Timeout values
The switch module timeout values determine the timeout values for all external ports on the switch. Table 22
describes the switch module timeout parameters. R_A_TOV, R_T_TOV, or E_D_TOV values must be the
same for all switch modules in the fabric.
✏ NOTE
Timeout values can be changed only if the switch module operational state is offline.
