Cisco Bug: CSCta71839 - Ping failure observed after over-weekend traffic and CM reset
Feb 08, 2017
- Cisco uBR10000 Series Universal Broadband Routers
Known Affected Releases
Symptom: Wideband Cable Modems are w-online but cannot be pinged. DOCSIS pings to CMs can be done successfully. This might result in loss of IP connectivity for the modems. Conditions: This problem was observed in Bighorn. Roger's TB had around 300+ modems on the SPA and there was a script being run that did clear cable modem all delete every 20 minutes. This caused a large number of IPCs to the jacket. In some cases the IPCs to clear DSID didn't all arrive reliably at the jacket. So, a subsequent modem coming online using the DSID would have non-zero seq num in first packet.
