CISCO DHCP SNOOPING If Source Guard Vlans High

1.3.6.1.4.1.9.9.380.1.6.2.1.9

A string of octets containing one bit per VLAN for VLANs with VlanIndex value of 2048 to 4095. 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. 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.
