primaryClockSource
Module: CISCO-WAN-AXIPOP-MIB
OID (symbolic): CISCO-WAN-AXIPOP-MIB::primaryClockSource
OID (numeric): 1.3.6.1.4.1.351.110.3.8.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Primary reference for the clock source. Each of these codes are to be interpreted as follows: liu-rclk0: Recovered clock from physical line 0 liu-rclk1: Recovered clock from physical line 1 liu-rclk2: Recovered clock from physical line 2 liu-rclk3: Recovered clock from physical line 3 liu-rclk4: Recovered clock from physical line 4 liu-rclk5: Recovered clock from physical line 5 liu-rclk6: Recovered clock from physical line 6 liu-rclk7: Recovered clock from physical line 7 dsx3: Recovered clock from the T3/E3 line bp8clk: Back-plane 8 KHz clock
What is primaryClockSource?
This read-write enumerated setting selects which physical source - recovered clock from one of the LIU physical lines 0-7, the DSX3 interface, or the backplane clock (bp8clk) - serves as the card's primary timing reference. Admins configure this because ATM/WAN cards need a stable, agreed clock source across the network to avoid cell slips and synchronization errors, and the primary source is the first choice before falling back to a secondary. For example, an admin might set primaryClockSource to liu-rclk0 to derive timing from the recovered clock on physical line 0, which is connected to the network's master timing source.
