Cisco Bug: CSCup56255 - Mod profile preamble displayed incorrectly
Apr 17, 2019
- Cisco uBR10000 Series Universal Broadband Routers
Known Affected Releases
12.2(33)SCG3 12.2(33)SCH 12.2(33)SCH1 12.2(33)SCH2
Symptom: The display of the preamble length for IM and SM bursts in "sh cable modulation-profile c x/y/z up n" is incorrect when the modulation-profile uses 16-QAM for IM and SM bursts and pre-equalization is configured on the upstream. This is a display only issue since the correct preamble length is sent in the UCDs. Conditions: 16-QAM modulation profile for the IM and SM bursts in combination with pre-equalization on the upstream.
