FIGURE5-11 Advanced Switch Properties Dialog

Timeo ut Value s

The switch timeout values determine the timeout values for all ports on the switch.
The timeout values must be the same for all switches in the fabric.
R_A_TOV (Resource Allocation Timeout) — the maximum time a frame could
be delayed and still be delivered. The default is 10000 milliseconds.
E_D_TOV (Error Detect Timeout) — the maximum round trip time that an
operation between two N_Ports could require. The default is 2000 milliseconds.
Note – Mismatched timeout values will disrupt the fabric. These should not be
changed unless absolutely necessary. The switch is temporarily placed offline to
change these values.
Managing System Services
The System Services dialog (FIGURE5-12) 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, command line interface, Network Time Protocol (NTP),
Common Interface Model (CIM) and Call Home. To display the System Services
dialog, open the Switch menu and select Services.
