portCopyHiVlanMask

This object affects the way VLAN-based traffic is copied from
a switch source port, for the indicated port copy operation. 
It is used in tandem with the portCopyLoVlanMask to 
identify all possible 4096 IEEE 802.1Q VLAN ID values. 
This object is used to select or deselect VLAN IDs 
2048 though 4095. 
              
If this object contains a zero-length string, or none 
of the octets contain a non-zero value, and the 
associated portCopyLoVlanMask is not instantiated, 
contains a zero-length string, or contains only 
zero-valued octets, then network traffic will not 
be filtered, based on IEEE 802.1Q or ISL VLAN ID, before 
it is copied to the indicated destination port. 
              
If this object has a non-zero length, and at least 
one octet contains a non-zero value, or the 
portCopyLoVlanMask contains at least one non-zero octet, 
then traffic will be filtered, based on the indicated 
IEEE 802.1Q or ISL VLAN ID, before it is copied to the 
indicated destination port. Only frames (tagged or 
untagged) which match the indicated VLAN ID(s) will be 
copied to the indicated destination port. 
              
VLAN IDs are encoded as a string of octets containing 
one bit per VLAN to be included in the port copy operation. 
The first octet corresponds to VLANs with VlanIndex values 
of 2048 through 2055; the second octet to VLANs 2056 through 
2063; etc. The most significant bit of each octet corresponds 
to the lowest value VlanIndex in that octet.  If the bit 
corresponding to a VLAN is set to '1', then the traffic 
associated with that VLAN will be selected for the 
indicated port copy operation. 
              
Note that if the length of this string is less than 
256 octets, any 'missing' octets are assumed to contain 
the value zero. An NMS may omit any zero-valued octets 
from the end of this string in order to reduce SetPDU size, 
and the agent may also omit zero-valued trailing octets, 
to reduce the size of GetResponse PDUs. 
              
The creation and deletion of instances of this object is 
controlled by the portCopyStatus object found in the 
augmented portCopyEntry.  It is an implementation-specific 
matter as to how many VLANs may be selected from a 
particular physical source port at any one time, or whether 
this object may be modified while the associated 
portCopyStatus object is equal to 'active'.
