20800007	E4	L2LD : ChGr(<channel group number>) loop detection from port(<switch no.>/<nif no.>/<port no.>).
20800007	A loop failure was detected. The loop failure detection log is not output for the same port or channel group for one minute after the loop failure detection log (20800005 to 20800008) is output. <channel group number>: Channel group number <switch no.>/<nif no.>/<port no.>: Switch number/NIF number/port number [Action] Check the network configuration.

20800008	A loop failure was detected. The loop failure detection log is not output for the same port or channel group for one minute after the loop failure detection log (20800005 to 20800008) is output. <channel group number>: Channel group number [Action] Check the network configuration.
20800009	E4	L2LD : Port(<switch no.>/<nif no.>/<port no.>) activate by automatic restoration of the L2loop detection function.
20800009	The port state inactive was cleared due to automatic recovery of the L2 loop detection function. <switch no.>/<nif no.>/<port no.>: Switch number/NIF number/port number [Action] None.
20800010	E4	L2LD : ChGr(<channel group number>) activate by automatic restoration of the L2loop detection function.
20800010	The port state inactive was cleared due to automatic recovery of the L2 loop detection function. <channel group number>: Channel group number [Action] None.
20800011	E4	L2LD : L2loop detection frame cannot be sent in the port where capacity was exceeded.
20800011	The number of ports that can send L2 loop detection frames exceed the capacity limit. Ports exceeding the capacity limit cannot send L2 loop detection frames. [Action] Decrease the number of ports sending L2 loop detection frames.
