optApsConfigTable		1.3.6.1.4.1.4515.1.11.1.1
This table contains objects to configure APS (Automatic Protection Switching) feature in a Optical Channel. APS is the ability to configure a pair of Optical connections for redundancy so that the hardware will automatically switch the active connection from working connection to the protection connection or vice versa, within 50ms, when the active connection fails. The optical connections are specified in the optXpdConnConfigTable in the SL-OPT-MIB. The APS is defined be specifying two entries in this table the backup each other. The optXpdConnConfigTable defines two entries for each dircetion of the connection. Only one of the two entries is used by the optical aps table. The direction that is used is the direction from the User to Network.

optApsConfigSwitchCommand		1.3.6.1.4.1.4515.1.11.1.1.1.17

(2) Lockout Of Protection - Prevents any of the working channels from switching to the protection connection by issuing a Lockout of Protection request [unless a request of equal priority (i.e., a Lockout of Protection) is already in effect]. (3) Forced Switch of Working (to Protection) - Switches the working channel to the protection connection unless a request of equal or higher priority is in effect, by issuing a Forced Switch request. (4) Forced Switch of Protection (to Working) - Switches the working channel back from the protection connection to the working connection unless a request of equal or higher priority is in effect, by issuing a Forced Switch request. This command applies only in the 1+1 architecture. (5) Manual Switch of Working (to Protection) - Switches the working channel to the protection connection unless a request of equal or higher priority is in effect, by issuing a Manual Switch request. (6) Manual Switch of Protection (to Working) - Switches the working channel back from the protection connection to the working connection unless a request of equal or higher priority is in effect, by issuing a Manual Switch request. This command applies only in the 1+1 architecture for the null. Reading this variable always returns zero (0).

optApsConfigSwitchReason		1.3.6.1.4.1.4515.1.11.1.1.1.18
The reason why APS switch happened. When the working connection on one end fails, its other end is told to do an APS switch. The following options in the increasing order of priority indicate what type of switch request it is. optApsRevertive : Switch back to working connection after the Wait-to-Restore interval is over, and failures are cleared. It is the lowest priority. optApsManual : Manual switch causes APS switch unless a request of equal or higher priority is in effect. optApsSignalFailureHigh : switch occured due to SD failure. optApsForceSwitch : Forced switch forces hardware to switch the active connection even if the other connection (could be working connection or protection connection) is in alarm. optApsLockOut : This is the highest priority switch. This will override all other requests. optApsLockOut : indicates that the last switchover to the working occurred because of protection lockout.
