Changes
Inserted one or more SFP+ modules (e.g. 10GB-SR-SFPP, 10GB-LR-SFPP) into the system.

Symptoms
Upon system boot-up, for each such module an "
code:

Unsupported pluggable module

" message is written to syslog ('
code:

show support

', '
code:

show logging buffer

'); for example:
    <[code]162[/code]>[code]Sep 24 09:39:07 10.20.44.15-1 EDB[188769128]: edb_bxs.c(1935) 36 %% Unsupported pluggable module detected on tg.1.49[/code]
Cause
The system is issuing the message rather than waiting out a delay in local SFP+ information retrieval.
