cktIWF1490to1483LastBadHeader
Module: CASCADE-MIB
OID (symbolic): CASCADE-MIB::cktIWF1490to1483LastBadHeader
OID (numeric): 1.3.6.1.4.1.277.1.6.1.1.221
Node type: OBJECT-TYPE
Type: DisplayString
Access: read-only
Description: Ascii string of the first 8 bytes of the header from the last frame discarded because the 1490 to 1483 header translation failed. The string displays the hexidecimal values for the data bytes
What is cktIWF1490to1483LastBadHeader?
This read-only DisplayString captures the first 8 bytes, rendered as hexadecimal values, of the header from the last frame that was discarded because RFC 1490-to-1483 header translation failed on this interworked circuit. This is essentially a diagnostic snapshot the switch preserves specifically to help troubleshoot the error counted by cktIWF1490to1483Error, letting an engineer see exactly what bytes the far-end FR device sent that the ATM interworking function couldn't recognize. An engineer debugging a persistent translation failure would read cktIWF1490to1483LastBadHeader and compare the hex bytes against the expected RFC 1490 NLPID/SNAP header format to spot exactly which field is malformed.
