Feature Information
The following features were modified:
• The link connecting a core switch to a
Cisco NPV switch should be treated as
an ISL (core port) for the purpose of
congestion-drop, no-credit-drop,
slow-port monitor, and port monitor. To
accomplish this, logical-type {all | core
| edge} feature was introduced.
• The Fibre Channel congestion drop
timeout value's range was changed from
100-500 ms to 200-500 ms.
The following commands were modified:
Note From Cisco MDS NX-OS Release
8.1(1), E ports are treated as core
and F ports are treated as edge in
the system timeout
congestion-drop, system timeout
no-credit-drop, and system
timeout slowport-monitor
commands.
• system timeout congestion-drop
milliseconds logical-type {core | edge}
• system timeout no-credit-drop
milliseconds logical-type edge
• system timeout slowport-monitor
milliseconds logical-type {core | edge}
