SLED-MIB

AI MIB Summary

The SLED-MIB module enables the configuration and invocation of Software Loopback Application (SLED) functionality within eDOCSIS cable modems and CMTS systems to facilitate remote loopback testing for physical layer diagnostics. It manages specific operational states and control parameters required to initiate, monitor, and terminate software-based loopback sessions on DOCSIS interfaces.

This MIB module provides the management objects necessary to configure and invoke the Software Loopback Application for eDOCSIS (SLED) functionality. Copyright 1999-2007 Cable Television Laboratories, Inc. All rights reserved.

OBJECT IDENTIFIER
.1.3.6.1.4.1.4491.2.1.13.1.1
sledGlobalEnableThis object allows the SLED functionality to be enabled/disabled. This object may only be updated prior to device registration. If the device has completed registration, any attempt to update the value of this object returns 'notWritable'. Prior to registration, if the value of this object is set to 'true', the SLED functionality is enabled and access to this MIB is allowed. Prior to registration, if the value of this object is set to 'false', the SLED functionality is disabled and any attempt to update other objects in this MIB returns 'noAccess'.rw

sledLoopback
OBJECT IDENTIFIER
.1.3.6.1.4.1.4491.2.1.13.1.2
sledLoopbackInterfaceThe index of the logical CPE interface (LCI) that the SLED loopback function is attached to. If the index does not correspond to a LCI supported by this device, 'wrongValue' is returned. Any attempt to set this object while sledLoopbackEnable is set to 'true' returns'notWritable'.rw
InterfaceIndex (IF-MIB)
.1.3.6.1.4.1.4491.2.1.13.1.2.1
sledLoopbackEnableSetting this object to 'true' enables the loopback function. Setting this object to 'false' disables the loopback function. When enabled, the eCM removes the Ethernet FCS/CRC32 from the original packets. All Ethernet packets received by the SLED from the LCI are then processed as follows: 1. If the received Ethernet packet is greater than 1472 octets, the Ethernet packet is split into two fragments, the first consisting of the first 1472 octets of the Ethernet packet and the second containing the remaining octets, resulting in two payloads that are processed as described below. If the received Ethernet packet is less than or equal to 1472 octets, the entire packet will be processed as a single payload. 2. For each payload generated in step 1, the payload is appended to the contents of sledLoopbackPktHdr. 3. The mutable fields within sledLoopbackPktHdr MUST be recomputed. The mutable fields are IP Header Checksum, IP Total Length, UDP Checksum, and UDP Length. 4. If the Ethernet packet was fragmented in step 1, the appropriate IP header fields (Flags and Fragment Offset) are updated to indicate IP fragmentation These IP fragmentation header values will differ depending on if this is the first or second fragment being processed. 5. The Ethernet FCS is computed and appended. 6. The resulting Ethernet packet is transmitted to the LCI.rw
TruthValue (SNMPv2-TC)
.1.3.6.1.4.1.4491.2.1.13.1.2.2
sledLoopbackPktHdrA properly formatted Ethernet(DIX)+IP+UDP headers for use in SLED loopback processing as described in sledLoopbackEnable. The object value contains mutable fields that are recomputed: the IP Header Checksum, IP Total Length, UDP Length, and UDP Checksum. Any attempt to set this object while sledLoopbackEnable is set to 'true' returns 'notWritable'.rw

sledPktGen
OBJECT IDENTIFIER
.1.3.6.1.4.1.4491.2.1.13.1.3
sledPktGenInterfaceThe index of the logical CPE interface (LCI) that the SLED packet generation function is attached to. If the index does not correspond to a LCI supported by the device, 'wrongValue' is returned. Any attempt to set this object while sledPktGenTrigger is set to 'start' returns 'notWritable'.rw
InterfaceIndex (IF-MIB)
.1.3.6.1.4.1.4491.2.1.13.1.3.1
sledPktGenPayloadThe properly formatted Ethernet packet payload to be generated. Any attempt to set this object while sledPktGenTrigger is set to 'start' returns 'notWritable'.rw
OCTET STRING
.1.3.6.1.4.1.4491.2.1.13.1.3.2
sledPktGenRateThe packet rate (in packets per second) that the SLED is to transmit the packet specified in the sledPktGenPayload. Any attempt to set this object while sledPktGenTrigger is set to 'start' returns 'notWritable'.rw
Unsigned32
.1.3.6.1.4.1.4491.2.1.13.1.3.3
sledPktGenNumPktsNumber of packets to be generated at the rate specified by sledPktGenRate. Any attempt to set this object while sledPktGenTrigger has been set to 'start' will return 'notWritable'.rw
Unsigned32
.1.3.6.1.4.1.4491.2.1.13.1.3.4
sledPktGenTriggerThis object controls the packet generation. Setting this object to 'start' causes the packet generation to begin. Reading this object will return 'start' if a packet generation is in progress, otherwise it will return 'stop'. Setting this object to 'stop' while packet generation is in progress aborts the packet generation. Setting this object to 'start' while packet generation is in progress, 'wrongValue' is returned.rw
