Installing and Configuring the Edge Switch 2/32
60 Edge Switch 2/32 Installation Guide
R_A_TOV
Configure resource allocation time-out value (R_A_TOV) in tenth-of-a-second
increments. This variable works with the error detect time-out value (E_D_TOV)
variable to control the switch’s behavior when an error condition occurs.
Resources are allocated to a circuit when errors are detected and are not released
for reuse until the time set by the R_A_TOV value expires. The default value is
100 tenths (10 seconds). Set a value from 10 tenths through 1200 tenths (1 through
120 seconds).
Note: Set the same value for R_A_TOV on all directors and switches in a multiswitch
fabric. If the value is not the same on all units, the fabric segments. Also, the value for
R_A_TOV must be greater than the value configured for E_D_TOV.
E_D_TOV
Adjust the E_D_TOV in tenth-of-a-second increments. An error condition occurs
when an expected response is not received within the time limit set by this value.
The default value is 20 tenths (2 seconds). Set a value from 2 tenths through 600
tenths (.2 through 60 seconds).
Note: Set the same value for E_D_TOV on all switches and directors in a multiswitch
fabric. If the value is not the same, the fabric segments.
Switch Priority
Setting this value determines the principal switch for the multiswitch fabric.
Choose
Principal (highest priority), Default , or Never Principal (lowest priority)
from the Switch Priority drop-down list.
Setting these priority values determines the principal switch selected for the
multiswitch fabric. For example, if you have three switches in the fabric and set
one as
Principal , one as Default , and one as Never Principal , the unit set to
Principal becomes the principal switch in the fabric.
