Timeout values

The switch timeout values determine the timeout values for all ports on the switch. Table 13 describes the switch timeout parameters. The timeout values must be the same for all switches in the fabric.

NOTE: Mismatched timeout values will disrupt the fabric. These should not be changed unless absolutely necessary. Therefore, the switch must be offline to change these values. Use the Switch Properties dialog to take the switch offline.

Table 13 Timeout values

Parameter

Description

 

 

R_A_TOV

Resource Allocation Timeout — represents the maximum time a frame

 

could be delayed in the Fabric and still be delivered. The default is

 

10000 milliseconds.

 

 

E_D_TOV

Error Detect Timeout — represents the maximum round trip time that an

 

operation between two N_Ports could require. The default is 2000

 

milliseconds.

 

 

Interop mode for zoning

The interop mode permits interoperation with FC-SW-2 compliant and McDATA switches in McDATA Fabric Mode. The default interop mode is Standard.

Use the Standard option to connect to FC-SW-2 compliant switches and McDATA switches in Open Fabric Mode.

Use the McDATA Fabric Mode option to connect to McDATA switches in McDATA Fabric Mode.

System Services dialog

The System Services dialog provides a central location for you to enable or disable any of the external user services such as Simple Network Management Protocol (SNMP), Secure Sockets Layer (SSL), Secure SHell (SSH), embedded switch management application (McDATA Web Server), Command Line Interface (CLI), Network Time Protocol (NTP), and Common Information Model (CIM). Select Switch > Services to display the System Services dialog.
