Description: ENTERASYS-MIRROR-CONFIG-MIB module

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is ENTERASYS-MIRROR-CONFIG-MIB?

This MIB module belongs to Enterasys Networks' enterprise-specific SNMP tree and defines objects for configuring network traffic mirroring (port mirroring/SPAN) on Enterasys switches and routers. It exposes configuration data such as the maximum number of local and remote mirror sessions supported, mirror destination control table entries, and mirror destination port assignments. While primarily a configuration MIB, it also supports monitoring of mirroring session status and resource limits, letting an administrator confirm that a device's mirroring capacity (e.g., etsysMirrorSystemMaxLocalMirrors) is not exhausted and that mirror sessions are correctly provisioned and active via row status. It is a self-contained vendor-specific MIB, not built directly atop another standard MIB, though it follows general SNMP conventions for identifying source and destination ports. It is typically deployed in enterprise or campus network environments using Enterasys (later Extreme Networks) switches for troubleshooting and traffic analysis via mirrored/SPAN ports. Engineers can download the ENTERASYS-MIRROR-CONFIG-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ENTERASYS-MIRROR-CONFIG-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

Enterasys Networks switches
Enterasys/Extreme Networks routers

Monitoring Examples

An administrator can poll etsysMirrorDestinationControlTable to see configured mirror sessions, each identified by etsysMirrorDestinationControlIndex, along with etsysMirrorDestinationControlRowStatus to confirm a session is active. Checking etsysMirrorSystemMaxLocalMirrors and etsysMirrorSystemMaxRemoteMirrors against the number of provisioned entries reveals whether the switch is near its mirroring capacity, which would explain failures to add new SPAN sessions. The etsysMirrorDestinationPortTable identifies which physical ports are currently receiving mirrored traffic for a diagnostic capture.

What Can Be Monitored

mirror session configuration status
local/remote mirror capacity limits
mirror destination port assignments
mirror destination control group count
row status of mirror sessions

OIDs

OID symbolic	OID numeric	Type	Access	Description
etsysMirrorConfigMIB	1.3.6.1.4.1.5624.1.2.72			This MIB module defines a portion of the SNMP MIB under the Enterasys Networks enterprise OID pertaining to Network Mirroring configuration on a device.
etsysMirrorSystem	1.3.6.1.4.1.5624.1.2.72.1
U32 etsysMirrorSystemMaxLocalMirrors	1.3.6.1.4.1.5624.1.2.72.1.1	Unsigned32	read-only	This value represents the maximum number of local mirrors that the device supports.
U32 etsysMirrorSystemMaxRemoteMirrors	1.3.6.1.4.1.5624.1.2.72.1.2	Unsigned32	read-only	This value represents the maximum number of remote mirrors that the device supports.
U32 etsysMirrorSystemMaxLocalMirrorDestinationPorts	1.3.6.1.4.1.5624.1.2.72.1.3	Unsigned32	read-only	This value represents the maximum number of destination ports supported for a local mirror.
U32 etsysMirrorSystemMaxMirrorDestinationControlGroups	1.3.6.1.4.1.5624.1.2.72.1.4	Unsigned32	read-only	This value represents the maximum number of rows in the etsysMirrorDestinationControlTable.
etsysMirrorConfig	1.3.6.1.4.1.5624.1.2.72.2
U32 etsysMirrorDestinationNextAvailableIndex	1.3.6.1.4.1.5624.1.2.72.2.1	Unsigned32	read-only	This object indicates the numerically lowest available index within this entity, which may be used for the value of etsysMirrorDestinationControlIndex in the creation of a new entry in the etsysMirrorDestinationControlTable. An index is considered available if the index value falls within the range of 1 to (newLeaf with max dest groups) and is not being used to index an existing entry in the etsysMirrorDestinationControlTable contained within this entity. A value of zero indicates that all of the entries in the etsysMirrorDestinationControlTable are currently in use. This value SHOULD only be considered a guideline for management creation of etsysMirrorDestinationControlTable entries, there is no requirement on management to create entries based upon this index value.
etsysMirrorDestinationControlTable	1.3.6.1.4.1.5624.1.2.72.2.2		not-accessible	Controls the setup of mirror destination ports on the managed device.
etsysMirrorDestinationControlEntry	1.3.6.1.4.1.5624.1.2.72.2.2.1		not-accessible	A conceptual row in the etsysMirrorDestinationControlTable.
U32 etsysMirrorDestinationControlIndex	1.3.6.1.4.1.5624.1.2.72.2.2.1.1	Unsigned32	not-accessible	A unique arbitrary index for this etsysMirrorDestinationControlEntry.
STR etsysMirrorDestinationControlOwner	1.3.6.1.4.1.5624.1.2.72.2.2.1.2	SnmpAdminString	read-create	Administratively assigned name of the owner of this entry. It usually defines the entity that created this entry and is therefore using the resources assigned to it, though there is no enforcement mechanism, nor assurance that rows created are ever used.

ROW etsysMirrorDestinationPortRowStatus	1.3.6.1.4.1.5624.1.2.72.2.3.1.2	RowStatus	read-create	This object manages the creation and deletion of this entry. active(1) -- Indicates that this entry is available for use by the managed device. notInService(2) -- Indicates that this entry exists in the agent but is not available for use by the managed device. notReady(3) -- Entry is missing information in order to be available for use by the managed device. A transition to this state will happen when the etsysMirrorDestinationIfIndex object for this entry is 0 (zero). createAndGo(4) -- A new entry will be created in this table and the new entry will transition to the active state. createAndWait(5) -- A new entry will be created in this table and the new entry will transition to the notInService state. destroy(6) -- Deletes this row.
