ciscoTsTransitedTrCRFs
Module: CISCO-TS-STACK-MIB
OID (symbolic): CISCO-TS-STACK-MIB::ciscoTsTransitedTrCRFs
OID (numeric): 1.3.6.1.4.1.9.5.32.6.4
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: A string of octets containing one bit per TrCRF in the management domain. The first octet corresponds to TrCRFs with ciscoTsTrCRFInfoTrCRFNumber 1 through 8; the second octet to TrCRFs 9 through 16; etc. The most significant bit of each octet corresponds to the lowest value ciscoTsTrCRFInfoTrCRFNumber in that octet. If the bit corresponding to a TrCRF is set to '1', then the TrCRF transits the local device either because it was configured to or because it was selected to automatically by the selection algorithm.
What is ciscoTsTransitedTrCRFs?
This read-only OCTET STRING (128 bytes) is a bitmask reporting which TrCRFs are actually transiting, passing through, this local device right now, whether because they were explicitly configured to in ciscoTsTransitedConfiguredTrCRFs or because of other dynamic bridging behavior. An admin comparing this against the configured set can spot TrCRFs transiting the device unexpectedly, traffic passing through that wasn't deliberately configured to, which can indicate an unintended bridging path. A bit set here with no matching bit in the configured version points at dynamically-arising transit traffic worth investigating.
