[c-nsp] Question - VLAN tagging Catalyst 6500 to Linux Host

[Mack McBride]

Vlans between 1005 and 1024 are used for routed links and other things in the 6500 platform.
Vlan 1005 to 1019 are used on SXH5.

This range can be larger if you are using a large number of routed links as
each routed port uses a vlan.  You can see this with:

According to Cisco Press, the problem is bigger than just VLANs 1002-1005:

"Numbers 1001 to 1024 are reserved by Cisco and cannot be configured."

I wonder if anyone has run into a problem with VLANs in this larger set?  I have not.
