1/1
ifName.2 = port ethernet 2/3
ifName.3 = port ethernet 2/4
ifName.16777222 = port ethernet 2/3 dot1q pvc 1 1/2/6
ifName.16777223 = port ethernet 2/3 dot1q pvc 1:100 1/2/7
ifName.16777224 = port ethernet 2/3 dot1q pvc 1:200 1/2/8
ifName.16777225 = port ethernet 2/3 dot1q pvc 1:300 1/2/9
ifName.16777228 = port ethernet 2/4 dot1q pvc 2 1/2/12
ifName.16777229 = port ethernet 2/4 dot1q pvc 3 1/2/13 
ifName.16777230 = port ethernet 2/4 dot1q pvc 3:100 1/2/14
ifName.16777231 = port ethernet 2/4 dot1q pvc 3:200 1/2/15
ifName.67108864 = mgmt

4.3.2.3   Collecting Port Statistics with ifTable

The ifTable table provides collection of port statistics that the management system needs. The ifTable object is indexed by the ifIndex object, the ifIndex values are assigned for each interface.

To collect ifTable port statistics, do the following:

The relevant counters are the specific instances associated with this interface of any Counter32 or Counter64 object contained in the ifTable or ifXTable. If no such discontinuities have occurred since the last re- initialization of the local management subsystem, then this object contains a 0 (zero) value.

4.3.4   ifStackTable

Implementation of the Interface Stack group (ifStackTable) is optional but recommended for all systems. This table contains information on the relationships between the multiple network interface sublayers. In particular, it contains information on which sublayers overlap other sublayers and where each sublayer corresponds to a conceptual row in ifTable. For example, when the sublayer with the ifIndex value x is stacked on the sublayer with ifIndex value y, this table contains:

ifStackStatus.x.y=active

For each ifIndex value, I, that identifies an active interface, at least two instantiated rows in this table are always associated with I. For one of these rows, I is the value of the ifStackHigherLayer object; for the other row, I is the value of the ifStackLowerLayer object. (If I is not involved in multiplexing, then these rows are the only two rows associated with I.)

For example, two rows exist even for an interface that has no other rows stacked above or below it:

ifStackStatus.0.x=active
ifStackStatus.x.0=active

Index: ifStackHigherLayer, ifStackLowerLayer

Table 8 describes the objects in ifStackTable. All objects are read-only.

A change of the interface stack is a creation, deletion, or change in value of any instance of the ifStackStatus object. If the interface stack is unchanged since the last reinitialization of the local network management subsystem, then the value of this object is 0 (zero).

4.3.5   ifRcvAddressTable

The Generic Receive Address group (ifRcvAddressTable) is mandatory for all interface types that receive packets and frames addressed to more than one address.

This table contains an entry for each address (broadcast, multicast, or unicast) for which the system receives packets and frames on an interface, except the following interface types:

A system can use any unicast address as a source address that corresponds to an entry in this table.

This group is mandatory for network interfaces that maintain counters (that is, those for which one of the ifFixedLengthGroup, ifHCFixedLengthGroup, ifPacketGroup, ifHCPacketGroup, or ifVHCPacketGroup counters is mandatory).

This group contains only one object: ifCounterDiscontinuityTime.

Object Group Identifier: ifGroups 13

4.5   ifIndex Persistency

The ifIndex is a unique value, greater than zero, for each interface. SmartEdge supports an ifIndex value that persists across reboots and switchovers for a subset of interfaces, specifically IP interfaces, ports, and static circuits. To do this, ifIndex persistence maps the ifName and ifIndex object values and retains this mapping across reboots and switchovers.

ifIndex persistence occurs when an ifIndex value assigned to a specific circuit, port (ports can have a range of ifIndex values) or IP interface is reapplied after SNMP restarts. In SmartEdge , the persistent ifIndex assignment uses the range 0 to 0x08ffffff, as shown in Table 18.

ifIndex persistence for ports, IP interfaces, and static circuits must be configured when they are created during the SmartEdge configuration. ifIndex persistent assignments are based on the startup CLI configuration file or the binary database if the configuration file has not changed between reboots.

IF-MIB persistence of ports are lost when the port configuration in the startup CLI configuration file changes.

IF-MIB persistence of static circuits and IP interfaces are lost in the following situations:

Note:  
If the save config CLI command is issued, the newly assigned ifIndex values will be persistent at reboot. If the command is not issued, the ifIndex values that were used in the last saved configuration will be persistent at reboot.

Table 18 lists the range of values for the ifIndex and Interface Groups for which the values are reserved.

5   Using IP-MIB on Ericsson Systems

This MIB is composed of a small number of discrete objects and a series of tables meant to form the base for managing IPv4 and IPv6 entities. While some of the objects are meant to be included in all entities, some of the objects are only conditionally mandatory. The unconditionally mandatory objects are mostly counters for IP and ICMP statistics.

5.1   IP-MIB Objects

The conditionally mandatory objects for IP-MIB fall into one of several groups:

5.1.1   ipSystemStatsTable

The table containing system wide, IP version specific traffic statistics. This table and the ipIfStatsTable contain similar objects whose difference is in their granularity. Where this table contains system wide traffic statistics, the ipIfStatsTable contains the same statistics but counted on a per-interface basis.

Index: ipSystemStatsIPVersion

Table 19 describes the objects in ipSystemStatsTable. All objects in the table are read-only, unless otherwise noted.

5.1.3   Finding Information for Each IP Address

To find the context and the interface, circuit name, or identifier for a given IP address, use the ipAddrTable object in IP-MIB to retrieve the ifIndex object for a given IP address.

To obtain a list of the contexts that reside on the SmartEdge router, do the following:

  1. Perform an snmpbulkwalk of vacmContextTable.
sh$ snmpbulkwalk -v public -v2c -m SNMPv3-VACM-MIB SE-test vacmContextTable
SNMP-VIEW-BASED-ACM-MIB::vacmContextName."" = STRING:
SNMP-VIEW-BASED-ACM-MIB::vacmContextName."BASIC" = STRING: BASIC

6   Using ENTITY-MIB on Ericsson Systems

ENTITY-MIB contains a mapping table that is used to identify physical components that have identifiers from other standard MIBs. For example, this table can be used along with the physical mapping table to identify the physical location of each repeater port in the rptrPortTable, or each interface in the ifTable.

6.1   ENTITY-MIB Objects

The SNMP management system ENTITY-MIB collects information about the chassis type, card type, and number of ports. EntPhysicalTable in ENTITY-MIB is indexed by the PhysicalIndex, which is an arbitrary unique value to identify each physical entity in the chassis.

The entAliasMappingTable table in ENTITY-MIB version 3 provides a mechanism to map ifIndex to entPhysicalIndex. Performing an snmpwalk on entAliasMappingTable and ifTable displays mapping between ifIndex and physical ports. The mapping should happen regardless of line card or platform.

6.1.1   Global Objects

Global objects are a collection of objects used to represent general entity information, for which a single agent provides management information.

Table 21 describes the global objects in ENTITY-MIB. All objects in the table are read-only.

entPhysicalEntry 2

SnmpAdminString


OctetString

0..255

A textual description of the physical entity. This object should contain a string that identifies the manufacturer's name for the physical entity, and should be set to a distinct value for each version or model of the physical entity

entPhysicalVendorType


entPhysicalEntry 3

AutonomousType

ObjectID

An indication of the vendor-specific hardware type of the physical entity. Note that this is different from the definition of MIB-II's sysObjectID. An agent should set this object to an enterprise-specific registration identifier value indicating the specific equipment type in detail. The associated instance of entPhysicalClass is used to indicate the general type of hardware device. If no vendor-specific registration identifier exists for this physical entity, or the value is unknown by this agent, then the value { 0 0 } is returned.

entPhysicalContainedIn


entPhysicalEntry 4

PhysicalIndexOrZero


Integer32

0..2147483647

The value of entPhysicalIndex for the physical entity which 'contains' this physical entity. A value of zero indicates this physical entity is not contained in any other physical entity. Note that the set of 'containment' relationships define a strict hierarchy; that is, recursion is not allowed. In the event that a physical entity is contained by more than one physical entity (e.g., double-wide modules), this object should identify the containing entity with the lowest value of entPhysicalIndex.

5—container


6—powerSupply


7—fan


8—sensor


9—module


10—port


11—stack


12—cpu

An indication of the general hardware type of the physical entity. An agent should set this object to the standard enumeration value that most accurately indicates the general class of the physical entity, or the primary class if there is more than one entity. If no appropriate standard registration identifier exists for this physical entity, then the value 'other(1)' is returned. If the value is unknown by this agent, then the value 'unknown(2)' is returned.

entPhysicalParentRelPos


entPhysicalEntry 6

Integer32

-1..2147483647

An indication of the relative position of this 'child' component among all its 'sibling' components. Sibling components are defined as entPhysicalEntries that share the same instance values of each of the entPhysicalContainedIn and entPhysicalClass objects.

entPhysicalName


entPhysicalEntry 7

SnmpAdminString


OctetString

0..255

The textual name of the physical entity. The value of this object should be the name of the component as assigned by the local device and should be suitable for use in commands entered at the device's `console'.

6.1.3   entAliasMappingTable

This table contains zero or more rows, representing mappings of logical entity and physical component to external MIB identifiers. Each physical port in the system may be associated with a mapping to an external identifier, which itself is associated with a particular logical entity's naming scope. A 'wildcard' mechanism is provided to indicate that an identifier is associated with more than one logical entity.
