Field descriptions
Aps group—Name of the APS group for which information is displayed
Current Conditions—Current state of the group
Rx (K1/K2)—Value, meaning, and channel number of the received K1 and K2 bytes
(see Table 7 on page 74 and Table 8 on page 74)
Tx (K1/K2)—Value, meaning, and channel number of the transmitted K1 and K2 bytes
(see Table 7 on page 74 and Table 8 on page 74)
Counters—Statistics for APS group
ModeMismatch—Number of differences detected in the local and remote switching
mechanisms (unidirectional or bidirectional modes)
ChanMismatch—Number of differences detected between the number of the
channel in the transmitted K1 byte and the number of the channel in the received
K2 byte
PSBF—Number of protection switching byte failures detected (no 3 consecutive
SONET/SDH frames out of the last 12 contain identical K1 bytes)
FEPLF—Number of far-end protection line failures (signal failures detected on
protect interface)
Aps channel—Number, interface specifier (in slot/port format), and protect/working
designation of the APS channel for which information is displayed
aps-protect—Identifies the protect interface
aps-working—Identifies the working interface
Current Conditions—Current state of the interface for this channel
lockedOut—Indicates that the router is configured to prevent the protect interface
from taking over if the primary interface fails
