These default settings are for parameters that affect switch-wide
operations.
Setting |
Default |

(zero) - Turns off the inactivity timer, so that an established session remains active no
matter how long a console is inactive. The inactivity timer affects only those consoles
linked to modules on which ID and password prompting is enabled. |

No
host name. |
Time zone offset |
0
(zero) - Indicates no offset from GMT. |

Maximum
Token Rotation Time (t-max-lower-bound) |
167
milliseconds
Note: The software rounds the
specified value to the nearest multiple of 5.24288 milliseconds. For example, the default
value of 167 milliseconds is interpreted by the software as 167.77216 milliseconds. |
Requested
Token Rotation Time (t_req) |
8
milliseconds
Note: The software rounds the
specified value to the nearest multiple of 20.48 microseconds. For example, the default
value of 8 milliseconds is interpreted by the software as 7.9872 milliseconds. |
Valid
Transmission Time (tvx-timer) |
2.5
milliseconds
Note: The software rounds the
specified value to the nearest multiple of 20.48 microseconds. For example, the default
value of 2.5 milliseconds is interpreted by the software as 2.51904 milliseconds. |

ATM Interface Default Settings
The following tables list the default settings for all ATM interface configurations.
Following are the types of ATM logical interfaces (ELAN or Bridge Tunnel) that are
automatically established after installation, and the conditions under which they are
active.

VSDs |
All bridge
ports on a VNswitch module are members of a default VSD. The default VSD is numbered VSD 1
and is assigned the name "Default." The VNbus tag number for the default VSD is
65. The number, name, and VNbus tag cannot be changed.
When more than one VNswitch module is resident in a MultiSwitch 900, all
ports on all VNswitch modules are, by default, members of the same (default) VSD. Ports
that are members of the default VSD operate as a traditional bridge without VLANs, except
that the bridge spans the VNbus. |
