tbRxFrameFragments

Module: CXTokenBus-MIB

OID (symbolic): CXTokenBus-MIB::tbRxFrameFragments

OID (numeric): 1.3.6.1.4.1.495.2.1.5.9.2.34

Node type: OBJECT-TYPE

Type: Counter

Access: read-only

Description: This statistic represents the number of frame fragments (start delimiter (SD) not followed by a valid end delimiter (ED)). A valid frame consists of only data (zero or one MAC symbols) between the SD and the ED. If an SD is detected and then, before a valid ED, the TBC detects either silence, non data (not part of the aligned ED), or bad signal, then this counter is incremented. Note that this includes abort sequences.

What is tbRxFrameFragments?

Counts frame fragments detected -- a start delimiter not followed by a valid end delimiter, including abort sequences -- indicating incomplete or corrupted frame reception.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.495.2.1.5.9.2.34
snmpwalk -v2c -c public <target> CXTokenBus-MIB::tbRxFrameFragments

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.495.2.1.5.9.2.34.1
snmpget -v2c -c public <target> CXTokenBus-MIB::tbRxFrameFragments.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> tbRxFrameFragments.1
