Network Synchronization Support Configuring Network Synchronization Table 4 Troubleshooting Scenarios (continued) Problem Solution Incorrect clock limit set or queue limit disabled mode • Verify that there are no alarms on the interfaces. Use the show network-clock synchronization detail RP command to confirm. • Use the show network-clock synchronization command to confirm if the system is in revertive mode or nonrevertive mode and verify the nonrevertive configurations as shown in this example: RouterB#show network-clocks synchronization Symbols: En - Enable, Dis - Disable, Adis - Admin Disable NA - Not Applicable * - Synchronization source selected # - Synchronization source force selected & - Synchronization source manually switched Automatic selection process : Enable Equipment Clock : 1544 (EEC-Option2) Clock Mode : QL-Enable ESMC : Enabled SSM Option : GEN1 T0 : External R0 t1 esf Hold-off (global) : 300 ms Wait-to-restore (global) : 300 sec Tsm Delay : 180 ms Revertive : No Force Switch: FALSE Manual Switch: FALSE Number of synchronization sources: 2 sm(netsync NETCLK_QL_ENABLE), running yes, state 1A Last transition recorded: (src_rem)-> 1A (src_added)-> 1A (src_rem)-> 1A (src_added)-> 1A (ql_change)-> 1A (sf_change)-> 1A (force_sw)-> 1C (clear_sw)-> 1A (sf_change)-> 1A (sf_change)-> 1A Incorrect QL values Use the network clock synchronization SSM (option 1 |option 2) command observed when you use to confirm that there is no framing mismatch. Use the show run interface the show command to validate the framing for a specific interface. For the SSM option network-clock 1, framing should be SDH or E1, and for SSM option 2, it should be T1. synchronization detail command.
