Is vlan850 necessary

[johnwold]

We do not use the interface vlan850 on our 6509 MFSC, but it was present by default. I beleive that it would be safe to delete it - am I right?

By default, there is NO layer 3 vlan interface on the MSFC. If you do not have VLAN 850 on your network, you can delete it by using "no interface VLAN850"
