System services, Timeout values, Interop mode | HP SAN specs

Timeout values

The switch timeout values determine the timeout values for all ports on the switch. Table 12 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 12 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

Interop mode permits interoperability with other switches in the following environments:

•Standard: Permits interoperability with FC-SW-2 compliant switches and McDATA switches in Open Fabric Mode. Valid domain IDs are 97–127.

•McDATA Fabric Mode: Permits interoperability with other McDATA switches in McDATA Fabric Mode. Valid domain IDs are 1–31.

Enabling the 239 Domain Support option extends the valid domain IDs to 1–239 for both Standard and McDATA Fabric Mode settings. However, all switches in the fabric must support 239 domain IDs.

System services

The System Services dialog provides a central location for you to enable or disable any of the external user services such as SNMP, Secure Sockets Layer (SSL), Secure SHell (SSH), embedded switch management

application (McDATA Web Server or Element Manager), CLI, Network Time Protocol (NTP), and Common Information Model (CIM). Select Switch > Services to display the System Services dialog shown in

Figure 32.
