cdsIfSrcGuardVlansLow
Module: CISCO-DHCP-SNOOPING-MIB
OID (symbolic): CISCO-DHCP-SNOOPING-MIB::cdsIfSrcGuardVlansLow
OID (numeric): 1.3.6.1.4.1.9.9.380.1.6.2.1.8
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
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.
What is cdsIfSrcGuardVlansLow?
A bitmap indicating which VLANs (index 0-2047) have IP Source Guard enabled on this interface, one bit per VLAN.
