E1 Controller Problem - Entering Holdover for Controller E1 0/0/0 and Network clock source transitioned from priority 1 to priority 10

[marcel.pludra]

Hello everybody,

i got the following Warnings on my E1 Controller:

Oct  5 06:12:32.657: %MARS_NETCLK-3-HOLDOVER: Entering Holdover for Controller E1 0/0/0
Oct  5 06:12:42.905: %MARS_NETCLK-3-HOLDOVER_TRANS: Holdover timer exceeded for Controller E1 0/0/0
Oct  5 06:12:42.905: %MARS_NETCLK-3-CLK_TRANS: Network clock source transitioned from priority 1 to priority 10
Oct  5 06:12:53.405: %MARS_NETCLK-3-CLK_TRANS: Network clock source transitioned from priority 10 to priority 1

It's an 2951 ISR with an 1MFT T1/E1 Card.

Does anyone know what this means?

Is this an provider problem?

Thanks for helping

Best regards,

Marcel

Hi Marcel,

Very well could be a provider issue.

Can you post the output of "show controllers e1"?

Solved: It was an provider issue.
