The option for
Fast POST in the Management Module Advanced Setup for I/O Modules only
affects how thoroughly the diagnostics are run during POST, which in turn affects how fast the
switch boots but does not ultimately affect any management or data paths on the IGESM.
Figure 9-2 Advanced settings for each IGESM (on the Management Module)
These are ways that one can detect Management Module settings from commands and
actions performed on the Cisco Systems IGESM:
򐂰 How can I tell whether the External ports setting is set to Enabled or Disabled?
If you attempt to go into one of the external interfaces and perform no shut on the IGESM,
and it returns a Shutdown is not allowed on this interface message, then the setting
on the Management Module is Disabled (Figure 9-3). To permit a no shut to work on ports
17 through 20, you must go into the Management Module and set this value to Enabled.
Figure 9-3 Detecting the setting of external ports on the Management Module
򐂰 How can I tell how External management over all ports and Preserve new IP configuration
on all resets are set?
See Figure 9-4 on page 236. Use the sh platform summary command to see these
values. To change any of these values, you must log on to the Management Module and
make the appropriate change therein.
• Unable to enable external ports from switch
switch(config)#int g0/17
switch(config-if)#no shut
% Shutdown not allowed on this interface.
• Must enable External ports in advanced setup in MM
