sledLoopbackPktHdr
Module: SLED-MIB
OID (symbolic): SLED-MIB::sledLoopbackPktHdr
OID (numeric): 1.3.6.1.4.1.4491.2.1.13.1.2.3
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-write
Description: A 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'.
What is sledLoopbackPktHdr?
This object holds the properly formatted Ethernet(DIX)+IP+UDP header used for SLED loopback processing, with the IP header checksum, IP total length, UDP length, and UDP checksum fields recomputed automatically; it cannot be set while sledLoopbackEnable is true. Admins configure this header template before starting a loopback test so returned packets carry correctly addressed IP/UDP framing. For example, an admin populates sledLoopbackPktHdr with a specific source/destination IP pair before enabling loopback so the return traffic routes correctly to the monitoring station.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4491.2.1.13.1.2.3 snmpwalk -v2c -c public <target> SLED-MIB::sledLoopbackPktHdr
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.4491.2.1.13.1.2.3.1 snmpget -v2c -c public <target> SLED-MIB::sledLoopbackPktHdr.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.4491.2.1.13.1.2.3.1 s <value>
Start monitoring eDOCSIS-embedded cable device, e.g. cable modem/eMTA with embedded application (loopback diagnostic test config) with a free 30-day trial of IPNetwork Monitor. Create custom SNMP monitor using the SLED-MIB::sledLoopbackPktHdr OID value, configure state conditions and alerts, and monitor any eDOCSIS-embedded cable device, e.g. cable modem/eMTA with embedded application (loopback diagnostic test config) from a single console.
