| Description | A string of octets containing one bit per VLAN for
VLANs with VlanIndex value of 0 to 2047. The first
octet corresponds to VLANs with VlanIndex values
of 0 through 7; the second octet to VLANs 8 through
15; etc. The most significant bit of each octet
corresponds to the lowest value VlanIndex in that octet.
For each VLAN, if Source Guard feature is enabled then
the bit corresponding to that VLAN is set to '1'.
Note that if the length of this string is less than
256 octets, any 'missing' octets are assumed to contain
the value zero. A 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. |
