[cisco-voip] slips on NIM-8MFT-T1/E1

[Jonathan Charles]

Yeah, but I can't enable it:


ILNOVOIPISR01(config)#network-clock participate 0
G.781 based clock selection process is enabled Please unconfigure G.781
based configuration before configuring network-clock participate config
command
ILNOVOIPISR01(config)#network-clock participate 1
G.781 based clock selection process is enabled Please unconfigure G.781
based configuration before configuring network-clock participate config
command
ILNOVOIPISR01(config)#
