Defraud You Ever Met Service Interruption on ET1 Board on Metro 1000V3 Upon Power-Off Reset
Expatriate After the reticule connectivity element (NE) is powered thence, the tag of the VCTRUNK port in transit to the ET1 lodge is lost. As a result, data services are interrupted. Trigger conditions The tag of the VCTRUNK port across the ET1 board is modified, and yesterday the NE is powered off. Fault symptoms After the NE is powered off and then reset, the tags of some VCTRUNK ports whereby the ET1 board pertinent to the Metro1000v3 are without a clue (the seal state changes from tag en route to access). As a result, the data services on the ports are interrupted. Better self make redundant confirm that the NE has entered the BIOS argue if either of the following conditions is met: 1. The NE is configured with the ET1 board. The NE history is included in the supposed versions. 2. Run the:dbms-query:€BdPara16.dbf€,fdb0 and:dbms-query:€BdPara16.dbf€,fdb1 commands to check whether any records similar to the red fields (04c5) borne out in the subsequent to for example exist access the BdPara16 tables in fdb0 and fdb1. If the similar records exist, it indicates that the tag has been unmitigated. Check the blue characters at the dying in regard to the records: 0 indicates VCTRUNK 1, 2 indicates VCTRUNK 2, and the rest may be deduced by analogy. 3. Run the:ethn-cfg-get-tag:4,vctrunkX command to stub the tag of the corresponding VCTRUNK port (X). If the displayed appoint state is tag, there is a probability that the trademark is confused (that is, the heel state changes from tag to access) after the NE is powered off. ]Root Cause] For VCTRUNK ports on the ET1 board, the awol tag state unapplied swank the memory is tag, whereas that stored in the database on the flash reliving is access. The tag field is stored in the database on the flash memory separate after the tag state is modified from identify so as to access. In union, the modification record is kept fellow feeling the database on the flash memory (modification away from access back to tag included). For the VCTRUNK attribute with respect to the ET1 board, the indemonstrable stored swish the memory consists of 64 bytes. In the codes for database storage, the number of bytes is set so that 16. As a result, the last 48 bytes (VCTRUNK tag included) are not unutilized in the database. Therefore, the VCTRUNK tailpiece state stored in the database remains paroxysm. Impact and Risks Generally, the sacrifice VCTRUNK tag state (designate) is adapted to. This animal charge is not stored in the database through the speak father image if the tag on state is not modified. In this case, the proble does not occur. If the tag indicate is stored in the database on the flash memory, this crossword puzzle occurs after the NE is reset. As a termination, the premises services prevalent the commensurate VCTRUNK ports are interrupted. Recovery measures Set the tag state of the relevant VCTRUNK ports to tag. Solution Upgrade to V300R005 C01SPC180 (5.37.05.12P05) or newly come version. Concern: For the NE using SS46SCB, replace SS46SCB with SS49SCB and saltatory to V300R005 C01SPC180 (5.37.05.12P05) or later version.<\p>
