Feb 08, 2017
- Cisco uBR10000 Series Universal Broadband Routers
Known Affected Releases
Symptom: The 520U card CPU usage can be high for a number of reasons. One reason is that when an upstream is shared with a remote SPA channel using the following configuration line, there is added CPU expense to sending DOCSIS MAP messages to those channels: Cable<slot>/<subslot>/<index> downstream Modular-Cable <slot>/<bay>/<port> rf-channel <channel> The 520H card also uses more CPU for the same functionality, but due to a faster CPU with larger L2 cache, the CPU usage is not as noticeable on an H card. Conditions: 520 U cards used with Modena SPAs.
