Scenario: 400 user LAN (30 VLANs - L2 througout - L3 routing at the core) with about 30% of the users having small 5-port gig switches because they must run 3-4 machines. Physically we can only deliver 2 ports/user and each user has a Cisco IP phone. Current policy allows end-users to use these small switches in their offices.
Question: Is the following config safe to use globally on our access switches (3750G L2 running 12.37.SE1)?
spanning-tree mode rapid-pvst
spanning-tree loopguard default
spanning-tree portfast bpduguard default
spanning-tree extend system-id
switchport access vlan 2
switchport voice vlan 20
srr-queue bandwidth share 10 10 60 20
srr-queue bandwidth shape 10 0 0 0

Thanks in advance,
