[cisco-voip] 7940-7960 parameter 58 confusion

[Mike Armstrong]

The new 7.1(1) phone loads offer a new feature, described in the Release 
Notes 
(http://www.cisco.com/univercd/cc/td/doc/product/voice/c_ipphon/english/ipp7960/relnotes/71_100rn.htm):

>>Configurable Parameter for PCs on a VLAN

When PCs are connected to Cisco IP Phones, a new IP phone parameter enables 
phones to strip the 802.1p/q tags from packets as they exit the phone PC 
port. This parameter applies to systems that use voice VLANs with non-Cisco 
switches.

You can access the new PC VLAN parameter by pressing the Settings button, 
scrolling to and selecting Network Configuration, then scrolling down to 
parameter 58 for PC VLAN. The parameter is available only when the Admin 
VLAN is active. The parameter setting is blank if disabled, or has a value 
from 1-4094 that indicates which VLAN to strip. For example, if PC VLAN = 
123, then tags from VLAN 123 will be stripped.

The parameter setting is disabled when it is blank. If the parameter has any 
value (from 1-4094), the phone will strip tags from all VLANs. For example, 
if PC VLAN = 123, then tags from VLAN 123 and all other VLANs will be 
stripped. <<

Aside from general confusion, the last two paragraphs seem to conflict.  One 
says "if PC VLAN = 123, then tags from VLAN 123 will be stripped", the other 
says "if PC VLAN = 123, then tags from VLAN 123 and all other VLANs will be 
stripped."  What am I missing here?
