a. If an Ethernet Ring Node is in the Forced Switch state, local SF is ignored.
Recovery for forced switching under revertive and non-revertive mode
◆
is described under the Command Usage section for the
command.
When a ring is under an FS condition, and the node at which an FS
◆
command was issued is removed or fails, the ring remains in FS state
because the FS command can only be cleared at node where the FS
command was issued. This results in an unrecoverable FS condition.
When performing a maintenance procedure (e.g., replacing, upgrading)
on a ring node (or a ring link), it is recommended that FS commands be
issued at the two adjacent ring nodes instead of directly issuing a FS
command at the ring node under maintenance in order to avoid falling
into the above mentioned unrecoverable situation.
