rlCdpCacheVersionExt

Module: CISCOSB-CDP-MIB

OID (symbolic): CISCOSB-CDP-MIB::rlCdpCacheVersionExt

OID (numeric): 1.3.6.1.4.1.9.6.1.101.137.8.1.1

Node type: OBJECT-TYPE

Type: DisplayString

Access: read-only

Description: This field contains the extention of the cdpCacheVersion field in the cdpCache table. In case the neighbour advertised the SW TLV as a string with length larger than 160, this field contains the chacters from place 160 and on. Zero-length strings indicates no Version field (TLV) was reported in the most recent CDP message, or it was smaller than 160 chars

What is rlCdpCacheVersionExt?

This read-only DisplayString holds the overflow portion of a neighbor's CDP software-version string when that string is longer than 160 characters, continuing from character 160 onward; a zero-length value means no version TLV was reported or it was 160 characters or shorter. An admin reads it together with the main cdpCacheVersion field to see the complete software version string of a verbose neighbor. For example, when a neighboring switch advertises an unusually long firmware version string, an admin would need to concatenate this field with the primary version field to see the full text.
