[c-nsp] 3750 stack(2 switches) - High CPU for an hour?

[Adam Baxter]

We have seen high CPU Caused by SNMP.. we have implemented a view that
helped. viewing the flash and license mib causes problems.

snmp-server view protect iso included
snmp-server view protect ciscoLicenseMgmtMIB excluded
snmp-server view protect ciscoFlashFileEntry excluded

snmp-server community public view protect RO

also, it might be worth implementing storm control on the client facing
switchports.
